Zone configurations

You can use the cfgSize command to check both the maximum available size and the currently
saved size on all switches. If you think you are approaching the maximum, you can save a partially
completed zone configuration and use the cfgSize command to determine the remaining space.
The cfgSize command reports the maximum available size on the current switch only. It cannot
determine the maximum available size on other switches in the fabric.
The minimum zone database size is 4 bytes, even if the zone database is empty.
For important considerations for managing zoning in a fabric, and more details about the maximum
zone database size for each version of the Fabric OS, see “Zone database size” on page 254.
If you create or make changes to a zone configuration, you must enable the configuration for the
changes to take effect.
Creating a zone configuration
1. Connect to the switch and log in using an account with admin permissions.
2. Enter the cfgCreate command, using the following syntax:
cfgcreate "cfgname", "member[; member...]"
3. Enter the cfgSave command to save the change to the defined configuration.
The cfgSave command ends and commits the current zoning transaction buffer to nonvolatile
memory. If a transaction is open on a different switch in the fabric when this command is run,
the transaction on the other switch is automatically aborted. A message displays on the other
switches to indicate that the transaction was aborted.
Example
switch:admin> cfgcreate "NEW_cfg", "purplezone; bluezone; greenzone"
switch:admin> cfgsave
You are about to save the Defined zoning configuration. This
action will only save the changes on the 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
Adding zones (members) to a zone configuration
1. Connect to the switch and log in using an account with admin permissions.
2. Enter the cfgAdd command, using the following syntax:
cfgadd "cfgname", "member[; member...]"
3. Enter the cfgSave command to save the change to the defined configuration.
The cfgSave command ends and commits the current zoning transaction buffer to nonvolatile
memory. If a transaction is open on a different switch in the fabric when this command is run,
the transaction on the other switch is automatically aborted. A message displays on the other
switches to indicate that the transaction was aborted.
