If you need to replace a failed HDD, it might be useful to enable LED blinking. Here’s how you can do this if you have LSI RAID.
At fist let’s find HDD information.
MegaCli64 -PDList -aALL | less
What you need to find is Enclosure Device ID and Slot number. Once done, run:
MegaCli64 -PdLocate -start -PhysDrv [#Enclosure:#Slot number] -a#ARRAY
As you can see you need to specify your real Enclosure Device ID and Slot number. For instance,
[root@backup ~]#MegaCli64 -PdLocate -start -PhysDrv [32:4] -a0 Adapter: 0: Device at EnclId-32 SlotId-4 -- PD Locate Start Command was successfully send to Firmware Exit Code: 0x00 [root@backup ~]#
Now support team is able to easily replace failed HDD.
