Updating the Core Switch PID Format 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. 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/fabric to be updated. 3. If you are not using multi-pathing software, unmount the volumes from their mount points using umount. The proper usage would be umount . For example: umount /mnt/jbod 4. If you are using multi-pathing software, use that software to remove one fabric's devices from its configuration. 5. Deactivate the appropriate volume groups using vgchange. The proper usage would be vgchange -a n . For example: vgchange -a n /dev/jbod 6. Make a backup copy of the volume group directory using tar from within /dev. For example: tar -cf /tmp/jbod.tar jbod 7. Export the volume group using vgexport. The proper usage would be vgexport -m . For example: vgexport -m /tmp/jbod_map /dev/jbod 8. Login into each switch in the fabric 9. Issue the command switchDisable. 10. Issue the command configure and change the Core Switch PID Format to 1. 11. Issue the command switchEnable. Enable the core switches first, then the edge switches. 12. Once you have done this to all switches in the fabric and verified that it has re-converged properly, issue the command cfgEnable [effective zone configuration] on one of the switches in that fabric. For example: cfgEnable my_zones 13. Clean the lvmtab file by using the command vgscan. SAN Switch 2/32 Installation Guide 97

SAN Switch 2/32 Installation Guide
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.
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/fabric to be updated.
3.
If you are not using multi-pathing software, unmount the volumes from their
mount points using umount. The proper usage would be umount <mount
point>. For example:
umount /mnt/jbod
4.
If you are using multi-pathing software, use that software to remove one
fabric’s devices from its configuration.
5.
Deactivate the appropriate volume groups using vgchange. The proper usage
would be vgchange –a n <path to volume group>. For example:
vgchange –a n /dev/jbod
6.
Make a backup copy of the volume group directory using tar from within /dev.
For example:
tar –cf /tmp/jbod.tar jbod
7.
Export the volume group using vgexport. The proper usage would be vgexport
–m <map file> <path to volume group>. For example:
vgexport –m /tmp/jbod_map /dev/jbod
8.
Login into each switch in the fabric
9.
Issue the command
switchDisable
.
10.
Issue the command
configure
and change the Core Switch PID Format to
1.
11.
Issue the command
switchEnable
. Enable the core switches first, then the
edge switches.
12.
Once you have done this to all switches in the fabric and verified that it has
re-converged properly, issue the command
cfgEnable
[effective zone
configuration] on one of the switches in that fabric. For example:
cfgEnable my_zones
13.
Clean the lvmtab file by using the command
vgscan
.
