Integrity VM CommandManagement Function
vMP> ej
Eject a virtual DVD.
vMP> in
Insert a virtual DVD
NOTE: When a DVD without a disk in the drive is added to a guest, specify the backing store
type of null, for example:
# hpvmmodify -P guest -a dvd:scsi::null:/dev/rdisk/disk#
Run ioscan on the booted guest if the guest if 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:scsi::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 type of results:
# hpvmdevinfo
hpvmdevinfo: Error converting (0,0,1): Error 0

disk [0,0,0] disk /dev/rdsk/c2t0d0 /dev/rdsk/c0t0d0
dvd [0,0,1] disk /dev/rdisk/disk31 ??
The following results indicate a problem of an empty DVD drive:
• The "Error converting (0,0,1): Error 0" message
• The "??" string in the field for the virtual machine's device name
Output appears for the dvd , because it is stored as part of the guest configuration on the VM
host. 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.
7.3.1.3 Guest User
The guest user runs applications on a guest OS. Access is provided and limited by the guest
administrator. There are no Integrity VM storage requirements for application users of the guest
OS.
There are no Integrity VM storage commands for application users in the guest OS. The guest
users use Integrity VM storage on the guest OS the same way as they normally use storage on
an HP Integrity server. Any required Integrity VM storage changes must be directed to the guest
administrator or VM Host administrator.
7.3.2 Integrity VM Storage Use Cases
This subsection describes ways to use the Integrity VM storage commands.
7.3.2.1 Adding Virtual Storage Devices
A VM Host administrator adds or attaches Integrity VM storage using the hpvmstatus and
hpvmmodify commands. Virtual storage devices can be added or attached while the virtual
