Default Weird missing disk fsck boot problem

Hello,

I have a server which we use for NFS, SMB, and CVS. It is an E250
connected to an external A1000 RAID box. The setup has been VERY
reliable for the last 7 or so years. I have to say that this has been
en exceptionally stable platform.

The internal disks are mirrored for failover and the external RAID box
houses the cvs depot, nfs and smb shares.... I use soft partitions
for the filesystems (Solaris Volume Manager). I simply grow a soft
partition and the particular filesystem when I need to.

It seems to me that volume manager is referencing c2 while the RAID
array is now, for some reason, c3. Perhaps the battery change did
this? I didn't. If so it still doesn't explain why it manifested
AFTER the OS patches and not merely AFTER the controller battery
change or drive change...... That one has me scratching my head.


Background:

2 weeks ago I replaced the controller battery in the RAID array, as
well as an internal failed disk in the RAID array device. It uses one
disk as a hot spare, and when I replaced the faulty disk with a new
one it did what it does and all was/is well with that. (or so I
thought?)

This weekend I patched the machine with the latest 9_Recommended in
order to get it up to date and to get the DST patch. The patch bundle
overwrote my inetd.conf, but I think I fixed that okay and now my CVS
server and SWAT once again start up on boot.

The problem is that for every boot, the boot process is paused for
what the system says is a missing disk device. This is odd b/c it
wasn't happening prior to the 9_Recommended patch and once the machine
is up everything looks fine and all of the expected filesystems are
present and mounted. Nothing that it is searching for is on the
vfstab.

The /var/adm/messages file complains about this:

Mar 11 17:40:53 localhostname fsck: [ID 309067 daemon.error]
localhostname: /dev/rdsk/c2t10d0s6: No such device or address

????

.....and in the device.tab this is referenced but again I can't
remember why it would be there and all of the expected partitions are
there.

disk9:/dev/rdsk/c2t10d0s2:/dev/dsk/c2t10d0s2::desc="Disk Drive"
type="disk" part="true" removable="false" capacity="212381696"
dpartlist="dpart900,dpart906"

An observation which may or may not be pertinent, (I think it is) is
that the RAID array controller calls itself disk, c3t10d0s2, which
except for one number is very close to the c2t10d0s2 that the system
is complaining about. Perhaps it changed it's name when I replaced
the controller battery? What discourages me from that notion is that
if that were so then this boot behavior should have manifested 2 weeks
ago, not just after this weekend's patch install. ??

These are my disks in format:

AVAILABLE DISK SELECTIONS:
0. c0t0d0 <SUN36G cyl 24620 alt 2 hd 27 sec 107>

As you can see, s6 is where I keep my important data:

Current partition table (original):
Total disk cylinders available: 65533 + 2 (reserved cylinders)


Part Tag Flag Cylinders Size Blocks
0 root wm 0 0
(0/0/0) 0
1 unassigned wm 0 0
(0/0/0) 0
2 backup wu 0 - 65532 337.98GB (65533/0/0)

3 unassigned wm 0 0

4 unassigned wm 0 0

5 unassigned wm 0 0

7 unassigned wm 65532 - 65532 5.28MB (1/0/0)
10816

========

metastat shows this:

# metastat |grep c2t10d0

Device: c2t10d0s6
c2t10d0s6 10816 No Yes
Device: c2t10d0s6
c2t10d0s6 10816 No Yes
c2t10d0 Yes id1,iver@w600a0b80000a5ed90000000f3d94158d


grepping c3 shows nothing........

=================

So, could I ask for advice on how to eliminate this because every time
the machine reboots fsck pauses the bot process for operator
assistance, either enter the root passwd for maintenance or CRTL-D to
continue. So, if no one is present and the machine were rebooted, or
rebooted remotely, it wouldn't come up without operator assistance at
the console and this machine is not hooked to anything like a
networked console server device.

I figure that I have to change/update the volume manager to use c3
instead of c2, but I wanted to run that by some pros and perhaps its
not that easy. Right now all of my filesystems are there and I didn't
want to change such a thing willy nilly without checking.

I set all of this stuff up several years back and am a bit rusty, so
hence my question to the groups. Better to consult first than to do
it without realizing the ramifications and make a fatal error. ;-)




Thank You for taking the time,

Tom
