Replacing Channels
Use this procedure to swap one channel for another. When you replace channels, some initiators in the SAN may see this as a different path to the same target and access may be affected.
If you are using Soft WWNs, refer to Replacing Channels That Use Soft WWNs for instructions.
To replace one channel for another:
-
Open SANmanager and select the Channels tab.
-
In the left pane, expand the SDS folder and highlight the storage server name.
-
In the right pane, select the channel to be replaced and choose Replace from the context menu.
-
In the Candidate Channels dialog box, select the replacement channel from the Valid Channel Replacement Candidates list, and click Replace.
-
Apply the configuration.
Notes:
-
After the Replace option, the alias of the channel remains the same and the virtual volume mappings are updated. The alias is assigned to the new channel, and the original channel is deleted. If the storage server is refreshed or restarted before the original card is removed, the original card will be rediscovered and given a new default name.
-
Mulit-port cards have at least two Fibre Channel ports. You must treat the replacement of such cards as if you were replacing distinct HBAs (2 or more). In other words, there will be two (or more) WWNs to discover and SANmanager will display two (or more) server channels for this HBA.
