For attached devices, modifications are made physically on the device. The guest OS supplies
commands for loading and unloading tapes using media changers. But loading new media into
the media changer, changing tapes in standalone drives, and changing discs with CD/DVD
burners are accomplished manually. This process requires cooperation between the VM Host
administrator and the guest administrator.
NOTE: 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 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.
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.
