Summary of responses:
I was pleased to discover two things: My suspicion that /dev/dsk/c0t1d0s7 is
the *target* and not the *source* for the data movement was correct.
Secondly, even some seasoned pros agreed with me that the procedure, as
stated, is a bit vague (and therefore dangerous!). I offer this revised
version:
====================START==============
Assumptions:
a) disk slice /dev/dsk/c0t0d0s3 contains a ufs mounted at /var
b) we want to move it to a larger slice, /dev/dsk/c0t1d0s3
Procedure:
Step 1: Make a new filesystem at the target location (/dev/dsk/c0t1d0s3).
format...
partition...
newfs...
Step 2: Boot into single-user mode.
Step 3: Mount the destination slice ('mount /dev/dsk/c0t1d0s3 /mnt')
Step 4: Copy source to destination:
Step 4A: 'cd /mnt'
Step 4B: 'ufsdump 0f - /var | ufsrestore rf -'
Step 5: vi /etc/vfstab (to reflect /var's new slice-location)
Step 6: reboot the server
====================END==============
