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
5 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.
