PIDs and PID binding overview

Virtual Fabric considerations
WWN-base PID assignment is disabled by default and is supported in the default switch on a
Brocade DCX and DCX-4S. This feature is not supported on application blades such as the
FS8-18
,
FX8-24
, and the
FCOE10-24
. The total number of ports in the default switch must be 256 or less.
When the WWN-base PID assignment feature is enabled and a new blade is plugged into the
chassis, the ports for which the area is not available are disabled.
NPIV
If any NPIV devices have static PIDs configured and the acquired area is not the same as the one
being requested, the FDISC coming from that device is rejected and the error is noted in the
RASlog.
If the NPIV device has Dynamic Persistent PID set, the same AL_PA value in the PID is used. This
guarantees NPIV devices get the same PID across reboots and AL_PAs assigned for the device do
not depend on the order in which the devices come up. Refer to
Chapter 13, “Administering NPIV”
for more information on NPIV.
Enabling automatic PID assignment
NOTE
To activate the WWN-based PID assignment, you do not need to disable the switch.
1. Connect to the switch and log in using an account assigned to the admin role.
2. Enter the configure command.
3. At the Fabric Parameters prompt, type y
4. At the WWN Based persistent PID prompt, type y
5. Press Enter to bypass the remaining prompts without changing them.
Example of activating PID assignments
Configure...
Fabric parameters (yes, y, no, n): [no] y
WWN Based persistent PID (yes, y, no, n): [no] y
System services (yes, y, no, n): [no]
ssl attributes (yes, y, no, n): [no]
rpcd attributes (yes, y, no, n): [no]
cfgload attributes (yes, y, no, n): [no]
webtools attributes (yes, y, no, n): [no]
Custom attributes (yes, y, no, n): [no]
system attributes (yes, y, no, n): [no]
Assigning a static PID
1. Connect to the switch and log in using an account assigned to the admin role.
2. Enter the wwnAddress -bind command to assign a 16-bit PID to a given WWN.
