HP vPars and Integrity Virtual Machines V6.1 Administrator Guide

In this example, the Virtual LvDisk resource statement is
disk:avio_stor::lv:/dev/lvrackA/rdisk2.
To use VxVM, the Virtual LvDisk resource statement takes the following form:
disk:avio_stor::lv:/dev/vx/rdisk/dg_name/v_name
where /dev/vx/rdisk/dg_name/v_name is a VxVM character device file for volume v_name
on disk group dg_name. To display the VxVM character device file name, enter the following
command:
# vxprint
Disk group: rootdg

To use VxVM, the Virtual LvDisk resource statement is
disk:avio_stor::lv:/dev/vx/rdisk/VxvmTest1/vxvm_2. For information about adapters
that support VxVM, see the HP-UX vPars and Integrity VM V6.1 Release Notes at http://
www.hp.com/go/hpux-hpvm-docs.
For information about multipath solutions for Virtual LvDisks, see Section 9.2.1.3 (page 118).
9.2.2.3.3 Virtual FileDisks
A Virtual FileDisk is an emulated AVIO disk whose virtual media comes from a VSP file. The VSP
file is specified using the absolute pathname to the file. The file can be on a VxFS file system locally
mounted on the VSP. NFS file systems are not supported for Virtual FileDisks.
Virtual FileDisks cannot be shared simultaneously across active virtual machiness. Only one active
vPar/VM can be given a particular Virtual FileDisk resource at a time. Virtual FileDisk resources
can be changed dynamically between active vPars/VMs (see Section 9.3 (page 133)).
The file systems used for Virtual FileDisks need to be managed to prevent data corruptions. To help
with accounting, it is recommended that all files under a given directory be used with a single
vPar/VM. Additionally, it might help to allocate file directories from complete logical volumes or
whole disks to make the accounting even easier. For more information, see Section 9.2.1.4
(page 119).
