Description

Technical Field

[0001] The present invention relates to the technical field of host management, and in particular to a host management method, device, communication equipment and storage medium. Background Art

[0002] While the openness of storage systems facilitates host access, it also poses a potential threat to data security. Without effective control mechanisms, all hosts can access storage resources on the storage system, increasing the risk of data leakage and posing a challenge to the overall security of the storage system. Therefore, efficient and intelligent host management is essential.

[0003] Existing methods for managing hosts primarily rely on manual acquisition of host status, configuration, management, and maintenance. This process is not only time-consuming, but also inaccurately captures host status, leading to users being unable to access storage system resources through the host. Consequently, existing methods for managing hosts suffer from low efficiency and accuracy. Summary of the Invention

[0095] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, each embodiment of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be understood by those skilled in the art that in each embodiment of the present invention, many technical details are provided to enable the reader to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical solutions claimed in this application can be implemented. The division of the following embodiments is for convenience of description and should not constitute any limitation on the specific implementation of the present invention. The various embodiments can be combined with each other and referenced to each other under the premise that there is no contradiction.

[0096] Reference Figure 1 , shows one of the steps of a flow chart of a host management method provided by an embodiment of the present invention, which is applied to a dual-controller storage cluster. The dual-controller storage cluster includes a first controller and a second controller. The method may include:

[0097] Step 101: Predetermine a candidate host list of a first controller and a candidate host list of a second controller through a switch or a host, wherein the candidate host list of the first controller and the candidate host list of the second controller both include a plurality of candidate hosts and multicast information of the plurality of candidate hosts.

[0098] It should be noted that, in the embodiment of the present invention, Figure 2 As shown, the host management system includes hosts, switches, and a dual-controller storage cluster. The dual-controller storage cluster and hosts can be connected via switches, or directly to each other.

[0099] If the dual-controller storage cluster and the host are connected via a switch, the dual-controller storage cluster can determine the candidate host list of the first controller and the candidate host list of the second controller through the switch. If the dual-controller storage cluster and the host are directly connected, the dual-controller storage cluster can directly determine the candidate host list of the first controller and the candidate host list of the second controller through the host. The candidate host list of the first controller and the candidate host list of the second controller both include multiple candidate hosts and multicast information about multiple candidate hosts.

[0100] Step 102: For any controller, determine the target host to be selected from the list of hosts to be selected, and store the target host to the access control list to obtain the access control list of the first controller and the access control list of the second controller, wherein the access control list of the first controller and the access control list of the second controller both include several target hosts to be selected and multicast information of several target hosts to be selected.

[0101] It should be noted that in the embodiment of the present invention, the dual-control storage cluster provides a GUI (Graphical User Interface) to facilitate users to add candidate hosts in the candidate host list to the access control list through the graphical user interface. The candidate hosts added to the access control list are the target candidate hosts.

[0102] Specifically, for any controller, the dual-control storage cluster responds to the user's instruction to add a candidate host, obtains the candidate host list corresponding to the controller, selects the target candidate host from the candidate host list, and adds the target candidate host to the access control list, thereby obtaining the access control lists corresponding to the controllers, that is, the access control list of the first controller and the access control list of the second controller. When the target candidate host is added to the access control list, the multicast information of the target candidate host is also added to the access control list. Therefore, the access control list of the first controller and the access control list of the second controller both include several target candidate hosts and multicast information of several target candidate hosts. It should be noted that the target candidate host in the access control list can be used to normally access the storage resources in the dual-control storage cluster.

[0103] Among them, after adding the target candidate host to the access control list, the dual-controller storage cluster needs to delete the target candidate host and its multicast information in the candidate host list corresponding to the controller to ensure that the target candidate host can be accessed normally when it automatically reconnects after an unexpected disconnection.

[0104] Step 103 : Classify the target host to be selected according to the access control list of the first controller and the access control list of the second controller to obtain a classification result of the target host to be selected.

[0105] It should be noted that in an embodiment of the present invention, when the access control list of the first controller and the access control list of the second controller are obtained, the target candidate host is classified according to the access control list of the first controller and the access control list of the second controller to obtain the target candidate host classification result.

