lstape - list tape devices.
The lstape command lists all available tape devices on the current host. For
channel attached tape devices this output is the same as the contents of
/proc/tapedevices (which is obsolete) but also includes offline devices. By
default all tape devices are displayed.
Since SCSI tape devices are accessed differently to channel attached tape
devices they are only visible if they are known to the SCSI layer. There are
at least two possible drivers that can claim a SCSI tape device and the lstape
command tries to find out which one this is. For the generic tape and changer
driver the device names start with "st" or "sch", while
for the IBM tape driver this would be "IBMtape" or
"IBMchanger". If "N/A" is shown, the correct driver could
not be obtained. This happens for example if there is no sg_inq command
installed which is required to read the drive's serial number which in turn is
used to find out the device number of the IBM tape driver.
The serial number of a SCSI tape can be displayed with the --verbose option. If
there is no sg_inq command available "NO/INQ" is shown as the tape's

- Print help text.
- -v or --version
- Print the version of the s390-tools package and the

- Adds additional information that does not fit into a single
line of output. This is currently only used for SCSI devices.
- Limit output to either SCSI or channel attached tape
devices. The output without SCSI devices is the same as it was with
previous versions of this command.
- Using this option will list only tape devices that are in
channel subsystem 0, with subchannel set 0. All other devices will be
suppressed and the leading "0.0." for bus IDs of the remaining
devices will be removed. Since this is specific to CCW devices this option
has no effect on the output of SCSI tape devices.
- Limit output to either online or offline devices. This
filter has no effect on the output of SCSI devices.

- Limit output to given device types (currently only applies
to channel attached tape devices).
