lscss - list channel subsystem devices.
- lscss <options> [RANGE]
The lscss command is used to list all or a subset of devices that are managed by
the common I/O subsystem.
Limit output to a range of subchannels by specifying multiple identifiers as a
comma-separated list or a range or a combination of both, e.g.
Note that ranges may also be separated by spaces.
- Shorten IDs by removing leading "0.0.". Note:
only IDs beginning with "0.0." will be displayed in this case.
- For IO subchannels, limit output to devices of the given
device type (e.g. 3390).
- Indicate that RANGE refers to device identifiers.
- Show availability attribute of IO devices.
- Show verified path mask. VPM is an internal path mask used
by Linux. A channel path can be used by Linux device drivers to do IO if
the corresponding bit is set in the VPM. Events that can lead to a channel
path not being available include:
- The corresponding bit is not set in at least one of the
PIM, PAM, or POM masks.
- The channel path is varied offline.
- Linux received no interrupt to IO using this channel
- Print the version of the s390-tools package and the
- Print help text.
- Print values using uppercase.
- Show IO subchannels. (default)
- Show CHSC subchannels.
- Show EADM subchannels.
- Show subchannels of all types.
List all devices that are managed by the
common I/O subsystem.
lscss -t 3390
Same as above but shows only 3390
In rare situations a device might temporarily not be accessible to the
subchannel. Then "none" is displayed as the device identifier and
the other device attributes are empty.
