Recovery from incorrect settings
Certain settings must be correct for successful PXE booting, such as:
• port mode
• VLAN tagging.
If these settings become incorrect, for example because a server is moved to a
different part of the network. PXE booting will then fail.
To correct these settings, you must use the Solarflare Boot Manger GUI utility. (You
cannot use the
sfboot
command line utility, because there is no OS to host it.) This
is possible only in single Physical Function mode.
If multiple Physical Functions have been enabled, the incorrect settings are read ‐
only. In such cases, you must reset the adapter to its default settings (see Default
Adapter Settings on page 387 ). This returns the adapter to a single Physical Function
mode, and removes all VLAN tags. You can then use the Boot Manger to make the
settings that you require.
