In an embodiment, after detecting the chassis status, the Power Supply status of the Power Supply Unit (i.e., PSU) in the chassis may be continuously checked; the power supply state of the power supply unit may also be acquired through a discovery process (i.e., discovery) of the chassis manager.
After the power supply state of all the power supply units in the case is checked, if the power supply units are found to be abnormal, the hard disk does not need to be electrified; when the states of all the power supply units are normal, the hard disk is subjected to power-on condition inspection.
In a practical embodiment, as shown in fig. 5, the monitoring method includes the following steps:
1) And (4) accessing each hard disk into the storage equipment, and after the equipment is powered on, normally starting and operating the storage system.
As shown in the memory system architecture diagram of fig. 2. The SAS expander chip is a programmable chip, and can be set to conduct sampling every 5s, and the power-on state of a hard disk in a case can be acquired through sampling every time. If the hard disk is powered off due to some reason, the SAS expander updates the power-on state of the hard disk in the database of the chip.
2) When the power failure of the hard disk is abnormal, the SAS expander immediately issues a broadcast event and requests the case manager to receive data. Broadcast events reach the chassis manager via the SAS driver and interface protocol layers.
3) When the case manager receives the broadcast event, the case manager 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 chassis manager can take the information of all the components in all the chassis, including the power-on state of the hard disk.
4) And the case manager judges the power-on state of each hard disk in each case by taking the case as a unit.
5) Firstly, detecting the state of a case; if the case is in the offline state, the hard disk does not need to be subjected to power-on condition detection; otherwise, carrying out the next detection.
6) And then, checking the power supply state of all the power supply units in the case, wherein the power supply state of the power supply units can also be acquired through the discovery process of the case manager. As shown in FIG. 3, the case manager can parse the received data according to the SES protocol, which can be seen in the Power Supply status element of the SES protocol.
When the power supply units in the machine frame supply power abnormally, the hard disk does not need to be electrified for detection; otherwise, carrying out the next detection.
7) Similarly, after the discovery process is completed, the data of the hard disk is also already taken by the chassis manager.
As shown in fig. 4, after the SES protocol is resolved, the power-on STATUS flag (DEVICE OFF) and the on-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 has a power failure, that is, the power failure state needs to be satisfied: ((COMMON STATUS | =0x 05) & (DEVICE OFF = 1)). At the moment, the information of the case where the hard disk is located and the slot position where the hard disk is inserted is recorded.
8) Issuing a power-on instruction (namely a power-on instruction) to the slot position of the inserted hard disk in the chassis, wherein the power-on instruction can be issued through an SES protocol; meanwhile, recording a complex electricity frequency value; theoretically, the complex power frequency value cannot exceed 5 times within 24h, and an alarm needs to be reported and displayed on a user interface when the complex power frequency value exceeds 5 times, so that the hard disk is powered down for too many times.
9) A timer is started, and the duration of the timer can be set according to requirements (for example, set to 2 min).
After the time length of the timer is up, the chassis manager initiatively initiates a discovery request to obtain the latest power-on state after the current hard disk is powered on again.
10 If the hard disk is normally powered on, the power-on recovery is successful. If the hard disk is not normally powered on, an alarm of power failure of the hard disk needs to be reported for informing a user of timely replacing the hard disk.
In summary, in the monitoring method, the SAS expander is used to acquire the power-on state of the hard disk, and the power-on state is submitted to the upper layer for analysis, and then the upper layer makes a decision to perform corresponding processing on the hard disk so as to replace the failed hard disk in time, thereby greatly improving the safety and reliability of the storage system.
