Prior to microcode update, a
shutdown is performed to the I2C bus to acquiesce activity. This
prevents the I2C bus from getting hung and the Virtual SES devices from
coming up "defined". |
005f |
-Virtual SES code fix (SF2,
L4). 1) (SF2, L4) I2C bus may hang when adapter reset occurs while the adapter is reading the EEPROM on the I2C bus. Reduce window of occurrence. 2) (L4). I2C bus timeout when adapter is reset and running diagnostics. -SCSI RAID fix. 1) Fix for Adapter Unit Check when Fast/Write Cache not operational (e.g. bad battery, bad NVRAM stick). 2) Added Notification of battery/charger not working. 3) Enhanced error log for Read Cache error . 4) Change in cache implementation from Stack (LIFO) to Queue (FIFO). |
005d |
-Virtual SES fixes: a) LED
fix for L4 system and b) PCI-X Quad Channel Ultra320 SCSI RAID Adapter
fix for all systems -Error log changes: a) Differentiated a error condition. Adapter now logs a specific error instead of generic for a given situation. b) Return the correct error information to the pSeries Adapter Device Driver (ADD) so a SCSI adapter detected CRC error is logged instead of a program error microcode problem. Problem was seen on L4, SF2 and SF4. -Added Linux support features and fixed Linux drive replacement problem -Force SE mode to 20MBps when an SE device is connected to the 7029-6C3/6E3 new feature backplane. This backplane expands the Integrated SCSI Controller adding an external port. |
0059 |
External SE device fix;
external SE devices are limited to 20MBps. Added support for unique vendor command on 3580/3583 LTO tape device. Modification to run Ultra320 speeds using Linux kernel 2.6. Various performance enhancements. |
0051 |
Resolves SCSI_ERR10 (SCSI Bus Reset) condition upon Diagnostic's System Verification or Microcode Download in 7028-6C1 w/ safte device. |
004d |
Enhanced SCSI signal path
validation. Removed extended Target Mode delays. Removed erroneous AIX errors logged during drive microcode download. Added unique RAID array identifiers for Linux support. Removed erroneous SCSI bus reset error logged when a device reports an error condition. Corrected extended SCSI bus reset that may occur when running HACMP. |
0042 |
Installing two 4-pack backplanes
in a p615 may cause the second backplane (sesX) to boot in the defined
state or not be seen. Microcode 0042 corrects this problem. |

For U320 support: AIX
5.1 ML_05 or AIX 5.2 ML_02 along w/ the aforementioned minimum DASD
microcode requirements.
3.0 Determine the Current Microcode Level:
Before you install the microcode, it is important to determine the microcode level of the Adapter installed in the target system. Use
the following instructions to read the ROM level stored in the Adapter's VPD.
1) List the SCSI RAID Adapters installed in the system by typing:
lsdev -C | grep sisraid
Note: All of the SCSI RAID initiators addresses that are installed will bedisplayed. The names will be sisioaX, where X is 0, 1, etc.
2) To check the current microcode level for the adapter or controller enter the following command
lscfg -vl sisraidX
Where X is the number/s of the previous command. The Command will produce output similar to
DEVICE LOCATION DESCRIPTION
sisraid0 U0.1-P1-I5 PCI-X Ultra320 SCSI RAID Adapter
PCI-X Dual Channel Ultra320 SCSI RAID Adapter:
Part Number.................97P2702
FRU Number..................97P2702
Serial Number...............YL1093175020
Manufacture ID..............0009
EC Level....................0
ROM Level.(alterable).......0309002f
Product Specific.(Z0).......5703
Product Specific.(Z1).......1
Device Specific.(YL)........U0.1-P1-I5
If the ROM Level is less than XXXX0061 then you should update the microcode.
