When we attempt to use tar to write data to an LTO-5 tape, we get the following error. The device starts to write, and then fails. See the tar command and output, followed by the dmesg output. I included the mt status as well. Any help is appreciated.This is an Ultrium 3280 LTO5 drive connected through a SAS interface on RHEL 6. We tried a second drive, and second tape. These are brand new tapes, and new drives.Both of the following commands run without any issues.sudo mt -f /dev/st0 stsetoptions scsi2logicalsudo mt -f /dev/st0 erasemt status provides the followingsudo mt -f /dev/st0 statusSCSI 2 tape drive: File number=0, block number=0, partition=0.Tape block size 0 bytes.Density code 0x58 (no translation).Soft error count since last status=0General status bits on (41010000): BOT ONLINE IM_REP_ENWhen we attempt to write some output to the drive, we get the following. The device acts as if it is writing, lights start flashing and starts making noise.sudo tar cvf /dev/st0 /vadertar: Removing leading `/' from member names/vader//vader/data0905a-data0906//vader/data0905a-data0906/data0905a-FINAL//vader/data0905a-data0906/data0905a-FINAL/data0905a.trk/vader/data0905a-data0906/data0905a-FINAL/plots//vader/data0905a-data0906/data0905a-FINAL/plots/0905A_trak.ps/vader/data0905a-data0906/data0905a-FINAL/plots/0905A_trak.jpg/vader/data0905a-data0906/data0905a-FINAL/das//vader/data0905a-data0906/data0905a-FINAL/das/uw//vader/data0905a-data0906/data0905a-FINAL/das/uw/0905tmp.tar/vader/data0905a-data0906/data0905a-FINAL/das/uw/0905nud.tar/vader/data0905a-data0906/data0905a-FINAL/das/uw/0905das.tar/vader/data0905a-data0906/data0905a-FINAL/das/uw/0905wnc.tar/vader/data0905a-data0906/data0905a-FINAL/das/uw/0905bdp.tar/vader/data0905a-data0906/data0905a-FINAL/das/uw/0905vp1.tar/vader/data0905a-data0906/data0905a-FINAL/das/uw/0905rv1.tar/vader/data0905a-data0906/data0905a-FINAL/das/uw/0905tsg.tar/vader/data0905a-data0906/data0905a-FINAL/das/uw/0905co2.tar/vader/data0905a-data0906/data0905a-FINAL/das/uw/0905guv.tar/vader/data0905a-data0906/data0905a-FINAL/das/uw/0905ng1.tar/vader/data0905a-data0906/data0905a-FINAL/das/uw/0905wx1.tar/vader/data0905a-data0906/data0905a-FINAL/dcp//vader/data0905a-data0906/data0905a-FINAL/dcp/0905dcp.tartar: /dev/st0: Cannot write: Input/output errortar: Error is not recoverable: exiting nowHere is dmesgmptbase: ioc0: LogInfo(0x31120403): Originator={PL}, Code={Abort},SubCode(0x0403) cb_idx mptscsih_io_doneLSI Debug log info 31120403 for channel 0 id 2st0: Error 80000 (driver bt 0x0, host bt 0x8).Does anyone have any ideas or suggestions?
