- Create RAID 0, 1, 5 drive
MegaCli -CfgLdAdd -r(0|1|5|6) [E:S, E:S, ...] -aN

- Check the RAID initialisation progress
[root@localhost MegaCli]# ./MegaCli64 -ldinfo -Lall -aALL | grep -i init
Background Initialization: Completed 1%, Taken 14 min.
- Creating a JBOD, note, couldn't create JBOD with 9260-4i controller, had to create R0 single disks:
[root@localhost MegaCli]$ ./MegaCli64 -AdpAllinfo -aALL | grep -i jbod
Enable JBOD : No
Enable JBOD : No
[root@localhost MegaCli]$ cat create_jbod.sh
#!/bin/bash
for ((i=0; i<24; i++))
do
./MegaCli64 -CfgLdAdd -r0 [0:$i] -a0
done
[root@localhost MegaCli]$ ./create_jbod.sh
Adapter 0: Created VD 0
Adapter 0: Configured the Adapter!!
Exit Code: 0x00
.. [etc]
- Found another command to create RAID0 disks (Rather than script)
./MegaCli64 -CfgEachDskRaid0 WT NORA Direct NoCachedBadBBU -a0
Adapter 0: Created VD 0
Configured physical device at Encl-0:Slot-0.
Adapter 0: Created VD 1
Configured physical device at Encl-0:Slot-1.

Walkthrough: Change/replace a drive
- Set the drive offline, if it is not already offline due to an error
MegaCli -PDOffline -PhysDrv [E:S] -aN
- Mark the drive as missing
MegaCli -PDMarkMissing -PhysDrv [E:S] -aN
- Prepare drive for removal
MegaCli -PDPrpRmv -PhysDrv [E:S] -aN
- If you’re using hot spares then the replaced drive should become your new hot spare drive
MegaCli -PDHSP -Set -PhysDrv [E:S] -aN
- In case you’re not working with hot spares, you must re-add the new drive to your RAID virtual drive and start the rebuilding
