[0002] In cloud infrastructure architecture, virtualization technology is the foundation of cloud computing. Virtualization organizes computing resources into different resource pools according to various standards. Users can define different computing resource pools based on different computing resource attributes, such as high-performance computing resource pools, high-storage-capacity resource pools, transaction processing server resource pools, etc. They can also create resource pools according to their own definitions, such as database resource pools, middleware resource pools, or other specific needs. The definition mode of resource pools is flexible and convenient. Based on PowerVM virtualization technology, PowerVM resource pools consisting of one or more CDPs can be created. PowerVM resource pools typically adopt a dual-virtual I / O server architecture, which can improve the performance, availability, and maintainability of the PowerVM virtualization environment.

[0003] In practical use, due to various reasons such as software design, functionality improvement, and vulnerability patching, it is necessary to upgrade the Power virtualization resource pool. Upgrading the Power virtualization resource pool is essentially upgrading the virtual I / O server.

[0047] PowerVM is an industry-leading family of virtualization technologies offered on POWER processor-based hardware platforms. It is a new and unified brand for IBM Power System virtualization technologies (Logical Partitioning, Micro-partitioning, Hypervisor, Virtual I / O Server, APV, PowerVM Lx86, Live Partition Mobility). PowerVM's main functions include: 1. Micro-partitioning: Chip-level virtualization technology that partitions CPU resources in units of 1 / 10 of the CPU and adjusts resources in units of 1 / 100; 2. Virtual I / O Server: VIOS enables sharing of Ethernet, SCSI, and Fibre Channel disks; 3. Live Partition Mobility (LPM): LPM enables the real-time migration of a running logical partition to another physical server.

[0048] In cloud infrastructure architecture, virtualization technology is the foundation of cloud computing. Virtualization organizes computing resources into different resource pools according to various standards. Users can define different computing resource pools based on different computing resource attributes, such as high-performance computing resource pools, high-storage-capacity resource pools, transaction processing server resource pools, etc. They can also create resource pools according to their own definitions, such as database resource pools, middleware resource pools, or other specific needs. The definition mode of resource pools is flexible and convenient. Based on PowerVM virtualization technology, PowerVM resource pools consisting of one or more CDPs can be created. PowerVM resource pools typically adopt a dual-virtual I / O server architecture, which can improve the performance, availability, and maintainability of the PowerVM virtualization environment.

[0049] In practical use, due to various reasons such as software design, functionality improvement, and vulnerability patching, it is necessary to upgrade the Power virtualization resource pool. Upgrading the Power virtualization resource pool is essentially upgrading the virtual I / O servers. Currently, upgrades are generally performed according to the official upgrade implementation steps, requiring human-computer interaction and manual operation, lacking an automated process; the operation steps are complex and prone to errors; there is a real need for batch upgrades of virtual I / O servers, and manually upgrading them one by one would consume significant time and manpower costs.

[0050] This invention introduces a method and related apparatus for upgrading a virtualized resource pool. By constructing a script system, standardized upgrade steps are provided to automatically and rapidly upgrade the Power virtualized resource pool.

[0051] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0052] like Figure 1 As shown, the present invention provides a method for upgrading a virtualized resource pool, including: S100, S200, S300, S400, S500, S600, S700 and S800;

[0053] S100. Obtain a list of servers to be upgraded in the Power virtualization resource pool, wherein the server list records server information of multiple virtual IO servers to be upgraded.

[0054] Optionally, the Power virtualization resource pool may contain one or more virtual I / O servers awaiting upgrade; therefore, the entity executing this invention can obtain the corresponding server list. This invention does not limit the server information recorded for each virtual I / O server in the server list. For example, the server information mentioned in this invention may include: the virtual I / O server's IP address, hostname, CDP configuration, and HMC management configuration, etc., and this invention does not limit this information.

[0055] Optionally, the server information and the virtual I / O server can correspond one-to-one. That is, one virtual I / O server corresponds to one piece of server information, and one piece of server information can include all the above-mentioned information; this invention does not impose any limitations on this.

