Changing to Extended Edge PID Format

Example
Changing to Extended Edge PID Format
In rare cases, you might be affected by the presence in the fabric of drivers that rely on static binding to
the dynamically assigned PID; for example, you might be installing a switch running Fabric OS v4.2.0
into a fabric consisting solely of Fabric OS v2.6.2 and later/v3.1.2 and later switches. In these cases, if
you absolutely cannot reboot the affected servers when you upgrade your switches, you can choose
Extended Edge PID format. It uses the same PID mapping for the first 16 ports and can support switches
and directors with higher port counts. However, because Extended Edge format only supports 128 ports
per domain, its use can lead to port addressing issues in directors.
Use the following procedure only if your fabric contains devices that are bound statically and you
cannot reboot the host.
1. Determine if the current switch firmware versions meet the minimum supported version levels.
Table A-3 lists the earliest Fabric OS version levels that support Extended Edge PID format. Use
this table to determine if you need to upgrade the firmware in the switches in your fabric before you
change the PID format.
2. Update switch firmware as necessary.
a. Use the fabricShow command to verify the total number of switches in the fabric.
b. Download the correct firmware version to each switch as necessary.
c. Reboot all switches.
