Comment: The international scope of this list is very cool!!

The original question(s):
I have an SS5 with an external Sun 2x2GB drive unit attached, and am
getting the following error:

WARNING: /iommu@0, 10000000/sbus@0, 10001000/espdma@5, 8400000/esp@5,
8800000/sd@3, 0 (sd3):

- Is sd3 the /var partition?
- Does this disk need to be replaced, or just low-level formatted again?
- What's the best way to perform a fix?

The responses:

Answers generally covered the following:
- Check the cables and termination
- Run fsck
- Re-format the drive
- Toss the drive and replace it

Thanks to Rasana Atreya for this nifty little script to map partitions:

cd /dev/rdsk
/usr/bin/ls -l *s0 | tee /tmp/d1c |awk '{print "/usr/bin/ls -l "$11}' | \
sh | awk '{print "sd" substr($0,38,4)/8}' >/tmp/d1d
awk '{print substr($9,1,6)}' /tmp/d1c |paste - /tmp/d1d
rm /tmp/d1[cd]

The results:

This drive is one of the drives in the external enclosure, which
contains the '/' and '/var' partitions. Mail is running on the /var
partition - arghh :-( . Not having a boot CD-ROM handy (it's on
order, really!), I brought it down to single-user mode, killed mail,
sync'd a few times, crossed my fingers, and ran fsck (yes, the drive
was still mounted because I couldn't get it un-busy to unmount it).
fsck didn't help.

I've decided what I'd like to do is move this drive's entire contents
to another drive which is completely free and available and just make
that drive the new bootable drive. Watch this list for a new question!
