This document describes the installation of Licensed Machine Code, which
is sometimes referred to generically as microcode or firmware.
The firmware levels contained in this update are:
The typical time to install this firmware is one hour. The firmware
does not become active when installed and requires a system reboot
to become active. This reboot time will vary depending on the system and
the amount of features installed. This estimate is for an average
system.

Don't be alarmed at the length of this document! For any given download/unpacking/update environment, the process is short. This document describes processes for several environments. One should be suitable for your needs, and these instructions guide you through just the environment you choose.
Once an update to version WIL99071, or later, has been successfully applied, the power controller problem will be completely corrected.
Firmware Update Sequence
When both System and Service Processor firmware are to be updated,
the SYSTEM firmware MUST BE UPDATED FIRST.
Never power OFF the system during the firmware update process!
The update will be incomplete and will fail. Depending
on where in the update process the power was lost, a recovery attempt will
often succeed. One recovery attempt is worthwhile.
Check current Service Processor firmware version before updating.
A good practice is to check the Service Processor firmware version
prior to attempting an update (See
Section 4.0). If you anticipate updating a Service Processor
whose current firmware level is not at least ag980421 you may wish to have
a spare Service Processor card ready in case the update happens to hit
a very small, but critical, timing window and fail.
Once an update to version ag980421, or later, has been successfully applied, the critical timing window, and its hazards, are completely corrected.
Service Processor firmware versions prior to ag980421 have very high update successes. About 5% to 10% of update attempts are exposed to a critical timing window that has been shown to cause update failures which leave the Service Processor's program memory partially empty. A second attempt to update this firmware is worthwhile.
In the event a Service Processor firmware update encounters the critical
window, the update process will either
(a) hang or
(b) give a warning that the update process failed.
(This
warning may be followed by a system reboot.)
In either case, upon reboot, the system will hang with progress code E0FF displayed on the operator panel. At this point, the Service Processor update process should be repeated (once). If this second attempt to update fails, the Service Processor must be replaced.
Use ONLY 7026-H50 Service Processor firmware updates
Ensure that the new Service Processor firmware is an "ag" version such
as ag001220 (00=year, 12=month, 20=day). If you update 7026-H50 systems
with "wc" versions, it will corrupt the Service Processor
firmware.
If you update 7026-H50 systems with "wc" versions, the next power ON
will quickly result in error message 40210014 followed by system shutdown.
Additional error messages (such as 2BA00364, 2BA00367, etc.) may also appear
prior to shutdown, depending on system configuration. Replacing the
Service Processor card is the only recovery solution for the field.
Two methods for reading the firmware levels are described below:
Enter:
lscfg -vp | grep alterable
This command will produce a system configuration report similar to the following.
ROM Level (alterable).......L02113 <== System FW Level ROM Level (non-alterable)...ag010611 ROM Level (alterable).......ag010611 <== Service Processor FW level
The ROM Level (alterable) lines list the levels of the currently
installed firmware. In the above example, the current System firmware
level is L02113, the current Service Processor firmware level is ag010611.
If the right-most five characters (date) of the current System FW level is less than 08295 you should consider installing the update.
If the right-most six characters (date) of the current Service Processor FW level is less than 030603, you should consider installing the update.
If you find the firmware levels are not correct companions, or that they must be updated, proceed to Section 5.0. If the firmware levels are correct companions and no update is needed, installation is complete.
The current System and Service Processor firmware levels can be found under the "Display Configuration" selection on the SMS main menu. The System firmware level is shown under "System Information" on the line "Firmware Level", and the Service Processor firmware level is shown under "Service Processor Information" on the line "ROM Level."
If the right-most five characters (date)of the current System FW level is less than 08295 you should consider installing the update.
If the right-most six characters (date)of the current Service Processor FW level is less than 030603, you should consider installing the update.
When you have read the current firmware levels, exit SMS as directed on the menu screens.
If you find the firmware levels are not correct companions, or that they must be updated, proceed to Section 5.0. If the firmware levels are correct companions and no update is needed, installation is complete.
