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.
