Failed SWWN : 00:00:00:00:00:00:00:00
SAP : 0 Status: success Expln:
The failed SAP in Example 15-11 is 110 (IVR). Unless the IVR lock is released, you cannot commit the
device alias database changes.
Resolving Database Size Issues
The maximum size of the device alias database increased from 8K to 20K for switches running SAN-OS
Release 3.1(1) or later. If the fabric includes switches running SAN-OS Release 3.0(x) or earlier and
switches running Release 3.1(1) or later, the maximum size of the device alias database is limited to 8K.
This is the limit imposed on the switches running Release 3.0(x) or earlier. Unless all of the switches are
upgraded to Release 3.1(1) or later, you cannot configure more than 8K device aliases.
If you attempt to configure or commit a device alias database that exceeds the maximum size supported
in the fabric, the configuration or the commit will fail. Example 15-12 shows the commit failure and
Example 15-13 shows the configuration failure.
Example 15-12 Commit Failure Due to Database Size Limits
switch-1(config)# device-alias commit
Some of the switches in the fabric are running a version of software which
cannot support either the issued command or maximum device-alias limits.
Please fix those switches and retry the command.
