Compatibility With Virtual Disks Created on SAS 6/iR ControllersVirtual disks created on the SAS 6/iR family of controllers can be migrated to PERC 6 and CERC 6/i. However, only virtual disks with boot volumes of the following Linux operating systems successfully boot after migration:  Red Hat® Enterprise Linux® 4Red Hat Enterprise Linux 5SUSE® Linux Enterprise Server 10 (64-bit) NOTE: The migration of virtual disks with Microsoft® Windows® operating systems is not supported.  CAUTION: Before migrating virtual disks, back up your data and ensure the firmware of both controllers is the latest revision. Also ensure you use the SAS 6 firmware version 00.25.47.00.06.22.03.00 or newer.  <ADMIN NOTE: Broken link has been removed from this post by Dell>
Hello, I just change the sas 6 IR integrated controller by the perc 6i controller (not integrated, but don't know the difference between integrated and not integrated) but now i have some trouble 1/ on each server i do that i have in the windows system log :An error was detected on device \Device\Harddisk0\DR0 during a paging operation.  2/ when i run chkdsk.exe i have :The type of the file system is RAW. CHKDSK is not available for RAW drives. 3/ i have also one server that is in "unstable" state now. i can connect to it via comand prompt (via pexec of sysinternal) but not anymore via rdp ! thanks you by advance stephane
