Basic Procedure For Changing The Pid Format - HP A7533A - Brocade 4Gb SAN Switch Base Administrator's Manual

In some cases, device drivers allow you to specify static PID binding. In these cases, such devices must be
identified and their PID binding should be changed to WWN binding.
The following sections contain a basic procedure that summarizes the steps necessary to perform PID
format changes without disrupting the fabric, and special procedures for HP-UX (1 1iv2 or earlier only) and
AIX.

Basic procedure for changing the PID format

This process should be executed as part of the overall online or offline update process. However, it can be
implemented in a standalone manner on a non-production fabric, or a switch that has not yet joined a
fabric.
1. Ensure that all switches in the fabric are running one of the minimum Fabric OS versions listed below
that support the addressing mode:
• SAN Switch 2/8EL and SAN Switch 2/16—3.1.2
• Brocade 4 Gb SAN Switch for p-Class BladeSystem—5.0.0
• SAN Switch 2/8V, SAN Switch 2/16V, SAN Switch 2/32, Core Switch 2/64, SAN Director
2/128, Brocade 4/8 SAN Switch, 4/16 SAN Switch, 4/256 SAN Director, 4/64 SAN Switch,
400 Multi-protocol Router or 4/256 SAN Director with an FR4- 1 8i blade—5.3.0
NOTE: All switches running any version of Fabric OS 4.0.0 and later are shipped with the Core Switch
PID Format enabled, so it is not necessary to perform the PID format change on these switches.
2. Telnet into one of the switches in the fabric.
3. Issue the switchDisable command to disable the switch.
4. Issue the configure command (the configure prompts display sequentially).
5. Enter y after the Fabric parameters prompt.
6. Enter 1 at the Core Switch PID Format prompt.
Respond to the remaining prompts or press Ctrl-d to accept the remaining settings without responding
7.
to all the prompts.
8. Repeat step 2
9. Issue the switchEnable command to re-enable the switch. For example:
switch:admin> switchdisable
switch:admin> configure
Configure...
Fabric parameters (yes, y, no, n): [no] yes
Domain: (1..239) [1]
R_A_TOV: (4000..120000) [10000]
E_D_TOV: (1000..5000) [2000]
Data field size: (256..2112) [2112]
Sequence Level Switching: (0..1) [0]
Disable Device Probing: (0..1) [0]
Suppress Class F Traffic: (0..1) [0]
SYNC IO mode: (0..1) [0]
Core Switch PID Format: (0..2) [0] 1
Per-frame Route Priority: (0..1) [0]
Long Distance Fabric: (0..1) [0]

10. After all switches are updated to use the new PID format and re-enabled, verify the fabric has fully
reconverged. Each switch can communicate with other switches in the fabric and no segmentation has
occurred.
1 1. Issue the cfgEnable active_config_name command on one of the switches in the fabric to
update zoning to use the new PID form.
This does not change the definition of zones in the fabric; it causes the lowest level tables in the
zoning database to be updated with the new PID format setting. It is only necessary to do this once
per fabric; the zoning update automatically propagates to all switches.
At this point, all switches in the fabric are operating in the new addressing mode.
through step 7 for the remaining switches in the fabric.