4.0.1 Downloading and Unpacking the Firmware Update Package from CORE
NOTE: The CORE image will now be the RPM Format File.4.0.2 Downloading the RPM Format File
to the Target Server
Use this
method to download to an AIX system:
Note: The instructions that follow are specific AIX commands. AIX commands are CASE (lower and upper) SENSITIVE, and must be entered exactly as shown, including filenames.
a) Make a
directory on an AIX system to receive the RPM format file.
Enter: mkdir /tmp/microcode/RPM
b) Transfer the
RPM format file to the /tmp/microcode directory (using "Save as ...").
You'll see the filename is sisraid.0061.rpm
c) Unpack the file by executing the instructions below:
Enter the commands:
rpm -ihv --ignoreos
sisraid.0061.rpm
The microcode files will be added to /etc/microcode/
4.0.3 Downloading File from the Microcode CD-ROM
Copy microcode updates from the CD-ROM to standard locations on your local disk:
1. RPM packaged microcode files will be copied to
"/tmp/microcode/RPM"
2. Unpack the file by executing the instructions below:
Enter the commands:
rpm -ihv --ignoreos sisraid.0061.rpm
3. Microcode files will be copied to "/etc/microcode".
- "/etc/microcode" is a symbolic link to "/usr/lib/microcode".
- If permission does not allow the copy to the above stated
directory
or file then the user will be prompted for a new location.
5.0 Microcode Download Procedure-PCI-X Dual Channel Ultra320 SCSI RAID Adapter
NOTE: Microcode download must be performed
seperately for each Adapter under distinct Logical Partitions
(LPAR's).
Please save current and older versions of the microcode update files in
case you need to restore your system.
NOTE: Microcode Download CAN be performed concurrently.
Installation Time: Approximately
30 min System Time.
Please verify the file size and checksum of the raw microcode files
in /etc/microcode/. See step 10H.
Filesize: 1025924
Checksum: 59594
Procedure:
1. Stop all applications.
2. Enter diag
3. Select the "Task Selection" from diagnostics menu.
4. Select "Microcode Download" from "Task Selection"
menu.
5. Select all of the PCI-X Dual Channel Ultra320 SCSI
RAID Adapters
that needs to be updated from the list of devices by pressing "Enter".
The devices will be displayed as sissioa#, where # is the number of the
device. Press "F7".
6. A diaglogue box will be displayed on screen. Press "Enter" to
continue.
7. Select "/etc/microcode".
8. A dialogue box will may be displayed on screen. It will state
that
the current microcode level on the adapter is not in the /etc/microcode
directory. This is acceptable as you will be flashing new
microcode
onto the adapter. Also, incorrect code will automatically be
rejected. Press "Enter" to continue.
9. An "M" will be displayed next to the latest level of microcode in
the /etc/microcode directory. Select that level and press "Enter".
10. The following message
will
appear on the screen when download is completed: "Microcode download
complete successfully. The current microcode level for the device
sisscsia# is ..... Please run diagnostics on the adapter to
ensure
that it is functioning properly." DO NOT run
diagnostics on the device at this time.
11. Exit diagnostics.
12. For systems that have LPAR installed, the microcode file must be placed on all partitions that have a SCSI RAID device in order to update the code. Follow this procedure for each partition:
A. Log into the
target partition.
B. Type: cd
/etc/microcode
C. FTP to the partition
that has the media bay assigned. (ie. ftp partition1.ibm.com)
D. Type: cd
/etc/microcode
E. Type: bin
F. Type: get 5052414D.03090061
G. Type: quit
H. Verify the filesize
and checksum of the file by typing:
1) Filesize:
"ls -l 5052414D.03090061". The filesize should
be 1025924.
2) Checksum: "sum 5052414D.03090061". The checksum should be 59594.
I. Follow the above procedure to
download the microcode to all PCI-X Dual Channel Ultra320 SCSI RAID
Adapter'
in the partition.
13. Verify the code level is 0061 by typing "lscfg -vl sisraid#" for each scsi device updated. <Where # is the number sisraid device>
