Using Device Aliases or FC Aliases
You can change whether Fabric Manager uses FC aliases or global device aliases from Fabric Manager
client without restarting Fabric Manager Server.
To change whether Fabric Manager uses FC aliases or global device aliases, follow these steps:
Step 1 Click Server > Admin.
You see the Admin dialog box in Figure 31-3.
Figure 31-3 Server Admin Dialog Box
Step 2 For each fabric that you are monitoring with Fabric Manager Server, check the Device Alias check box
to use global device aliases, or uncheck to use FC aliases.
Step 3 Click Apply to save these changes or click Close to exit the dialog box without saving any changes.
Device Alias Statistics Cleanup
To clear device alias statistics (for debugging purposes), refer to the Cisco MDS 9000 Family CLI
Configuration Guide.
Database Merge Guidelines
Refer to the “CFS Merge Support” section on page 13-9 for detailed concepts.
When merging two device alias databases, follow these guidelines:
• Verify that two device aliases with different names are not mapped to the same pWWN.
• Verify that two different pWWNs are not mapped to the same device aliases
• Verify that the combined number of the device aliases in both databases does not exceed 8191 (8K).
For example, if database N has 6000 device aliases and database M has 2192 device aliases, this
merge operation will fail.
