This + should make us a little safer, as well as (on 2.6.x) letting us issue SCSI + commands to regular block devices as well as to /dev/sgXX devices. + WARNING: Can cause the system to *CRASH* if the SCSI device is in use, due + to brokenness inside the Linux kernel! It's always preferable to use the + /dev/sgXX device, which has specialness in its buffer handling that bypasses + some of the brokenness elsewhere in the SCSI subsystem. +- Check SG version before using SG_IO interface, so that if we're run on a + Linux 2.2 system and we were compiled on Linux 2.4 or above, +- If a tape is in the drive, make tapeinfo print out its partition info. Seems + to work on my DAT drive, anyhow (shrug). +- Minor cleanups in mtxl.c (other cleanups necessary in tapeinfo and etc.). + +CHANGES, mtx 1.3.8 +- Forgot about 8 bytes for header +- Handle pedantic loader whose firmware writer spends too much time + parsing phrases in the SCSI spec and not enough time in the + real world. + +CHANGES, mtx 1.3.6 +- The You Gotta Be F'ing Kidding Release (see rant on mailing list) +- Added AIX support with http://fz.eryx.net/aix/ GSC driver, courtesy + of Steve Heck. +- Make __WEIRD_CHAR_SUPPRESS the default to stop barcode garbling +- Fix core dump on invalid inputs in mtx.c +- Add retry with bigger ALLOCATION_LENGTH if + BYTE_COUNT_OF_REPORT_AVAILABLE is > than our original estimate. (see rant + on mailing list). +- Shut up the low-level SCSI sg_read and sg_write routines, which were poofting + all over the place on innocuous things like no EAAP. + +CHANGES, mtx 1.3.5 +- The I-Need-A-Job Release (see http://badtux.org) :-} +- Change Makefile so that it works w/systems whose 'install' program + accepts only one argument. That's it. +- Uncomment the Exabyte hack in the drive parsing code so that it works + with ATL loaders again. +- Add hack for ATL stacked loaders to keep them from reporting ghost slots + +CHANGES, mtx 1.3.4 +- Forward-ported the ATL/Exabyte patches from mtx 1.2 +- Added progress indicator to 'tapeinfo' for DAT drives. (PLEASE TEST) +- Purged a few more estinc.com out of the documentation, point to bru.com. + +CHANGES, mtx 1.3.3 +- Reversed James' long descriptor patch until can figure out what's wrong with + it. +- Fixed some debug declarations, courtesy of Kevin Wang. +- Point COMPATIBILITY file at mtx.sourceforge.net. + +CHANGES, mtx 1.3.2 +- Merged Makefile changes from mtx-1.2 code +- Changes from James Dugal to get all info for newer loaders, fix debugging + +CHANGES, mtx 1.3.1 +- add an Exchange command + +CHANGES, mtx 1.3.0 +- New Linux SCSI subsystem interface for 2.4 kernels, ripped boldly + from sgtools by Doug Gilbert +- mtx 'next' now skips blank slots, courtesy of Christopher McCrory +- mtx 'unload' now prints an error message telling you that you need to + eject the tape in the drive prior to unloading it, under certain + conditions. +- Started work on 'nsmhack' for controlling NSM jukeboxes. +- copy_barcode was off by one. +- 'position to element' command now added, courtesy of Mahlon Stacy + +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. + + |
