Hi All ,
Thanks to Bill Hassell, David Lee, John Lee and special Thanks to Mohan
Sundaram, as he really helped up to a point where application was brought
up.
To Summarize:
#strings /etc/lvmtab
o/p presented that we had only two disks , one disk primary and second one
as secondary for the Volume group which had problem.
not four as i thought earlier .
# diskinfo -v /dsk/rdsk/c0t14d0
o/p ::device busy
when the same command was run on other disk , o/p was fine.
# now tried to activate the volume group
1. vgchange -a y vg01
o/p:could not attach to the volume group physical device,device busy.
2. vgchnage -a y -g n vg01
vg01 got activated but could not synchronize the logical volumes.
#ioscan -funC disk
o/p had both the disk as "claimed"
# after this tried ,
mountall
and the application started.
/////////////Still working on the disk replacement for c0t14d0.Server is
running on one disk for VG01 volume group.
regards
Sonia.

Subject: [HPADM] volume group not found while booting
Hi Admin,
I have HPUX 10.20 loaded on D380 machine.
Due to repeated power failure at site due to some circumstance, we have a
problem in one of the volume group, vgo1 and while booting server it tells
vg01/lvol1, lvol3, lvol4, lvol5 not found.
when we do bdf , we do not find the mounted files systems on these logical
volumes of vg01.
this volume group is distributed on two primary disk and mirrored to other
two disks,
i tried giving lvdisplay -v /dev/vg0*/lvol* |grep stale , it tells
vg01/lvol1 not found.
so before going for hardware replacement, wanted to check is that both the
primary and secondary must have crashed.
can we check or try to synchronize the volume group.
pls give some idea.
regards
Sonia.
