Migrating Virtual Disks from SAS 6/iR to PERC 6 and CERC 6/i
NOTE:
The supported operating systems listed in "Compatibility With Virtual Disks
Created on SAS 6/iR Controllers" on page 28 contain the driver for the PERC 6
and CERC 6/i controller family. No additional drivers are needed during the
migration process.
1
If virtual disks with one of the supported Linux operating systems listed in
"Compatibility With Virtual Disks Created on SAS 6/iR Controllers" on
page 28 are being migrated, open a command prompt and type the
following commands:
modprobe megaraid_sas
mkinitrd -f --preload megaraid_sas /boot/initrd-
`uname -r`.img `uname -r`
2
Turn off the system.
3
Move the appropriate physical disks from the SAS 6/iR controller to the
PERC 6 and CERC 6/i. If you are replacing your SAS 6/iR controller with a
PERC 6 controller, see the
Hardware Owner’s Manual
shipped with your
system or on the Dell Support website at support.dell.com .
CAUTION:
After you have imported the foreign configuration on the PERC 6 or
CERC 6/i storage controllers, migrating the storage disks back to the SAS 6/iR
controller may result in the loss of data.
4
Boot the system and import the foreign configuration that is detected.
You can do this in two ways:
•
Press <F> to automatically import the foreign configuration
• Enter the BIOS Configuration Utility and navigate to the Foreign
Configuration View
NOTE:
For more information on accessing the BIOS Configuration Utility ,
see "Entering the BIOS Configuration Utility" on page 79
.
NOTE:
For more information on Foreign Configuration View, see "Foreign
Configuration View" on page 104

If the migrated virtual disk is the boot volume, ensure that the virtual disk
is selected as the bootable volume for the target PERC 6 and CERC 6/i
controller. See "Controller Management Actions" on page 104.
