Sometimes the machine freezes after a few minutes into tape access and sometimes it works days - or even weeks - without any problem. The bug only appears during tape I/O (regardless of which tape program is used: btape, dd or tar). In most cases the tape write ends with an input/output error. After this error occurred, any access to the tape library robot (connected through the SAS interface of the first drive) fails: # mtx unload 1 1 Unloading drive 1 into Storage Element 1...mtx: Request Sense: Long Report= =3Dyes mtx: Request Sense: Valid Residual=3Dno mtx: Request Sense: Error Code=3D70 (Current) mtx: Request Sense: Sense Key=3DIllegal Request mtx: Request Sense: FileMark=3Dno mtx: Request Sense: EOM=3Dno mtx: Request Sense: ILI=3Dno mtx: Request Sense: Additional Sense Code =3D 53 mtx: Request Sense: Additional Sense Qualifier =3D 01 mtx: Request Sense: BPV=3Dno mtx: Request Sense: Error in CDB=3Dno mtx: Request Sense: SKSV=3Dno MOVE MEDIUM from Element Address 257 to 4096 Failed After resetting the scsi bus (echo "- - -" > /sys/class/scsi_host/host5/scan) the tape drives are revitalized, but the changer device disappears. Even after a cold restart of the whole library the device keeps missing. Yet another problem: restting the SCSI bus of the LSI SAS HBA sometimes results in a hardy freeze (console stuck; no log messages). > [...] > >I do not believe it's a hardware fault at the moment as the machine >ran OK under Solaris for a few weeks (including successful btape runs). > The very same piece of hardware worked fine using Solaris 10 with heavy disk and tape I/O at the same time for two months. We really prefer using Linux instead, but we're in pressure of time. We appreciate any help resolving this bug!

OK. In data corruption condition only LSI driver and controller are involve= d?
