lstape - List tape devices
Use the lstape command to gather information about tape devices and display it in a summary format.
It gathers information about the following types of tape devices:
- CCW-attached tape devices
- Tape drive and medium charger devices that are available through the sysfs SCSI bus
For information about SCSI tape devices, the command uses the following sources for the
information displayed:
- The IBMtape or the open source lin_tape driver.
- The sg_inq command from the scsi/sg3_utils package.Note: Issuing lstape without option --ccw-only causes extra SAN traffic for each SCSI tape or changer device.
- The st (SCSI tape) device driver in the Linux® kernel.
- The ch SCSI medium changer device driver in the Linux kernel.
lstape syntax
Where:
- -s or --shortid
- strips the
0.<n>.
from the device bus-IDs in the command output. For CCW-attached devices only. - -t or --type
- limits the output to information about the specified type or types of CCW-attached devices only.
- --ccw-only
- limits the output to information about CCW-attached devices only.
- --scsi-only
- limits the output to information about tape devices that are attached to the SCSI bus.
- --online | --offline
- limits the output to information about online or offline CCW-attached tape devices only.
- <device_bus_id>
- limits the output to information about the specified CCW-attached tape device or devices only.
- -V or --verbose
- For tape devices attached to the SCSI bus only. Prints the serial of the tape and information about the FCP or virtio-scsi-ccw connection as an additional text line after each SCSI tape in the list.
- -v or --version
- displays the version of the command.
- -h or --help
- displays a short help text, then exits. To view the man page, enter man lstape.
Examples
- This command displays information about all tapes that are found, here one CCW-attached tape and
one tape and changer device that is configured for zFCP:
