It looks like one of the disks was not read.

EIther

1) it does not have the dev/dsk or /dev/rdsk file as in

Or

2) there was a read error in reading the LVM headers in one or more disks.

Most likely the second.

How many disks were in the "vgora" group and how many were vgimported?

hi,

it seems not all the disks were imported.

It may caused by different device name when you import the disks from other servers.

If its disks in san storage, check the zoning. Zoning for both servers must include access to these disks.

Check for output in ioscan for both servers and compare:
# ioscan -funC disk

And perform pvdisplay for the disks to determine its content.
# pvdisplay -v /dev/dsk/c#t#d#

Hi Pankaj,

This is happening because you are trying to import a disk that has missing device files.

Perform the following steps to resolve your errors:

#insf -e
# ioscan -fnC disk
then
#vgimport
