The tape passage counter from which time to clean is calculated was not working correctly. Firmware will now update length used every 25 tape motion hours, and prior to eject for any left over tape passage distance. The cleaning required threshold was also changed from 500 tape motion hours to 100 tape motion hours. Certance internal test data shows 100 hours to be useful in some specific cases. Impact: Drive cleaning LED will not turn on at the expected 500 tape motion hours. Exposure: Any drive at version 1527 or lower firmware may experience the problem. Root cause: A firmware bug in the drive cleaning algoritum. Technical fix: Uplevel the drive to firmware version 1608. B.0 Precautionary Statements ----------------------------- **WARNING:****WARNING:****WARNING:****WARNING:****WARNING:****WARNING:** B.1 The system MUST BE IDLE during the firmware download process! No other programs should be running while this utility is being used. Failure to do so may cause the devices being upgraded to fail or the system to crash. Any other computers sharing the same I/O bus as the host system must be either disconnected or offline. B.2 If any upgrade failures occur, do not continue upgrading devices. For example, loss of power during download will result in damaged peripherals and require replacement. If any failures occur, please collect the following log file: "/var/adm/messages", and an explorer dump. Please forward these files to your service provider for analysis. B.3 This package will only function on Seagate Certance LTO1 Ultrium SCSI Tape Drives (ULTRIUM06242-xx, st string Seagate Ultrium LTO) which were shipped/used in Sun StorEdge L25/L100 tape libraries. B.4 Please READ instructions below completely BEFORE starting download procedure. Follow the procedures carefully. You may program multiple drives at the same time, however, you may not exit the utility until all drives have completed the download process. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ C.O Patch Installation and Utility Usage Intructions ----------------------------------------------------- C.1 General guidelines for upgrading: EJECT MEDIA FROM DEVICE TO BE UPGRADED. Download utility will eject media from the device if it is found to be loaded. Do NOT attempt to force media back into the drive. Media present in a device having firmware downloaded to the device may result in data loss from media or damage to device. STOP ALL APPLICATIONS. The system must be idle during the firmware upgrade process. DISCONNECT or take OFFLINE any other computers sharing the same I/O bus as the host. UPGRADE the tape device. Follow the given instructions in the procedure section below. In case of any disruption or unforeseen events happening on the relevant bus during the firmware download process, it may be that the upgraded device becomes non-functional. In this event, it will be necessary to replace the device. This would happen as a result of an incomplete or corrupted firmware file being downloaded. Loss of power during the upgrade process would also damage the device. **NOTE** If you cannot upgrade devices due to software application interference, try booting off of the Solaris release CD. **NOTE** After the firmware download is completed, it may be necessary to power cycle the device to ensure fully resetting the device. In turn, this may also require a successive reboot of the host system to ensure all functionality is restored. C.2 Procedure for Tape Firmware Download: The procedure to be used for upgrading the device's firmware is explained below. Upgrade time will be approximately 3-5 minutes for each device. You must have root/super-user privileges in order to perform this operation. a). Unpack the patch (through tar) into any directory, e.g. /var/spool/patch (Note, if the patch ends in a ".Z" suffix, you will need to first uncompress it.) Example: # uncompress # tar xvf b). In the patch directory, as root, type the "tload" command: # ./tload V16082626-078.IMG c). Select the tape device to be upgraded (see example below). **NOTE** This upgrade can result in error messages in the console window and/or the terminal "tload" window. It is normal for a SCSI bus reset message to appear in the console window for each device that is upgraded. d). Ensure that the device to be upgraded is the correct one and answer the question: Do you want to download firmware to this tape device [N]? with a 'y' for yes or anything else for no. Default answer is no. e). After each device has been upgraded, the displayed tape device list will be refreshed. Device(s) upgraded should reflect having the new code level, "1608", in the "Rev" field (see example below). f). If there is an additional device to be upgraded (same device type and desire to upgrade to the latest firmware), select that device as previously done in C.2.c). & C.2.d). above. Continue in this fashion until all desired devices have been upgraded. g). Quit the "tload" program by typing '0' (see example below). ************************************************************************** C.3 EXAMPLE # ######################################### # # Launch Tape Firmware Download Utility: # ######################################### # # ./tload V16082626-078.IMG ATTACHED DEVICES: Device Supplier Product Rev Serial Number Device State -------------- -------- ---------------- ---- ------------- ------------- 1:0ln SEAGATE ULTRIUM06242-XXX 1527 HM0098K Available 2:1ln SEAGATE ULTRIUM06242-XXX 1527 HM0098M Available Select Device(s) (ex: 1,3-4) or 0 to quit) [1]: 1 0ln SEAGATE ULTRIUM06242-XXX 1527 HM0098K Selected Do you want to download firmware to this device [N]? y ATTACHED DEVICES: Device Supplier Product Rev Serial Number Device State -------------- -------- ---------------- ---- ------------- ------------- 1:0ln SEAGATE ULTRIUM06242-XXX 1527 HM0098K Downloading 2:1ln SEAGATE ULTRIUM06242-XXX 1527 HM0098M Available Ejecting Tape out of the Tape Drive Downloading /dev/rmt/0ln... please wait.

SYNOPSIS tload [ filename ] [ -v ] filename firmware/microcode filename DESCRIPTION tload is an firmware download utility for Sun supported tape devices. If the firmware_file is specified, then it will display the list of tape devices present on the host system and asks the user to select the tape device which is to be upgraded. If the firmware_file is not specified, then it will display the list of tape devices present on the host system along with their FIRMWARE revision levels. tload will exit upon completion; please do not attempt to halt or stop prior to utility's menu exit option being presented. The command can be run only as a super-user. DISCLAIMER This utility is ONLY supported for downloading, to Sun supported tape devices, the Sun supported firmware binary (firmware_file) which has officially been released via the official Sun Patch Process. This utility is only supported with the release of firmware (binary) bundled with said patch. Do not attempt to use any other version of 'tload' that may have been acquired previously else device damage may occur. Use only the tload version provided with this patch. Use of tload to load non-Sun supported tape devices is at the user's own risk, and is not supported. Use of tload to load Sun supported tape devices with firmware NOT bundled with the utility in an officially released Sun Patch is at the user's own risk, and is not supported. PROBLEMS Any problems regarding this utility by the user following proper procedures should be reported to the user's service provider along with the following items: 1) /var/adm/messages file 2) explorer dump 3) tload V16082626-078.IMG -v Patch Installation Instructions: ------------------------------------- Please refer Problem Description section.