The current System and Service Processor firmware levels can be found under the "Config" selection on the SMS main menu. The System firmware level is shown under "System Information" on the line "Firmware Level", and the Service Processor firmware level is shown under "Service Processor Information" on the line "ROM Level."
If the right-most five characters (date)of the current System FW level is less than 08295 you should consider installing the update.
If the right-most six characters (date)of the current Service Processor FW level is less than 030603, you should consider installing the update.
When you have read the current FW levels, exit SMS as directed on the menu screens.
If you find the firmware levels are not correct companions, or that they must be updated, proceed to Section 5.0. If the firmware levels are correct companions and no update is needed, installation is complete.

Follow the instructions on this web page. You must read and agree to the license agreement to obtain the firmware packages.
In the drop-down box, choose the entry for your specific machine type and model.
The download choices at that entry are:
Note: In the
instructions that follow are specific AIX commands.
AIX commands are CASE (lower and upper) SENSITIVE, and must
be
entered exactly as shown, including the filenames.
a) Provide a directory on an AIX system to receive the AIX package.
Enter:
mkdir /tmp/fwupdate
Note: If the
directory /tmp/fwupdate already exists,
make sure it is empty before proceeding.
b) Transfer the AIX format file to the /tmp/fwupdate directory
(using "Save as ...").
You will see the filename is 7026H50F.BIN
c) Unpack the file by executing the instructions below.
Enter the commands:
cd /tmp/fwupdate
chmod +x
7026H50F.BIN
./7026H50F.BIN
[Don't overlook the periods (.) in the above command.]
These files will be added to /tmp/fwupdate.
wil08295.img
ag030603.img
If the above procedure was used to transfer files directly to the target system, proceed to Section 6.0 Updating the Firmware.
Otherwise, from the intermediate AIX system, choose one of the following methods for transferring files to the target system.
On the intermediate AIX system,
Enter the commands:
ftp {name
of target system}
{Login with a
valid userid and password}
bin
lcd /tmp/fwupdate
mkdir /tmp/fwupdate
cd /tmp/fwupdate
put wil08295.img
put ag030603.img
quit
Proceed to Section 6.0 Updating the Firmware.
With the diskette loaded in the drive,
Enter the commands:
cd /tmp/fwupdate
ls *.img
| backup -i -v -f/dev/rfd0
This will produce an AIX backup diskette. Label this diskette
"AIX Backup: System (L08295) and SvP (ag030603) FW for IBM 7026-H50".
Proceed to Section 6.0, Updating the Firmware.
If you must use SMS (i.e. the system cannot boot AIX), proceed as follows.
Two 2MB (HD) new or freshly formatted DOS diskettes (or use the AIX dosformat command) are required.
With the first diskette loaded in the drive,
Enter the commands:
doswrite wil08295.img wil08295.img
Label this diskette,
"Image: System (L08295) FW for IBM 7026-H50"
With the second diskette loaded in the drive,
Enter:
doswrite ag030603.img ag030603.img
Label this diskette,
"Image: SvP (ag030603) FW for IBM 7026-H50"
Proceed to Section 6.0 Updating the Firmware.
a) Prepare a directory for receiving the DOS package.
This directory can be in any partition
with 6MB available space.
Executing in such a partition,
called [path] in these instructions
(ex. c:\download),
Enter:
md [path]\fwupdate
Note: If the directory [path]\fwupdate
already exists,
make sure it is empty before proceeding.
b) Transfer the DOS format file to the [path]\fwupdate
directory (using "Save as ...").
You will see the filename is 7026H50F.EXE
c) Unpack the file by executing the instructions below.
Enter the commands:
cd [path]\fwupdate
7026H50F
These files will be added to the fwupdate subdirectory:
26H50F_B.EXE
wil08295.img
ag030603.img
With the diskette loaded in the drive,
Enter the commands:
cd [path]\fwupdate
26H50F_B
Label this diskette,
"AIX Backup: System (L08295) and SvP (ag030603) FW for IBM 7026-H50"
Note:
Any diskette labeled: 'AIX Backup: . . . .' is in a format that can be
used
directly with a computer running AIX as it's operating system. This
diskette cannot be read using PC tools or command line operations.
