System config.: DEC VAX 8600 running ULTRIX 3.0 w/ RL02 disk for bootstrap and 
6 RA81 disks for unix filesystems.

Background: drive #3 was accidentally de-engaged (i.e. the button marked B on
the front of the drive was un-depressed). This happened when the system was up
in multi-user mode. I brought the drive down, re-depressed the B button (all
the other RA81 had B depressed), and brought the drive back up. This was done
from single-user mode with all filesystems unmounted.
	The de-engagement was discovered when any attempt to talk to the drive
caused an error (ls on the filesystem on the drive - I/O error; mount/fsck on
the drive device - No such device or address).
	Since re-engaging the drive I can talk to it via fsck.

Problem: I cannot re-mount the filesystem that was on the drive. 
I say:
# /etc/mount /dev/ra3c /mnt

System says:
ufs_mount: fs /dev/ra3c not cleaned -- please fsck
ufs_mount: /dev/ra3c on /mnt: Invalid argument

so I obediently fsck the device with "fsck /dev/rra3c" since the drive was
configured with only c partition in use for the entire space on the disk.
Fsck finds no problems and no complaints. I try to re-mount now and I get the
same error:
ufs_mount: fs /dev/ra3c not cleaned -- please fsck
ufs_mount: /dev/ra3c on /mnt: Invalid argument

Question: How can I get the system to let me mount the filesystem and get at
the info. on the drive (w/ ls, cp, mv, etc.) WITHOUT 'newfs'ing the drive?
