The restriction is that it must be RAID-1. One note of warning is that LDEV 1 should not exceed 4 GB. If LDEV 1 has more than 4 GB, anything over is lost. ----------------------------------------------------------------------- It is true that LDEV 1 can be a disk array, however it does not need to be RAID-1. We have a C2252HA HP-FL disc as LDEV 1. It is a RAID-3 device, similar to RAID-5 that is available on the current NIKE drives. Also, the 4GB limit applies to NIO systems. CIO systems have a maximum of 2.7GB on LDEV 1. Mike Berkowitz Guess? Inc.
