    I didn't look at it yet but what about the veritas stuff you can get for HP?

    Those numbers are beyond my companies needs :). Once I configured an IBM ESS
    with 6 Tb but that had a max lun size of 200 Gb. I could put those in 1
    volume group but made the file systems never bigger as a lun to keep things
    simple.

    I have no idea why you would need a file system of 2 Tb. Now you made 2 of
    1.5 Tb you could also make 2 volume groups to keep below the 2 Tb limit
    since you have 2 disk devices. What kind of disk cabinet you have? I never
    seen a cabinet supporting such large luns.

    Most times performance is a issue too and you benefit from having multiple
    luns that you can spread over multiple fiber/scsi paths.

    what's HP opinion about your configuration? I guess they are a bit supprised
    :)
