MegaCli commands have presented a number of questions among our users for Cisco's Physical Security. Here is an attempt to explain thier meaning and uses.
LD称之为Logical Device
VD(虚拟硬盘)
- Virtual Drive (VD)：虚拟硬盘，简单说就是Raid
- VD State Optimal : Raid目前为正常
- VD State Degraded : Raid状态不正常，退化或者降级
PD(物理硬盘)
- Physical Drive (PD)：实体硬盘，实际有的硬盘数量
- PD State Online : 硬盘目前的状态为正常
- PD State Fail、Unconfigured、Rebuld：磁盘状态不正常，掉盘、未配置或正在重建Raid
- -a 是raid卡
- -LD 表示Virtual Disk
- -PD Physical Disk
Adapter parameter -aN
The parameter -aN (where N is a number starting with zero or the string ALL) specifies the 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 (see 5).
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).
Running the executable can be accomplished by:
shell> /opt/MegaRAID/MegaCli/MegaCli <cmd>
or
shell> cd /opt/MegaRAID/MegaCli
shell> ./MegaCli <cmd>
Controller information
MegaCli -AdpAllInfo -aALL
MegaCli -CfgDsply -aALL
MegaCli -adpeventlog -getevents -f lsi-events.log -a0 -nolog
Enclosure information
MegaCli -EncInfo -aALL
Virtual drive information
MegaCli -LDInfo -Lall -aALL
Physical drive information
MegaCli -PDList -aALL
MegaCli -PDInfo -PhysDrv [E:S] -aALL
Battery backup information (Cisco MSPs do not have the battery backup unit installed, but in case yours has one)
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
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
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
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
Changes drive in state Unconfigured-Bad to Unconfigured-Good.
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
-
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
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
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> /opt/MegaRAID/MegaCli/MegaCli -adpallinfo -a0
shell> /opt/MegaRAID/MegaCli/MegaCli -encinfo -a0
shell> /opt/MegaRAID/MegaCli/MegaCli -ldinfo -lall -a0
shell> /opt/MegaRAID/MegaCli/MegaCli -pdlist -a0
shell> /opt/MegaRAID/MegaCli/MegaCli -adpeventlog -getevents -f lsi-events.log -a0 -nolog
shell> /opt/MegaRAID/MegaCli/MegaCli -fwtermlog -dsply -a0 -nolog > lsi-fwterm.log
Collect the MegaSAS.log, lsi-events.log, and the lsi-fwterm.log files from the directory where the commands are run (they can be run from any directory on the MSP server) and attach the logs to the service request. You may use a program such as WinSCP (freeware) to pull the files off of the server.
