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 (11iv2 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 FR4-18i 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. 7. Respond to the remaining prompts or press Ctrl-d to accept the remaining settings without responding to all the prompts. 8. Repeat step 2 through step 7 for the remaining switches in the fabric. 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] BB credit: (1..27) [16] 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. 11. 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.
