(SP16369). The firmware for the 431 should fix your issue.

Having installed the correct utils and drivers from SS5 we then set the server up with a new RAID 1 array on the new controller and left the original disk on the built in SCSI controller. We then used Nortons Ghost to transfer the data/os from the single disk to the Array. Next we removed the original disk and rebooted the server onto the RAID disks. This all went fine. The final task was to use the original disk from the SCSI bus in the array and migrate it to RAID 5. Tried to start this, but got an error mesage informing us that we needed a newer version of the firmware to support migration. We thought we had the latest (1.18a). Anyone got any Ideas please? <BR /> <BR />Kevin Wed, 08 Aug 2001 23:00:00 GMT https://community.hpe.com/t5/disk-enclosures/array-migration/m-p/2563525#M2481 Ayman Altounji 2001-08-08T23:00:00Z https://community.hpe.com/t5/disk-enclosures/array-migration/m-p/2563526#M2482 We are presently up to V1.22 (SP17866) for the Smart 431.
