to use from the virtual console. The file directory must be a locally mounted VxFS file system. NFS
file systems are not supported. If the ISO files are world writable, they are not available from the
virtual console for the ISO files listed.

The Virtual NullDVD resource statement form is
dvd:avio_stor::null:/var/opt/hpvm/ISO-images/hpux/.
You can configure the Virtual NullDVD to be sharable or have multipath options. If the Virtual
NullDVD device is configured to use the VSP CD or DVD device, it is not sharable and no multipath
options are available. If the Virtual NullDVD is configured to use a file system directory, it is sharable
and you can use multipath options (see Section 6.4.1.3 (page 69)). To mark the directory sharable
across VMs, you can use the hpvmdevmgmt command. For example,
# hpvmdevmgmt -m gdev:/var/opt/hpvm/ISO-images/hpux/:attr:SHARE=YES
For more information about using the hpvmdevmgmt command, see Section 13.19 (page 248).
Virtual NullDVDs require no additional management beyond that required for the Virtual DVD (see
Section 6.4.2.3.4 (page 81)) or Virtual FileDVD (see Section 6.4.2.3.5 (page 83)) types.
6.4.2.3.7 Attachable devices
vPars and Integrity VM allows you to attach physical VSP backup device types to vPars or VM
guests. VSP backup device types are tapes, media changers, and CD or DVD burners. These
devices are specified on the VSP using their respective lunpath hardware path (displayed only in
ioscan with the -N option). For more information about how to find lunpath hardware path for
a given physical device, see Section 6.4.2.4.1 (page 86).
The guest OS running on the vPar and VM guest has full control over an attached physical device.
Following are the resource statement forms for attached devices depending upon the device type:
• For magnetic tape:
tape:avio_stor::attach_path:lunpath_hardware_path
• For media changers:
changer:avio_stor::attach_path:lunpath_hardware_path
• For CD or DVD burners:
burner:avio_stor::attach_path:lunpath_hardware_path
The following example shows the resource specifier for an attached tape device:
tape:avio_stor:0,4,0:attach_path:0/7/1/1.0x500104f00048b29e.0x0
For more information about attached I/O support and configuration, see Section 6.4.2.4 (page 86).
As with virtual devices, attached devices can be attached and detached dynamically across active
vPars or VM guests (see Section 6.5 (page 92)). Also, while the device is being attached to a vPar
or VM guest, it cannot be opened by the VSP at the time of or during attachment.
Because tapes, media changers, and CD or DVD burners are not virtualized, media changes with
these must be done physically. Therefore, all media changes with attached devices must be done
by individuals with access to that physical storage. Changes to attached devices might require the
device to be unlocked from an active guest OS. Attached devices remain in the last lock state the
guest OS put it in when the device is detached or the VM is shut down. Empty devices are attached
and are not locked.
