Persistent entries take precedence over company ID configuration. If the HBA fails to discover
a target, verify that the HBA and the target are connected to the same switch and have the same
area in their FC IDs, then perform the following procedure:
1. Shut down the port connected to the HBA.
2. Clear the persistent FC ID entry.
3. Get the company ID from the Port WWN.
4. Add the company ID to the list that requires area allocation.
5. Bring up the port.
A persistent FC ID configuration always takes precedence over the list of company IDs. Even if the
company ID is configured to receive an area, the persistent FC ID configuration results in the
allocation of a single FC ID.
New company IDs added to subsequent releases are automatically added to existing company IDs.
The list of company IDs is saved as part of the running and saved configuration.
The list of company IDs is used only when the fcinterop FC ID allocation scheme is in auto mode.
By default, the interop FC ID allocation is set to auto, unless changed.
We recommend that you set the fcinterop FC ID allocation scheme to auto and use the company
ID list and persistent FC ID configuration to manipulate the FC ID device allocation.
Use the fcinterop FCID allocation auto command to change the FC ID allocation and the show
running-config command to view the currently allocated mode.
When you issue a write erase, the list inherits the default list of company IDs shipped with a
relevant release.
