A3C4

Drive FW enhancements to prevent a possible undetected data loss or data error during a proximal write.  (The “proximal write” feature improves performance of the drive by combining operations that are to locations that are close to one another.)  This issue occurs when the starting logical Block Address (“LBA”) is a reassigned LBA.

Original Release

 

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

2.  AIX and VIOS (PowerVM Virtual I/O Server)

Note: For VIOS systems, microcode of shared physical I/O resources can only be updated from VIOS partition.

To update disk drive microcode, from VIOS partition, enter the following command:     

oem_setup_env   

Then follow the instruction in section 2.3 to transfer/extract the microcode file, and section 2.4.1 to update the disk drive code.

2.1 Installation Time

Approximately 20 minutes if using Diagnostics CD; Approximately 5 minutes/drive using AIX concurrent diagnostics.
 

2.2 Determine Drive Model, FRU&PN and Current Microcode Level
To see the drive type and current microcode level, Execute the following command:
lscfg -vl hdisk* |pg      ; For drives NOT configured for RAID

lscfgvl pdisk* |pg     ; For drives configured for RAID

 

    Example:

 

     DEVICE            LOCATION                                                         DESCRIPTION

      hdisk1           U4545.001.07CM0CP-P2-D2  SAS Disk Drive (450000 MB)

 

        Manufacturer................IBM-ESXS

        Machine Type and Model......VPCA450900EST1 N

        FRU Number..................44W2240

        ROS Level and ID............41334334

        Serial Number...............JVV1DJAE

        EC Level....................L81062

        Part Number.................44W2243

2.3 Transferring and Unpacking the Microcode Update Package

2.3.1 Internet AIX self extracting file (.bin)

a) Make a directory on AIX system to receive the AIX format file.
    Enter:      mkdir /tmp/fwupdate
b) Transfer the AIX format file to /tmp/fwupdate directory (using "Save as ...").
    You'll see the filename is 15K600-XP-A3C4.bin
c) Unpack the file by executing the instructions below.
  Enter the commands:
  cd /tmp/fwupdate
  chmod +x 15K600-XP-A3C4.bin
  ./15K600-XP-A3C4.bin
[Don't overlook the periods (.) in above command.]

The directory A3C4 with microcode files listed in section 1.1 will be added to /tmp/fwupdate.
 

d-Enter the following command to copy the microcode files to "/etc/microcode" directory:
   cp /tmp/fwupdate/A3C4/VPC*  /etc/microcode

2.3.2 Internet RPM package

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

b) Transfer the RPM format file to the /tmp/microcode directory.
    You'll see the filename is 15K600-XP-A3C4-AIX.rpm

c) Unpack the file by executing the instructions below:
    Enter the commands:
        rpm -ihv --ignoreos  --force 15K600-XP-A3C4-AIX.rpm

The file size and checksum will be verified.

The microcode files will be added to /etc/microcode/
 

2.3.3 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. Microcode files will be copied to /usr/lib/microcode

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.
