System configuration parameters 3 4. Click Apply. Performing a reboot To reboot the CP and execute the normal power-on booting sequence, perform the following steps. 1. Open the Switch Administration window as described in "Opening the Switch Administration window" on page 31. 2. Click Reboot. 3. On the Reboot Confirmation window, click Yes to continue. 4. Click Apply. System configuration parameters You must disable the switch before you can configure fabric parameters. You can change the following system configuration parameters: • Switch fabric settings • Virtual channel settings • Arbitrated loop parameters • System services • Signed firmware WWN-based Persistent PID assignment WWN-based PID assignment allows you to configure a PID persistently using a device's WWN. When the device logs into the switch, the PID is bound to the device WWN. If the device is moved to another port in the same switch, or a new blade is hot plugged, the device receives the same PID (area) at its next login. For information on configuring WWN-based PID assignment, refer to "Configuring fabric settings" on page 40. This feature is deactivated by default. When the feature is enabled, bindings are created dynamically; as new devices log in, they automatically enter the WWN-based PID database. The bindings exist until you explicitly unbind the mappings through the CLI or change to a different addressing mode. If there are any existing devices when you enable the feature, you must manually enter the WWN-based PID assignments through the CLI. Once WWN-based PID assignment is enabled you must manually enter the WWN-based PID assignments through the CLI for any existing devices. Any new devices logging in are automatically entered in the WWN-based PID database. Current WWN-based PID bindings are cleared when you change to a different addressing mode. PID assignments are supported for a maximum of 4096 devices; this includes both point-to-point and NPIV devices. The number of point-to-point devices supported depends directly on the areas available. For example, 448 are available on an enterprise-class platform and 256 are available on switches. When the number of entries in the WWN-based PID database reaches the number 4096 or areas are used up, the oldest unused entry is purged from the database to free up the reserved area for the new FLOGI. Refer to Table 7 for complete information. Web Tools Administrator's Guide 39 53-1002756-01

WWN-based Persistent PID assignment
WWN-based PID assignment allows you to configure a PID persistently using a device’s WWN.
When the device logs into the switch, the PID is bound to the device WWN. If the device is moved to
another port in the same switch, or a new blade is hot plugged, the device receives the same PID
(area) at its next login. For information on configuring WWN-based PID assignment, refer to
“Configuring fabric settings”
on page 40.
This feature is deactivated by default. When the feature is enabled, bindings are created
dynamically; as new devices log in, they automatically enter the WWN-based PID database. The
bindings exist until you explicitly unbind the mappings through the CLI or change to a different
addressing mode. If there are any existing devices when you enable the feature, you must manually
enter the WWN-based PID assignments through the CLI.
Once WWN-based PID assignment is enabled you must manually enter the WWN-based PID
assignments through the CLI for any existing devices. Any new devices logging in are automatically
entered in the WWN-based PID database. Current WWN-based PID bindings are cleared when you
change to a different addressing mode.
PID assignments are supported for a maximum of 4096 devices; this includes both point-to-point
and NPIV devices. The number of point-to-point devices supported depends directly on the areas
available. For example, 448 are available on an enterprise-class platform and 256 are available on
switches. When the number of entries in the WWN-based PID database reaches the number 4096
or areas are used up, the oldest unused entry is purged from the database to free up the reserved
area for the new FLOGI. Refer to
Table 7
