Compatibility With Virtual Disks Created on SAS 6/iR Controllers

The migration of virtual disks created on the SAS 6/iR family of controllers
can be migrated to PERC 6 and CERC 6i. However, only virtual disks with
boot volumes of the following Linux operating systems successfully boot after
migration:

Red Hat Enterprise Linux 4 Update 5

Red Hat Enterprise Linux 5

SUSE Linux Enterprise Server 10 (64-bit)

NOTE:

The migration of virtual disks with Microsoft Windows operating systems is

not supported.

NOTICE:

Before migrating virtual disks, back up your data and ensure that the

firmware of both controllers is the latest revision. Also ensure that you use the
SAS 6 firmware version 00.25.41.00.06.22.01.00 or later version.

Migrating Virtual Disks from SAS 6/iR to PERC 6 and CERC 6i

NOTE:

The supported operating systems listed above contain a driver for the

PERC 6 and CERC 6i controller family. No additional drivers are needed during the
migration process.

1 If virtual disks with one of the supported Linux operating systems listed

above 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 6i. If you are replacing your SAS 6/iR controller with a
PERC 6, see the Hardware Owner’s Manual that came with your system.

CAUTION:

After you have imported the foreign configuration on the PERC 6 or

CERC 6i storage controllers, you cannot migrate the storage disks back to the SAS
6/iR controller as it may result in the loss of data.
