Question: Is it important that the sequence plexes/sub-disks get created in for = the primary drive and the mirrored drive be the same? Any performance = penalty?=20 I'm guessing that a different sub-disk creation order will put the = sub-disks in different places on a disk. Background - if needed: Have 10 vinum volumes being mapped by 10 plexes to the root drive. To get mirroring, I created plexes/sub-disks for swap, root, and usr = using the specific offsets for each on the 2nd hdd device and map them back to their specific volumes they should be mirroring. When I start creating the other plexes/sub-disks on the 2nd hdd and map = them back to the volume already setup, I won't be using specific offsets. Thanks, Richard
