Depending on how you discover the hosts, there are recommended configurations you should
complete to avoid inaccuracy:
-
Fabric discovery for manual host enclosures to fabric connections (refer to “Discovering
fabrics” on page 37)
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 553)
-
Host adapter discovery with 2.1 or later driver for host to unmanaged fabric connections

Rule Violation Fix — If the configuration policy manager 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 configuration policy
manager 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.
