HP-UX guest OS crash might fail to save a crash dump with the following console message:

Error: can't open first dump device /dev/dsk/c0t0d0. Dump aborted. INIT[0]: OS_INIT ends. Resetting the system

This problem is caused by the HP-UX MPT dump driver in the guest waiting only 1 second for a bus reset to finish. If there is an attached tape or changer sharing the same virtual MPT adapter as the guest boot disk, the reset time of that attached tape or changer might exceed the 1 second timeout, resulting in the error message above.

To avoid this problem on HP-UX 11i v2 0505–0706 or HP-UX 11i v3 guests, make sure the guest boot disk and any attached tape or changer do not share the same virtual MPT adapter. For information about how to specify bus and device numbers to place the tapes or changers on a separate MPT adapter than the guest boot disk, see the hpvmresources manpage or the HP Integrity Virtual Machines Installation, Configuration, and Administration.

For HP-UX 11i v2 0712, HP-UX 11i v3 0803, and all later supported HP-UX guest releases, make sure the HPVM-Guest depot is installed. The HPVM-Guest depot adjusts the MPT dump reset timeout allowing for tape and changers to be placed on the same virtual MPT adapter as the boot disk.
