Task 19: Back up configuration data
To configure optional features, refer to the SANavigator Software
Release 4.2 User Manual (621-000013) or EFC Manager Software Release
8.7 User Manual (620-000170) for instructions.
This section describes optional ISL performance features configured
through the SAN management or Element Manager applications.
Features include:
•
OpenTrunking - Use the OpenTrunking option from the Configure
menu (Element Manager application) to optimize ISL bandwidth.
The feature monitors data rates (congestion and BB_Credit
starvation) through multiple ISLs and load balances traffic (from
congested to uncongested links) accordingly.
•
Preferred path - Use the Preferred Path option from the Configure
menu (Element Manager application) to specify and configure
one or more ISL data paths between multiple fabric elements. At
each fabric element, a preferred path consists of a source port, exit
port, and destination Domain_ID.
•
Port fencing - Use the Port Fencing option from the Configure
menu (SAN management application) to minimize ISLs that
bounce (repeatedly attempt to establish a connection), causing
disruptive fabric rebuilds. Fencing defines a bounce threshold
that when reached, automatically blocks the disruptive E_Port.
To configure optional features, refer to the SANavigator Software
Release 4.2 User Manual (621-000013) or EFC Manager Software Release
8.7 User Manual (620-000170) for instructions. If no additional options
or features are to be configured, go to
data.
For the Sanavigator application, critical configuration data is stored
on the management server hard drive in the following directories:
•
C:\Program Files\SANavigator 4.2\CallHome
•
C:\Program Files\SANavigator 4.2\Client
•
C:\Program Files\SANavigator 4.2\Server.
