8 Updating Processor Boot Code
Processor boot code controls device boot and power-on diagnostic functions.
This section describes the two common methods for updating the processor boot code
and how to use either the OSM Service Connection or TSM Service Application to
update the processor boot code for each PMF CRU in your system. See Table 8-1.
With the introduction of the G06.24 RVU and the new boot code firmware (T7892ABD)
needed for the S88000 processor, potential system problems can result if you upgrade
the boot millicode and you:
•
Select the explicit online command option from either the Resource Type menu in
TSM or the Action menu in OSM
•
Do not have the G06.24 or later OSM and their prerequisite SPRs or TSM SPRs
installed and started. (See HS02865, OPN T7892G07 ABD Online Boot Code
Upgrade Warning.) For a list of OSM SPRs for G06.24, G06.25, G06.26, and
G06.27, see OSM Server and Client Compatibility SPRs on page 3-9.

Processor boot code is the processor
millicode that is used to load, reload, and
dump each processor.
Always check Scout for the latest processor boot code SPRs (T8461 and T7892).
Note. Update processor boot code only:
•
If instructed to do so by DSM/SCM
•
If you are not replacing the PMF CRUs in your system while migrating to the G06.27 RVU
Caution. Before using the online boot code option for upgrading boot millicode to T7892ABD
or later, you must install and configure the G06.24 or later version of either TSM server
(T7945ABN) or all OSM server-based SPRs (along with their prerequisites). Otherwise, a
processor halt occurs.
Read HS02865 for background information and recommended upgrade options. Instead of
using Hard Reset as one of the options described in the Hotstuff, use Reset instead, or
perform a Start System from the TSM or OSM Low-Level Link as described in the Hotstuff and
Section 11, Loading the G06.27 RVU