[0106] Step 104 : Determine a target host according to the classification result of the target candidate hosts, wherein the target host is used to access storage resources in the dual-controller storage cluster.

[0107] It should be noted that in this embodiment of the present invention, the dual-controller storage cluster can select a target host based on the target candidate host classification results in response to the user's host selection instruction. After determining the target host, the user can use the target host to access storage resources in the dual-controller storage cluster.

[0108] The present invention automatically determines the target candidate host from the candidate host list through a dual-control storage cluster and stores it in an access control list, ensuring that only the hosts in the access control list can access the storage resources in the dual-control storage cluster, thereby realizing the management of the host. This process avoids the inaccuracy of manually obtaining the host status, and also reduces the time-consuming manual configuration, thereby improving the efficiency and accuracy of host management. The present invention determines the candidate host list through two methods, namely, a switch or a host, which can adapt to different deployment scenarios and network structures, and improves the versatility, scalability and flexibility of determining the candidate host list. The present invention automatically determines the candidate host list through the dual-control storage side, reducing the need for manual intervention and improving the convenience and efficiency of operation. In addition, the present invention classifies the target candidate host through the dual-control storage cluster to obtain the target candidate host classification result, so that the user can intuitively select the target host according to the target candidate host classification result, which not only improves the user experience, but also improves the security and reliability of accessing storage resources through the target host.

[0109] Furthermore, in this embodiment of the present invention, step 101 may further include the following steps:

[0110] The host table corresponding to each controller is obtained through the switch, wherein the host table includes a plurality of hosts and multicast information of the plurality of hosts.

[0111] For any controller, determine a number of candidate hosts and their multicast information from the host table corresponding to the controller, and store the number of candidate hosts and their multicast information in a candidate host list to obtain the candidate host list of the first controller and the candidate host list of the second controller. Or,

[0112] For any controller, obtain the host's multicast information through the host.

[0113] Parse the multicast information of the host to obtain the parsed multicast information.

[0114] The host and the multicast information parsed by the host are stored in a candidate host list, and the candidate host list of the first controller and the candidate host list of the second controller are obtained.

[0115] It should be noted that, in an embodiment of the present invention, if the dual-control storage cluster is connected to the host through a switch, the dual-control storage cluster can determine the candidate host list of the first controller and the candidate host list of the second controller through the switch. Specifically, the host table corresponding to each controller is obtained through the switch, that is, the host table of the first controller and the host table of the second controller, wherein the host table includes a number of hosts and multicast information of the number of hosts. In the case of obtaining the host table corresponding to each controller, for any controller, the dual-control storage cluster selects a number of hosts and multicast information of the number of hosts from the host table corresponding to the controller, and the selected host is the candidate host, and the selected number of candidate hosts and the multicast information of the number of candidate hosts are stored in the candidate host list, thereby obtaining the candidate host list corresponding to each controller, that is, the candidate host list of the first controller and the candidate host list of the second controller.

[0116] If the dual-controller storage cluster is directly connected to the host, the dual-controller storage cluster can directly determine the candidate host list for the first controller and the candidate host list for the second controller through the host. Specifically, for any controller, the dual-controller storage cluster can directly obtain the host's multicast information through the host. After obtaining the host's multicast information, it parses the host's multicast information to obtain the parsed multicast information. The host and the parsed multicast information corresponding to the host are stored in the candidate host list. This allows the candidate host list corresponding to each controller to be obtained, namely the candidate host list for the first controller and the candidate host list for the second controller.

[0117] The present invention determines the candidate host list through either a switch or a host, adapting to different deployment scenarios and network structures, thereby improving the versatility, scalability, and flexibility of determining the candidate host list. Furthermore, the present invention automatically determines the candidate host list through the dual-control storage side, reducing the need for manual intervention and improving operational convenience and efficiency.

[0118] Furthermore, in the embodiment of the present invention, the following steps may be further included after step 101:

[0119] For any controller, the multicast information of the host is obtained through the switch according to the preset time.

[0120] If the switch receives the multicast information sent by the host within the preset time, it is determined that the host is online.

