It appears that the st module is loaded. #lsmod |grep st

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
---- st refers to an automatic tape drive and nst refers to a manually controlled drive and most backup software prefers the usage of nst as it wants to get control over the drive and tape positioning anyway.
You might want to try...
mt -f /dev/nst0 rewind mt -f /dev/nst0 status
