=====================================================================================

1.0 Microcode Change History:
 

0040	-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).
003e	First pSeries released microcode level -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.
003b	Previously available code level
003a	Previously available code level

Note:  In order for Ultra320 to function properly a minimum level of microcode is required for the DASD.  These are listed below

2.0.0 General information

2.0.1 Installation Time:
     Approximately 30 minutes
 
2.0.2 Machine's Affected:
      iSeries machines w/ pSeries partitions
      9111-520
      9117-570
      9124-550/720
      9406-520/550/750   

2.0.3 AIX Requirements:
      For support:  AIX 5.1 ML_04 or AIX 5.2 ML_01
      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 sisioa

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 sisioaX

Where X is the number/s of the previous command. The Command will produce output similar to

    DEVICE       LOCATION         DESCRIPTION

  sisioa0          P1  PCI-X Quad Channel U320 SCSI RAID Adapter

      PCI-X Quad Channel Ultra320 SCSI RAID Adapter:
        Part Number.................53P3821
        FRU Number..................53P3821
        Serial Number...............YL3084065004
        Manufacture ID..............0008
        EC Level....................0
        ROM Level.(alterable).......030E003a
        Product Specific.(Z0).......2780
        Device Specific.(YL)........P1

If the ROM Level is less than XXXX0040 then you should update the microcode.

4.0.1 Downloading and Unpacking the Firmware Update Package from CORE

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 raidquad.0040.rpm

c) Unpack the file by executing the instructions below:
    Enter the commands:
        rpm -ihv --ignoreos raidquad.0040.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 raidquad.0040.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 Quad 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:  1070064
Checksum:  51221

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 Quad 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 5349530E.030E0040
    G.  Type: quit
    H.  Verify the filesize and checksum of the file by typing:
            1) Filesize:  "ls -l 5349530E.030E0040".  The filesize should be 1070064.
            2) Checksum:  "sum 5349530E.030E0040".  The checksum should be 51221.
    I.   Follow the above procedure to download the microcode to all PCI-X Quad Channel Ultra320 SCSI RAID Adapter' in the partition.
 

13. Verify the code level is 0040 by typing "lscfg -vl sisioa#" for each scsi device updated. <Where # is the number sisioa device>
