AIX Procedure for Updating the Core Switch PID Format
Use these procedures for updating the Core Switch PID format in an AIX
environment.
1. Back up 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 or fabric to be updated.
3. If you are not using multi-pathing software, varyoff the volume groups. Type,
varyoffvg datavg
4. If you are not using multi-pathing software, unmount the volumes from their
mount points using umount. For example:
umount /mnt/jbod
5. If you are using multi-pathing software, use that software to remove one
fabric's devices from its configuration.
6. Remove the device entries for the fabric you are migrating. For example, if the
HBA for that fabric is fcs0, execute the command:
rmdev -Rdl fcs0
7. Login into each switch in the fabric.
8. Issue the switchDisable command.
9. Issue the configure command. Change the Core Switch PID Format to 1.
