Hi Everyone . . . expecially SAN experts . . . .

I have a 3494 library with 3590H drives that connect to a AIX system via
SAN.
The SAN switch is a Brocade.  Below is the switchshow cmd for this switch.

The F-Ports are the AIX adapters while the L-Ports are the 3590 drives.
There is no zoning on the switch - all AIX HBA's see all drives, then
atape picks the least busy path to use.

We might want to add another library with 3592 tape drives to the TSM
server and this switch.

Questions . . . .

1) Zoning

If I add some host adapters and new library/drives to this same switch
(keeping new drives/libraries on separate HBA adapters),  Is there
anything special about zoning fcal L-Ports to the F-port AIX adapters?
(We've never played around with L-Ports.  Everything else we have are
fabric ports).

Would you create a zone per AIX HBA with one libraries drives, or,
one zone per library with all the HBA's and drives in the one zone?

2)  Sharing HBA's

Is it possible to share the existing HBA's with both a new
library/drives (3592) and the existing library/drives (3590)?

Is this advisable?

In other words, is it better to keep lib/drives on separate
host hba's?

Thanks

Rick
