Installing HDLM in an LDoms Environment

This section explains how to install HDLM in a system configuration in which

HDLM-managed sd or ssd devices are assigned as virtual disks for the guest

domain.

The following figure shows a configuration example before installing HDLM.

Figure 3-6 Configuration Example (Before Installation)

#

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.

The following table shows a setting example of LDoms domain.
