• 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.

• Clear all foreign drives

MegaCli -CfgForeign -Clear -aN

Physical drive management

• Set state to offline

     MegaCli -PDOffline -PhysDrv [E:S] -aN

• Set state to online

     MegaCli -PDOnline -PhysDrv [E:S] -aN

• Mark as missing

     MegaCli -PDMarkMissing -PhysDrv [E:S] -aN

• Prepare for removal

     MegaCli -PdPrpRmv -PhysDrv [E:S] -aN

• Replace missing drive

     MegaCli -PdReplaceMissing -PhysDrv [E:S] -ArrayN -rowN -aN
     The number N of the array parameter is the Span Reference you get using „MegaCli -CfgDsply
     -aALL“ and the number N of the row parameter is the Physical Disk in that span or array
     starting with zero (it’s not the physical disk’s slot!).

• Rebuild drive

     MegaCli -PDRbld -Start -PhysDrv [E:S] -aN
     MegaCli -PDRbld -Stop -PhysDrv [E:S] -aN
     MegaCli -PDRbld -ShowProg -PhysDrv [E:S] -aN

• Clear drive

     MegaCli -PDClear -Start -PhysDrv [E:S] -aN
     MegaCli -PDClear -Stop -PhysDrv [E:S] -aN
     MegaCli -PDClear -ShowProg -PhysDrv [E:S] -aN

• Bad to good

     MegaCli -PDMakeGood -PhysDrv[E:S] -aN
     Changes drive in state Unconfigured-Bad to Unconfigured-Good. 

• Drives appear as FOREIGN (either part of old/other raid pack)

     MegaCli64 -CfgForeign -Scan -Clear

Hot spare management

• Set global hot spare

     MegaCli -PDHSP -Set -PhysDrv [E:S] -aN

• Remove hot spare

     MegaCli -PDHSP -Rmv -PhysDrv [E:S] -aN

• Set dedicated hot spare

     MegaCli -PDHSP -Set -Dedicated -ArrayN,M,... -PhysDrv [E:S] -aN 

Walkthrough: Change/replace a drive

  1. Set the drive offline, if it is not already offline due to an error
     MegaCli -PDOffline -PhysDrv [E:S] -aN

  2. Mark the drive as missing
     MegaCli -PDMarkMissing -PhysDrv [E:S] -aN

  3. Prepare drive for removal
     MegaCli -PDPrpRmv -PhysDrv [E:S] -aN

  4. Change/replace the drive

  5. If you’re using hot spares then the replaced drive should become your new hot spare drive
     MegaCli -PDHSP -Set -PhysDrv [E:S] -aN

  6. 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

     MegaCli -PdReplaceMissing -PhysDrv [E:S] -ArrayN -rowN -aN
     MegaCli -PDRbld -Start -PhysDrv [E:S] -aN
