Admin Domain management for physical fabric administrators
NOTE
This section is for physical fabric administrators who are managing Admin Domains.
The ad command follows a batched-transaction model, which means that changes to the Admin
Domain configuration occur in the transaction buffer.
An Admin Domain configuration can exist in several places:
• Effective configuration -- The Admin Domain configuration that is currently in effect.
• Defined configuration -- The Admin Domain configuration that is saved in flash memory. There might
be differences between the effective configuration and the defined configuration.
• Transaction buffer -- The Admin Domain configuration that is in the current transaction buffer and has
not yet been saved or canceled.
How you end the transaction determines the disposition of the Admin Domain configuration in the
transaction buffer. The following commands end the Admin Domain transaction:
ad --save Saves the changes in the transaction buffer to the defined configuration in persistent storage and
propagates the defined configuration to all switches in the fabric. Note that for delete and clear
operations, if one or more of the deleted Admin Domains are in the effective configuration, you
cannot use --save, but must use --apply instead.
ad --apply Saves the changes to the defined configuration in persistent storage and enforces the defined
configuration on all switches in the fabric, replacing the effective configuration.
ad --transabort Aborts the transaction and clears the transaction buffer. The effective and defined configurations
remain unchanged.
You can enter the ad --transshow command at any time to display the ID of the current Admin Domain
transaction.
Setting the default zoning mode for Admin Domains
To begin implementing an Admin Domain structure within your SAN, you must first set the default
zoning mode to No Access. You must be in AD0 to change the default zoning mode.
1. Log in to the switch with the appropriate RBAC role.
2. Ensure you are in the AD0 context by entering the ad --show command to determine the current
Admin Domain.
If necessary, switch to the AD0 context by entering the ad --select 0 command.
3. Set the default zoning mode to No Access, as described in Setting the default zoning mode on page
319.
