In a specific embodiment, when the chassis manager receives the power-on abnormality notification information, it immediately initiates a discovery request to the SAS expander; wherein, the discovery request process can follow the requirements of the SES protocol.

Through the discovery request process, the enclosure manager can obtain information about all components in all enclosures, including the power-on status of each hard disk; The status is judged to realize power-down diagnosis.

In a preferred embodiment, in S1, when at least one storage hard disk has an abnormal power-on state, send power-on abnormality notification information to the chassis manager, specifically including:

The broadcast event reaches the business layer through the driver layer and the protocol layer in turn, and the chassis manager in the business layer processes the broadcast event, and obtains the attribute information of each component of each chassis by initiating a discovery request to the SAS expander.

In a preferred embodiment, before S5, the monitoring method also includes:

The S31 chassis manager obtains the chassis in-position status information of the current chassis according to the attribute information of each component;

S32 When the chassis presence status information of the current chassis is normal, the chassis manager acquires the power-on status information of each storage hard disk in the current chassis.

In a specific embodiment, before carrying out power-off diagnosis to each storage hard disk, the state of the chassis can also be detected earlier; if the chassis is in an offline state, it is not necessary to detect the power-on situation of the hard disk; the chassis presence status information of the current chassis is normal Then, check the power-on status of the hard disk.

In a preferred embodiment, before S5, the monitoring method also includes:

The S41 chassis manager obtains the state information of each power supply unit of the current chassis according to the attribute information of each component;

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

In a specific embodiment, after detecting the state of the chassis, the power supply status of the power supply unit (i.e. PSU, Power Supply Unit) in the chassis can also be continuously checked; wherein, the power supply state of the power supply unit can also be detected through the chassis manager (i.e. discovery) collected.

After checking the power supply status of all power supply units in the chassis, if the power supply unit is found to have abnormal power supply, it is not necessary to check the power-on status of the hard disk; only when the status of each power supply unit is normal, the power-on status of the hard disk is checked.

In an actual embodiment, as shown in FIG. 5, the above-mentioned monitoring method includes the following steps:

1) Connect each hard disk to the storage device. After the device is powered on, the storage system starts and runs normally.

As shown in the storage system architecture diagram in FIG. 2 . Among them, the SAS expander chip is a programmable chip, which can be set to perform a sample test every 5s, and each sample test can collect the power-on status of the hard disk in the chassis. If the hard disk is powered off for some reason, the SAS expander will update the power-on status of the hard disk in the chip's own database.

2) When an abnormal hard disk power failure 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 the interface protocol layer.

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 requirements of the SES protocol.

After the discovery process is completed, the enclosure manager can obtain information about all components in all enclosures, including the power-on status of hard disks.

4) The chassis manager judges the power-on status of each hard disk in each chassis by taking the chassis as a unit.

5) First check the state of the chassis; if the chassis is in the offline state, it is not necessary to check the power-on status of the hard disk; otherwise, proceed to the next step of detection.

6) Then check the power supply status of all power supply units in the chassis, and the power supply status of the power supply units can also be collected through the discovery process of the chassis manager. As shown in Figure 3, the chassis manager can analyze and obtain data according to the SES protocol. For details, see the Power Supply status element in the SES protocol.

When the power supply units in the chassis are abnormal, it is not necessary to check the power-on status of the hard disk; otherwise, check the next step.

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

As shown in Figure 4, after the SES protocol is analyzed, the power-on status flag (DEVICE OFF) and the in-position status flag (COMMON STATUS) of the hard disk are mainly used.

When the hard disk is in place and the DEVICE OFF bit is set to 1, it is considered that the hard disk is powered off, that is, the power-off state needs to meet: ((COMMON STATUS!=0x05)&&(DEVICE OFF=1)). At this point, record the information about the chassis where the hard disk is located and the hard disk slot where the hard disk is located.

8) Issue a power-on command (that is, a power-on command) to the above-mentioned hard disk slot in the above-mentioned chassis, and the power-on command can be issued through the SES protocol; at the same time, record the power-on frequency value; theoretically, the power-on frequency value is in It cannot exceed 5 times within 24 hours. When it exceeds 5 times, an alarm needs to be reported and displayed on the user interface, indicating that the hard disk has suffered too many power failures.

9) Start a timer, and the duration of the timer can be set according to requirements (for example, set to 2 minutes).

After the timer expires, the chassis manager actively initiates a discovery request to obtain the latest power-on status of the current hard disk after power recovery.

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, a hard disk power failure alarm needs to be reported to notify the user to replace the hard disk in time.

To sum up, in the above monitoring method, the power-on status of the hard disk is obtained by using the SAS expander, and submitted to the upper layer for analysis, and then the upper layer makes a decision and performs corresponding processing on the hard disk, so as to replace the faulty hard disk in time, so that Greatly improve the security and reliability of the storage system.
