CHANGES, mtx 1.2.17: - copy_barcode was off by one. - Replace garbled chars with \0 in case barcodes full of BS. Barcode changes courtesy of dirkx at covalent dot net. Set __WEIRD_CHAR_SUPPRESS to activate this code (it is not activated by default in -current.) CHANGES, mtx 1.2.16: - Fix a very special case that ADIC loaders presented to element status parser - Fix a buffer overflow w/some weird hardware, courtesy of Lars Fredricksen - Make version number include a "rel" so that the rpm will overrride a "pre" version's rpm, i.e., --version will say "mtx 1.2.16rel". - Added TapeChanger Perl package for use with Amanda to the contrib directory (see http://www.killfile.org/~tskirvin/software/tapechanger.html ) courtesy of Tim Skirvin. - Fixed spec file that was broken by 1.2.15 :-(, courtesy of Kenneth Porter CHANGES, mtx 1.2.15: - Some Solaris fixes, courtesy of Matt Ward - Fix URL in .spec file CHANGES, mtx 1.2.14: - Fix so it'll work if 0 is result of SCSI open (e.g., in cron jobs on Linux) - Move changelog to end of .spec file for easier reading - Added a bit of text to beginning of COMPATIBILITY file CHANGES, mtx 1.2.13: - Fixed some autoloader bugs w/autoloaders that don't report an arm. - Fixed barcode backoff. - Added "nobarcode" option - Increased timeout for 'mtx inventory' to 30 minutes (note: may increase this even more if needed, please let me know!) - Shortened timeout for 'mtx inquiry' to 30 seconds - tapeinfo now prints SCSI ID/LUN info if available (only on Linux at the moment, sigh). - update documentation w/new email addresses, updated compile directions, various fixes. CHANGES, mtx 1.2.12: - Fix FreeBSD compile bugs - Fix SGI compile bugs - Add HP/UX port (I hope!), courtesy of William Smith. - Re-wrote ReadElementStatus to make work for %!@# brain dead firmware that reports non-existent drives (I hope!). Also has side-effect of now working with multiple-arm libraries (though it only sees first arm!). - Cleaned up all -Wall messages. - Cleaned up Linux Sparc, installs loaderinfo.1, courtesy of Matt Dainty. - tapeinfo now reports status of CheckUnitReady. - tapeinfo no longer puts out Block Position if CheckUnitReady says 'no'. - tapeinfo now puts out Density Code and Medium Type/Not Loaded (modification of patches sent in by Bob Rahe) CHANGES, mtx 1.2.11: - Added a GNU autoconf Makefile.in (still provide a Makefile for your use) *WARNING* autoconf is not yet working on all supported OS's! You may need to do the old-fashioned 'edit Makefile' bit! - Changed mtx.h and mtxl.c to include and define various things based upon what features autoconf detected (e.g., if 'camlib.h', use FreeBSD-style 'cam', if 'scsi/sg.h' use Linux-style 'sg', etc.). If I ever port to a Unix that has same SCSI interface as one of the existing ports, autoconf will handle it without me having to add another set of #if's or #ifdefs. - Went ahead and tossed mtxctl into contrib. - In 'tapeinfo', skip \0 characters in serial numbers (some use \0 terminator, some do not, skip it if this one does). - in 'tapeinfo', dump out the block position and (if at BOP) the "BOP: Yes" flag. Also dump out other info such as block limits. - Put file 'sparc-patch1' contributed by Chaskiel M Grundman, and applied it (sigh) - Added tapeinfo.py to 'contrib' directory - Updated mtx.py in 'contrib' directory - Created 'loaderinfo' program to report some misc. info about loaders. - Created 'scsitape' program so that I don't have to keep messing with #@$%@! tape ioctls on the various Unixes that I'm porting tape software to. (But see the warnings!). - Applied the Solaris patch to the read_element_status command (sigh). - Added timeout adjustment to the SCSI subsystem. - WARNING: DIGITAL UNIX AND VMS ARE PROBABLY IRREPERABLY BROKEN, due to the timeout changes to the SCSI subsystem. If anybody wishes to fix them, feel free to send me patches. - added contrib program "mtx-changer" (an Amanda tape changer script for ?Solaris? that uses mtx rather than stc) - Jiggered Linux SCSI module for smarter error conditions handling (there are some error conditions that are normal for READ of tape drives). - Added contrib program "config_sgen_solaris.sh" which should ease setting up the 'sgen' driver on Solaris 8 (still no easy Solaris 7 or below config). CHANGES, mtx 1.2.10: - Added FAQ and COMPATIBILITY (feel free to send me patches to these files!) - Added LICENSE - Added serial number to 'tapeinfo' output. - Fixed stupid syntax error in mtx.c (compiled with gcc, not with others!) - Fixed spec file for building rpms (maybe). - Added an 'erase' command (undocumented) for use on