    Hello,
    I have a basic lpar running 5.3 TL8 with internal rootvg and external San connectivity thru 2 HBAs. I am looking to move this lpar to another p5.
    Both manged servers are under the same HMC control. I could just "pull" the internal rootvg hdisks and insert into new lpar and possibly "move" the fiber
    over to the hbas on the new server. I'm looking for some guidance,gotchas. No VIO involved. Any thoughts,ideas to this process. Thanks in advance to all responses.
    Regards,
    Tom

    for rootvg, you can use mksysb to clone the new system.

    for external san connectivity, you can export the vg's to new system.

    you need san guy help when you want to export vg's to new machine.

    i hope , this will help you.

    thanks

    Thank you for the response.
    If I was looking to move the HBA's, (fiber) . clone the rootvg to keep all the
    current devices, move the etherent to basically have the same host on a different
    machine, then DO you think this might be a cleaner/simplier method?
    Thanks again

    Our LPARs boot from SAN devices, so our configuration is a little simpler. However, I've had very few problems when moving the HBAs from one chassis to another. Naturally, your O/S patch level, firmware level, etc. has to match up and work together, and you'll probably have to re-do the entire TCP/IP configuration unless you're moving the NICs as well... Our standard AIX build always includes all device drivers to make that process a little safer...

    If you want to move the fibre channel cables to different HBAs, you'll have to get new SAN zoning and SAN disk presentation done, and you may see different hdisk# (or vpath# or hdiskpower#, etc.) devices when you boot in the new environment. However, so much of AIX's LVM processing is based on the PVID, that those changes rarely cause problems in my shop...

    Good luck!
