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 prede
fi
ned 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 simpli
fi
es 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
speci
fi
c port, even if the port is currently of
fl
ine.
•
licensePort –release portnum
removes a license from a port.
•
portCfgPersistentDisable
blocks a speci
fi
c port from future assignments.
•
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 Brocade 4/24 SAN Switch:
