Hp/Ux Procedure For Updating The Core Switch Pid Format - HP StorageWorks SAN Switch 2/32 Installation Manual

5. One at a time, re-enable the switches in the updated fabric. In a core/edge
network, enable the core switches first.
6. Once the fabric re-converges, type cfgEnable myZoningCfg, (where
myZoningCfg is the name of your zone configuration). Press Enter to update
zoning.
NOTE: This does not change the definition of zones in the fabric, but causes the lowest tables
in the zoning database to update with the new Core Switch PID format.
7. Repeat steps 3 through 6 for all fabrics in the SAN.
8. Bring the devices online in the order appropriate to the SAN. This usually
involves starting up the storage arrays first, and the hosts last.
9. For any devices manually bound by PID, bring the device back online, but do not
start applications. Update their bindings and reboot again if necessary. This may
involve changing them to the new PIDs, or may (preferably) involve changing to
WWN binding.
10. For any devices automatically bound by PID, reboot the device to rebuild the
device tree. (Some operating systems require a special command to do this. E.g.
"boot –r" in Solaris.)
11. For devices that do not bind by PID or have had their PID binding updated, bring
them back up and resume I/O.
12. Verify that all I/O has resumed correctly.
NOTE: Migrating from manual PID binding (e.g. persistent binding on an HBA) to manual WWN
binding and/or upgrading drivers to versions that do not bind by PID can often be done before
setting the core PID format. This can be advantageous, as it prevents the update process from
having as many variables.
IMPORTANT: Once the switch PID format is set, it is stored in the flash memory of the switch
and it is NOT necessary to set it again during subsequent firmware upgrades.

HP/UX Procedure for Updating the Core Switch PID Format

Use these procedures for updating the Core Switch PID format in an HP/UX
environment.
1. Backup all data. Verify backups.
2. If you are not using multi-pathing software, stop all I/O going to all volumes
connected through the switch/fabric to be updated.
