lschp - List channel paths
Use the lschp command to display information about channel paths.
lschp syntax
where:
- <chpid>
- limits the output to the specified channel path ID (CHPID). Specify CHPIDs as a two-digit
hexadecimal number with or without
0.as a prefix. - -v or --version
- displays the version number of lschp and exits.
- -h or --help
- displays out a short help text, then exits. To view the man page, enter man lschp.
Output column description:
- CHPID
- Channel-path identifier with a
0.prefix. - Vary
- Logical channel-path state:
- 0 = channel-path is not used for I/O.
- 1 = channel-path is used for I/O.
- Cfg.
- Channel-path configure state:
- 0 = stand-by
- 1 = configured
- 2 = reserved
- 3 = not recognized
- Type
- Channel-path type identifier.
- Cmg
- Channel measurement group identifier.
- Shared
- Indicates whether a channel path is shared between LPARs:
- 0 = channel path is not shared
- 1 = channel path is shared
- PCHID
- Physical channel path identifier, or, if enclosed in brackets, internal channel identifier. The
mapping might not be available to Linux® when it is running
as a z/VM® guest. If so, use the CP command:
QUERY CHPID <num> PCHID
A column value of '-' indicates that a facility associated with the corresponding channel-path attribute is not available.
Examples
- To query the configuration status of channel path ID 40 issue:
The value under Cfg. shows that the channel path is configured (1).# lschp 40 CHPID Vary Cfg. Type Cmg Shared PCHID ====================================== 0.40 1 1 1b 2 1 0580
