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 (or back to good as I like to call it)

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

This changes drive in state Unconfigured-Bad to Unconfigured-Good.

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

Change/replace the drive

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

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