okies
Hardware:
1 x Sun 420R
2 x A1000
2 x Diff SCSI cards
Senario:
All working fine with 420R, 1x A1000 and 1x Diff SCSI
We need to add another A1000 as it was saturating the SCSI BUS
So 8 months ago we added another Diff SCSI card and A1000 and boot -r
The new card appeared as
3. c69t5d0 <Symbios-StorEDGEA1000-0301 cyl 52473 alt 2 hd 128 sec 64>
/pci@1f,4000/scsi@2/sd@5,0
mmm ive added card before and the only time i have seen c69t5* is when we
used a 5200 on an enterprise machine.
I though no dig deal of it and just made another raid volume and everything
returned to normal.
Then yesterday we lost the battery of the new A1000. This is where the weird
stuff began
we inserted the new battery and rebooted.
when i ran the command /etc/raid/bin/raidutil -c c69t5d0 -R to reset the
battery age it said Device not found: c69t5d0
hmm.. i ran the command format

then i ran the command /etc/raid/bin/lad

titan[/etc/raid/bin]# lad
c1t5d0 1T00844921 LUNS: 0
c2t5d0 1T10514421 LUNS: 0
<snip>
hmm..
So the problem is Raidmanager thinks the SCSI Id is c2t5 but the OS sees
its as c69t5*
has anyone else seen this. im kinda worried about this now

titan[/etc/raid/bin]# raidutil -c c69t5d0 -i
