Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0059] Embodiment one:

[0060] As shown in the figure, the present application provides a monitoring method for power-on state of storage hard disks. A plurality of storage hard disks are arranged in a plurality of cases, and the monitoring method comprises the following steps: Figure 1 S1, the SAS expander acquires power-on state information of all the storage hard disks, and sends power-on abnormality notification information to the case manager when power-on state of at least one storage hard disk is abnormal;

[0061] S2, the case manager acquires component attribute information of each case through the SAS expander; wherein, the component attribute information comprises power-on state information of each storage hard disk in each case;

[0062] S5, the case manager acquires power-off hard disk information according to the power-on state information of each storage hard disk, and sends power-on command to the corresponding power-off hard disk;

[0063] S6, the case manager acquires power-on state information of the power-off hard disk after power-on according to the predetermined time, and sends hard disk power-off alarm information to the user terminal when the power-on state information of the power-off hard disk after power-on is abnormal.

[0064] In a specific embodiment, the SAS expander is used to monitor the power-on state of each hard disk. The SAS expander can read and record the power-on state of the hard disk. When the power-on state of the hard disk is found to be abnormal, the SAS expander sends power-on abnormality notification information to the case manager.

[0065] After receiving the power-on abnormality notification information, the case manager acquires the current attributes of the case from the SAS expander, including the power-on state of each hard disk.

[0066] After the case manager acquires the power-on state of the hard disk, it determines whether there is an abnormal power-off. If there is an abnormal power-off, the faulty hard disk is re-powered.

[0067] Then, the case manager determines whether to report an alarm according to the actual power-on result of the faulty hard disk, to inform the user to replace the corresponding faulty hard disk.

[0068]

[0069] ​In summary, the SAS expander is used to monitor the power-on state in real time, the chassis manager is used to diagnose the power-off state and the power-on operation, so that the power-off hard disk can be found in time, and the user can effectively deal with the problem hard disk in time, thereby effectively ensuring the safety of the storage system and the data transmission efficiency.

[0070] In practical applications, SAS (Serial Attached SCSI) is a computer hub technology, which is mainly used for data transmission of peripheral components, such as hard disks, CD-ROMs and other devices.

[0071] The SAS expander (SAS Expander) is an expander that complies with the SAS protocol and can be used for chassis management. The downstream port of the SAS expander can be connected to a hard disk.

[0072] SES (SCSI Enclosure Services) is a standard for chassis management developed by the T10 Technical Committee.

[0073] EN (Enclosure Mangement) represents chassis management; slot represents the slot of the inserted hard disk.

[0074] In a preferred embodiment, S5 specifically includes:

[0075] S51, the chassis manager obtains the power-on state flag and the in-place state flag in the power-on state information of the current storage hard disk;

[0076] S52, when the in-place state flag is correct and the power-on state flag is normal, the chassis manager determines that the current storage hard disk is in a power-off state;

[0077] S53, the chassis manager obtains the power-off hard disk information of the current storage hard disk, and sends a power-on command to the current storage hard disk.

[0078] In a specific embodiment, the power-on state information of the current storage hard disk includes the power-on state flag (DEVICE OFF) and the in-place state flag (COMMON STATUS) of the current storage hard disk. When the hard disk is in place and the DEVICE OFF bit is set to 1, it is considered that the hard disk has a power-off, that is, the power-off state needs to meet the condition: ((COMMON STATUS! = 0x05) && (DEVICE OFF = 1)).

[0079] In a preferred embodiment, S53 specifically includes:

[0080] The chassis manager obtains chassis information and disk slot information corresponding to the current storage hard disk, and sends the power-on instruction in the power recovery instruction to the chassis and disk slot corresponding to the chassis information and disk slot information.

[0081] In specific embodiments, when the current storage hard disk meets the power-off judgment condition and power-off occurs, the chassis and the hard disk slot information where the hard disk is located are recorded.

[0082] Then, the chassis manager issues a re-power-on instruction to the hard disk slot in the chassis to perform power recovery operation. If the hard disk is powered on normally, it means that the power recovery is successful. If the hard disk is not powered on normally, an alarm of hard disk power-off needs to be reported to notify the user to replace the hard disk in time.

[0083] In a preferred embodiment, S2 specifically comprises:

[0084] S21 The chassis manager sends a discovery request to the SAS expander.

[0085] S22 The SAS expander obtains the component attribute information of each chassis through the discovery process.

[0086] In specific embodiments, when the chassis manager receives the power-on abnormality notification information, it immediately initiates a discovery request to the SAS expander. The discovery request process can comply with the SES protocol requirements.

[0087] Through the discovery request process, the chassis manager can obtain the information of all components in all chassis, including the power-on state of each hard disk. Then, the chassis manager judges the power-on state of each hard disk in each chassis, thereby realizing power-off diagnosis.

[0088] In a preferred embodiment, in S1, the power-on abnormality notification information is sent to the chassis manager when at least one storage hard disk has a power-on state abnormality, specifically comprising:

[0089] S12 When at least one storage hard disk has a power-on state abnormality, the SAS expander issues a broadcast event. The broadcast event includes a request for the chassis manager to receive data notification information.

[0090] S13 After the broadcast event passes through the driver layer, the protocol layer and reaches the service layer, the chassis manager in the service layer receives the broadcast event.

[0091] In specific embodiments, when a hard disk power-off abnormality occurs, the SAS expander immediately issues a broadcast event to request the chassis manager to receive monitoring data.

