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

Introduction
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.

See also: Cisco VSM RAID Viewer

General Parameters
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>
Gather information
Controller information

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

Controller management
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
  Changes drive in state Unconfigured-Bad to Unconfigured-Good.

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: 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
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
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> /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.
