Backing up and restoring the nonvolatile variables

The Extensible Firmware Interface (EFI) in the xSeries 450 stores its variables with
nonvolatile attributes in NVRAM on the Remote Supervisor Adapter. Before you
remove or replace the Remote Supervisor Adapter or clear the NVRAM, be sure to
make a backup copy of the nonvolatile EFI variables. After you install a new
Remote Supervisor Adapter, you must restore the EFI variables previously stored in
NVRAM. The EFI variables stored in NVRAM on the Remote Supervisor Adapter
include the following:
v Console definitions
v Boot options / Drivers
v Boot order / Timeout
You can use the xSeries 450 Backup and Restore utilities to backup or restore the
nonvolatile EFI variables stored in NVRAM.
