I am trying to get our adsm server v2.1.7 running on us/390 v1.3 to use our
3590 library.  It contains 2 drives and has worked with other mvs jobs.

I defined a devclass access sequencial, unit=3590,  estcapacity=15g, etc.

When I try archiving to a management class pointing to this device, I
receive error anr9999d and anr1461 with some text about bytes 3-4 being
invalid.
Any ideas?
