You are about to save the Defined zoning configuration. This
action will only save the changes on Defined configuration.
Any changes made on the Effective configuration will not
take effect until it is re-enabled. Until the Effective
configuration is re-enabled, merging new switches into the
fabric is not recommended and may cause unpredictable
results with the potential of mismatched Effective Zoning
configurations.
Do you want to save Defined zoning configuration only? (yes, y, no, n): [no] y

Viewing the current default zone access mode
1. Connect to the switch and log in as admin.
2. Enter the defZone
--show command.
NOTE
If you perform a firmware download of an older release, then the current default zone access state
will appear as it did prior to the download. For example, if the default zoning mode was No Access
before the download, it will remain as No Access afterward.
Zone database size
The maximum size of a zone database is the upper limit for the defined configuration, and it is
determined by the amount of flash memory available for storing the defined configuration.
Use the cfgSize command to display the zone database size.
The supported maximum zone database size is 1 MB.
Virtual Fabric considerations: If Virtual Fabrics is enabled, the sum of the zone database sizes on
all of the logical fabrics must not exceed the maximum size allowed for the chassis (1 MB). The
maximum size limit is enforced per-partition, but is not enforced chassis-wide. If the chassis size
limit is exceeded, you are not informed of this and unpredictable behavior might occur. It is your
responsibility to keep track of the chassis-wide zone database size.
ATTENTION
In a fabric with some switches running Fabric OS 7.0.0 or later and some switches running Fabric OS
versions earlier than 7.0.0, if you execute the cfgSave or cfgEnable command from a pre-7.0.0
switch, a zone database size of 128 KB is enforced.
To avoid this problem, use the switch with the highest Fabric OS version to perform zoning tasks, as
described in “Best practices for zoning” on page 246. Alternatively make sure that your pre-7.0.0
switches are upgraded with the latest patch release.
