Product Scalar 1000 641A 00003 Date December 2006 Contents Page Topic 1 Purpose of this Release 1 New Enhancement 2 Compatibility Matrix 3 Resolved Issues 4 Known Issues 4 Documentation Purpose of this Release This Scalar 1000 641 firmware release adds one new enhancement that extend the capabilities of the Scalar 1000 Library This document describes the new enhancement as well as corrections made to issues encountered in previous releases of the library Visit www adic com for additional information about Scalar 1000 641 Firmware and previous releases New Enhancement The following enhancement is in this release of the Scalar 1000 e Improved label scanning during teaching Previously teach values could vary as much as 2mm between teaches which could generate SAC 7C errors To improve scanning accuracy and reduce variance errors labels are now scanned at least twice If the X or Y value exceeds 0 5mm either X Y or both are scanned again After scanning the largest X value and smallest Y value are passed to the teach function to calculate cell positions Also to help eliminate SAC 7B errors that occurred during teach mastering the reach motor extends 1mm farther while extending to the teach master bracket Finally to alert users when a scanner might need replacing during the teach a warning message appears on the operator panel when the scan beam is not level or is jittery December 2006 ADIC AD
3. ch the operator panel and Log_Sense reported the drive s firmware level incorrectly because a string variable was not initialized correctly 30986 Corrects a condition that occurred when printing the log information in the 630 logs in which the retract retries was incorrect for previous versions 33963 Media settings are now preserved during a firmware upgrade When upgrading from 630 to 640 firmware if the media mode was set to extended it was reset to default mode after the upgrade 36097 Corrects a condition in autocleaning immediate mode in which an expired AIT cleaning tape resulted in move failure The library now recognizes an expired AIT cleaning cartridge and marks it expired in the database Additional functionality has been added to force a cleaning event on AIT 3 drives when necessary 37030 Corrects a condition that caused a SAC 7A Reach Homing Error 38272 Current scan velocity and cleaning cartridge information is now included in the library log 38796 Corrects a condition that prevented toggling element addressing between old and new styles for ADSM 39285 The library log no longer fills with meaningless errors when the library has no RMU installed Only one message is generated when no RMU is installed 39948 Corrects a condition for AIT and SDLT drives that caused SAC 7C errors due to drive recovery functionality implemented in the 640 code 40727 Total wait tim
4. e for AIT drives is increased to 15 seconds to reduce the occurrence of SAC 93 errors Initial wait time is now 5 seconds If there is no response the entire command sequence is retried two more times providing 15 seconds total time before reporting a drive communication failure 42786 Systems with LTO drives now have a longer wait time to ensure that the power on self test POST completes This longer wait time eliminates SAC 96 errors that occurred on some libraries when auto inventory was turned off which resulted in shorter wait times that prevented the POST from completing 42795 Corrects a condition in which the SDLT get profile was incorrect which caused SAC 7C errors December 2006 ADIC Known Issues Due to a safety mechanism in the system if you revert to a previous firmware version for example from 641 to 630 the library resets the entire database to use the default values This safety feature protects the library against incompatibilities that might be caused by using database values from a higher firmware version when reverting to a lower firmware version Documentation The following documents are currently available for the Scalar 1000 Document Number Document Title 6 01150 01 Scalar 1000 Planning Guide 6 00054 03 Scalar 1000 Operator Guide 6 00055 02 Scalar 1000 SCSI Reference Manual December 2006 ADIC
