2.3 Operating System Requirements

If you are installing a new feature, ensure that you have the software that is required to support the new feature and that you determine whether any prerequisites must be met for this feature and attaching devices.  Consult the IBM sales manual for your system model to determine the AIX, VIOS, Linux, or IBMi release level requisites to support the feature in the system.  To check for the Feature prerequisites, see IBM Prerequisite website (https://www14.software.ibm.com/support/customercare/iprt/home).

 

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 SAS RAID Adapters installed in the system by typing:

    lsdev -C | grep sissas

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

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

   lscfg -vl sissasX

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

4c) For the Linux - Ubuntu file:  The microcode files will be added to /lib/firmware/.
 

4.2 Microcode Update via CD

Below are references and the general flow on how to update microcode update via CD
1) Boot the system via a Standalone Diagnostic's CD
b) To create a bootable Diagnostic's CD go to the following URL.
Burn cdlatest.iso on to a CD-R (or CD-RW). Currently, DVD media cannot be utilized.
http://www14.software.ibm.com/webapp/set2/sas/f/diags/home.html
c) After booting to Standalone Diagnostics, the Diagnostic's CD can be removed.

2) The Diagnostic's CD should be replaced by a CD containing the unpacked microcode image(s).
The CD containing the microcode images should be prepared prior. This can be done by taking the rpm file(s) from the microcode download site and unpacking them on a usable server. The unpacked files can then be burned on to the CD media.
b) Another method is to use a Microcode Update CD
See the below website for more details
http://www14.software.ibm.com/webapp/set2/firmware/lgjsn?mode=10&page=cdrom.html#downloadcdrom

The Microcode Update CD and Discovery Tool can also be ordered through the following link

5.0 Verifying microcode before download and notes

NOTE: Microcode download must be performed separately for each Adapter bus 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 matches the below.
Filesize:  3827056
Checksum:  57519

For AIX/Linux:  "ls -l /usr/lib/microcode/53495351.19512b00" to verify Filesize. 
                "sum /usr/lib/microcode/53495351.19512b00" to verify Checksum.
For Linux:  "ls -l /lib/firmware/pci.1014034A.51.19512b00" to verify Filesize.
                 "sum /lib/firmware/pci.1014034A.51.19512b00" to verify Checksum.

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

For AIX/Linux:
    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 53495351.19512b00"
    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 pci.1014034A.51.19512b00"
    F)  Type: "quit"
