HP vPars and Integrity Virtual Machines V6.1 Administrator Guide

files 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 following ISO files:
# ls -l /var/opt/hpvm/ISO-images/hpux
total 26409104
-rw-r--r-- 1 root sys 3774611456 Jul 11 :59 0505-FOE.iso
-rw-r--r-- 1 root sys 4285267968 Jul 11 17:05 0512-FOE.iso
-rw-r--r-- 1 root sys 3149987840 Jul 11 18:42 0603-FOE-D1.iso

The Virtual NullDVD resource statement is
dvd:avio_stor::file:/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/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 9.2.1.3 (page 118)). To mark the directory sharable
across virtual machines, 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 11.11 (page 189).
Virtual NullDVDs require no additional management beyond that required for the Virtual DVD (see
Section 9.2.2.3.4 (page 127)) or Virtual FileDVD (see Section 9.2.2.3.5 (page 128)) types they
become.
9.2.2.3.7 Attachable devices
vPars and Integrity VM allows you to attach physical VSP backup device types to vPars/VMs. VSP
backup device types are tapes, media changers, and CD/DVD burners. These devices are specified
on the VSP using HP-UX agile esctl device files. Use of the agile esctl device files are
recommended, because they are per physical device not per path.
The guest OS running on the vPar/VM has full control over an attached physical device. Therefore,
the guest OS must support the device being attached. For a list of supported guest OS drivers, see
the device's product documentation.
The resource statements for attached devices take the following forms depending upon device type:
• For magnetic tape:
tape:avio_stor::attach:/dev/pt/pt_tape#
• For media changers:
changer:avio_stor::attach:/dev/pt/pt_autoch#
• For CD/DVD burners:
burner:avio_stor::attach:/dev/pt/pt_disk#
where /dev/pt/pt_* files are HP-UX esctl device files.
Attachable devices are specified as avio_stor.
To create an HP-UX esctl device file, follow these steps:
1. Run ioscan to pick up any new devices that were connected:
# ioscan
2. Locate the device designated for attachment.
a. Install any device special files for these new devices:
# insf -e
b. Verify whether the new devices were claimed by VSP:
