Compatibility; Firmware Upgrade Considerations; Managing Admin Domains; Understanding The Ad Transaction Model - HP A7533A - Brocade 4Gb SAN Switch Base Administrator's Manual

Compatibility

Admin Domains can be implemented in fabrics with a mix of AD-capable switches and AD-uncapable
switches. The following considerations apply:
• In mixed-fabric configurations, the legacy switches allow unfiltered access to the fabric and its devices;
hence, these legacy switches should be managed by the physical fabric administrator.
• You must zone all ports and devices from legacy switches in the AD0 root zone database.
• If you have legacy switches in your AD-activated fabric, you must ensure that all new AD resources have
enough interconnectivity so that they do not get isolated into subfabrics with a legacy subfabric
interposed in the middle, as shown in
AD-capable fabric

Isolated subfabrics

Firmware upgrade considerations

The following scenario is for enterprise-class products only:
• If the primary and secondary CPs are running pre-Fabric OS 5.2.0 and HA state is "synchronized", and
if firmwareDownload is used to upgrade one CP alone (using the firmwareDownload -s
option), then that CP will run in a non-AD-capable mode (AD creation operations will fail and the local
switch will show up as a non-AD-capable switch in the fabric).

Managing Admin Domains

This section is for physical fabric administrators who are managing Admin Domains. You must be a
physical fabric administrator to perform the tasks in this section.
• "Setting the default zone
• "Creating an Admin
• "Assigning a user to an Admin
• "Activating and deactivating Admin
• "Adding and removing Admin Domain
• "Renaming an Admin
• "Deleting an Admin
• "Deleting all user-defined Admin
• "Validating an Admin Domain member

Understanding the AD transaction model

You use the ad command to perform most of the tasks in this section. This 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.
