For example in VPD displayed above, 50 Hex= ASCII character "P";  36 Hex= ASCII character "6"; 55 Hex=ASCII character "U"; 33 Hex=ASCII character "3",  microcode level is "P6U3". Also note that the microcode level "P6U3 " 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 VAHDD7K6.bin c) Unpack the file by executing the instructions below.   Enter the commands:   cd /tmp/fwupdate   chmod +x VAHDD7K6.bin   ./VAHDD7K6 [Don't overlook the periods (.) in the above command.] The directory He10 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/VAHDD7K6/*  /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/ HUS* | 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 VAHDD7K6-P6U3-AIX.rpm c) Unpack the file by executing the instructions below:     Enter the commands:         rpm -ihv --ignoreos  --force VAHDD7K6-P6U3-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. Type diag at the prompt. 2. Select the "Task Selection" from diagnostics menu. 3. Select "Microcode Download" from "Task Selection" menu. 4. Select resource that microcode will be applied to(hdisk?
