Hello, I'm experiencing a problem on a machine running Sun's Solaris. It's an x86 machine running Solaris 10:
# uname -a SunOS blah.domain.tld 5.10 Generic_137138-09 i86pc i386 i86pc The machine is running Bacula version 2.2.8 (yes, I know it's outdated, but that's what blastwave offers, and compiling is not an option currently...). The tape library is a two-drive Qualstar one using AIT-5 drives connected to a parallel-SCSI HBA. Some times - not easily reproduced - the tape drive or autochanger seems to have problems like these: 16-Apr 02:49 blah-sd JobId 2097: Error: block.c:569 Write error at 472:3118 on device "AIT5-drv1" (/dev/rmt/1cbn). ERR=I/O\ error. 16-Apr 02:49 blah-sd JobId 2097: Error: Error writing final EOF to tape. This Volume may not be readable. dev.c:1669 ioctl MTWEOF error on "AIT5-drv1" (/dev/rmt/1cbn).

Unfortunately, as also seen, it also affects the autoloader which can't unload the tape. In the system log, I find errors like these at that times: Apr 27 20:40:04 blah.domain.tld itmpt: [ID 556182 kern.info] itmpt0: target 2 fallback from Ultra Wide to Ultra Narrow *** this seems to indicate a serious SCSI problem, probably hardware-related.

The HBA has been replaced. Mtx typically works correctly, only after things are broken some manual intervention is required, i.e. the library needs a pwer-cycle or manual unloading of the affected cartridge. There is no pattern I can see regarding the tape cartridges, but I'm quite sure the problem always affects the same drive (though those two drives are not necessarily evenly loaded). I think it's either a hardware problem with the tape library, or a SCSI related driver issue. As I neither have another Qualstar or AIT device here, nor an other Sun machine for comparison, I'd like to know if any of you have seen similar problems. Or know better than I do what Solaris is actually complaining about :-) Some advice which manufacturer - Sun or Qualstar - to first contact would also be appreciated!
