Hi all,

As the subject means, i would like to migrate an IBM pseries
(7026-6H1) from aix 4.3.3 to aix 5.3.
The Firmware is "AIX 5.3 ready" (ROM Level.
(alterable).......M2P050203_condor_).

I have read IBM Migration procedure :
http://publib.boulder.ibm.com/infoce...tion_howto.htm

On this machine, i have a Volume group with EMC PowerPath physical
Volumes :

hdiskpower7 00555f2aff72acc3 statsvg
hdiskpower8 00555f2aff7d5d88 statsvg
hdiskpower16 00555f2aff725a3d statsvg
hdiskpower17 00555f2aff7d9893 statsvg

Here is EMC fileset version which are installed :

EMCpower.base 3.0.4.0 COMMITTED PowerPath Base Driver
and
EMCpower.consistency_grp 3.0.4.0 COMMITTED PowerPath Consistency
Group
EMCpower.multi_path 3.0.4.0 COMMITTED PowerPath
Multi_Pathing
EMCpower.multi_path_clariion

I know that powerpath version is no longer supported on aix 5.3.

I would like to know what is the best way to migrate correctly :

do I have to do an "exportvg statvg", uninstall EMC FIleset, migrate
aix version, install latest EMC fileset and finally importvg ?

If i export an aix 4.3.3 VG, do i will be able to import it on aix 5.3
without problems ?

Thanks in advance for your answers,

Laurent

Depending on the upgrade notes from AIX 5.3 you might have not to do
an exportvg.
If you do an exportvg keep the PVID and the VG name for reference so
you all information for an later importvg.
Meaing:
Deinstall all EMC Software incl. NAVI and reinstall after migration at
least the NAVAGENT and if needed the NAVICLI packages

Additional Note:

Since AIX 5.3 supports MPIO by default you should verify if you go
Native AIX mpio : Then you should install ODM package:
EMC.CLARiiON.fcp.MPIO.rte
This shows the disk handled by AIX as EMC ... and not as "other FC
Disk"
MPIO will bundle all pathes to a hdisk to one hdisk.

EMC PowerPath 5.1.0.0 : Then you should install ODM Package:
EMC.CLARiiON.fcp.rte
This package disabled the MPIO Support. So for each path to a disk you
will have an hdisk entry. PowerPath must be used

On a VIO Server you need the ODM Package: Package
EMC.CLARiiON.fcp.PowerMPIO.rte

Check on powerlink the failover modes for MPIO versus Powerpath