Linux for doing short erases on tapes (the Linux device driver defaults to a long erase). - Made mtx inventory return an error code if the inventory fails, so that we can wait for inventory to be completed at system startup for libraries that auto-inventory (sigh). CHANGES, mtx 1.2.9: - Added an 'eject' command that, if directed to a tape drive, will eject the tape, and for some autoloaders, if directed to LUN 1, will eject the entire magazine. - Fixed the 'transfer' command to be 1 based rather than 0 based (sigh) - Now properly reports bar code for the tape that's in the tape drive. - Added some miscellaneous Python and Perl scripts to 'contrib'. Thanks to Frank Samuelson for the Perl scripts. CHANGES, mtx 1.2.8: - Spec file has been changed to use the "portable" patch supplied by Red Hat so it should work on Linux Alpha and Linux SPARC too... maybe... - Now will accept 4-byte element status for most element types, despite fact that these don't comply with SCSI standards :-(. This should make many older changers work, including HP optical changers. - Fixed PeripheralDeviceType table, courtesy of Rob Turk. - Now looks for CHANGER environment variable if a device is not specified on the command line. If can't find CHANGER, then tries TAPE environment variable. - Properly sets TransportElementAddress in the CDB for the MOVE MEDIUM command with what was discovered via the READ_ELEMENT_STATUS command, rather than setting them to zero (SCSI spec says that zero should be the default arm, but at least one changer out there didn't like it). - Added a '--version' command (sigh). - Added an 'inventory' command for Breece Hill libraries that don't automatically do an inventory at powerup. CHANGES, mtx 1.2.7: - Fixed problem w/single drive Exabyte 220 reporting element status data for both drives (sigh). - some general cleanup in the barcode fallback code (what a cruft!). Discovered that ADIC DAT AUTOCHANGER does not work w/mtx because it produces gibberish (will apparently only produce one element status page per request). - Fixed the RPM .spec file to have updated file locations, doc locations. - Fixed MoveMedium to say 'Output' for direction, to make it work with Solaris 8 - Some changes to the Solaris low-level module to report more errors (though it still doesn't work as well as the Linux low-level module). Should now work properly with Solaris 2.6/7/8. (Solaris changes courtesy of Richard Fish of Enhanced Software Technologies). CHANGES, mtx 1.2.6: - Fixed 'eepos' stuff to use | rather than || (whoops!) - Accept a 4-byte element descriptor for the robot arm for certain older autochangers. CHANGES, mtx 1.2.5: - Added 'noattach' command. If on command line prior to other commands, forces them to use the regular SCSI changer API rather than the _ATTACHED API, no matter what the _ATTACHED bit in the Inquiry page said. - Created 'tapeinfo' program. CHANGES, mtx 1.2.4: - Major overhaul of element guts to dynamically allocate the arrays using the result of a MODE_SENSE on the Element Address Assignment Page. If mtx 1.2.3 works for you and mtx 1.2.4 does NOT work for you, please un-comment the '#define DEBUG_MODE_SENSE' in file 'mtxl.c' and EMAIL me the results. CHANGES, mtx 1.2.3: - Fixed the source storage element number stuff (again, sigh) - Because of above fix, 'next' etc. ought to work right again. CHANGES, mtx 1.2.2: - Fixed that it was saying everything was an Import/Export element (oops!) - Properly update the Import/Export element count. CHANGES, mtx 1.2.1: - Now explicitly output that a Storage element is in fact an Import/Export element. - Added 'transfer' command to transfer between two Storage elements (so that you can get a tape to an Import/Export element. - Added 'eepos' command for controlling tray retraction on the Breecehill import/export trays. (Works with "load" and "unload" commands too, though that is not documented on "mtx -h"). CHANGES, mtx 1.2.0: - Re-numbered now that Leonard has asked me to take over maintenance of the 'mtx' program. - Temporarily treat Import/Export elements the same as Storage elements. Need to fix this eventually so that the GUI knows what kind of element we're talking about. - Removed quotes from the source element # to make it easier to parse from Perl or Python (just do a split on spaces). - Added sample program, 'mam2debug', showing how to use mtxl library for your own programs (this happens to dump the Exabyte Mammoth 2's internal debug buffer to a file, using the Mammoth2-specific SCSI commands to do so). CHANGES, mtxl 1.4.8: - Whoops, report logical rather than physical when I have