Undo a wrongly issued command.
If you issue the member command in zone configuration submode, you can undo the results:
switch(config)# zone name test vsan 1
switch(config-zone)# member pwwn 12:12:12:12:12:12:12:12
switch(config-zone)# no member pwwn 12:12:12:12:12:12:12:12
WARNING: Zone is empty. Deleting zone test. Exit the submode.
switch(config-zone)#
Delete a created facility.
If you want to delete a zone that you created:
switch(config)# zone name test vsan 1
switch(config-zone)# exit
switch(config)# no zone name test vsan 1
switch(config)#
You cannot delete a zone facility called test while residing in it. You must first exit the zone
configuration submode and return to configuration mode.
Revert to the default value.
If you issue the zone merge-control restrict vsan command, you can undo the results:
switch(config)# zone zone merge-control restrict vsan 10
switch(config)# no zone merge-control restrict vsan 10
switch(config)#
You can create the configuration for the switch interactively by issuing commands at the CLI
prompt.
You can create an ASCII file containing a switch configuration and then load this file on the required
system. You can then use the CLI to edit and activate the file (see the
Files" section on page 8-1).
