I'm having some problems replacing a faulty boot disk on V5.0a.
I'm running an 8400 with the two BA shelves at the front of the cab
connected to KZPBA controllers on the PCI bus at the back, with 6 9Gb
fast-wide disks in each shelf.
The top 4 disks in each shelf are LSM mirrored, the top pair being root, the
next swap, then /usr then /var. the disks up to now have been named
/dev/disk/dsk0-5 (left shelf), /dev/disk/dsk6-11 right shelf. dsk0 and dsk6
make the root volume.
This morning dsk0 failed, this being the boot disk. The system carried on
regardless as expected, on dsk6. Once I got some downtime arranged, I was
able to replace dsk0 with a new disk and reboot directly into dsk6. No
problem.
The replacement disk came in as /dev/disk/dsk20 - the next available number.
I then followed the instructions in the LSM manual and deleted the dsk0
references, using volplex rm dis, voldg rmdisk, and voldisk rm commands as
prescribed.
I then tried to rename the new disk back to dsk0 using dsfmgr -m dsk20 dsk0
and got:
dsfmgr: ERROR: second device status is active: dsk0a
volprint -ht and voldisk list both show no remaining references to dsk0 in
any form I can recognise. Obviously this is the old root partition and
something is stuck to it somewhere. I don't want to mirror dsk20 with dsk6,
and anyway I suspect something will fail later if this isn't resolved.
I've tried a reboot but this didn't produce any chang.
Does anyone have any idea what I can do to clear this up.
TIA
