or above

 

*2.5 IBM i Requirements:*

*3.0 Determine the Current Microcode Level for AIX:*

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 SES installed in the system by typing:

    lsdev -C | grep ses

Note: All of the SAS RAID initiators addresses that are installed will
be displayed. The names will be sesX, where X is 0, 1, etc.

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

   lscfg -vl sesX

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

 

* DEVICE   LOCATION                                 DESCRIPTION*

   ses0             U78C9.001.RIH0001-P2-Y2  SAS Enclosure Services Device

 

      SAS Expander:

        FRU Number..................00E1978

        Serial Number...............YL10UF3CB01K

        Customer Card ID Number.....2B5A

        Product Specific.(ZM).......1

        Load ID.....................A1700DF3

        ROM Level.(alterable).......1508

        Hardware Location Code......U78C9.001.RIH0001-P2-Y2

 

If the *ROM Level* is less than *1508* then you should update the microcode.

 

 

*3.1 Determine the Current Microcode Level for Linux:*
1) Type "iprconfig"
2) Select "Display hardware status"
3) Select SES by typing a "1" in front of it and pressing Enter.
4) The Command will produce output similar to
"*Firmware Version . . . . . . . . . . . . : 01508*"

If the *Firmware Version* is less than *1508* then you should update the
microcode.

*4.0 Downloading and Unpacking the Firmware Update Package from CORE*

NOTE:  The CORE image will now be the RPM Format File.

1) After downloading the files from CORE on to your personal system find
the following files in the CORE destination directory (c:\ibmdocs\DISKIMG):
    A) "*ses.2B5A-1508-1.aix5.1.noarch.rpm *"
    B) "*ses.2B5A-1508-1.Linux.noarch.rpm *"
2) Log in to the Target Server
3) Create a directory, if not already existent (mkdir /tmp/microcode;
mkdir /tmp/microcode/RPM)
4) Transfer the file to the Target Server "/tmp/microcode/RPM directory"
using ftp or another method.  Change to that directory, "cd
/tmp/microcode/RPM".
5a) For _AIX_:  Unpack the RPM file by using the following command: 
"*rpm -ihv --ignoreos --force ses.2B5A-1508-1.aix5.1.noarch.rpm "*
5b) For _Linux_:  Unpack the RPM file by using the following command: 
"*rpm -ihv --ignoreos --force ses.2B5A-1508-1.Linux.noarch.rpm *"
6a) For _AIX_:  The microcode files will be added to /usr/lib/microcode/.
6b) For _Linux_:  The microcode files will be added to /lib/firmware/.

*4.1 Downloading the RPM Format File to the Target Server*
Use this method to download to an AIX or Linux system:

*Note:* The instructions that follow are specific AIX/Linux commands.
AIX/Linux commands are CASE (lower and upper) SENSITIVE, and */must/* be
entered exactly as shown, including filenames.

1) Make a directory on an AIX/Linux system to receive the RPM format file.

    Enter: "mkdir /tmp/microcode"
    Enter: "mkdir /tmp/microcode/RPM"
2) Transfer the RPM format file to the /tmp/microcode/RPM directory
(using "Save as ...").  Change to that directory, "cd /tmp/microcode/RPM".

You'll see the filenames for the RPM files.
    A) For _AIX:_  The filename is *ses.2B5A-1508-1.aix5.1.noarch.rpm
*    B) For _Linux:_  The filename is *ses.2B5A-1508-1.Linux.noarch.rpm
*3) Unpack the file by executing the instructions below:
    A) For _AIX_:  Type "*rpm -ihv --ignoreos --force
ses.2B5A-1508-1.aix5.1.noarch.rpm "
*    B) For _Linux_:  Type "*rpm -ihv --ignoreos --force
ses.2B5A-1508-1.Linux.noarch.rpm "*
4a) For _AIX_:  The microcode files will be added to /usr/lib/microcode/.
4b) For _Linux_:  The microcode files will be added to /lib/firmware/.
 

*4.2 Discovery Tool Microcode CD-ROM creation and download instructions*

To obtain information how to burn a CD-ROM and run the Discovery Tool
for an AIX System please go to:
http://techsupport.services.ibm.com/server/mdownload/CDROMhelp.html
1) After running the Discovery Tool successfully the
"/tmp/microcode/RPM" directory was created and your rpm files are copied
from the CD-ROM.

2) Change to that directory, "cd /tmp/microcode/RPM".

3) Unpack the file by executing the instructions below:
    Enter the commands:
        *rpm -ihv --ignoreos --force ses.2B5A-1508-1.aix5.1.noarch.rpm*
4) Microcode files will be copied to "/etc/microcode".  The file size
and checksum of the microcode image will be verified in Section 5.0

*Notes:*
 - "/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 Verifying microcode before download and notes*

*NOTE:*  Microcode download must be performed separately for each "ses"
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 update cannot be performed to both SAS expanders
(SES) at the same time.

 

/Installation Time:  /Approximately 30 min System Time.

Please verify the file size and checksum of the raw microcode files
matches the below.*
Filesize:  197228*
*Checksum:  44977*
For _AIX_:  "ls -l /usr/lib/microcode/A1700DF3.1508 " to verify Filesize. 
                "sum /usr/lib/microcode/A1700DF3.1508 " to verify Checksum.
For _Linux_:  "ls -l /lib/firmware/A1700DF3.1508 " to verify Filesize.
                 "sum /lib/firmware/A1700DF3.1508 " to verify Checksum.

For systems that have LPAR installed, the microcode file must be placed
on all partitions that have a SES device in order to update the code. 
Follow this procedure for each partition:

For _AIX_:
    A)  Log into the target partition.
    B)  Type: "cd /usr/lib/microcode"
    C)  FTP (for AIX) or SFTP (for Linux) to the partition that has the
media bay assigned. (ie.  ftp/sftp partition1.ibm.com)
    D)  Type: "cd /usr/lib/microcode"
    E)  If using FTP then Type: "bin"
    F)  Type: "get A1700DF3.1508 "
    G)  Type: "quit"

For _Linux_:
    A)  Log into the target partition.
    B)  Type: "cd /lib/firmware"
    C)  SFTP to the partition that has the media bay assigned. (ie. 
"sftp partition1.ibm.com")
    D)  Type: "cd /lib/firmware"
    E)  Type: "get A1700DF3.1508 "
    F)  Type: "quit"

6) A dialogue box will be displayed on screen.  Press "Enter" to continue.
7) Select "/usr/lib/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
/usr/lib/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
/usr/lib/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 ses# 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.
