The NVME hard disk is installed on the server, the server is usually in a machine room, and workers cannot touch the server at ordinary times, if sudden conditions such as hard disk damage and sudden reduction of the hard disk performance are met, the server may need to find the hard disk in the machine room for replacement. The staff directly goes to the server to look for the hard disk that may be found by mistake, leads to changing the wrong hard disk, causes bigger influence. At this time, the NVME hard disk which has the problem under the system can be lighted up, and the worker can correctly replace the hard disk by observing the lighting-up state of the abnormal hard disk.
The NVME hard disk state indicator lamp is usually arranged on a hard disk backboard, the state of the indicator lamp represents what state the NVME hard disk is currently in, and the NVME hard disk state indicator lamp generally has several states of locate (blue lamp), rebuild (pink lamp), failure (red lamp) and normal (extinguished).
In the prior art, an led command is usually used to light an indicator lamp on an NVME hard disk, and several states of locate, failure, rebuild, and off may be set for a hard disk status indicator lamp, for example, when the locate lamp of a first NVME hard disk is lit, the command led locate =/dev/NVME0n1 is used. The command is executed without any return information, and when a plurality of hard disks need to be tested, the lighting state of the hard disks needs to be checked repeatedly, and whether the slot position indicator lamp corresponding to the current hard disk is lighted or not is confirmed.
When the ledctl is used for testing a plurality of hard disks, because the command does not return information, the hard disks which are lighted up during operation need to be recorded, and the lighting state of the hard disks is recorded, so that the recording is more troublesome when the plurality of hard disks are tested. In the development stage of the machine, because the lighting function of the hard disk backboard is incomplete, the indicator lamps between the hard disks may influence each other, for example, the indicator lamp of the first hard disk is turned on, when the second hard disk is turned on, the indicator lamp of the first hard disk is automatically turned off, and the change of the indicator lamp on the hard disk backboard is sometimes difficult to find by using the led command.
