Evaluating the Fabric
A
eliminate host reboots, and second to minimize the need for a host reboot in the future.
Evaluating the Fabric
In addition to this section, refer to the Brocade SilkWorm Design, Deployment, and Management Guide
for information on evaluating the fabric.
If there is the possibility that your fabric contains host devices with static PID bindings, you should
evaluate the fabric to:
• Find any devices that bind to PIDs
• Determine how each device driver will respond to the PID format change
Table A-2 PID Format Recommendations For Adding New Switches
Existing Fabric OS
Versions; PID Format
Switch to be
Added
Recommendations (in Order of Preference)
v2.6.2 and later/v3.1.2 and later;
Native PID
v2.6.2 and
later/v3.1.2
and later
1. Use Native PID format for new switch
Host reboot is not required.
2. Convert existing fabric to Core PID format, upgrading the version
of Fabric OS, if necessary. Set Core PID format for new switch.
Host reboot is required.
3. If devices are bound statically and it is not possible to reboot,
convert existing fabric to Extended Edge PID format, upgrading
the version of Fabric OS, if necessary. Use Extended Edge PID
format for new switch
Host reboot is not required.
v4.2.0 and
later
1. Convert existing fabric to Core PID format, upgrading the version
of Fabric OS, if necessary. Set Core PID format for new switch.
Host reboot is required.
2. If devices are bound statically and it is not possible to reboot,
convert existing fabric to Extended Edge PID format, upgrading
the version of Fabric OS, if necessary. Use Extended Edge PID
format for new switch
