Fabric OS Command Reference 1063
53-1001764-01
wwnAddress
2
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 or Admin Domain restrictions that may be in
place. Refer to Chapter 1, "Using Fabric OS Commands" and Appendix A, "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.
--unbind
Removes the WWN-PID binding corresponding to the specified device WWN.
WWN
Specifies the WWN for the device from which to remove the PID binding.
