Jeff, The drive may have taken a firmware dump. Check with your local Oracle/Sun/Stk support to get current drive firmware installed.
Make sure the drive does not have the "full code" option enabled, this can the drive firmware to fail. Current tape firmware available from Oracle: 9840C 1.45.503 9840D 1.45.703 T10KA 1.46.109 T10KB 1.46.209 T10KC 1.51.318 Mike -----Original Message----- From: The IBM z/VM Operating System [mailto:IBMVM@LISTSERV.UARK.EDU] On Behalf Of Jeff Gribbin Sent: Thursday, August 04, 2011 11:36 AM To: IBMVM@LISTSERV.UARK.EDU Subject: Re: HCPDPM1280E with STK 9840C Tape Drive Thanks for the thought but I don't think that's it - there really is just one tape drive and it's in regular use from the z/OS LPARS. I HAVE (just) successfully used TAPE WVOL1 volser to write a VOL1 label onto a tape - this was part of a double-check that the tape WAS fully rewound prior to the write (from the HELP, the usual cause of HCP584I would seem to be attempting to write - in some circumstances - to a previously-written tape without ensuring one is at the beginning). However, an immediately-following TAPE DUMP * * A gave us the following on OPERATOR: 17:30:49 HCPERP2252I TAPE 0500 PATH 50 NOT OPERATIONAL 17:30:49 HCPERP2252I TAPE 0500 PATH 50 NOT OPERATIONAL 17:30:49 HCPERP602I TAPE 0500 AN INTERFACE CONTROL CHECK OCCURRED 17:30:49 HCPERP6303I SENSE = 00000000 00000000 00000000 00000000 00000000 17:30:49 HCPERP6303I 00000000 00000000 00000000 17:30:49 HCPERP6304I IRB = 04C24017 6DF3DD30 00020000 0080C400 17:30:49 HCPERP6305I USERID = MAINT 17:30:49 HCPERP2216I CHANNEL PATH ID = 50 17:30:49 HCPERP2220I PHYSICAL CHANNEL PATH ID = 0100 along with: HCPDPM1280E Device 0181 not usable; assign lost on MAINT. :sigh.
