Using Dynamic Ports On Demand (DPOD)

In the past, Ports On Demand (POD) functionality was static. A preset group of ports were individually enabled per each POD license. In contrast, the new DPOD functionality does not require a predeﬁned assignment of ports. Port assignment is determined by the total number of ports in use as well as the number of purchased ports.

In summary, the DPOD feature simpliﬁes port management by:

•automatically detecting HBA connected server ports or cabled ports.

•automatically enabling ports

•automatically assigning port licenses

To initiate DPOD, use the licensePort command, as described in DPOD commands.

IMPORTANT:

For the Brocade 4Gb SAN Switch, DPOD works only if the server blade is installed with an HBA present. A server blade that does not have a functioning HBA will not be treated as an active link for the purpose of initial POD port assignment.

DPOD commands

Use the licensePort command to manage dynamic POD assignments with the following options:

•licensePort –reserve portnum reserves a future license assignment for a speciﬁc port, even if the port is currently ofﬂine.

•licensePort –release portnum removes a license from a port.

•portCfgPersistentDisable blocks a speciﬁc port from future assignments.

•licensePort -showdisplays an overview of the POD license status and port assignments.

The following shows examples of the licensePort -showcommand for a Brocade 4/12 SAN Switch and a Brocade 4/24 SAN Switch:
