General
Why can’t I install Fabric Manager or Device Manager when McAfee Internet
Suite 6.0 Professional is running?
The McAfee internet suite comes with a virus scanner, firewall, antispam, and privacy management. The
privacy management can interfere with the Fabric Manager server-client interactions. To work around
this you must shut down the privacy service.
I get an error ".sm/logon." when I downgrade from MDS SAN-OS Release 2.x (or
newer) to 1.3(x).
The installer does not support a downgrade from Cisco MDS SAN-OS Release 2.x (or newer) to Cisco
MDS SAN-OS Release 1.3(x) or earlier. Fabric Manager and Device Manager are backwardly
compatible so we suggest running the newer versions. If you still want to downgrade to the lower
version, see the “Downgrading the Management Software” section on page 1-9.

Why do I get errors while monitoring Area chart graphing?
When doing the area chart graphing from the monitor window, if you move the mouse over the Area chart
before the first data comes back, you see a java.lang.ArrayIndexOutOfBoundsException error on the
message log from JChart getX(). This is because JChart tries to locate a value that does not exist yet.
This might be fixed in a future version of JChart.
Why do I get “gen error” messages?
Usually a "gen error" means that the SNMP agent on the switch had an unexpected error in the process
of serving an SNMP request. However, when you are accessing the switch through a VPN connection or
any sort of NAT scheme, all errors are reported as gen error. This is a known problem and will be fixed
in a future release. You can verify whether this was the reason behind your gen error by trying to
reproduce this error in an environment where there is no network address translation (where you are on
the same network as the switch).
Why are disk images in the Device Manager Summary View not showing up?
On some occasions the Summary View table in the Device Manager does not show the icons for disks
attached to a Fx port. This is because the FC4 features are empty for this port. A LUN discovery must
be issued to discover information about these hosts/disks that do not register their FC4 types. You can
do this in the Device Manager by clicking FC > Advanced > LUNs.
