8.1.5 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.
