Note

Cannot Log Into Fabric Manager

Fabric Manager uses the SNMP user name/password combination to communicate with the switch. The
SNMP user name is automatically synchronized with the CLI user names configured. If you use the
administrator password recovery procedure, you must manually reset the administrative password on the
switch to resynchronize the SNMP and CLI user name and password. See the
Administrator Password" section on page

Cannot Upgrade Fabric Manager

If you attempt to upgrade Fabric Manager by pointing your web browser at a switch running Cisco
SAN-OS 3.0(1) through SAN-OS 3.1(3), you may encounter an issue where the upgrade does not
complete. You should open the Java Web Start application on your desktop and disable HTTP proxy. If
you are using Microsoft Windows, open Java Web Start and choose File > Preferences to access the
HTTP proxy settings.
Starting with SAN-OS 3.2(1), Fabric Manager is installed or upgraded from a CD-ROM or from
Note
Cisco.com.

The Map Shows Two Switches Where Only One Switch Exists

If two switches show on your map, but you only have one switch, it may be that you have two switches
in a non-contiguous VSAN with the same domain ID. The Fabric Manager uses the VSAN ID and
domain ID to look up a switch, and this can cause the fabric discovery to assign links incorrectly between
these errant switches.
The workaround is to verify that all switches use unique domain IDs within the same VSAN in a
physically connected fabric. (The fabric configuration checker will do this task.)

Old Devices Appear on the Map

If you are running a SAN-OS 3.1(3) or earlier, and if old devices appear on your fabric map, it may be
that you made changes to the fabric topology, such as changing a switch IP address or removing a device,
but launched Fabric Manager with the Accelerate Discovery check box checked.
The workaround is to log out and then log back in without checking the Accelerate Discovery check box.
