Download the MegaCLI archive from LSI and upload it to the desired Linux server. You can't use wget any more…

8.07.10_MegaCLI_Linux.zip is the version I needed for XenServer 6.2.

http://www.lsi.com/support/Pages/download-results.aspx?keyword=megacli

Copy MegaCLI to the XenServer:

# copy the MegaCLI archive here
scp -P <ssh port> Desktop/8.07.10_MegaCLI_Linux.zip root@<xenserver name or IP>:~

Install MegaCLI on the XenServer:

unzip 8.07.10_MegaCLI_Linux.zip

rpm -Uvh MegaCli-8.07.10-1.noarch.rpm

The path to MegaCLI is not added during installation, so you need to change into the directory containing the binaries and preface commands with ./:

cd /opt/MegaRAID/MegaCli/

If you are on a 64-bit platform, you may need to use MegaCli64 instead of MegaCli

In the following examples, we assume only one controller is installed and use -a0 for “Adapter 0”. If you have multiple RAID cards, you will need to specify which card to operate on.

./MegaCli -AdpSetProp -AlarmSilence -a0

You have to escape the brackets and braces needed by some commands.

To manipulate a particular physical device, address it by enclosure and slot:

Disk info for drive on port 6:

./MegaCli -pdInfo -PhysDrv \[252:6\] -aALL

BBU Info:

./MegaCli -AdpBbuCmd -aALL

Display all information about all RAID adapter / settings:

./MegaCli -AdpAllinfo -aALL

Display information about all physical drives:

./MegaCli -PDList -aALL

Display information about all logical / virtual drives:

./MegaCli -LDinfo -LALL -aALL

Removing a drive and putting it right back onto the same RAID controller will cause the drive to marked as “Foreign”. A drive in the “Foreign” state is not usable in an array.

See the detailed section here: http://thatlinuxbox.com/blog/article.php/lsi-megaraid-megacli

Find the drive that is not “Online” which should be the newly replaced drive by showing the first few lines of output for each drive:

./MegaCli -PDList -aALL | grep --before-context=12 Firmware

./MegaCli -PDMakeGood -PhysDrv \[E:S\] -aALL

Drives (arrays) from another controller (in a “Foreign” state) can be imported and used. However, if you just want to reuse a drive, you have to clear the “Foreign” state before you can use it again:

./MegaCli -CfgForeign -Clear -a0

Make this unconfigured drive a hot spare:

./MegaCli -PDHSP -Set -PhysDrv \[E:S\] -a0

Verify RAID rebuild in progress:

./MegaCli -pdrbld -showprog -physdrv\[E:S\] -a0

or display a continuous text-gui rebuild status:

./MegaCli -pdrbld -progdsply -physdrv\[E:S\] -a0

Change the adapter rebuild rate to 60%:

./MegaCli -AdpSetProp \{RebuildRate -60\} -a0

Create a single disk (RAID 0):

./MegaCli -CfgLdAdd -r0 \[252:6\] -a0

Create a two-disk (RAID 1):

./MegaCli -CfgLdAdd -r1 \[252:6,252:7\] -a0

In some circumstances, the OS can’t see the new drive when using fdisk -l. Try forcing a SCSI bus rescan:

echo "- - -" > /sys/class/scsi_host/host0/scan

You may need to find the proper host#:

cat /sys/class/scsi_host/host0/proc_name
cat /sys/class/scsi_host/host1/proc_name
cat /sys/class/scsi_host/host2/proc_name

1. Install the MegaCLI package (per above)
2. Copy the firmware image to the directory containing MegaCLI
   • You can probably use it anywhere, but it's safer to have it on the machine being flashed
3. Flash the adapter
4. Reboot

./MegaCli -AdpFwFlash -f smc2108.rom -a0

If hou have problems with firwmare, you may be able to use MegaRec to fix the problem.

Example: I was unable to upgrade a AOC-USAS2LP-H8iR card to the latest firmware. MegaCLI kept saying the image was corrupt even though I know it was not.

I was able to flash the controller to a newer version using the 8MB .rom file, then upgrade the controller to the latest version with MegaCLI.

megarec.exe -m0flash 0 af21088m.rom

Create a CacheCade software virtual drive that functions as a secondary tier of cache:

1. Enter the LSI card's WebBIOS
2. Select Configuration Wizard
3. Select Add Configuration
4. Select CacheCade - SSD Caching Configuration
5. Select an SSD drive from the left frame and click Add To Array
6. Click Accept DG
7. Click Select Array
8. Select a Drive Group and click Accept
9. Accept the final configuration
