Hi Juan,
I would set up the Brocade switches a little different
in such a way as to separate disks and tape into
different zones:
Zone1: backup server (2xHBA) + storage node1 (2xHBA) +
storage node2 (2xHBA) + disks
This assumes that you use selective storage
presentation of the disks in your cabinet to restrict
access to only the proper HBA's
Zone2: backup server + storage node1 (1xHBA) + storage
node2 (1xHBA) + tapes
This assumes you can do selective storage presentation
on your tape drives (in your MDR/NSR). If this isn't
possible create one zone for each NetWorker server
with the proper HBA and the proper tape drives.
I'm not sure what HP has to say about running tape
drives over SecurePath, maybe you should check with
them.
And before you go to Microsoft, you should know that
they DO NOT support disk and tape on the same HBA!
Hope this is more help than confusion! :)
Regards,
Matts