[0092] The broadcast event passes through the driver layer and the protocol layer to the service layer in turn, the broadcast event is processed by the chassis manager in the service layer, and each component attribute information of each chassis is acquired by initiating a discovery request to the SAS extender.

[0093] In a preferred embodiment, before S5, the monitoring method further comprises:

[0094] S31 The chassis manager acquires chassis in-place state information of the current chassis according to the component attribute information.

[0095] S32 When the chassis in-place state information of the current chassis is normal, the chassis manager acquires power-on state information of each storage hard disk in the current chassis.

[0096] In a specific embodiment, before the power-off diagnosis of each storage hard disk, the state of the chassis can be detected first; if the chassis is in an offline state, the power-on state detection of the hard disk is not necessary; when the chassis in-place state information of the current chassis is normal, the power-on state detection of the hard disk is performed.

[0097] In a preferred embodiment, before S5, the monitoring method further comprises:

[0098] S41 The chassis manager acquires each power supply unit state information of the current chassis according to the component attribute information.

[0099] S42 When each power supply unit state information is normal, the chassis manager acquires power-on state information of each storage hard disk in the current chassis.

[0100] In a specific embodiment, after the state of the chassis is detected, the power supply state of the power supply unit (PSU) in the chassis can be further checked; the power supply state of the power supply unit can also be acquired through the discovery process of the chassis manager.

[0101] After the power supply state of all power supply units in the chassis is checked, if the power supply unit is found to have a power supply abnormality, the power-on state detection of the hard disk is not necessary; when each power supply unit state is normal, the power-on state detection of the hard disk is performed.

[0102] In an actual embodiment, as shown in Figure 5 The above monitoring method comprises the following steps:

[0103] 1) Each hard disk is connected to the storage device, the device is powered on, and the storage system is normally started and runs.

[0104] As shown in Figure 2The SAS expander chip is a programmable chip that can be set to perform a test every 5s, and the power-on state of the hard disk in the chassis can be collected each time. If the hard disk is powered off due to some reason, the SAS expander will update the power-on state of the hard disk in its own database.

[0105] 2) When the hard disk power-off anomaly occurs, the SAS expander immediately issues a broadcast event and requests the chassis manager to receive data. The broadcast event reaches the chassis manager through the SAS driver and interface protocol layer.

[0106] 3) When the chassis manager receives the broadcast event, it immediately initiates a discovery request to the SAS expander, and the discovery process follows the SES protocol requirements.

[0107] After the discovery process is completed, the chassis manager can obtain information of all components in the chassis, including the power-on state of the hard disk.

[0108] 4) The chassis manager then judges the power-on state of each hard disk in each chassis in the chassis unit.

[0109] 5) First, detect the state of the chassis; if the chassis is in the offline state, there is no need to detect the power-on state of the hard disk; otherwise, proceed to the next step.

[0110] 6) Then, check the power supply state of all power supply units in the chassis. The power supply state of the power supply unit can also be collected through the discovery process of the chassis manager. As shown in Figure 3 , the chassis manager can obtain data according to the SES protocol analysis, which can be seen in the Power Supply status element in the SES protocol.

[0111] When all power supply units in the chassis are abnormal, there is no need to detect the power-on state of the hard disk; otherwise, proceed to the next step.

[0112] 7) Similarly, after the discovery process is completed, the data of the hard disk has also been obtained by the chassis manager.

[0113] As shown in Figure 4 , after SES protocol analysis, the power-on state flag of the hard disk (DEVICE OFF) and the in-place state flag (COMMON STATUS) are mainly used.

[0114] When the hard disk is in place and the DEVICE OFF bit is set to 1, it is considered that the hard disk has power-off, that is, the power-off state needs to meet: ((COMMON STATUS!= 0x05) && (DEVICE OFF = 1)). At this time, the chassis where the hard disk is located and the hard disk slot information are recorded.

[0115] 8) The power-on command (i.e. the power-on command) is issued to the above-mentioned hard disk slot in the above-mentioned case, and the power-on command can be issued through the SES protocol; at the same time, the power-on frequency value is recorded; in theory, this power-on frequency value cannot exceed 5 times within 24 hours, and when it exceeds 5 times, an alarm needs to be reported and displayed on the user interface, indicating that the hard disk has been powered off too many times.

[0116] 9) A timer is started, and the duration of the timer can be set according to requirements (such as 2 minutes).

[0117] After the duration of the timer arrives, the case manager initiates a discovery request to obtain the latest power-on state of the hard disk after power-on.

[0118] 10) If the hard disk is powered on normally, it means that the power-on recovery is successful. If the hard disk is not powered on normally, an alarm needs to be reported to notify the user to replace the hard disk in time.

[0119] In summary, in the above-mentioned monitoring method, the SAS expander is used to obtain the power-on state of the hard disk, which is submitted to the upper layer for analysis, and then the upper layer makes a decision to process the hard disk accordingly, so as to replace the faulty hard disk in time, thereby greatly improving the safety and reliability of the storage system.

[0120] It should be noted that although each step in the flowchart is displayed in sequence according to the arrow, these steps are not necessarily executed in the order indicated by the arrow. Unless otherwise specified in this document, there is no strict order limitation for the execution of these steps, and these steps can be executed in other orders. Moreover, at least part of the steps in the flowchart can include multiple sub-steps or multiple stages, which are not necessarily executed at the same time, but can be executed at different times, and the execution order of these sub-steps or stages is not necessarily sequential, but can be executed in rotation or alternation with at least part of other steps or sub-steps or stages of other steps.
