534 Configuring the PID format
10. Rebuild the device entries for the affected fabric using the
cfgMgr
command. For example:
cfgmgr –v
This command might take several minutes to complete.
11. Perform the appropriate actions based on whether you using or not using multipathing software:
• If you are not using multipathing software, vary the disk volume groups online. The proper usage
would be
varyonvg <volume_group_name>
. For example:
varyonvg datavg
• If you are not using multipathing software, mount all devices again and restart I/O. For example:
mount /mnt/jbod
12. If you are using multipathing software, reenable the affected path.
13. Repeat all steps for all fabrics.
Swapping port area IDs
If a device that uses port binding is connected to a port that fails, you can use port swapping to make
another physical port use the same PID as the failed port. The device can then be plugged into the new
port without the need to reboot the device.
Use the following procedure to swap the port area IDs of two physical switch ports. In order to swap port
area IDs, the port swap feature must be enabled, and both switch ports must be disabled. The swapped
area IDs for the two ports remain persistent across reboots, power cycles, and failovers.
HP StorageWorks 4/256 SAN Director and HP StorageWorks DC SAN Backbone Director and HP
StorageWorks DC04 SAN Director platforms only: You can swap only ports 0 through 15 on the HP
StorageWorks SAN Director 48 Port 4Gb FC blade and HP StorageWorks SAN Director 48 Port 8Gb FC
blade. You cannot swap ports 16 through 47.
1. Connect to the switch and log in as admin.
2. Enable the port swap feature:
portswapenable

portswap slot1/port1 slot2/port2
5. Verify that the port area IDs have been swapped:
portswapshow
Table 102 shows the physical port numbers and the logical area IDs for any swapped ports.
