Hey all you DG/UX guys out there: I have a question regarding logical disk partitions under DG/UX 4.2. We have a 300MB scsi drive on an AViiON 300 series workstation. We want to split this drive onto two new drives, with the ROOT and USR logical drives on a 179MB scsi drive, and the user data on a 600MB scsi drive. The problem is this: we want to create a new logical drive on the 179MB drive, with the same logical drive name, viz ROOT. But this creates problems. Whan the system boots, it seems to look at all the scsi drives, and complains about not being able to find a non-existent part number 0 on the scsi drive. Subsequent mounts in the rc scripts fail until the second drive is unregistered. It is then impossible to do anything with the drive, because there does not seem to be any way to refer to it, even though, physically, the real boot drive is sd(insc(),0)ROOT: and the other one is sd(insc(),1)ROOT:. We can't copy the logical partition (which may be different sizes anyway), and the only option seems to be to use tapes. Assuming we do this, how do we overwrite the root disk, since diskman and its utilities will be running from the disks that we are overwriting?!! Is there an easy way around this, or am I missing something obvious? Although names partitions are a nice idea, they seem to cause problems when you want to use the same name twice. Now, if there way a utility to RENAME a logical partition, we'd be fine.... Help! Richard Brown
