Depending on how you discover the hosts, there are recommended configurations you should
complete to avoid inaccuracy:

fabrics” on page 50)
Make sure there are Brocade HBAs on the host.
Make sure to configure the host port mapping. (refer to “Host port mapping overview” on
page 589)

Rule Violation Fix — If the policy monitor report shows a violation, the Administrator can add a
host connection to additional fabrics.
• Check for connections through two fabrics to each target LUN — This host policy monitor
enables you to determine if there are redundant connections between the host group and the
target LUN.
To prevent a single point of failure, the host should have a redundant connection to the target
LUN. Available hosts include both automatic hosts and manual hosts. An automatic host is a
host discovered through Host adapter discovery or VM Manager discovery. A manual host is a
host enclosure manually created through host port mapping in the fabric topology.
