Users are responsible to install the latest microcode level. The microcode and instructions are available at the IBM external web site: http://www.ibm.com/support/fixcentral ---------------------------------------------------------------------------------- Operating System levels supported: All levels of AIX that this product was announced on. ---------------------------------------------------------------------------------- Installation Time: The typical time to install this microcode is .2 hrs. The microcode becomes active when installed and does not require a system reboot to become active. ---------------------------------------------------------------------------------- Can microcode be installed Concurrently? Yes, but the tape drive must be available with no tape in the drive, and no other processing running to the tape drive. ---------------------------------------------------------------------------------- Is system reboot needed to activate the microcode A reboot is not needed as the microcode is active in the drive when the drive completes microcode download. ---------------------------------------------------------------------------------- Microcode Download information: In order to complete the microcode download to the tape drive you will need to use the AIX diagnostics. The AIX diagnostic package will need the microcode and dsdata files in this package. Note: Atape does not require the dsdata file. This tape drive package will get you to step where you will need to use the AIX Diagnostics. ---------------------------------------------------------------------------------- Additional Cautions Remove any tape cartridge from the drive prior to attempting the microcode download. Do not power off the tape drive during microcode download as this may damage the tape drive microcode requiring the tape drive to be replaced. ---------------------------------------------------------------------------------- Machines Affected: All Power Systems this product was announce on. In general if the tape drive configures and is available with the VPD showing the Machine Type and microcode level as described in this README the machine is one affected. ---------------------------------------------------------------------------------- SAS Feature Code: EU11, 8347, 8341 Display Microcode Level Note: In some cases you may already have the most current level of microcode already installed. The following instructions show you how to check the tape drive microcode level. To display the level of microcode in the 2.5TB Half High LTO-6 tape drive do the following AIX command: lscfg -vl rmt0 <--- change the drive number to reflect the actual rmt address of the 2.5TB Half High LTO-6 tape drive. The output of the lscfg command will look like the following with the: * "Device Specific.(Z1)" showing the "Microcode Level": As of October 2011 there are 2 different P/Ns for the LTO6 drive. The drives are functionally equivalent and are fully interchangeable. rmt0 U789C.001.DQDA282-P1-C1-T1-L50000-L0 SAS 1/2-inch Cartridge Tape Drive (2500000 MB) Manufacturer................IBM Machine Type and Model......HH LTO Gen 6 Device Specific.(Z1)........KAJ9 Serial Number...............68000476 Load ID.....................A1700D84 Part Number.................35P0994 FRU Number..................35P1049 EC Level....................M12273A Device Specific.(Z0)........0180060283011002 Device Specific.(Z3)........N1 Microcode History The microcode update will bring the IBM 2.5TB Half High LTO6 SAS tape drive up to the current level of microcode which is: KAJ9 Table 1.

Each of these will put the microcode on the user's system but the user may have to move the files to appropriate directory for system use. From the IBM WEB site via the user downloading the files. When the user downloads the microcode files from the IBM web site the packaged microcode files will be put into the /tmp directory. * If the user downloads the 13 HHLTO6.bin file the user will put the downloaded file into the /tmp directory and then use the instructions in the section of this README titled "AIX bin file". * If the user downloads the TapeHHLTO6-KAJ9-01.rpm file the user will put the downloaded file into the /tmp directory and then use the instructions in the section of this README titled "RPM file". From a CD-ROM. * If the CD-ROM process is used to put the HHLTO6.bin file on the user system the microcode files will expanded into the /tmp/LTO6_web directory. The next step is to follow the instructions in this README titled "AIX bin file" and copy the files to the appropriate directory. The building and putting of the files into the /tmp/LTO6_web directory was done by the user when they used the CD-ROM build instructions. * If the CD-ROM process is used to put the TapeHHLTO6-KAJ9-01.rpm file on the user system the microcode files will be in the tmp/microcode/RPM directory. To put the microcode in the appropriate directory for the system the user executes the following AIX commands: cd /tmp/microcode/RPM rpm -ihv --ignoreos TapeHHLTO6-KAJ9-01.rpm (add --force if previous rpm package installed and get conflict error) This puts the following files in the /etc/microcode directory for system use: * HH_LTO_Gen_6.A1700D84.dsdata * HH_LTO_Gen_6.A1700D84.KAJ9 * HH_LTO_Gen_6.FC.KAJ9 The next step is to follow the instructions in this README titled "Verifying the Microcode". Note: AIX commands and file names are case sensitive. If the users AIX permission does