exportvg/importvg across AIX versions (using SAN disk)
sdpeck
be, but is this possible?
Two systems on the same SAN, one is 5.2 ML5, the other 5.3 ML4. If I
exportvg my vg's from the 5.2 system (H80), and the LUNs are in the
same zone as my 5.3 system (570), can I simply importvg those same
vg's on the new system?
Any problems going from 5.2 to 5.3?
TIA,

Ensure it's available on the other node
cfgmgr
you should be able to see matching pvid's
If you can see the disk but not the pvid,
chdev -l hdisk# -a pv=yes
You should then be able to
importvg -y vgname hdisk#

if you have varied off the Volumegroup on the source side, you are able
to import this Volumegroup on your target system.
But to be able to import a Volume Group, you need to have the PVIDs
visible.
If the hdisks are available on the target system, but "lspv" showes no
PVID, you should use "rmdev -l hdisk<X>" to switch the hdisks to
"defined". If all disks are "defined", "cfgmgr" should bring back all
hdisks to "available" and should have read the PVIDs into the ODM.
If lspv showes the former used PVIDs, you should be able to import the
Volume Group.
If you have changed the PVIDs, using "chdev -l hdisk<X> -a pv=yes", you
can use "recreatevg" to recover this VolumeGroup and update the VGDAs.
Best regards,

There are no problem going from 5.2 to 5.3. But if you modify the
VG on the 5.3 side you might not be able to go back to 5.2. I
don't remember specifics, but the 'huge' VG size might be such an
option.
