Client in a local or remote client machine
(Windows and Linux) Collapse the topology fabric groups and check the CPU utilization.
If it is reduced, this could be caused by the video adapter driver installed on the machine.
Some video adapters (such as NVIDIA Quadro NVS 135M) can cause CPU issues and it is
recommended that you upgrade the driver version to a later version or one that we
support or have tested.
You can download the appropriated drivers from your graphics card manufacturer's web
site.
Table 14 lists the video adapter cards that have been tested.

Problem Resolution
If a switch is replaced by another switch having
the same IP address but a different node WWN
while fabric tracking is on, the Management
application does not update the Product List,
Connectivity Map or switch properties with the
new node WWN. Choose from one of the following options:
•
Turn fabric tracking off while the switch is replaced. This causes the old switch to be
removed and the new switch added.
•
After the switch is replaced, remove and re-add the fabric in the Discover Setup
dialog box.
