Adapter parameter -aN
The parameter -aN (where N is a number starting with zero or the string ALL) specifies the PERC5/i adapter ID. If you have only one controller it’s safe to use ALL instead of a specific ID, but you’re encouraged to use the ID for everything that makes changes to your RAID configuration. |
Physical drive parameter -PhysDrv [E:S]
For commands that operate on one or more pysical drives, the -PhysDrv [E:S] parameter is used, where E is the enclosure device ID in which the drive resides and S the slot number (starting with zero). You can get the enclosure device ID using “MegaCli -EncInfo -aALL”. The E:S syntax is also used for specifying the physical drives when creating a new RAID virtual drive. |
Virtual drive parameter -Lx
The parameter -Lx is used for specifying the virtual drive (where x is a number starting with zero or the string all). |

Controller management
Silence active alarm |
MegaCli -AdpSetProp AlarmSilence -aALL |
Disable alarm |
MegaCli -AdpSetProp AlarmDsbl -aALL |

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!).
Physical drive information
MegaCli -PDList -aALL |
MegaCli -PDInfo -PhysDrv [E:S] -aALL |
Blinking LED’s
Start blinking |
MegaCli pdlocate physdrv \[252:0\] a0 |
Stop blinking |
MegaCli pdlocate stop physdrv \[252:0\] a0 |
where 252 is the enclosure’s device id, find it out via:
MegaCli encinfo a0

Virtual drive information
MegaCli -LDInfo -Lall -aALL |
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)
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 |
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
