Using Dynamic P
orts On Demand (DPOD)
In the past, Po
rts On Demand (POD) functionality was static. A preset group of ports
were individu
ally 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 purc hased ports.
In summary, the DPOD feature simplifies port management by:
• automatical
ly 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 i nitial P OD 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 specificportfromfutureassignments.
• licensePort -show displays an overview of the POD license status and port
assignments.
The following shows examples of the licensePort -show command for a Brocade
4/12 SAN Switch and a Br ocade 4/24 SAN Switch:
