FC ID Allocation for HBAs
Tip 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 enter a write erase, the list inherits the default list of company IDs shipped with a
relevant release.
To allocate company IDs, perform this task:
The following example adds a new company ID to the default list:
switch(config)# fcid-allocation area company-id 0x003223
Verifying the Company ID Configuration
You can view the configured company IDs by entering the show fcid-allocation area command. Default
entries are listed first and the user-added entries are listed next. Entries are listed even if they were part
of the default list and you later removed them.
The following example displays the list of default and configured company IDs:
switch# show fcid-allocation area
FCID area allocation company id info:
00:50:2E
<-------------------- Default entry
00:50:8B
00:60:B0
00:A0:B8
00:E0:69
00:30:AE +
<------------------ User-added entry
00:32:23 +
00:E0:8B *
<------------- Explicitly deleted entry (from the original default list)
Total company ids: 7
+ - Additional user configured company ids.
* - Explicitly deleted company ids from default list.
You can implicitly derive the default entries shipped with a specific release by combining the list of
Company IDs displayed without any identification with the list of deleted entries.
You can also view or obtain the company IDs in a specific WWN by entering the show fcid-allocation
company-id-from-wwn command. Some WWN formats do not support company IDs. In these cases,
you many need to configure the FC ID persistent entry.
