• Controller information

MegaCli -AdpAllInfo -aALL
MegaCli -CfgDsply -aALL
MegaCli -adpeventlog -getevents -f lsi-events.log -a0 -nolog

• Enclosure information

MegaCli -EncInfo -aALL

MegaCli -LDInfo -Lall -aALL

• Physical drive information

MegaCli -PDList -aALL
MegaCli -PDInfo -PhysDrv [E:S] -aALL

• Battery backup information

MegaCli -AdpBbuCmd -aALL

Check Battery backup warning on boot. If this is enabled on an MSP, it will require manual intervention every time the system boots

MegaCli -AdpGetProp BatWarnDsbl -a0

Управление контроллером

• Silence active alarm

MegaCli -AdpSetProp AlarmSilence -aALL

• Disable alarm

MegaCli -AdpSetProp AlarmDsbl -aALL

• Enable alarm

MegaCli -AdpSetProp AlarmEnbl -aALL

• Disable battery backup warning on system boot

MegaCli -AdpSetProp BatWarnDsbl -a0

• Change the adapter rebuild rate to 60%:

MegaCli -AdpSetProp {RebuildRate -60} -aALL

Virtual drive management

• Create RAID 0, 1, 5 drive

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

• Create RAID 10 drive

MegaCli -CfgSpanAdd -r10 -Array0[E:S,E:S] -Array1[E:S,E:S] -aN

• Remove drive

MegaCli -CfgLdDel -Lx -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 - Drive status should be "Firmware state: Rebuild"

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

• 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: Rebuild a Drive that is marked 'Foreign' when Inserted:

• Bad to good

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

• Clear the foreign setting

MegaCli -CfgForeign -Clear -aALL

• Set global hot spare

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

• 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

Gathering Standard logs
On every instance of a hard drive problem with an MSP server, we need to run the following commands to have any information about the problem:

shell> rm –f MegaSAS.log
shell> MegaCli -adpallinfo -a0
shell> MegaCli -encinfo -a0
shell> MegaCli -ldinfo -lall -a0
shell> MegaCli -pdlist -a0
shell> MegaCli -adpeventlog -getevents -f lsi-events.log -a0 -nolog
shell> MegaCli -fwtermlog -dsply -a0 -nolog > lsi-fwterm.log
