LSCSS(8) System Manager's Manual LSCSS(8)

NAME

lscss - list channel subsystem devices.
 

SYNOPSIS

lscss <options> [RANGE]
 

DESCRIPTION

The lscss command is used to list all or a subset of devices that are managed by the common I/O subsystem.
 

[RANGE]

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.
 
0.0.1234-0.0.1235,4711
 
 
Note that ranges may also be separated by spaces.
 

OPTIONS

-s|--short
Shorten IDs by removing leading "0.0.". Note: only IDs beginning with "0.0." will be displayed in this case.
 
-t|--devtype <devtype>[/<model>][,...]
For IO subchannels, limit output to devices of the given device type (e.g. 3390).
 
-d|--devrange
Indicate that RANGE refers to device identifiers.
 
--avail
Show availability attribute of IO devices.
 
--vpm
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 path.
 
-v|--version
Print the version of the s390-tools package and the command.
 
-h|--help
Print help text.
 
-u|--uppercase
Print values using uppercase.
 
--io
Show IO subchannels. (default)
 
--chsc
Show CHSC subchannels.
 
--eadm
Show EADM subchannels.
 
-a|--all
Show subchannels of all types.
 
 

EXAMPLES

lscss
List all devices that are managed by the common I/O subsystem.
 
lscss -t 3390
Same as above but shows only 3390 devices.
 

NOTES

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.