[0121] The multicast information of the host is stored in the candidate host list, and an updated candidate host list corresponding to each controller is obtained.

[0122] If the switch does not receive the multicast information sent by the host within the preset time, it is determined that the host is offline.

[0123] Delete the multicast information of the host in the candidate host list to obtain the updated candidate host list corresponding to each controller. Or,

[0124] For any controller, obtain the host's multicast information through the host according to the preset time.

[0125] If the dual-controller storage cluster receives the multicast information sent by the host within the preset time, it determines that the host is online.

[0126] The multicast information of the host is stored in the candidate host list, and an updated candidate host list corresponding to each controller is obtained.

[0127] If the dual-controller storage cluster does not receive the multicast information sent by the host within the preset time, it determines that the host is offline.

[0128] The multicast information of the host in the candidate host list is deleted to obtain an updated candidate host list corresponding to each controller.

[0129] It should be noted that, in the embodiment of the present invention, when the list of hosts to be selected corresponding to each controller is determined, the list of hosts to be selected needs to be updated on time according to the online and offline information of the hosts.

[0130] Among them, if the dual-control storage cluster obtains the host's online and offline information through the switch, then the specific implementation process of updating the candidate host list based on the host's online and offline information is as follows: If the dual-control storage cluster and the host are connected through the switch, the host will send the host's multicast information to the switch according to the preset time. If the dual-control storage cluster can receive the multicast information sent by the host through the switch according to the preset time, it is determined that the host is online, and the host and the host's multicast information are stored in the candidate host list, and then the updated candidate host list corresponding to each controller can be obtained. If the dual-control storage cluster cannot receive the multicast information sent by the host through the switch according to the preset time, it is determined that the host is offline, and the host and the host's multicast information are deleted from the candidate host list, and then the updated candidate host list corresponding to each controller can be obtained.

[0131] If the dual-controller storage cluster is directly connected to the host, the host will periodically send its multicast information to the dual-controller storage cluster at a preset time. If the dual-controller storage cluster is able to receive the multicast information sent by the host at the preset time, the host is determined to be online and the host and its multicast information are stored in the candidate host list, thereby obtaining an updated candidate host list corresponding to each controller. If the dual-controller storage cluster is unable to receive the multicast information sent by the host at the preset time, the host is determined to be offline and the host and its multicast information are deleted from the candidate host list, thereby obtaining an updated candidate host list corresponding to each controller.

[0132] The present invention monitors the online and offline information of the host in real time and updates the list of candidate hosts regularly according to the online and offline information of the host. This not only avoids host management errors caused by changes in the online and offline information of the host, but also frees up storage space in the list of candidate hosts, thereby avoiding waste of storage space in the list of candidate hosts.

[0133] Furthermore, if Figure 3 FIG. 2 shows a second flowchart of the host management method provided by an embodiment of the present invention. In the embodiment of the present invention, step 103 may further include the following steps:

[0134] Step 301: If the target host to be selected is in the access control list of the first controller and the access control list of the second controller, the target host to be selected is determined to be a standard host.

[0135] Step 302: If the target candidate host is in the access control list of the first controller or the access control list of the second controller, determine that the target candidate host is a downgraded host.

[0136] Step 303: If the target candidate host is not in the access control list of the first controller and the access control list of the second controller, it is determined that the target candidate host is an offline host.

[0137] It should be noted that, in an embodiment of the present invention, a dual-controller storage cluster can classify target candidate hosts based on the access control list of the first controller and the access control list of the second controller. The specific implementation process for obtaining the target candidate host classification result is as follows: if the target candidate host exists in both the access control list of the first controller and the access control list of the second controller, it means that both data links of the first controller and the second controller can control the target candidate host to obtain storage resources. If one controller fails, the other controller can still control the target candidate host to obtain storage resources. The target candidate host is determined to be a standard host. If the target candidate host exists only in the access control list of the first controller, it means that only the data link of the first controller can control the target candidate host to obtain storage resources. If the first controller fails, the target candidate host cannot obtain storage resources through the target candidate host. The target candidate host is determined to be a degraded host. If the target candidate host exists only in the access control list of the second controller, it means that only the data link of the second controller can control the target candidate host to obtain storage resources. If the second controller fails, the target candidate host cannot obtain storage resources through the target candidate host. The target candidate host is determined to be a degraded host. If the target candidate host does not exist in the access control list of the first controller or the access control list of the second controller, the target candidate host is determined to be an offline host, and storage resources in the dual-controller storage cluster cannot be obtained through the target candidate host.

