#

A virtual disk backend is a location where virtual disk data is stored. A disk, disk

slice, file, or volume (such as ZFS, SVM, and VxVM) can be used for the

backend.

In the control domain, register the

install_disk

file on a built-in disk as a virtual

disk backend. The I/O domain recognizes this disk as a virtual disk. The device name

of this virtual disk is

/dev/[r]dsk/c0d0

. In the I/O domain, register an HDLM

device used in the storage system as a virtual disk backend. The guest domain

recognizes this disk as a virtual disk.
In this configuration example,

/dev/dsk/c4t50060E8010027A82d0s2

and

/dev/

dsk/c4t50060E8010027A82d1s2

are HDLM devices.

An LDoms domain setting example is shown in Table 3-34: LDoms Setting Example.
