[Rudensky Igor]

Good day.
I am sorry, if this question for other forums, but - problem:
I have computer with OS HP-UX 10.xx and it don't full load OS. It is start the loader and write on display:
Lv_readvgdats: Could not read VGDA 2 header & trailer from disk H/W path 8/0/19/0.6.0 (error 5)
LVM:vg[0]:pvnum=0 (dev_t=0x1f006000) is POWERFAILED
Error writing VGDA [2] to disk H/W path 8/0/19/0.6.0 (error 5)
LVM:lost quorum in vg[0], too many PVs missing!
Logical volume 64,0x2 configured as SWAP
Logical volume 64,0x2 configured as DUMP
Swap device table: (Start & size given in 512-byte blocks)
entry 0 major is 64, minor is 0x2

I am understant that LVM volume in HDD is error (corrupted or other), but what do so?
Please, tell me step by step with full command line prompt what I do.
Thanks and sorry for my English

Igor,
I suspect your disk has failed (POWERFAILED).
This means not enough information can be found to boot successfully.

Perhaps somebody more experienced can detail the recovery steps.

Shalom,

definitely a dead disk. Your system will not boot because there is not a quorom in the boot volume group. A quorum requires more than half the disks of the volume group to be present.

If you have an Ignite make_tape_recovery or make_recovery tape, you can replace the disk, boot off the tape and restore your system to use.

Hello,

Did you try to boot with option -lq (with no quorum) at ISL ?

You add to reboot and when the system ask you for interacting with it in the 10 secondes hit a key, then BO PRI and when you have ISL prompt :
ISL>hpux -lq (;0)/stand/vmunix

If it's only one of the disks of the vg00 mirror which is HS you should boot. After you have to break the mirror and put a good one instead and finally rebuild the mirror.

I put an lvm_cookbook which probably is not the last version.

Regards
Pat

Hi,

Since the error in for quorum on root VG and it is not clear wheather it is mirroed or not. If it is mirrored you can by pass the quorum check by giving "hpux -lq" at ISL prompt. If the VG is mirrored the system will come up and will let you change the bad disk.

HTH,
Devender
