5.0 Microcode Download Procedure-PCI-X Dual Channel Ultra320 SCSI RAID Adapter

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

1.0 Microcode Change History:
 

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.
002f	GA level

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

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 XXXX0059 then you should update the microcode.

b) Transfer the AIX format file to the /tmp/microcode directory (using "Save as ...").
You'll see the filename is sisraid0059.bin

c) Unpack the file by executing the instructions below. You will be asked for the password from the license agreement.
Enter the commands:
cd /tmp/microcode
chmod +x sisraid0059.bin
./sisraid0059.bin
[Don't overlook the periods (.) in the above command.]

The directory sisraid0059 with these files will be added to /tmp/microcode.
1) 5052414D.03090059 (Microcode Image)

Enter the following command to copy the microcode files to " /etc/microcode " directory :
cp /tmp/microcode/sisraid0059/5052414D.03090059  /etc/microcode

Enter the following commands to copy these file onto a diskette:
ls /etc/microcode/5052414D.03090059 | backup -i -v -f/dev/rfd0

This will produce AIX backup diskettes. Label the diskettes:
"PCI-X Dual Channel Ultra320 SCSI RAID Adapter"
 

4.0.1 Downloading and Unpacking the Firmware Update Package from CORE

With the machine powered ON and AIX operational but no activity,
perform the following steps to install the FLASH code into the
SCSI RAID Adapter.

1.  Insert diskette with the file downloaded from CORE into the floppy diskette drive of the Media Bay.

NOTE:  If the system is running LPAR, you must determine what partition has the media bay assigned.

How to determine what partition has the diskette drive assigned when running LPAR:
    A.  Log onto the Hardware Management Console (HMC).
    B.  On the opening screen, in the Navigation Area, select Partition Management.
    C.  In the Partition Management window, right-click on the top device listed in the window.  Select Properties.
    D.  Select the IOSLOT tab.
    E.  In the IOSLOT field, find the SCSI initiator named PCI-X Dual Channel Ultra320 SCSI RAID Adapter .
    F.  Click on the + sign next to the I/O Group associated with the PCI-X Dual Channel Ultra320 SCSI RAID Adapter.  This will display the partition associated with the diskette drive.

2.  Log into the target system (or LPAR that has the media bay assigned) as root.

3.  Type: restore
 

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.0059.rpm

c) Unpack the file by executing the instructions below:
    Enter the commands:
        rpm -ihv --ignoreos sisraid.0059.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.0059.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:  1024068
Checksum:  52825

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.03090059
    G.  Type: quit
    H.  Verify the filesize and checksum of the file by typing:
            1) Filesize:  "ls -l 5052414D.03090059".  The filesize should be 1024068.
            2) Checksum:  "sum 5052414D.03090059".  The checksum should be 52825.
    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 0059 by typing "lscfg -vl sisraid#" for each scsi device updated. <Where # is the number sisraid device>
