.SH DESCRIPTION
|
|
The lschp command lists status and type information about available
|
|
channel\-paths. A
|
|
.I 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
|
|
|
|
.RS
|
|
<cssid>.<id>
|
|
.RE
|
|
|
|
where <cssid> is the channel\-subsystem identifier and <id> is the CHPID\-number (e.g. 0.7e).

|
|
.RS
|
|
Indicates whether a channel\-path is shared between LPARs:
|
|
.br

0 = channel\-path is not shared
|
|
.br

1 = channel\-path is shared

.RE
|
|

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