3. Creating an HDLM Environment
137
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
sd
or
ssd
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/c2t50060E8010027A82d0s2
and
/dev/
dsk/c2t50060E8010027A82d1s2
are
sd
or
ssd
devices.
An LDoms setting example is shown in Table 3-21: LDoms Setting Example.

The following figure shows a configuration example for an LDoms environment
before installing HDLM.