[0056] S200. For any of the server information, send a corresponding upgrade package to the virtual IO server corresponding to the server information;

[0057] Optionally, for any server information, i.e., for any virtual I / O server, this invention can obtain the corresponding virtual I / O server's upgrade package. It should be noted that this invention does not restrict the source or acquisition method of the upgrade package. For example, this invention can pre-download the upgrade package from the official website, copy it to an FTP server, and then distribute the corresponding upgrade package to each virtual I / O server through the FTP server. Of course, each virtual I / O server can also actively download the corresponding upgrade package from the FTP server; this invention does not restrict this.

[0058] Optionally, this invention can directly send the decompressed upgrade package to the virtual I / O server, or it can send the compressed package to the virtual I / O server first and then decompress it, thereby improving efficiency. That is, combining... Figure 1 In some optional embodiments, after S200, the method further includes: decompressing the upgrade package to a specified directory of the corresponding virtual I / O server.

[0059] Optionally, the present invention does not impose specific restrictions on the instruction directory, and the corresponding directory path can be set according to actual needs.

[0060] S300. Verify the files of the virtual IO server, wherein the files include the files in the upgrade package, the configuration file of the virtual IO server's OpenSSL link, and the installation file of the OpenSSL tool;

[0061] Optionally, concepts such as OpenSSL links and Penssl tools are well-known in the art, and this invention will not elaborate on them further; please refer to relevant descriptions in the art for details. It should be noted that this invention does not impose specific limitations on the verification process of the aforementioned files; any feasible method falls within the protection scope of this invention.

[0062] For example, combining Figure 1 In some optional embodiments, the illustrated implementation includes steps 1.1, 1.2, and 1.3.

[0063] Step 1.1: Execute the file verification command for the files in the upgrade package to verify whether the upgrade package matches the virtual I / O server;

[0064] Optionally, the upgrade package includes a file "ck_sum.bff", which can be used to verify the correctness of all files within the upgrade package. For example, taking the upgrade package VIOS2.2.6.10.tar as an example: 1. Unzip the upgrade package to " / home / backupfile / VIOS2.2.6.10"; 2. Copy the "ck_sum.bff" file to the "padmin" user directory using "cp / home / backupfile / VIOS2.2.6.10 / ck_sum.bff / home / padmin"; 3. Execute the file verification command " / home / padmin / ck_sum.bff / home / backupfile / VIOS2.2.6.10", and then observe whether the output shows "All VIOS update files verified correctly". If so, the upgrade package has passed verification; otherwise, it has failed verification.

[0065] Step 1.2: Check if the configuration file for the openssl link and the installation file for the openssl tool exist in the virtual I / O server;

[0066] Optionally, following the official steps, upgrading the virtual I / O server requires using the OpenSSL tool and creating a symbolic link "ln -s / usr / bin / openssl / usr / ios / utils / openssl". Therefore, this invention can check whether the OpenSSL configuration file and the OpenSSL tool installation file exist in the virtual I / O server.

[0067] Optionally, there is no necessary order of execution between steps 1.1 and 1.2. Step 1.1 can be executed first, or step 1.2 can be executed first, or steps 1.1 and 1.2 can be executed in parallel. This invention does not impose any restrictions on this.

[0068] Step 1.3: If the upgrade package matches the virtual IO server, and the virtual IO server contains the configuration file for the openssl link and the installation file for the openssl tool, then all the files are verified.

[0069] Optionally, if the upgrade package does not match the virtual I / O server, a matching upgrade package can be re-delivered to the virtual I / O server; if the configuration file for the openssl link exists in the virtual I / O server, relevant personnel can be reminded to configure the configuration file; if the installation file for the openssl tool does not exist, it indicates that the openssl tool is not installed, and the installation of the openssl tool can be controlled. This invention does not impose any restrictions on this.

[0070] S400. If all the files pass the verification, the SEA network card of the virtual IO server is set to standby mode.

[0071] Optionally, the SEA network interface card (NIC) is a well-known concept in the art, and this invention will not elaborate on it further; please refer to relevant descriptions in the art for details. It should be noted that, as mentioned above, this invention generally employs a dual-virtual I / O server architecture. Therefore, both virtual I / O servers have corresponding SEA NICs. When upgrading one virtual I / O server, the SEA NIC of that server needs to be set to standby mode. To avoid affecting the operation of related systems, the SEA NIC of the other virtual I / O server, which does not currently require upgrading, can also be set to active mode.

