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.

Bootstrap Microcode Update Requirements for the G06.25

RVU

The disk and tape bootstrap programs (T8494) are unchanged in G06.25. A new disk

bootstrap program (T8494AAA) became available in G06.06. Revive your mirrored disk

as soon as possible after performing a system load.

Updating Firmware

Updateable firmware exists in many of the components in your system, such as:

•

PMFs and IOMFs

•

ServerNet LAN and WAN adapters

•

ServerNet device adapters

•

ServerNet Switch (6770) and ServerNet Switch (6780)

•

IOAM Maintenance Entity (See your service provider for more information.)

You can perform many firmware updates manually using TSM or OSM, but some can

be performed with SCF or by following TSM or OSM-guided procedures. Only OSM

supports ServerNet switch (6780) and the IOAM components.

Note. Always check Scout for the most recent updateable firmware.
