Example 15-13 Configuration Failed Due to Database Size Limits
switch-1(config)# device-alias name test8193 pwwn 21:01:01:01:01:01:01:01
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.

Resolving Mode Issues

Device alias enhanced mode is available in switches running SAN-OS Release 3.1(1) and later. In a
mixed fabric (a fabric that includes switches running Release 3.1(1) and switches running Release 3.0(x)
or earlier), an attempt to enable device alias enhanced mode fails. Unless all of the switches in the fabric
can be upgraded to Release 3.1(1) or later, you cannot enable device alias enhanced mode.
If you attempt to enable enhanced mode in a successfully merged mixed fabric, or to commit a device
alias database that enables enhanced mode to resolve a merge failure in a mixed fabric, the configuration
or the commit will fail. Example 15-14 shows the commit failure and Example 15-15 shows the
configuration failure.
Example 15-14 Commit Failure Due to Mode Conflicts
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.
Example 15-15 Configuration Failure Due to Mode Conflicts
switch-1(config)# device-alias mode enhanced
Some of the switches in the fabric are running a version of software which
cannot support enhanced mode. Please fix those switches and retry the
command.