[0072] For example, initially, the production network interface card (NIC) of virtual I / O server 1 is in Primary state, while the management NIC and heartbeat NIC are in Standby state; the production NIC of virtual I / O server 2 is in Standby state, while the management NIC and heartbeat NIC are in Primary state. Before upgrading, it is necessary to switch the production NIC of the virtual I / O server 1 to be upgraded to Standby state. The switching command is: chdev-dev entxx-attr ha_mode=standby. This invention does not impose any restrictions on this.

[0073] That is, combining Figure 1 In some optional embodiments of the illustrated implementation, S400 includes:

[0074] If all the files pass the verification, the production network card in the SEA network card of the virtual IO server will be set to standby status by switching command.

[0075] S500, Check and uninstall the temporary patch for the virtual IO server;

[0076] Optionally, the upgrade package is usually a large patch set containing multiple patches. If the virtual I / O server has already upgraded some of the temporary patches in the package, these need to be uninstalled before upgrading; otherwise, the upgrade cannot be completed.

[0077] For example, combining Figure 1 In some optional embodiments of the illustrated implementation, S500 includes:

[0078] The temporary patch is checked by executing a patch check command.

[0079] Optionally, the patch checking command mentioned in this invention can be "emgr -l 2", and this invention does not limit it.

[0080] If the virtual I / O server has the temporary patch installed, then uninstall the temporary patch.

[0081] S600. Check if there are any unsubmitted installation packages in the operating system of the virtual IO server;

[0082] Optionally, taking the AIX operating system as an example, there may be installation packages in the APPLIED state that have not been committed. These packages need to be committed before the upgrade can continue. The command to check the installation package can be "lslpp -l|grep APPLIED", and the command to commit the installation package can be " / usr / ios / cli / ioscli updateios-commit". This invention does not impose any restrictions on these commands.

[0083] For example, combining Figure 1 In some optional embodiments of the illustrated implementation, S600 includes:

[0084] By executing the installation package check command, the system checks whether there are any unsubmitted installation packages in the AIX operating system of the virtual I / O server.

[0085] For example, in conjunction with the previous embodiment, in some optional embodiments, after checking whether there are unsubmitted installation packages in the AIX operating system of the virtual I / O server by executing the installation package check instruction, the method further includes:

[0086] If the AIX operating system of the virtual I / O server contains an unsubmitted installation package, the installation package is submitted by executing the corresponding installation package submission command.

[0087] S700. If the unsubmitted installation package does not exist in the operating system, then the openssl link is invoked to upgrade the patch of the virtual IO server.

[0088] Optionally, this invention can automatically upgrade patches by calling an OpenSSL link, without manual intervention, which is highly efficient. For example, executing the command " / usr / ios / cli / ioscli updateios-accept-install-dev / home / backupfile / VIOS2.2.6.10" is not a limitation of this invention.

[0089] S800. Restart the virtual IO server to complete the upgrade of the virtual IO server in the Power virtualization resource pool.

[0090] Optionally, this invention does not impose specific restrictions on the method of restarting the virtual I / O server. For example, the command " / usr / ios / cli / ioscli shutdown –restart" can be executed to restart the virtual I / O server.

[0091] Optionally, before rebooting, this invention can also modify configuration files such as ` / etc / ssh / sshd_config` to ensure root user login authorization. For example, combined with... Figure 1 In some optional embodiments, prior to S800, the method further includes:

[0092] Modify the target configuration file of the virtual I / O server, wherein the target configuration file includes at least the / etc / ssh / sshd_config file.

[0093] For example, this invention can remove the "#" at the beginning of the line "#PermitRootLogin yes" in the / etc / ssh / shd_config file and restart the sshd service or host to allow the root user to access it.

[0094] Optionally, after a reboot, the present invention can also check the system version, system services, and processes, etc. For example, by executing the command " / usr / ios / cli / ioscli ioslevel", the present invention does not impose any limitations on this.

[0095] Optionally, any virtual I / O server can be automatically upgraded through the process provided by this invention without manual intervention, which is highly efficient and accurate.
