HP StorageWorks Fabric OS 6.2 administrator guide (5697-0016, May 2009)

Fabric OS 6.2 administrator guide 531
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 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 stand-alone 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 Fabric OS versions listed below that support
the addressing mode:
• HP StorageWorks SAN Switch 2/8-EL and HP StorageWorks SAN Switch 2/16—3.1.2 or later
• HP StorageWorks SAN Switch 2/8V, HP StorageWorks SAN Switch 2/16V, HP StorageWorks SAN
Switch 2/32, HP StorageWorks Core Switch 2/64, HP StorageWorks SAN Director 2/128—5.3.0
or later
• Brocade 4Gb SAN Switch for HP p-Class BladeSystem—5.0.0 or later
• HP StorageWorks 4/8 and 4/16 SAN Switches, HP StorageWorks 4/256 SAN Director—5.3.0 or
later
• HP StorageWorks 4/64 SAN Switch, HP StorageWorks 400 Multi-Protocol Router or HP
StorageWorks 4/256 SAN Director with a B-Series Multi-Protocol Router Blade—5.3.0 or later
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. Enter the switchDisable command to disable the switch.
4. Enter 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 steps 2 through 7 for the remaining switches in the fabric.
9. Enter 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 that the fabric has fully
reconverged. Each switch can communicate with other switches in the fabric and no segmentation has
occurred.
11. Enter 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 necessary to do this only once per fabric;
the zoning update automatically propagates to all switches.
