Cisco Nexus 5000 Series Switch CLI Software Configuration Guide (OL-16597-01, July 2009)

If session locks remain on remote switches after using the no zone commit vsan command, you can use the
clear zone lock vsan command on the remote switches.
switch# clear zone lock vsan 2
We recommend using the no zone commit vsan command first to release the session lock in the fabric.
If that fails, use the clear zone lock vsan command on the remote switches where the session is still
locked.
Note
Merging the Database
The merge method depends on the fabric-wide merge control setting:
• Restrict—If the two databases are not identical, the ISLs between the switches are isolated.
• Allow—The two databases are merged using the merge rules specified in the following table.

The merge process operates as follows:
• The software compares the protocol versions. If the protocol versions differ, then the ISL is isolated.
• If the protocol versions are the same, then the zone policies are compared. If the zone policies differ,
then the ISL is isolated.
• If the zone merge options are the same, then the comparison is implemented based on the merge control
setting.
◦ If the setting is restrict, the active zone set and the full zone set should be identical. Otherwise, the
link is isolated.
◦ If the setting is allow, then the merge rules are used to perform the merge.