[0138] The present invention classifies target candidate hosts through a dual-control storage cluster to obtain target candidate host classification results, so that users can intuitively and targetedly select target hosts based on the target candidate host classification results, which not only improves the user experience, but also improves the security and reliability of accessing storage resources through the target host.

[0139] Furthermore, in the embodiment of the present invention, after step 101, the method may further include the following steps:

[0140] If the host to be selected is in the host to be selected list of the first controller and the host to be selected list of the second controller, the host to be selected is determined to be a standard host to be selected.

[0141] If the candidate host is in the candidate host list of the first controller or the candidate host list of the second controller, the candidate host is determined to be a downgraded candidate host.

[0142] It should be noted that, in an embodiment of the present invention, when the dual-controller storage cluster determines the candidate host list of the first controller and the candidate host list of the second controller through a switch or a host, the dual-controller storage cluster can classify the candidate hosts according to the candidate host list of the first controller and the candidate host list of the second controller to obtain the candidate host classification result.

[0143] Among them, the dual-controller storage cluster can classify the candidates according to the candidate host list of the first controller and the candidate host list of the second controller, and the specific implementation process of obtaining the candidate host classification result is: if the candidate host exists in the candidate host list of the first controller and the candidate host list of the second controller at the same time, it means that both the data links of the first controller and the second controller can control the candidate host, and the candidate host is determined to be a standard candidate host. If the candidate host only exists in the candidate host list of the first controller, it means that only the data link of the first controller can control the candidate host, and the candidate host is determined to be a downgraded candidate host. If the candidate host only exists in the candidate host list of the second controller, it means that only the data link of the second controller can control the candidate host, and the candidate host is determined to be a downgraded candidate host.

[0144] The present invention classifies the candidate hosts through a dual-control storage cluster to obtain the candidate host classification results, so that users can intuitively select the candidate hosts according to the candidate host classification results and add the candidate hosts to the access control list, which not only improves the user experience, but also improves the reliability and convenience of host management.

[0145] Reference Figure 4 , shows one of the step flow charts of another host management method provided by an embodiment of the present invention, which is applied to a host. The method may include:

[0146] Step 401: Get the current operating system.

[0147] Step 402: Install the software environment of the host according to the current operating system.

[0148] It should be noted that, in the embodiment of the present invention, the installation of the software environment of the host in the prior art needs to rely on manual installation, which leads to the problem of low efficiency of software environment installation.

[0149] In order to solve the problem of low efficiency in software environment installation, this technical solution needs to obtain the current operating system of the host in advance and automatically install the software environment of the host through the current operating system.

[0150] Step 403: When the software environment of the host is installed, the multicast information of the host is obtained, wherein the multicast information of the host includes the Internet Protocol address of the host port and the namespace qualifier name of the host.

[0151] Step 404: Send the host's multicast information to the switch or the dual-controller storage cluster at a preset time; wherein the switch is used to store the host's multicast information in a host table and send the host table to the dual-controller storage cluster; the dual-controller storage cluster is used to determine the candidate host list of the first controller and the candidate host list of the second controller through the switch or the host; for any controller, determine the target candidate host from the candidate host list, and store the target candidate host in the access control list to obtain the access control list of the first controller and the access control list of the second controller; classify the target candidate host according to the access control list of the first controller and the access control list of the second controller to obtain the classification result of the target candidate host; and determine the target host according to the classification result of the target candidate host.

