Three Steps of the Firmware Update
The firmware update for the server has three steps (XCP import, update,
application) as explained below.
1. XCP import
Storing the obtained XCP data in this system is called "XCP import." The system
administrator or a field engineer obtains the XCP data files from the network or
external media (CD-ROM, DVD-ROM, or flash drive), then he or she imports the
data file using an XSCF console from a client (personal computer or workstation)
connected to the server.
Simply importing XCP does not update the firmware that is running. Also, the
XCP file is imported only by the versions number of one generation.
2. Update
Writing the XSCF and OpenBoot PROM firmware programs that were imported
in step 1 to flash memory in this system is called "update." Performing the
download writes the XSCF firmware to the flash memory of the XSCF Unit, resets
the XSCF, applies the XSCF firmware, and completes the firmware update. The
OpenBoot PROM firmware is written to the flash memory on the system board.
The OpenBoot PROM firmware is applied during a reboot.
Caution – IMPORTANT – Even if this system is divided into domains, the update
is performed to newly write the OpenBoot PROM firmware to the flash memory on
the XSB of every domain. However, unlike the XSCF firmware, just the download of
this firmware does not update the OpenBoot PROM firmware that is running. To
complete updating the OpenBoot PROM firmware in the target domain, the domain
must be rebooted.
3. Application
Making the firmware written to flash memory in this system actually usable is
called "application."
Note – The number of domains that can be updated (application) is one or more. To
apply the OpenBoot PROM firmware in the target domain, be sure to reboot the
domain for firmware application.
