Updating Processor Boot Code

Even if you are not installing new S88000s, if you try to update to T7892ABD boot
millicode for other NonStop S-series processors, such as S74000, S78000, and so
forth, a processor halt occurs.
As documented in HS02865, there are at least three strategies for updating processor
boot code firmware, with subsequent methods for reloading the processors. See
HS02865 for further details.
This section combines the three Hotstuff strategies into two major methods:
•
Method 1: Using G06.24 or Later OSM or TSM SPRs, Update Processor Boot
Code Using the Explicit Online Option on page 9-4
To use this method, you must have at least the G06.24 OSM or TSM SPRs
installed on your client and server. In this case, you can select the explicit online
boot code update available in either TSM or OSM. Note that if you are on an
S7000, the online update option does not appear.
It is possible to update OSM and TSM SPRs to the latest versions and still decide,
based on previous adhered-to practices, not to update the processor millicode
using the explicit online option. Follow the steps described in Method 2.
•
Method 2: Using Your Current Pre-G06.24 OSM or TSM SPRs, Update the
Processor Boot Code and Issue a Reset Action or Equivalent on page 9-10
To use this method, you must have down-rev G06.24 OSM or TSM SPRs installed
on your client and server. If this is the case, you cannot use the explicit online boot
code update. It will cause a processor halt.
It is possible to update your OSM and TSM SPRs to the latest versions and still
decide not to update the processor millicode using the explicit online option
available in either TSM or OSM. In this case, you must issue a Reset action or a
Reload using Start System during the system load procedure. See Section 12,
Loading the G06.31 RVU.
