Overview

Following is the instructions for updating the firmware (microcode) of the
IBM RISC System/6000 SCSI-2 Enhanced Differential Fast/Wide Adapter (4-C)
FC 2412 [Corvette Turbo]. The installation of this firmware level is
required. The file systems created on disks connecting to the adapter will
be temporarily unavailable while the firmware is being updated.

Before Updating the Adapter Firmware

Before updating the adapter firmware, you must follow the instructions
below to verify whether or not you have the appropriate level of adapter
hardware and firmware in your system.

1)  Issue the following command to list the PCI SCSI adapters installed in
the system:

lsdev -C | grep "ascsi"

All installed SCSI adapters will be listed as available. The adapter device
names will be in scsci# format, where # is the numeric logical
identification of each adapter device.

2) To check the current microcode level for the adapter enter the following
command

lscfg -vl ascsi#

Note the FRU Number and the Loadable Microcode Level fields.  If the FRU
Number is 93H7896 and the Loadable Microcode Level is less than C9, the
system contains the appropriate adapter hardware level and a down-level
adapter firmware.  You should update the adapter firmware.

Updating the Adapter Firmware

1) Obtain EMT file "corvC9.EXE" or AIX binary file "8EFC3088.C9M"  (if you
already have the AIX file skip to step 3)

2) Unpack the EMT file in order to obtain the AIX binary file on diskette

3) With the machine powered on and AIX operating system successfully
loaded, follow the instructions below to install the FLASH code onto your
SCSI adapters.

4) Log in as root

5) Copy the AIX binary file "8EFC3088.C9M" from diskette into the
/etc/microcode directory

6) You are now ready to FLASH the EEPROM in the adapter using the single
command:

diag -c -d ascsi# -T"download"

Where # is the number found from the "lsdev -C | grep ascsi" command.
Repeat the above command for all the cards that need the update.

If you require further instruction refer to the RS/6000 microcode download
procedure.
