How to locate a physical disk in an LSI raid array
The MegaCli command line utility can be used to locate a physical disk in an LSI raid array by blinking the disks activity LED. The blinking will continue until directed to stop.
Syntax: MegaCli64 -PdLocate <-start|-stop> -physdrv[<enclosure#>:<disk#>] -a<adapter#>
In this example we will locate disk 0 on adapter 0:
[root@localhost MegaCli]# ./MegaCli64 -PdLocate -start -physdrv[252:0] -a0
Adapter: 0: Device at EnclId-252 SlotId-0 — PD Locate Start Command was successfully sent to Firmware
Exit Code: 0x00
