wwnAddress

Binds an FC Port ID to a device WWN.

Synopsis wwnaddress --bind [WWN] [PID]

wwnaddress --unbind [WWN]

wwnaddress --show

wwnaddress --findPID [WWN]

wwnaddress --help

Description Use this command to manage address assignments for a given device world wide name. The allocation of a PID to

a specified device WWN supports the persistence of the PID based on the WWN of the device to which the PID is

bound. If the PID is not bound to a device WWN, the device can get the same or a different PID irrespective of

which port it logs in to a given switch partition.

This command fails under any of the following conditions:

• The PID is currently bound to another port through port address binding. Use portaddress --unbind to free up

the PID.

• The WWN is already bound with a different PID, or the PID is bound to another WWN. Use wwnaddress

--unbind to remove the PID-WWN binding.

• There is no space left in the WWN-PID table for an additional entry. Use wwnaddress --unbind to free up

space in the table.

The command provides a --show option that displays the currently bound address for all WWNs. Alternately, you

can use the --findPID option to display the PID currently bound to a specified WWN.

Notes Dynamic Area Mode and WWN-Based persistent PID must be enabled on the switch before you can assign an

address with this command. Refer to configure for more information.

This command is supported only on the Brocade DCX and on the DCX-4S.

The execution of this command is subject to Virtual Fabric restrictions that may be in place. Refer to "Using Fabric

OS Commands" and "Command Availability" for details.

Operands This command has the following operands:

--bind

Assigns the lower two bytes of the Fibre Channel address to the specified WWN.

WWN

Specifies the WWN for the device to which the PID should be assigned.

PID

Specifies the PID (the lower 16 bits of the address excluding the domain part) in

hexadecimal format to be bound to the device WWN. Note that only the upper 10 bits of the

PID can be used for a unique route. Therefore, not all addresses in the 16-bit range are

available.