not allow the copy to the above stated directory or file then the user will be prompted for a new location. ---------------------------------------------------------------------------------- Packaged Microcode Files AIX bin file * Download the HHLTO6.bin file to the eServer pSeries to the /tmp directory. * Do the following AIX commands to make the file executable: cd /tmp chmod +x HHLTO6.bin * To expand the HHLTO6.bin file use the following command: ./HHLTO6.bin Note: The ./ before the command insures AIX paths thru the current directory to find the command. * This will put the following files in the /tmp/LTO6_web directory: * HH_LTO_Gen_6.A1700D84.dsdata * HH_LTO_Gen_6.A1700D84.KAJ9 * HH_LTO_Gen_6.FC.KAJ9 RPM file * Download the TapeHHLTO6-KAJ9-01.rpm file to the eServer pSeries to the /tmp directory. * To expand the TapeHHLTO6-KAJ9-01.rpm file use the following commands: cd /tmp rpm -ihv --ignoreos TapeHHLTO6-KAJ9-01.rpm (add --force if previous rpm package installed and get conflict error) * This will put the following files in the /etc/microcode directory: * HH_LTO_Gen_6.A1700D84.dsdata * HH_LTO_Gen_6.A1700D84.J451 * HH_LTO_Gen_6.FC.KAJ9 ---------------------------------------------------------------------------------- Verifying the Microcode To insure the file was downloaded without error do the following: * Change to the directory where you just put the microcode. cd /tmp/LTO6_web or cd /etc/microcode * Use the AIX command sum to verify the checksum of the microcode file: sum HH_LTO_Gen_6.* * Compare the sum you got with the sum of the microcode files here, if they do not match recheck your steps in creating the file on the system: 29702 6142 LTO6_web/HH_LTO_Gen_6.A1700D84.KAJ9 17620 2 LTO6_web/HH_LTO_Gen_6.A1700D84.dsdata 04868 6196 LTO6_web/HH_LTO_Gen_6.FC.KAJ9 ---------------------------------------------------------------------------------- Updating the microcode in the drive You need to determine how you are going to download the microcode: * AIX diagnostics. AIX diagnostics naming and supported directory for the microcode and dsdata file. * AIX diagnostics requires the microcode file and the dsdata file to be in the /etc/microcode directory. * For Atape it is not necessary to copy the files to another directory. Atape can use any directory. Use the /tmp/LTO6_web directory. Copy Dsdata and Microcode to appropriate directory Copy the Dsdata and Microcode files to appropriate directory for use by AIX diagnostics. Note: The copy command copies the file to the new directory with the same name when you use the period(.) after new directory name. For AIX Diagnostics If you downloaded the RPM file and executed it the microcode is in the correct directory with the correct name for AIX diagnostic use. If you downloaded the .bin file and executed it then you need to do the following AIX commands: cd /tmp/LTO6_web cp HH_LTO_Gen_6.A1700D84.dsdata /etc/microcode/. cp HH_LTO_Gen_6.A1700D84.KAJ9 /etc/microcode/. To use AIX Diagnostics Microcode download There are 2 ways to do the microcode download using the AIX diagnostics. * Using the AIX Diagnostics menu * Using the AIX Diagnostics via command line input. Using the AIX Diagnostics menu To use the AIX Diagnostics menu for microcode download do the following: Note: There are differences between AIX levels of AIX Diagnostics. In some cases the step after Task selection is Microcode Tools, or Download Microcode. The following steps are general instructions to download microcode. diag (enter) Task Selection (enter) Microcode Tasks (enter)   Download Microcode (enter) Select the drive you wish to download microcode to and follow the system instructions. Note: When the system asks where the microcode file is to be found select /etc/microcode Using the AIX Diagnostics via command line input. The command line to download microcode will use the highest level of microcode in the /etc/microcode directory for the device selected. To use the AIX Diagnostics command line input for microcode download do the following: Note: If the previous level of microcode is not in the /etc/microcode directory you will need to use the -f option(force) as the diagnostics expect the previous level to be present in the /etc/microcode directory. Note: If the microcode download fails install: * Insure the checksum is correct for the files that you have downloaded * If the download to the tape drive fails, use the eject button on the tape drive to reset the drive. Some microcode download failures leave the drive in way that the tape drive will not complete a download without the tape drive being reset. To reset the tape drive press the eject button and hold the eject button pressed in for 15 seconds, this will cause a drive reset.   diag -c -d rmt0 -T "download" (enter) or diag -c -d rmt0 -T "download -f" (enter) To Update the Microcode on IBM i System * Download the drive code HH_LTO_Gen_6.A1700D84.KAJ9 (SAS HHLTO6) * Update the firmware Please follow this link to determine and update the drive firmware under IBM i system: https://www.ibm.com/developerworks/community/wikis/home?lang=en#!