Date: Sun 09-Aug-1989 21:42:04 From: Unknown Subject: rdump, disappearing SCSI drives Am I missing something in the usage of rdump on The Cube? I am trying to rdump the SCSI drive to a Sun 3/160 running Sun OS 3.5. The tape drive in question is a Cipher M990 (might have the model number wrong) We are at software release 0.9. The command I am using is the following: /etc/rdump 0udf 6250 julius:/dev/rmt8 /dev/rsd0a Any suggestions greatly appreciated. We've had two cubes for about a month, and I've already had to rebuild SCSI drives three times and an optical disk once. I've rebuilt the SCSI drives because I find the cubes begging for someone to 'Insert the Disk'. When I boot the system with the optical drive, I am unable to mount the SCSI drive. The error message I get is '/dev/sd0a: not found'. (/dev/sd0a exists in the file system, but the cube doesn't recognize that the hardware exists, I think) Dale Wyttenbach | ...rutgers!umn-cs!wytten wytten@umn-cs.cs.umn.edu | wytten@umnacvx.bitnet Computer Science Department Systems Staff--University of Minnesota, Minneapolis >From: ali@polya.Stanford.EDU (Ali T.

When you do get the "Insert the Disk," get to the "NeXT>" prompt (with a CMD-tilde) and try to boot from the SCSI with "bsd". If that fails, then your SCSI might be trashed or maybe it's the cables aren't connected very well. If "bsd" does the trick then you should set the default boot device to be SCSI so you don't get the "Insert the Disk" prompt anymore.