Proceed to Section 6.0, Updating the Firmware.
Two 2MB (HD) new or freshly formatted DOS diskettes are required.
With the first diskette loaded in the drive,
Enter the commands:
cd [path]\fwupdate
copy wil08295.img
a:
Label this diskette,
"Image: System (L08295) FW for IBM 7026-H50"
With the second diskette loaded in the drive,
Enter:
copy ag030603.img
a:
Label this diskette,
"Image: SvP (ag030603) FW for IBM 7026-H50"
Proceed to Section 6.0 Updating the Firmware.
***
WARNING:
Do not power off the target system at any time before
the update process completes.
***
Note: Checksums can be used to verify files have not been corrupted or altered during transmission.
At the AIX command line, enter:
sum wil08295.img
This command will produce the following output:
31641 1024 wil08295.img
The checksum is -------> 31641
sum ag030603.img
This command will produce the following output:
38407 368 ag030603.img
The checksum is -------> 38407
Two update methods are described below.
This method allows updating either from files already loaded into the target system or from diskettes.
Enter the commands:
cd /usr/lpp/diagnostics/bin
./update_flash
-f /tmp/fwupdate/wil08295.img
[Don't overlook the periods (.) in the above command.]
You will be asked for confirmation to proceed with the firmware update and the required reboot. If you confirm, the system will apply the new firmware, reboot and return to the AIX prompt. This may take one to ten minutes, depending on the configuration of the target system.
At the new AIX prompt, apply the Service Processor firmware update.
Enter the commands:
cd /usr/lpp/diagnostics/bin
./update_flash
-f /tmp/fwupdate/ag030603.img
[Don't overlook the periods (.) in the above command.]
You will be asked for confirmation to proceed with the firmware update and the required reboot. If you confirm, the system will apply the new firmware, reboot and return to the AIX prompt. This may take one to ten minutes, depending on the configuration of the target system.
When you have applied the update for both the System firmware and the Service Processor firmware, the update is complete. You will want to verify this update as described in paragraph 6.3.
Enter the commands:
mkdir /tmp/fwupdate
Note: If the directory [path]\fwupdate
already exists,
make sure it is empty before proceeding.
cd /tmp/fwupdate
restore
You will be prompted to mount volume 1 on /dev/rfd0
In the drive of the target system, put the AIX backup diskette labeled,
"AIX Backup: System (L08295) and SvP (ag030603) FW for IBM 7026-H50"
The files are now located in the /tmp/fwupdate subdirectory.
Apply the System firmware update first.
Enter the commands:
cd /usr/lpp/diagnostics/bin
./update_flash
-f /tmp/fwupdate/wil08295.img
[Don't overlook the periods (.) in the above command.]
You will be asked for confirmation to proceed with the firmware update and the required reboot. If you confirm, the system will apply the new firmware, reboot and return to the AIX prompt. This may take up to ten minutes, depending on the configuration of the target system.
At the new AIX prompt, apply the Service Processor firmware update.
Enter the commands:
cd /usr/lpp/diagnostics/bin
./update_flash
-f /tmp/fwupdate/ag030603.img
[Don't overlook the periods (.) in the above command.]
You will be asked for confirmation to proceed with the firmware update and the required reboot. If you confirm, the system will apply the new firmware, reboot and return to the AIX prompt. This may take up to ten minutes, depending on the configuration of the target system.
When you have applied the update for both the System firmware and the Service Processor firmware, the firmware update is complete. You will want to verify this update as shown in paragraph 6.3.
Don't forget to retrieve and file any firmware update diskette that may still be in the system's diskette drive. A good time to do this is after the reboot has completed.
Instructions for these two methods are slightly different, so be sure to choose the correct instructions for your environment.
