Applying a new configuration
You can apply a new OFM configuration from the main Open Fabric Manager
page on the AMM Web interface.
1. Login to the AMM Web interface.
2. In the left pane, under Blade Tasks , select Open Fabric Manager . The Open
Fabric Manager Configuration Management page will open in the right pane.
3. Select Apply a Configuration . The Apply a Configuration page will open in
the right pane.
4. Click Browse to locate the configuration file you want to apply.
5.
You can click
Advanced Options
to override checks that protect against
address duplication.
a. If you select Ignore duplicate virtual addresses in the configuration file
under Advanced Options , the AMM will not check for address duplication.
b.
If you select Force the configuration to be applied to powered on blades
under Advanced Options , the AMM will not check the power state of the
blades.
Note: In general, you should not change the OFM configuration while the
blade is powered on. Changing the OFM configuration while the
blade is powered on can lead to duplicate addresses, and unexpected
results.
c.
If you select
Continue on error
under Advanced Options, the AMM will
continue on most errors. Ignoring some of these errors may lead to address
duplication. For example if the AMM is unable to connect to one of the
chassis it will continue even though that chassis might be using an address
that is now assigned to a different chassis.
6. After you locate your configuration file and select advanced options, click OK .
The AMM will start to prepare for applying the new OFM configuration and
any errors that occur during this process will be reported.
Note: If the new configuration is identical to the current configuration, then a
No Configuration Change page will display.
Before the configuration is applied, the AMM displays the expected OFM
changes. There is a single line displayed for each chassis that has changes. If
the OFM configuration for a given slot is changed, the corresponding cell in the
table contains an icon, otherwise the cell is blank. If OFM is enabled for that
slot, the icon is blue. If OFM is disabled for that slot, the icon is gray.
7.
If you approve the changes, click Continue .
At this point the AMM starts to apply the OFM configuration. As explained in
“Avoiding address duplication” on page 18, the first phase is to disable the OFM
configuration for all the slots that are about to be reconfigured. The next phase is
to apply the new configuration for all of the slots. Finally, OFM is re-enabled on
the appropriate slots. When the process completes, The configuration file was
applied successfully page will appear in the right pane of the AMM Web interface.
Viewing the configuration in a local chassis
After you change the OFM configuration, you can view it on any of the chassis.
1. Login to the AMM Web interface.
2. In the left pane, under Blade Tasks , click Configuration . The Configuration
page opens in the right pane. The Configuration page contains an Open Fabric
