System crash: Quorum not present: (boot failing with alternate disk)

Hi,

An rp4440 is encountering system crash. The capture of the boot process is in the attached file. We have tried to boot with the alternate disk, result is the same. From the LVM maintenance mode, "ISL> hpux -lm /stand/vmunix", we are getting to the # prompt, and when running pvck,

# /sbin/pvck -y /dev/rdsk/c2t1d0
pvck: /dev/rdsk/c2t1d0: LVM checksums usable

# /sbin/pvck -y /dev/rdsk/c2t0d0
pvck: I/O error
pvck: unable to open /dev/rdsk/c2t0d0

Since,

# lvlnboot -v
lvlnboot: Volume group not activated.
Cannot display volume group "/dev/vg00".
lvlnboot: Volume group not activated.
Cannot display volume group "/dev/vg01".

Tried to
# vgchange -a y vg00
vgchange: Warning: Could't attach to the volume group physical volume "dev/dsk/c2t0d0";
I/O error
LVM: VG 64 0x000000: Quorum check failed!
vgchange: Warnging: couldn't query physical volume "/dev/dsk/c2t0d0":
The specified path does not correspond to physical volume attached to this volume group
vgchange: Warning: couldn't query all of the physical volumes.
vgchange: Couldn't activate volume group "vg00":
Quorum not present, or some physical volume(s) are missing.

Re: System crash: Quorum not present: (boot failing with alternate disk)

Sir,

HPUX at the disk partitioning approach maintains a quorum resriction. One is running quorum and the other is activation quorum. Your system will not boot if less than 51% of the disks are available and in this case this is probably your problem. This is why when we mirror the boot disk hpux-lq is also given as a string with the mkboot -a command. On the ISL prompt> hpux -lq will do or if your kernel is corrupt as well. This might also help ISL> hpux -lq /stand/backup/vmunix. If it helps, do assign points. :)

Hi,

As Ismail rightly said, the Alt kernal has not been used in the lvm maintanence mode:

isl> hpux -lq /stand/backup/vmunix

All the best

Re: System crash: Quorum not present: (boot failing with alternate disk)

try maintaince mode

ISL> hpux -lm boot /stand/vmunix

then do
vgchange -q n -a y vg00

and then post the output of the errors you get.
