replace mirror boot disk on ia64

[Miguel Carabano_1]

Hi team,

I Need replace primary boot disk on ia64.
# idisk -wf /tmp/partitionfile /dev/rdsk/c0t6d0

# diskinfo /dev/rdsk/c0t6d0s1 | grep size

# diskinfo /dev/rdsk/c0t6d0s3 | grep size

# efi_fsinit -d /dev/rdsk/c0t6d0s1

# mkboot -e -l /dev/rdsk/c0t6d0

# efi_ls -d /dev/rdsk/c0t6d0s1 (to check EFI)

# lifls -l /dev/rdsk/c0t6d0s2 (to check LIF)

# efi_cp -d /dev/rdsk/c0t6d0s1 -u /EFI/HPUX/AUTO /tmp/x; cat /tmp/x

# mkboot -a "boot vmunix -lq" /dev/rdsk/c2t6d0

# mkboot -a "boot vmunix -lq" /dev/rdsk/c0t6d0

# dd if=/dev/rdsk/c0t6d0s3 of=/dev/rdsk/c2t1d0s3 bs=1024k

# vgcfgrestore -n /dev/vg00 /dev/rdsk/c0t6d0s2
vgcfgrestore: Cannot restore Physical Volume "/dev/dsk/c0t6d0s2",
Detach the PV or detactivate the VG, before restoring the PV.

fail when i use vgcfgrestore... any idea??

Thanks

You need to de-activate the LVM access:

# pvchange -a n /dev/...

now replace the disk

# vgcfgrestore ...

# pvchange -a y ...


see

http://docs.hp.com/en/5991-1236/When_Good_Disks_Go_Bad.pdf

for complete steps!

Hi Torsten,

# pvchange -a N /dev/dsk/c0t6d0
pvchange: Couldn't find the volume group to which
physical volume "/dev/dsk/c0t6d0" belongs.

???

Thanks!

If you have a single path to the disk only, try "n" - not "N".

Did you vgreduce this disk???

... and use "dev/dsk/c0t6d0s2" !!!

# pvchange -a n /dev/dsk/c0t6d0s2
Warning: Detaching a physical volume reduces the availability of data
within the logical volumes residing on that disk.
Prior to detaching a physical volume or the last available path to it,
verify that there are alternate copies of the data
available on other disks in the volume group.
If necessary, use pvchange(1M) to reverse this operation.

Ok!

Now you know you did the correct steps but in a wrong order ...
