A disk may fail in the Security Analytics S500 appliance. The drives may be hot swapped. It is important to know which physical slot the drives belong to. All hard disks are hot swappable. This document is for the S500 internal drives only.
SA-S500-10-CM
SA-S500-20-FA
SA-S500-30-FA
SA-S500-40-FA
Any Dell systems, for the drives in the server itself.
The failed disk may be found using the lsi-show
utility as root. Then determine which slot has the failed disk. The enclosure number and slot number are under the E:S columns for each drive. The first disk in this case is listed as:

The first disk is listed as Slot 8. This drive is on the far left when looking at the front of the appliance. The second is for Slot 9. The last drive on the far right is Slot 31.

There is a utility to turn on the LED lights for an individual disk that helps to identify the drive physically. The megacli command is used to display the status of the drives and also manage them. To light the LED on the drive, run the the megacli command as root: megacli -pdlocate -start|-stop -physdrv[E:S] -a0
For the drive in the first slot, Slot 8, you would run as root megacli -pdlocate -start -physdrv[25:8] -a0
. You can light up two or three drives to more easily identify the drive. To stop the LED from blinking run megacli -pdlocate -stop -physdrv[25:8] -a0
.
Once the correct drive is located and the replacement drive has arrived, remove the failed drive using the drive lever and place the new drive in the slot and make sure it is seated all the way and that the drive lever locks in place. The RAID controller will automatically recognize the newly inserted drive and begin the rebuild process, which can take many hours to complete.
To view the rebuild status of the newly inserted drive, use the E:S values of the new drive and run this command as root: megacli -PDRbld -ShowProg -PhysDrv[E:S] -a0
If the drive in Slot 9 was the one that was replaced, the command would be megacli -PDRbld -ShowProg -PhysDrv[25:9] -a0
