Cisco MDS 9000 Series Configuration Guide

Enabling Automatic Zone Pending Diff Display
To enable the display of pending-diff and subsequent confirmation on issuing a zone commit in enhanced
mode, follow these steps:
Step 1 switch# configure terminal
Enters configuration mode.
Step 2 switch(config)# zone confirm-commit enable vsan vsan-id
Enables the confirm-commit option for zone database for a given VSAN.
Step 3 switch(config-zone)# zone commit vsan 12
If the zone confirm-commit command is enabled for a VSAN, on committing the pending database, the pending-diff is
displayed on the console and the user is prompted for Yes or No. If the zone confirm-commit command is disabled, the
pending-diff is not displayed and the user is not prompted for Yes or No.
Step 4 switch(config)# no zone commit vsan 12
If the zone confirm-commit command is enabled for a VSAN, on discarding the pending database, the pending-diff is
displayed on the console and the user is prompted for Yes or No. If the zone confirm-commit command is disabled, the
pending-diff is not displayed and the user is not prompted for Yes or No.
Releasing Zone Database Locks
To release the session lock on the zoning database on the switches in a VSAN, use the no zone commit vsan
command from the switch where the database was initially locked.
switch# configure terminal
switch(config)# no zone commit vsan 2
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
Creating Attribute Groups
In enhanced mode, you can directly configure attributes using attribute groups.
To configure attribute groups, follow these steps:
