SAS 5/iR does not allow for RAID Level Migration or Capacity Expansion (Reconfiguration in OMSA parlance).

Such conversion would be very risky, to say the least. (In RAID1, you have a copy of each data block on both disks, in RAID0, you distribute data blocks evenly: block0 -> disk0, block1 -> disk1, block2 -> disk0, block3 -> disk1 etc.) Apart from that, the SAS 5/iR is a rather stupid controller with no fancy logic etc, so I guess it's simply not supported. > >From the lack of that option in VD menu I assume that is the case, > unless it's matter of a driver version: > > Firmware Version 00.10.51.00.06.12.05.00 > Driver Version 3.04.03 > Minimum Required Driver Version 3.12.29.00 > > This is OM 6.2 on Fedora 6 (cannot be upgraded to suit unfortunately). OMSA or OS version shouldn't matter at all.
