Thank-you.
It appears that the st module is loaded. #lsmod |grep st <stuff> st 32080 0
Next, I tried the command write to the tape as /dev/st0. I put a writeable tape in the drive. I have a couple of files in /root called yum_list...
tar cvf /dev/st0 /root/yum* tar: /dev/st0: Cannot open: Input/output error tar: Error is not recoverable: exiting now
The /dev/tape/by-id/... is a link pointing to /dev/st0 tar cvf /dev/tape/by-id/scsi-1HP_C7438_xxxxx /root/yum* tar: /dev/tape/by-id/scsi-1HP_C7438A_xxxxx: Cannot open: Input/output error tar: Error is not recoverable: exiting now
Running rescan-scsi-bus.sh does not help.
Running mt -f /dev/st0 offline does not do anything. mt -f /dev/st0 status SCSI 2 tape drive: File number=-1, block number=-1, partition=0. Tape block size 0 bytes. Density code 0x0 (default). Soft error count since last status=0 General status bits on (10000): IM_REP_EN
The tape drive still appears in lsscsi