[0152] It should be noted that, in an embodiment of the present invention, when the software environment of the host is installed, the multicast information of the host is obtained, and the multicast information of the host is sent to the switch or the dual-control storage cluster through the multicast tool at a preset time. The multicast information of the host includes the Internet Protocol address of the host port and the namespace qualifier name of the host. The specific implementation process of obtaining the multicast information of the host is as follows: for the host, configure the Internet Protocol address of the host port. When the Internet Protocol address of the host port is configured, the namespace qualifier name of the host is obtained through the command tool. The Internet Protocol address of the host port and the namespace qualifier name of the host constitute the multicast information of the host.

[0153] It should be noted that if the host reconfigures the Internet Protocol address of the host port, the Internet Protocol address of the host port in the multicast information is updated to obtain updated multicast information, and the updated multicast information is sent to the switch or dual-controller storage cluster.

[0154] When the switch receives multicast information from the host, it stores the multicast information in the host table. The dual-controller storage cluster can subscribe to the host table from the switch.

[0155] The dual-control storage cluster can determine the candidate host list of the first controller and the candidate host list of the second controller through a switch or a host. For any controller, the dual-control storage cluster responds to the user's candidate host addition instruction, obtains the candidate host list corresponding to the controller, selects the target candidate host from the candidate host list, and adds the target candidate host to the access control list, thereby obtaining the access control lists corresponding to the controllers, that is, the access control list of the first controller and the access control list of the second controller. When adding the target candidate host to the access control list, the multicast information of the target candidate host is also added to the access control list. Therefore, the access control list of the first controller and the access control list of the second controller both include several target candidate hosts and multicast information of several target candidate hosts. It should be noted that the target candidate host in the access control list can be used to normally access the storage resources in the dual-control storage cluster.

[0156] Among them, after adding the target candidate host to the access control list, the dual-controller storage cluster needs to delete the target candidate host and its multicast information in the candidate host list corresponding to the controller to ensure that the target candidate host can be accessed normally when it automatically reconnects after an unexpected disconnection.

[0157] When the dual-controller storage cluster obtains the access control list of the first controller and the access control list of the second controller, the dual-controller storage cluster classifies the target candidate host according to the access control list of the first controller and the access control list of the second controller to obtain a target candidate host classification result.

[0158] After obtaining the target candidate host classification result, the dual-controller storage cluster responds to the user's host selection instruction and selects a target host based on the target candidate host classification result. After determining the target host, the user can use the target host to access storage resources in the dual-controller storage cluster.

[0159] The present invention automatically installs the host's software environment through the host's current operating system, eliminating the need for manual installation of the software environment and significantly improving the efficiency and accuracy of software environment installation. Furthermore, the present invention automatically determines the target host from the candidate host list through the dual-control storage cluster and stores it in the access control list, ensuring that only hosts in the access control list can access the storage resources in the dual-control storage cluster, thereby achieving host management. This process avoids the inaccuracy of manually obtaining host status, reduces the time-consuming manual configuration, and improves the efficiency and accuracy of host management.

[0160] Furthermore, if Figure 5FIG. 4 shows a second flowchart of another host management method provided by an embodiment of the present invention. In the embodiment of the present invention, step 402 may further include the following steps:

[0161] Step 501: Install the driver according to the current operating system.

[0162] Step 502: When the driver is installed, the command tool is installed according to the current operating system.

[0163] Step 503: When the command tool is installed, the multicast tool is installed according to the current operating system.

[0164] Step 504: When the multicast tool is installed, the multipath tool is installed according to the current operating system.

[0165] It should be noted that, in the embodiment of the present invention, the host is a ROCE-NVME host.

[0166] The specific implementation process for installing the host software environment based on the current operating system is as follows: Install the ROCE-related drivers, which can be verbosity drivers, based on the host's current operating system. After the driver installation is complete, install the command tool, which can be the nvmecli command, based on the host's current operating system. After the command tool installation is complete, install the multicast tool based on the current operating system. After the multicast tool installation is complete, install the multipath tool based on the current operating system.

[0167] The present invention automatically installs drivers, command tools, multicast tools, and multipath tools through the host's operating system, ensuring compatibility between the software environment and the operating system and avoiding system instability or performance degradation caused by compatibility issues. Furthermore, the present invention installs the host's software environment through the host's operating system, enabling better management and monitoring of the host's status, timely response to host changes, and ensuring the reliability and stability of host management.
