Disclaimer :- Debian Wheezy OS is not officially supported on Dell PowerEdge 13th Generation Server.

This wiki is written by Tamilarasan J from Dell Customs Solutions Engineering and this talks about installing a custom Perc Driver to install the wheezy OS in PowerEdge R630.

Debian Wheezy is not supported in Dell 13G servers as there is no driver available in the OS for the Perc H330. Customers running the applications in the Wheezy OS when they upgrade the server hardware from 12G to 13G i.e., PowerdEdge R630, the Perc driver throws an error while examining the storage devices as there is no driver with the Wheezy OS. The mega raid should be an updated one to have the storage devices discovered.

The Jessie OS which is recent than the Wheezy has the updated megaraid version compared to the Wheezy. There is NO Dell Official support for this process and should be at your own risk.

Please contact your Sales/Account Team for the custom PERC drivers. Perform the below operations when you have OS mounted in the server via iDrac Virtual Media or via CD/DVD Drive

When you try installing the OS, we find the similar screen after the language selection as there is no driver available for the Perc H330.

Installing the MegaRAID Driver on Storage Managed by a MegaRAID Controller during installation.

1. Copy the drivers (megaraid-xx.tgz) to a USB flash and have it plugged in the server.

2. Boot from the Debian installation CD1 and select Install.

3. Press Ctrl + Alt + F2 to switch to console2 when the language screen appears.

NOTE: The system should detect the USB flash as scsi device /dev/sda1. To check for SCSI devices, type the following command and press Enter: dmesg | grep sd

4. Type the following commands and then press Enter.

      # mkdir /mnt2 /lsi

     # mount -t vfat /dev/sda1 /mnt2

     # cp /mnt2/megaraid-6.18-deb6-3.2.0.tgz /lsi

     # cd /lsi ; tar zxvf megaraid*

     # umount /mnt2

     # insmod wheezy/lib/modules/3.2.0-4-amd64/weak-updates/megaraid/megaraid_sas.ko

NOTE Make sure that you remove the USB flash drive before you execute the insmod command.

5. Press Ctrl+Alt+F1 to return to the installer, and continue the normal installation procedure. Do not reboot after the installation is complete.

6. Press Ctrl+Alt+F2 to switch to console 2 again.

7. Type the following commands and then press Enter:

 # cp wheezy/lib/modules/3.2.0-4-amd64/weak-updates/megaraid/megaraid_sas.ko o /target/lib/modules/2.6.32-5- amd64/kernel/drivers/scsi/megaraid
