Turn on disk UID on an HP Smart Array Controller

I have an HP ProLiant DL580 G3 and a disk had to be replaced.

It was identified the disk to be replaced was the Physicaldrive 2:2

root@linux:~ # hpacucli ctrl all show config

Smart Array 642 in Slot 3 (sn: P92260PXQS4036)

array A (Parallel SCSI, Unused Space: 0 MB)

logicaldrive 1 (273.5 GB, RAID 5, OK)

physicaldrive 2:0 (port 2:id 0 , Parallel SCSI, 146.8 GB, OK)
physicaldrive 2:1 (port 2:id 1 , Parallel SCSI, 146.8 GB, OK)
physicaldrive 2:2 (port 2:id 2 , Parallel SCSI, 146.8 GB, OK)

To turn on the disk UID, identify the controller and physical drive location

root@linux:~ # hpacucli ctrl slot=3 pd 2:2 modify led=on

To turn off the disk UID, identify the controller and physical drive location

root@linux:~ # hpacucli ctrl slot=3 pd 2:2 modify led=off
