I/O error while reading the VGDA

[Manel Ventura]

Hello,

I'm installing two new machines (Production and Integration environments) that will have the same volume groups that we alredy have defined in the Development environment.

To create the volume groups in the new machines, I've done the following:

Development:
vgexport -s -p -v -m /tmp/vgsap.map /dev/vgsap
vgcfgbackup -f /tmp/vgsap.conf vgsap

Integration:
vgcfgrestore -f /tmp/vgsap.conf -o /dev/rdsk/c9t0d0 /dev/rdsk/c4t0d0
vgimport -v -m /tmp/vgsap.map /dev/vgsap /dev/dsk/c4t0d0

It looks like everything goes right, but when I try to activate the volume group, I get the next message:

vgchange: Couldn't activate volume group "vgsap": I/O error while reading the VGDA.

Any help would be appreciated.

Manel,

I assume these are two machines with different (non-shared) disks?

Then you have to repeat the pvcreate, vgcreate, lvcreate, newfs, and mount/fstab stuff just like on the other machine.

If the disks are shared you do not do a vgcfgrestore but vgimport using -s.

Regards,
Bernhard
