19. Remove the original (outdated) entry. The proper usage for this command is
rmsf –a –v <path_to_device>. For example:
rmsf –a –v /dev/dsk/c65t8d0
20.Issue the ioscan -funC disk command to validate that the entry has been removed. In this
example, the NO_HW entry is no longer listed:
het46 (HP-50001)> ioscan -funC disk

21.Repeat for all fabrics.
22.Issue the switchEnable command. Enable the core switches first, and then the edges.

AIX procedure for changing the PID format

This procedure is not intended to be comprehensive. It provides a starting point from which a SAN
administrator can develop a site-specific procedure for a device that binds automatically by PID, and
cannot be rebooted due to uptime requirements.
1. Back up all data and verify the backups.
2. If you are not using multipathing software, stop all I/O going to all volumes connected through the
switch or fabric to be updated.
3. If you are not using multipathing software, vary the volume groups offline. The command usage is
varyoffvg <volume_group_name>. For example:
varyoffvg datavg
4. If you are not using multipathing software, unmount the volumes from their mount points using umount.
The command usage is umount <mount_point>. For example:
umount /mnt/jbod
5. If you are using multipathing 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
