Cannot importvg

Hi,

I try to transfert disk from one machineA (AIX5.1) to another machineB
(AIX5.3)
with SAN EMC.
on machineA
- umount
- unmasking

on machineB:
- masking: OK
- cfgmgr: OK => new disks
- when I try to importvg I have the error below:
what is wrong ?
Thanks

#importvg -f -y testvg hdiskpower5
0516-024 lqueryvg: Unable to open physical volume.
Either PV was not configured or could not be opened. Run
diagnostics.
0516-024 lqueryvg: Unable to open physical volume.

0516-1140 importvg: Unable to read the volume group descriptor area
on specified physical volume.

Not sure what this unmasking may be, but there ia a varyoffvg missing.
And if you don't plan to put the disks/VG back to this system in the
future, an exportvg would be a good idea too.

could there still be a reservation on the disks the varyoffvg on
the 5.1 system would have cleared? Check the errpt -a. See if
the EMC software provides some command to list and break reservations.

I'm also nat familiar with "unmasking" but one of the things I found
clears up a lot of these issues is to remove/recreate all the EMC
devices and re-import the volume group. Here is a little script we've
used for years.

Good Luck - Steve

#
# rm powerdisk device files
#
lsdev -Cc disk|grep hdiskpower|awk '{print $1}'|while read hdiskpower
do
echo "rmdev -dl $hdiskpower"
rmdev -dl $hdiskpower
if [ $? -ne 0 ]
then
echo "rmdev -dl $hdiskpower failed"
exit 1
fi
done

#
# rm EMC device files
#
lsdev -Cc disk|grep EMC|awk '{print $1}'|while read emcdisk
do
echo "rmdev -dl $emcdisk"
rmdev -dl $emcdisk
if [ $? -ne 0 ]
then
echo "rmdev -dl $emcdisk failed"
exit 1
fi
done

exit 0
