IBM tape devices are interfaced with the lin_tape device driver and is loaded as a Linux kernel module. Servers that require access to tape devices include Tivoli Storage Manager (for server or storage agents) or IBM Spectrum Archive. The lin_taped daemon creates the special device files that correspond to the tape devices.
After the lin_tape module is loaded, you can see all attached tape devices with /proc/scsi/IBMtape:
## On a TSM server with access to only LTO7 drives:
[root@tsm ~]# cat /proc/scsi/IBMtape
lin_tape version: 3.0.18
lin_tape major number: 243
Attached Tape Devices:
Number model SN HBA SCSI FO Path
0 ULT3580-TD7 00078D15CE lpfc 1:0:0:0 Primary
1 ULT3580-TD7 00078D15D3 lpfc 1:0:1:0 Primary
2 ULT3580-TD7 00078D1255 lpfc 1:0:2:0 Primary
3 ULT3580-TD7 00078D12D2 lpfc 1:0:3:0 Primary
4 ULT3580-TD7 00078D15CE lpfc 2:0:0:0 Alternate
5 ULT3580-TD7 00078D15D3 lpfc 2:0:1:0 Alternate

13 ULT3580-TD7 00078D1255 lpfc 4:0:3:0 Alternate
## On a LTFSEE server with access to LTO8 drives on the same tape library:
[root@ltfs ~]# cat /proc/scsi/IBMtape
lin_tape version: 3.0.52
lin_tape major number: 240
Attached Tape Devices:
Number model SN HBA SCSI FO Path
0 ULT3580-TD8 000780765B qla2xxx 5:0:0:0 Primary
1 ULT3580-TD8 000780765B qla2xxx 3:0:0:0 Alternate
2 ULT3580-TD8 0007807A0B qla2xxx 3:0:1:0 Primary
3 ULT3580-TD8 0007807A4B qla2xxx 3:0:2:0 Primary
4 ULT3580-TD8 0007807A0B qla2xxx 5:0:1:0 Alternate
5 ULT3580-TD8 0007807A4B qla2xxx 5:0:2:0 Alternate
Additionally, the tape changers can be viewed with cat /proc/scsi/IBMchanger.
[root@tsm ~]# cat /proc/scsi/IBMchanger
lin_tape version: 3.0.18
lin_tape major number: 243
Attached Changer Devices:
