replace disk on rx2620 in vg00

[Ralf Buchhold]

Hello
i must replace the root-disk from the rx2620 server in a vg00 volume-group.
This is also the booting-disk.
Any idea ?
lvreduce is ok
vgreduce says: vgreduce: Physical volume "/dev/dsk/c3t2d0s2" could not be removed since some of its
physical extents are still in use.

Thanks
Ralf

Because the server is at least running 11.23, you should you

pvchange -a n ...

instead of lvreduce.

Please see the manual for all details and step-by-step instructions:

Shalom,

vgreduce -f vg00

Follow the post command instructions.

Then replace the disk and re-mirror. If you were not already mirrored you have to restore the system from an Ignite tape.

To re-mirror:
pvcreate -B /dev/rdsk/c1t0d0 #use real disk

mkboot -l /dev/rdsk/c1t0d0
mkboot -a "hpux -lq (;0)/stand/vmunix /dev/rdsk/c1t0d0 # use real disk


# mkboot -b /usr/sbin/diag/lif/updatediaglif -p ISL -p AUTO -p HPUX -p PAD -p LABEL /dev/rdsk/c?t?d?

If you are running 64-bit OS:

# mkboot -b /usr/sbin/diag/lif/updatediaglif2 -p ISL -p AUTO -p HPUX -p PAD -p LABEL /dev/rdsk/c?t?d?


vgextend /dev/vg00 /dev/dsk/c1t0d0 # same thing
lvextend -m 1 /dev/vg00/lvol1 /dev/dsk/c1t0d0

# real disk. repeat for other lvols

lvlnboot -r /dev/vg00/lvol3 # root fs /
lvlnboot -s /dev/vg00/lvol2 #swap
lvlnboot -d /dev/vg00/lvol2 #swap/dump
lvlnboot -b /dev/vg00/lvol1
lvlnboot -R
lvlnboot -v
setboot
setboot -a 52.1.0 # second disk

Please SEP, I respect you and all your knowledge and experience, but please stop posting the PA-RISC procedures to Integrity related threads - this might cause problems and confusion.

The rx2620 is an Integrity.

Sorry.

If you were able to lvreduce already then why not do the following.

Take server down. Replace bad disk. Boot from good disk with hpux -lq .

vgcfgrecover new disk into vg00.

then follow the integrity process for root volume mirroring.

Reboot one last time from the new disk as a test.
