Note 1
Ownership of volumes is not visible to hosts. However, in SMU you can view volume ownership and change the owner of a
virtual disk and its volumes.
Note 2
Changing the ownership of a virtual disk should never be done with I/O in progress. I/O should be quiesced prior to changing
ownership.
In the following configuration, both hosts have redundant connections to all mapped volumes.

If a controller fails, the hosts maintain access to all of the volumes through the host ports on the surviving controller, as
shown in the Figure 4.
