IMPORTANT: One way to determine what is happening is to look at the log messages during
discovery and getting element details. See ”Viewing Log Messages” on page 71 for more
information.
Undiscovered Hosts Display as Storage Systems
On rare occasions, undiscovered hosts will display as storage systems in System Manager.
Specifying the host’s WWN in the jboss.properties file will cause the host to display correctly.
Follow these steps to modify the jboss.properties file:
1. Determine the host’s WWN. This information is available on the IEEE Standards Association
web site at http://standards.ieee.org/regauth/oui/oui.txt.
2. Go to the %JBOSS4_DIST%\server\appiq\conf directory on the management server.
3. Open the jboss.properties file in a text editor and locate the hostPortWWNs property.
4. Uncomment the property and enter the host’s WWN in hex format. Multiple WWNs can be
entered as a comma-separated list. For example:
hostPortWWNs=00-01-C9,00-01-C8
5. Restart the service for the management server.
Solaris Machines Appear to Have Extra QLogic HBAs
Solaris machines using fibre channel drives internally will always appear to have extra QLogic
HBAs. After discovering a Solaris machine, internal fiber channel drives will show an extra QLogic
adapter on the host adapters page.
No Stitching for Brocade Switches with Firmware 3.2.0
Stitching does not appear for hosts attached to Brocade switches running firmware 3.2.0. There is
no stitching when the PID format is 0. The port setting must be the same for all Brocade switches in
the fabric or the fabric will become segmented. The PID format should be set to 1 for all Brocade
switches running firmware later than 2.6.0 and 3.0. The PID=0 setting is a legacy Port ID format
that does not support the numbers of ports beyond 16.
Link Between a Brocade Switch and a Host
Disappears from the Topology
If a link that used to work between a Brocade switch and a host disappears from the topology, you
may need to rediscover the Brocade switch and the host. Also, confirm that both are online and
there are no network connection issues. As a last resort, you may need to reboot the switch. In
some instances, the API of the Brocade switch has been known to hang. Rebooting the switch
clears the switch of the API hang.
Incorrect Topology Sometimes Displayed for CNT Switches
The CNT SMI-S provider for CNT switches does not return the correct topology information when
more than one fabric is managed by the same InVSN™ Storage Network Manager. McDATA,
which completed its acquisition of CNT in the summer of 2005, has been made aware of this
issue.
