lstape - list tape devices.

[<device-bus-ID>...]
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contents of /proc/tapedevices (which is obsolete) but also includes offline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.
The lstape command without the --ccw-only option causes extra SAN
traffic for each SCSI tape or changer device by invoking the sg_inq
command.
- -h or --help
- Print help text.
- -v or
--version
- Print the version of the s390-tools package and the command.
- -V or
--verbose
- Adds additional information that does not fit into a single line of
output. This is currently only used for SCSI devices.
- --scsi-only|--ccw-only
- 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.
- -s|--shortid
- 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.
- --online|--offline
- Limit output to either online or offline devices. This filter has no
effect on the output of SCSI devices.
- -t|--type
<device-type>
- Limit output to given device types, for example 3490 (currently only
applies to channel-attached tape devices).
- <device-bus-ID>
- Limits the output to information about the specified tape device or
devices only. For CCW-attached devices only.
- Generic
- SCSI generic device file for the tape drive, for example /dev/sg0.
"N/A" if the SCSI generic (sg) kernel functionality is not
available.
- Device
- Main character device node file for accessing the tape drive or medium
changer. SCSI tape devices 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. The lstape command tries to determine the device driver. 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 device driver could not be determined.
- Target
- Linux SCSI device name in H:C:T:L format.
- Vendor
- The vendor field from the SCSI device.
- Model
- The model field from the SCSI device.
- Type
- "tapedrv" for a tape drive or "changer" for a medium
changer.
- State
- The state of the SCSI device object in the kernel. Any state other than
"running" can indicate problems.
For SCSI devices, the --verbose option additionally displays:
- HBA
- The device bus-ID of the FCP device or of the virtio-scsi-ccw virtual HBA
through which the tape drive is attached. "N/A" if the device
does not have a sysfs ancestor with subsystem ccw.
- WWPN
- The WWPN (worldwide port name) of the tape drive in the SAN.
"N/A" if device is not attached through zfcp.
- Serial
- The serial number. "NO/INQ" if there is no sg_inq command
available. "NO/SG" if no SCSI generic (sg) kernel support is
available.
lstape
List all tape devices that are available
lstape --ccw-only -t 3490 --online
Show all 3490 CCW devices that are online.
lstape --scsi-only --verbose
Show all SCSI tape or changer devices with maximum
information.
