Hi,

What's the status when you use:

ioscan -fnCdisk

Rgds, Robin.

I guess your voulume group vg03 is not activated at boot time.
look into yout /etc/lvmrc file at the custom_vg_activation()
funtion.
If you don't find vg03 in there insert it in the following form:
/sbin/vgchange -a y -s vg03
This should actiovate vg03 at boot time.

regards
Rainer

use the ioscan to detect if the disk work fine

try to change the vg group using the vgchange -a -y /dev/vg03

and mount your filesystem after that

HI
Use
#ioscan -fnC disk to confirm the disk in question is claimed by HPUX.
If disk is ok, use vgchange -a y vg03 to activate the vg and then mount it (mountall)

Thanks

Hi,

1. Try ioscan -fnkC disk
2. Run pvdisplay on that disk pvdisplay -v /dev/dsk/...
3. vgchange -a y /dev/vg03
4. if it is mirrored then run vgsync.

Good luck

I have seen message like this but only that the physical volumes were not responding.

Find out the disks in this volume group by either looking in /etc/lvmconf or by strings /etc/lvmtab

Then do a diskinfo on the character device file to see if the disk is ok. You can use ioscan,lssf commands etc.,. This could mostly be a physical problem on the disk. If so, you need to do an export and create the volume group with new disks and restore data. If it is mirrored (I don't think it is the case), you can replace the disk and do a vgcfgrestore, remove the mirrors on the disk and recreate them (vgsync doesn't do well most of the times)
