When using client-side encryption with key=generate, when I try either backup 
or archive directly to a tape pool, the client will try to mount volumes until 
it failes.

Tsm windows client 7.1.4, server 7.1.7.1 on RHEL 6.9.

Collocation is set to group (default) on the tape storage pool.
Any ideas out there?
Believe it or not, tape runs faster than disk on my servers, so this would 
speed up the process.
