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 4.2.0 into
a fabric consisting solely of Fabric OS 2.6.2 and later and Fabric OS 3.1.2 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 supports only
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 whether the current switch firmware versions meet the minimum supported version levels.
Table 47 lists the earliest Fabric OS version levels that support Extended Edge PID format. Use this table
to determine whether you need to upgrade the firmware in the switches in your fabric before you
change the PID format. HP recommends that you download the latest firmware; to download firmware,
see "Obtaining and unzipping

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.
d. Verify that the switches form a single fabric and that all domain IDs do not change after forming
the fabric.
e. Verify that the number of switches is the same.
Disable the switch by entering the switchDisable command.
