First run the hpacucli command to start the utility. Once the utility is started run the command below to show your arrays and disks.
=> ctrl all show config
In my case I had added 3 additonal drives to a DL385 G1 with the intention of creating a simple raid1 mirror with a hot spare. The command below creates the second array, array B.
=>ctrl slot=0 create type=ld drives=2:3,2:4 raid=1
Now I can view my new array using ctrl all show config.
array B (Parallel SCSI, Unused Space: 0 MB)
logicaldrive 2 (67.8 GB, RAID 1, OK)
physicaldrive 2:3 (port 2:id 3 , Parallel SCSI, 72.8 GB, OK)
physicaldrive 2:4 (port 2:id 4 , Parallel SCSI, 72.8 GB, OK)
Now I add the remaining drive as a hot spare to the newly created array B
=> ctrl slot=0 array B add spares=2:5
The command below can be used to show the status of your array, which in my case is not good.
=> ctrl all show status
Smart Array 6i in Slot 0 (Embedded)
Controller Status: OK
Cache Status: Temporarily Disabled
Battery/Capacitor Status: Failed (Replace Batteries/Capacitors)
