jfs, by default does not support files larger than 2GB.  You either have
to create a jfs filesystem with large files enabled or you have to
create a jfs2[0] filesystem to work around that.

Well, yeah.  IBM ASSumes that you'll just run mirrored VIO partitions to
get there and use MPIO in the AIX LPAR.  However, if your MPIO software
doesn't support that...

Trust me, we're getting bitten there, too.  Stupid fscking suits saved
$500 or so on a $100k SAN by going with StorageTek instead of IBM.  What
a stupid mess.  IBM has SANs that work at about the same price.  Why
deal with two different vendors?

With the latest microcode and the latest VIO server and the latest HMC
(075, 1.1.1.41, and 4.3.3, respectively), it works as-advertised.  This
was not the case in the previous revisions.


[0] You really only want to do this on 64-bit systems.  AIX 5.1 will let
     you create jfs2 slices on a 32-bit machine, but the performance
     sucks.
