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 lscfg ?vl pdisk* |pg     ; For drives configured for RAID      Vital Product Data (VPD)   Hdisk0          U5886.001.P81T030-P1-D10  SAS Disk Drive (600000 MB)      Manufacturer............................IBM             Machine Type and Model......ST600MP0005         FRU Number..............................00E8653         ROS Level and ID....................37363143         Serial Number.............................6XN01AMY         EC Level.....................................N23780            Part Number.............................00E8651         Device Specific.(Z0)...............000006329F001002         Device Specific.(Z1)...............0425761C             Device Specific.(Z2)...............0021         Device Specific.(Z3)...............11044         Device Specific.(Z4)........         Device Specific.(Z5)...................22         Device Specific.(Z6).................N23780          If the data returned in the ?Part Number?, ?FRU Number?, and ?Machine Type and Model?  fields match the one listed in section 1.1 AND the "ROS Level and ID...." field of that data is below "37363141", this microcode applies. Note: Drive microcode level in ?ROS Level and ID ?? field is displayed in Hex value of ASCII characters in VPD data. Each alpha-numeric ASCII character converts to a 2-digit hex number. For example in VPD displayed above, 37 Hex= ASCII character "7";  36 Hex= ASCII character "6"; 31 Hex=ASCII character "1"; 43 Hex=ASCII character "C",  microcode level is "761C". Also note that the microcode level "761C " is displayed in ?Z1? field. =============================================================== 2.3 Transferring and Unpacking the Microcode Update Package 2.3.1 Internet AIX self extracting file (.bin) a) Make a directory on an 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 BP5XX15KHDD.bin c) Unpack the file by executing the instructions below.   Enter the commands:   cd /tmp/fwupdate   chmod +x BP5XX15KHDD.bin   ./BP5XX15KHDD.bin [Don't overlook the periods (.) in the above command.] The directory BP5XX15KHDD 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/ BP5XX15KHDD/ST9*  /etc/microcode e- If transferring files to a different system using floppy diskettes, use the following procedure to copy files to diskette    Note: Don't overlook the complete path of microcode files, AIX Diag microcode download   will not work if files are not copied with complete path onto the diskette.  Enter the following command to copy microcode file(s) onto a floppy diskette ls /etc/microcode/ microcodefilename  | backup -ivf /dev/rfd0 where microcodefilename is  microcode file that is needed, for example: ls /etc/microcode/ ST* | backup -ivf /dev/rfd0 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 BP5XX15KHDD?761C-AIX.rpm c) Unpack the file by executing the instructions below:     Enter the commands:         rpm -ihv --ignoreos  --force BP5XX15KHDD?761C-AIX.rpm   ;(please note, there are two dashes) 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. ======================================================== 2.4 Microcode Download Procedure Warning: Do not power off the system or the drive during microcode download as this may permanently damage the disk drive NOTE: Please save current and older versions of the microcode update files in case you need to restore your system. Caution: The microcode download process is nondestructive to the hard disks; however, as a precaution, ensure that a backup operation has been performed on the affected systems PRIOR to the microcode installation. Can microcode be installed Concurrently?  YES Is system reboot needed to activate the microcode: Yes if stand alone diagnostics CD is used, NO if concurrent diagnostics is used. Installation Time: Approximately 20 minutes/drive if stand alone diagnostics isused(using Diagnostics CD); Approximately 5 minutes/drive if concurrent diagnostics is used. 2.4.1.2.1 Concurrent Download 1.
