HP-UX vPars and Integrity VM V6.3 Administrator Guide

The virtual console commands are available from the vMP Main Menu, using the hpvmconsole
command or by pressing Ctrl+B if you are already connected. The virtual console commands eject
(ej) and insert (in) allow you to control the DVD device. Both commands provide submenus for
displaying devices that are removable. Selecting options through the submenus completes the
ejection or insertion process.
If the guest hpvmconsole pc –cycle command does not complete and restart the guest, enter
Ctrl+B to interrupt the command and then press Enter to return to the virtual console. Exit the virtual
console by entering the X command. At the VSP command prompt, enter the following command
to start the guest:
# hpvmstart –P guestname
NOTE: If a guest hangs, attach the guest to the virtual console of the guest using the hpvmconsole
command, then use Ctrl+B to enter the virtual console. Enter the tc command to reset the guest.
The guest captures a memory dump of the machine state, which can be used later for offline
diagnosis. Do not terminate the guest from the VSP or power down a hung guest using the virtual
console. Doing so can corrupt the guest file system.

NOTE: When a DVD without a disk in the drive is added to a guest, specify the backing store
type null. For example,
# hpvmmodify -P guest -a dvd:avio_stor::null:/dev/rdisk/disk#
Run ioscan on the booted guest if the guest is running HP-UX.
If an empty DVD drive is given the backing store type disk, the following example shows the
result:
# hpvmmodify -P testguest -a dvd:avio_stor::disk:/dev/rdisk/disk31
hpvmmodify: WARNING (testguest): DVD or burner: '/dev/rdisk/disk31' currently has no disk.
This device may not show up or be usable by the guest when booted.
If a guest boots when configured with a DVD using the disk backing store type when there is no
disk in the drive, the guest kit utility command hpvmdevinfo (available for HP-UX guests) might
return the following results:
# hpvmdevinfo
hpvmdevinfo: Error converting (0,0,1): Error 0
Device Bus,Device,Target Backing Store Host Device Name Virtual Machine Device
Type Type Name
====== ================= ============= ================ ===========================
disk [0,0,0] disk /dev/rdisk/c2t0d0 /dev/rdisk/c0t0d0
dvd [0,0,1] disk /dev/rdisk/disk31 ??
The following phrases in the results indicate the problem of an empty DVD drive:
• The "Error converting (0,0,1): Error 0" message
• The "??" string in the field for the device name of the VM
Output appears for the dvd, because it is stored as part of the guest configuration on the VSP.
However, because there is no disk in the drive, the drive itself is not virtualized as a device within
the guest. Also, note that the DVD drive does not show up in ioscan output in the guest.
