NAME

lschp - list information about available channel-paths.

SYNOPSIS

lschp [-h|--help] [-v|--version] [ CHPID ]

DESCRIPTION

The lschp command lists status and type information about available channel-paths. A CHPID argument can be specified to return the information for the respective channel-path identifier only. Channel-path identifiers are specified in hexadecimal notation either simply as the CHPID-number (e.g. e0) or in the form

<cssid>.<id>

where <cssid> is the channel-subsystem identifier and <id> is the CHPID-number (e.g. 0.7e).

Column description:

CHPID

Channel-path identifier.

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-ID unless the 4-digit hexadecimal value is enclosed in parenthesis.

If the value is enclosed in parenthesis, no physical channel-ID is associated with the CHPID, and the value is an internal channel-ID.

For example, 0501 specifies a PCHID whereas (0502) specifies an internal channel-ID.

A column value of '-' indicates that a facility associated with the respective channel-path attribute is not available.

OPTIONS
