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.

https://www.broadcom.com/support/download-search?pg=&pf=&pn=&pa=&po=&dk=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

When booting the USB DOS flash drive, boot without additional memory/drivers.

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

This tool works on HBAs.

Manual: https://docs.broadcom.com/doc/12355769

• -o enable advanced commands
• -c controller
• -f firmware
• -b BIOS
• -u backup
• -l log

Example to boot from USB DOS drive, backup and update 9207-8i HBA firmware and BIOS:

c:

cd c:\9207_8i_LSI_SAS\sas2flash_dos_rel

sas2flsh_x86.exe -ufirmware SAS9207-8i_FW-Backup.fw
sas2flsh_x86.exe -ubios SAS9207-8i_BIOS-Backup.rom

sas2flsh_x86.exe -l flashlog.txt -o -f ..\Firmware\9207_8i_LSI_SAS\Firmware\9207-8.bin -b ..\sasbios_rel\mptsas2.rom

Use Rufus to make a FreeDOS USB boot volume.

Copy:

sas2flsh.exe
2118it.bin

to the root of the USB flash drive.

Boot from the USB flash drive.

execute:

sas2flsh -listall

Note the numbers of the 2 cards (should be 0 and 1).

Execute:

sas2flsh -c 0 -o -e 6 (erases the firmware ROM, do not reboot until new firmware is loaded)
sas2flsh -c 0 -f 2118it.bin

sas2flsh -c 1 -o -e 6 (erases the firmware ROM, do not reboot until new firmware is loaded)
sas2flsh -c 1 -f 2118it.bin

sas2flsh -listall

Verify the firmware is loaded properly.

There is no need to load the mptsas2.rom unless you want to boot from a disk connected to the HBA cards (just use the SATA ports for boot, or USB).

The above is also true if you use the UEFI installer which is recommended. The command is sas2flash.efi instead. The command map lists all drives in the EFI shell. Change drives in UEFI like DOS DriveName: to change dir.
