Managing Microcode and Firmware
•
Rename the files that currently have actual file names to fabricated names.
These files become obsolete when the new files are renamed.
•
Rename the new files, which have fabricated names, to their actual names.
After ZPHIRNM has completed renaming all OSS and Guardian files, it will run
ZMODGP if it exists in the SYSnn being activated and if:
°
The configuration being activated contains a ZCNFDEFS TSV
°
One or more of the ZcccGP files in the ZCNFDEFS TSV are new or
changed (as compared to the last configuration activated). If none of the
ZcccGP files change, ZMODGP is not run.
ZMODGP is a TACL script that makes changes to the generic-process definitions
in the system configuration database. When you use the ZMODGP script, you do
not need to hard code new generic process definitions directly into the $ZCDB
process (T6586, Configuration Services).
Starting in G06.26, ZPHIRNM copies a new dial-out report SWCONFIG from
SYSnn being activated to ZDSMSCM subvolume. ZPHIRNM updates the
SWCONFIG report with the date and time of activation and generates a TSM (or
OSM) software configuration incident report. In the PREVIEW mode, ZPHIRNM
does not perform any dial-out related activities. Preparing the dial-out report file
SWCONFIG is displayed in the Planner Interface (PI).
Managing Microcode and Firmware
You must ensure that all microcode and firmware within your system is managed
properly, updating it as necessary when new versions become available. Failure to do
so can result in a wide range of system problems, from intermittent faults to partial or
complete system outages.
Updating Disk and Tape Bootstrap Microcode
When you perform a system load, a disk or tape bootstrap microcode file is used by
the system during its startup process. You must use the SCF program to update these
files as new versions become available.
The SCF CONTROL DISK, REPLACEBOOT command converts a work file
(SYSDISC) containing the new disk bootstrap loader and controller microcode to a
special format and then writes it into space reserved for bootstrap microcode on the
system disk.
Note. Always check Scout for the most recent updatable firmware.
