Problem analysis:
The storage data disk is damaged, smartctl cannot recognize it, and it cannot be mounted. How to locate the location of the data disk for disk replacement

Problem handling process:

1. Check the raid card model.

lspci |grep -i raid

2. Get the “location information” and “identity information” of all healthy hard disks that the RAID card can identify

/opt/sds/diskled/MegaCli64 -PDList -aAll | grep -Ei "Enclosure Device ID|Slot Number|Inquiry Data“

3.Use SMART tool to check the Serial number of the hard disk

smartctl -i /dev/sdc |grep -i 'Serial number’

4. Use the exclusion method to obtain the Enclosure Device ID and Slot Number information of the hard disk that cannot be viewed

5. Physically locate the failed hard drive by causing its light to start blinking.

/opt/sds/diskled/MegaCli64 -PDLocate -Start -PhysDrv [32:7] -a0