/wiki/IBM%20Removable%20Media%20on%20IBM%20i/page/Updating%20firmware%20on%20selected%20stand%20alone%20drives Use Atape to update the Fibre Channel Drive Only. Note: Atape must be installed on the system prior to running AIX diagnostics. Enter AIX diagnostics and select "Task Selection" Select "IBM Tape Drive Service Aids" Select "Microcode load" and fill in the required fields. Note: The microcode file used by Atape for the Fibre Channel LTO6 tape drive is: /tmp/LTO6_web/HH_LTO_Gen_6.FC.KAJ9 ---------------------------------------------------------------------------------- Drive SELF-TEST Procedure ---------------------------------------------------------------------------------- Description The following procedure is designed to allow you to quickly perform a complete set of diagnostic tests on your Half High LTO-6 tape drive, without impacting server operation. This 5 < minute test can also be used to verify good performance of individual LTO6 tape cartridges. ---------------------------------------------------------------------------------- Enter Diagnostic Mode: * Verify that a tape cartridge is not loaded in drive. To unload a cartridge, press the eject button on the front of the drive. * To Start Drive SELF-TEST: Press and hold the eject button for more than 6 seconds, and less than 20 seconds(at 20 seconds the drive will do a manual reset and not run the full drive self test), release the button. The Ready LED will continue flashing, indicating that the drive is waiting for a cartridge to be inserted.The drive will wait up to 15 seconds for a cartridge to be inserted. If no cartridge is inserted the drive will exit self test. ---------------------------------------------------------------------------------- Running the Self-Test: * Start the self-test by inserting IBM Test Tape P/N 45E1129 into the drive. If an IBM Test Tape is not available, you can substitute a scratch (blank) LTO6 data cartridge.Note: Important! Use a blank cartridge that does not contain customer data. During this self-test, the cartridge will be rewritten with a test pattern and any customer data will be destroyed. Overall test duration is about 5 < minutes. Note: * A cartridge must be loaded within 15 seconds -- otherwise, the drive will automatically revert back to normal operation. If necessary, return to step 1 to reenter diagnostic mode. * Use a cartridge that is not write-protected. If a write-protected cartridge is inserted while the drive is in diagnostic mode, the cartridge will be ejected -- see step below. * Self-testing can only be performed using a write-compatible cartridge type, and with a cartridge that is not damaged -- see step below. * If a cleaning cartridge is inserted while the drive is in diagnostic mode, cleaning will occur and the drive will then return to normal operating mode. To reenter diagnostic mode, return to the "Enter Diagnostic Mode" step. * At any time, self-testing can be stopped by pressing the eject button. After a current test operation is completed, the cartridge will be ejected and drive will return to normal operation. * While self-testing is in progress, the Ready LED will continue to flash. The following 3 test steps are performed: * The initialization sequence has an approximate duration of 20 seconds. The Activity LED indicates tape movement. * The hardware test has an approximate duration of 2 minutes. During that time, a static test is performed on the drive's electrical components, and proper operation of the cartridge load/unload mechanism is verified. * The write/read test has an approximate duration of 3 minutes. The Activity LED indicates tape movement. ---------------------------------------------------------------------------------- Interpreting the Results: Test Passed: When self-testing has completed successfully and no problems were detected, the cartridge is unloaded from the drive and all LEDs and SCD are off. Proper function of both the drive and tape cartridge have been verified. Note: When the Amber Clean LED remains on, it indicates that self-testing has completed successfully -- but cleaning is required. Clean the drive by inserting an IBM Cleaning Cartridge (P/N 35L2086). The drive is no longer in diagnostic mode, and has been returned to normal operation. Drive Failure: When a drive problem is detected, the cartridge will remain loaded inside the drive and the Amber Fault LED ( ! ) will flash. Following a self-test failure, the tape cartridge will remain loaded inside drive, and the drive will remain in diagnostic mode. Press the eject button to unload tape cartridge and return drive to normal operation. Repeat self-test using another tape cartridge, If the test passes replace any defective media. If the test again failed contact IBM Service for assistance. Media Failure: When a media problem is detected, the cartridge will remain loaded inside the drive, and the Amber Clean LED will flash. Repeat self-test using another tape cartridge, and replace any defective media. Incorrect cartridge: When the drive has determined that an incorrect tape cartridge was inserted, the cartridge is unloaded and both the Activity and Clean LEDs will flash. Self-testing cannot be performed if the inserted cartridge is one of the following: * Write-protected * Damaged * Media type that is not write-compatible with the drive Press the eject button, to end self-test and return the drive to normal operating mode. Then return to step 1 and run the self-test using a suitable cartridge. Return to Normal Operation: Following a self-test failure, the tape cartridge will remain loaded inside drive, and the drive will remain in diagnostic mode. Press the eject button to unload tape cartridge and return drive to normal operation. ---------------------------------------------------------------------------------- Readme Change History Table 3.
