couldn't uery Physical volume /dev/dsk/c1t0d0s2

[Syedfurquan]

Hi ,

I am getting an error in vgdisplay -v vg00 op that couldn't query physical volume. Then I check diskinfo it is showing disk size as o bits. I identify teh disk using dd if=/dev/dsk/c1t0d0 of=/dev/null bs=4k and then did

# pvchange -a n /de/dsk/c1t0d0s2 then replace the disk. After replcaing the server got hanged and nothing is coming. Again reinsert the same old disk by removing new one and server started working but still getting same error.

Same error in lvlnboot -v also.

It is rx 2660 with HP-UX 11.23

Anyhelp will be very much appreciated.

It looks like the disk you replaced could be a boot disk.  Are the LV's on that disk mirrored to another, c1t1d0_s2 perhaps?

Please attach the output of "vgdisplay -v vg00", "lvlnboot -v" and the "/var/adm/syslog/syslog.log" file.

Hi,

I have solve that problem.

I try to do:-

vgreduce -f vg00

mv /etc/lvmtab /etc/lvmtab.old

vgscan

It worked.

Then pvcreate on the new hdds and then mirror it.
