Re: Couldn't access the list of physical volumes for volume group "/dev/test".

Is this one of the disks in question?

>> uatdata2#pvcreate -f /dev/rdsk/c2t0d2

In this case you just deleted it.

Hope this helps!

Torsten.

Re: Couldn't access the list of physical volumes for volume group "/dev/test".

Why pvcreate???

You wiped the disk!


You may try to restore the LVM information with vgcfgrestore on node1, but this information is wiped too if you used vgexport without "p" for preview.

Re-create the VG and restore the data from backup.

 

 

In case of doubt, first ask, then do.


Hope this helps!
Regards
Torsten.

Re: Couldn't access the list of physical volumes for volume group "/dev/test".

Hello, i have the next problem:

i migrated the san disks of hpux 11.31 server to a vm running hpux 11.31 too. But when i execute the vgimport command on the vm for activate the volume groups i receive the next messages:

vgimport -p -s -v -m /sort/MAPAS/vguspv2softempfian2.map /dev/vguspv2softempfian2



Beginning the import process on Volume Group "/dev/vguspv2softempfian2".

Couldn't access the list of physical volumes for volume group "/dev/vguspv2softempfian2".

when i checked the disks status, i saw the next:

a) running the "ioscan" command:

How can fix this issue ??