to scan for open slots :-). CHANGES, mtxl 1.4.7: - Update comment to reflect mtxl 1.4.6 stuff :-). - Fix the part of the code that scans for open slots as sources for media. CHANGES, mtxl 1.4.6: - Don't use _ATTACHED interface if it reports itself as a Medium Changer! CHANGES, mtxl 1.4.5: - Changed "whoops" compile error on Linux (teach me to release w/o testing on the most popular platform!) - Changed declarations to remove compile-time warnings. CHANGES, mtxl 1.4.4: - Added support for FreeBSD. (uses pass device, NOT native FreeBSD ch device). - Change all 'int' DeviceFD to DEVICE_TYPE DeviceFD. Note that SGI and FreeBSD use a struct * to access the CAM SCSI layer, rather than a file fd. - Fixed goof where I'd hard-wired max # of elements to 127 for testing purposes (it should be sum of MAX_STORAGE_ELEMENTS + MAX_TRANSFER_ELEMENTS + MAX_TRANSPORT_ELEMENTS from mtx.h -- change those if you need more elements, bearing in mind that the code for ReadElementStatus in mtxl.c maxes out at 255 elements unless you fix that too). - Cleaned some cruft out of the MOVE_MEDIUM code. - Must have GNU Make to process Makefile. In reality, I don't know of any machine where we voluntarily use the native 'make' command, because a) there's a half dozen native 'make' all with their own perverted syntaxes, and b) most of them are brain dead beyond belief. CHANGES, mtxl 1.4.3: - Do an INQUIRY prior to doing a MOVE_MEDIUM or READ_ELEMENT_STATUS so that I can detect the MChanger bit and use MOVE_MEDIUM_ATTACHED or READ_ELEMENT_STATUS_ATTACHED commands instead. - Successfully tested with dual drives! - first, next, last now working - Created a man page - Created a 'make install', edit Makefile to alter destinations. CHANGES, mtxl 1.4.2: - Found the problem with the DAT changer! It was burping on the 'bar code' bit... so I intercept that sense key, re-issue w/out the 'bar code' bit, and success! - Added a 'TODO' file... CHANGES, mtxl 1.4.1: - Added 'invert' qualifier to 'load' and 'unload' commands to invert the media (for HP optical jukeboxes). Type './mtx' by itself to see the syntax. - Figured out why my code wasn't properly detecting errors -- turns out the 'sg' device can return ok status even when there is sense data to be reported! - Still to fix: *still* isn't working right with my Seagate 6-tape DDS-4 DAT changer... also need to put the second drive into the Exabyte 220 to make sure the dual-drive stuff works properly (!). CHANGES, mtxl 1.4: - Have now tested the barcode (volume tag) stuff. It works! (Well, there was an index-by-one problem that I had to squash, but after that...) - Changed to use SCSI Generic device API on Linux rather than SCSI_IOCTL_SEND_COMMAND API, which cut things off at 4095 bytes on i386 Linux. - Added a bunch of debugging output that needs to be ripped out :-(. Make sure you remove the -DDEBUG from the Makefile, and probably -DLONG_PRINT_REQUEST_SENSE too (unless you LIKE sense results that make sense!) - Still have annoying bug on Linux of only reading 1st 16 bytes of sense data. Alas, this appears to be a problem in the Linux 2.2 kernel, not in anything that we're doing :-(. Hmm... cdrecord has the same problem, Mr. Schilling says he's been saying it's a problem since 1997. Sigh. - Still need to test the dual-drive stuff! CHANGES, mtxl 1.3: - Hacked in the barcode (volume tag) stuff. NEED SOMEONE TO TEST WHETHER IT WORKS! - started issuing redundant initial READ_ELEMENT_STATUS with Allocation Length of 8 in order to get a BYTE_COUNT_OF_REPORT_AVAILABLE in order to calculate a better Allocation Length for the "real" READ_ELEMENT_STATUS. Trying to send a query to a small 6-tape changer with an Allocation Length suited for a 200-element tape library was resulting in some errors and lockups on the part of the tape changer device. - first, last, next, previous are STILL broken. Sorry :-(. CHANGES, mtxl 1.2: - Changed many output messages to make them more easily parsed by scripts written in awk/perl/python - Extracted out a library of SCSI tape library routines usable by "C" programs (must be GPL'ed). Extensive re-arranging of code. - Added support for multiple drives. - Started adding support for tape changers that use the "MCHangr" bit rather than a separate ID or LUN. - Increased limits so we could deal with LARGE tape libraries. - Started adding support for barcode readers in said tape libraries - broke first, last, next, previous. Sorry :-(. - Added ability to chain commands on command line. Thus could say 'mtx -f /dev/sg4 unload 4 0 load 7 0' to unload a tape from drive 0 and load the tape in slot 7 into drive 0.
