Hi Luke

Many thanks for the info. Doing things for the first time is always a
little nerve racking.

We did look at the fibre attach option, but our only real requirement is
more storage space at the moment as our single 3494 lib is starting to groan.

Thanks again

Hi Farren,
    I assumed you were going to attach your H1A's via fiber - if you're
staying
SCSI you won't have any issues.  Yep, we are *attempting* to go with fiber
attached drives through an IBM 2109 F-16 switch and are having a few issues.
Should be much better in the future (allow us to share eight H1A drives among
three servers on a need basis) but we just can't get it up and running just
yet...  Good luck to you - feel free to ask if you've got any questions.
