HP Brocade 4Gb SAN Switch for HP BladeSystem p-Class - Manual (Page 214)

214 Configuring the PID format
• Relocating devices to new ports or new switches (that is, for Add, Move, Change type operations)
• Updating the core PID format
• Using hot spare switch ports to deal with failures
In every case where devices employ static PID binding, any such procedure becomes difficult or
impossible to execute without downtime.
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 and AIX.
Basic procedure
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 Fabric OS versions that support the addressing
mode. HP recommends that you use v2.6.2 for HP StorageWorks 1 GB switches; v3.1.2 for SAN
Switch 2/8-EL and SAN Switch 2/16; v4.2.0 for HP StorageWorks 2GB switches, SAN Switch
2/8V, SAN Switch 2/16V, SAN Switch 2/32, Core Switch 2/64 and SAN Director 2/128.
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. Disable the switch by issuing the
switchdisable
command.
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. Complete the remaining prompts or press Ctrl+d to accept the remaining settings without completing
all the prompts.
8. Repeat step 2 through step 7 for the remaining switches in the fabric.
9. Reenable the switch by entering the
switchenable
command.
Example:
switch:admin> switchdisable
switch:admin> configure
