If this level is already installed then the "ROS Level and ID...." shows: "*44413033*" *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, 44Hex= ASCII character "*D*"; 41 Hex= ASCII character "*A*"; 30 Hex=ASCII character "*0*"; 33 Hex=ASCII character "*3*", microcode level is "*DA03*". Also note that the microcode level "*DA03*" 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 SAS15K7.bin c) Unpack the file by executing the instructions below. Enter the commands: cd /tmp/fwupdate chmod +x SAS15K7.bin ./SAS15K7.bin [Don't overlook the periods (.) in the above command.] The directory SAS15K7 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/ SAS15K7/ST3* /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/ ST3* | 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 *SAS15K7-DA03-AIX.rpm* c) Unpack the file by executing the instructions below: Enter the commands: *rpm -ihv --ignoreos --force **SAS15K7?DA03-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. *========================================================* 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 is used(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?
