X-posted - IBMVM & LINUX-390 When we attach a tape drive (3590) to a Linux guest, the tape driver attempts to execute an assign operation on the device which is getting an error:

Before, I go any further is this a problem anyone else has seen? If not, I'll go through normal channels (actually I'll probably do it in parallel). Neale
