Hi Everyone,

Currently our AIX TSM servers are lpars with all physical adapters (separate 
physical HBAs for disk and tape, and physical NICs networking).  Next year we 
will be rolling over a couple chassis to new ones, and upgrading to AIX v7.

Is anyone using VIO based tape drives on your TSM servers?
What is your experience?
How do VIO based tape drives interact with Atape load balancing in the lpar?

When we used VIO based tape drives for some storage agents, we hit a 64 target 
limit on a virtual HBA.  Seeing that we have two libraries with a total of 68 
tape drives, this seems like it will force us to stay with physical HBA's for 
tape.
