Hi,
I have a A1000 (12x18Gb disks) connected to a U5/diff SCSI
card. It was setup as a raid 5, with 1 hot spare and I went with the
default (?) 1 big LUN setup on c1t0d0s2 of approx 170Gb
I had then created 2 slices of approx equal size on c1t0d0s6 and
c1t0d0s7. I'm assuming thats what I did as this was a long time ago
and I don't quite recall what did; but the /etc/vfstab on the system
disk seems to bear this out.
Recently the system disk on the U5 failed. It was possible to boot
it and it would come up occassionally but was definetely on its way
out. So I installed another system disk, installed Raid Manager 6.22.1 and
patch 112126-09.
Running rm6 shows me 1 LUN as above; but when I run format my
slices/partitions have gone and only s2 is show. No s6 or s7. I'd
very much like to recover the data on those 2 partitions (backups
are 2 days alas). There were standard solaris 8 UFS filesystems with
logging created on each partition.
I tried booting from the old disk; which does work sometimes and
that shows me exactly the same thing. Has the new installation
overwritten my partitioning setup and filesystems?
Is there someway I can create those slices and recover the data on
each filesystem or is there some clever A1000/RaidManager utility
that will do this for me.
Any sort of recovery hints (other than go to backups :-) gratefully
accepted. Can I get the data back from c0t0d0s2 in some way?
Thanks
Shin
