RE: Guest Partition OS Requirements on Power8



fixed

Sue / Rob,

Am I correct that if the tape library was SAS attached as opposed to fiber, then it could be virtualized, Rob I believe this is your config.
From a performance standpoint, I've always opted with fiber over SAS attached.

From a future roadmap viewpoint, what are the options available for tape virtualization, fiber or SAS?

Paul

What are the IBM I virtualization options (host and/or guest) for
fiber attached tape, 577D?


At the present time, fibre attached tape (577D is the CCIN for feature 5735) cannot be virtualized by IBM i to any i client.

DLPARing the adapter from one partition to another is still a reasonable way to go for fibre attached tape. I used to do this on our systems by sending SSH commands to the HMC from my batch job stream.
