are you saying that at this point vinum will scan all disk busses and decide for itself that the raid exists, and reconstruct /dev/vinum?describe the procedure for unplugging the external chassis from machine A, and plugging it into machine B, and bringing up the vinum RAID without re-initialising it (i.e. preserving the data already on it).1. On machine A, stop Vinum. Depending on the hardware, you may need to shut down. 2. Remove the chassis from machine A. 3. Connect the chassis to machine B. Depending on the hardware, you may need to shut down. 4. If you haven't rebooted machine B, run camcontrol rescan on the SCSI bus to discover the new disks. 5. Run 'vinum start'.
i know you've said in a previous post that /dev/vinum "isn't important", but since it contains mount points etc, i assume it's reasonably vital... anyway, our experience when we complete the steps above was that /dev/vinum/raid1 etc. didn't exist, so we couldn't mount the volume, which is why we went on to perform the other steps i described.
cheers,
