Remove the original (outdated) entry. The proper usage for this command is rmsf -a -v . For example: rmsf -a -v /dev/dsk/c65t8d0 18. Enter 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 Class I H/W Path Driver S/W State H/W Type Description disk 0 0/0/1/1.2.0 adisk CLAIMED DEVICE SEAGATE ST39204LC /dev/dsk/clt2d0 /dev/rdsk/c1t2d0 disk 1 0/0/2/1.2.0 adisk CLAIMED DEVICE HP DVD-ROM 304 /dev/dsk/c3t2d0 /dev/rdsk/c3t2d0 disk 319 0/4/0/0.1.2.255.14.8.0 19.

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. Verify backups. 2. Perform the appropriate actions based on whether you using or not using multipathing software: • If you are not using multipathing software, stop all I/O going to all volumes connected through the switch or fabric to be updated. • If you are not using multipathing software, vary the volume groups offline. The command usage is varyoffvg . For example: varyoffvg datavg 3. Perform the appropriate actions based on whether you using or not using multipathing software: • If you are not using multipathing software, unmount the volumes from their mount points using umount. The command usage is umount . For example: umount /mnt/jbod • If you are using multipathing software, use that software to remove one fabric's devices from its configuration. 4. 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 5. Connect to each switch in the fabric. 6. Enter the switchDisable command. 7. Enter the configure command and change the Core Switch PID Format to 1. 8. Enter the configEnable [effective_zone_configuration] command. For example: configenable my_config 9. Enter the switchEnable command. Enable the core switches first, and then the edges. Fabric OS 6.2 administrator guide 533
