In February 2007, Chris Little reported receiving the message HCPDPM1280E Device 0181 not usable; assign lost
while attempting to write to a tape cartridge loaded into a STK 9840C tap e drive. As far as I can see, no resolution was posted at the time. I am experiencing exactly these symptoms with the same device-type. The device has been in regular use on several z/OS LPARS on the same machine without any problems but we have never previously attempted to use it fro m the z/VM LPAR. After being taken offline to the z/OS LPARS the device happily comes onli ne to z/VM and can be attached to a CMS user who can successfully read the t ape (well, TAPE DVOL1 works) but any attempt to write to the tape immediately elecits a brief delay (about 5 seconds) followed by the HCP1280E. (I hav e tried MOVEFILE and TAPE DUMP - identical symptoms in both cases.) The cartridge has been double-checked and is definitely set for write-permit. I'm hoping that maybe somebody did discover a resolution but for whatever reason it either didn't get posted or I've been looking in the wrong plac e! Thoughts, anybody? TIA Jeff Gribbin
