Channel Paths Attributes

The Channel Paths Attribute group provides information about the utilization of a channel path.

Cluster Name The name of the LPAR Cluster to which the host LPAR is assigned. The name corresponds to the I/O Cluster to which the Channel Path is assigned. The format for the name is xxxxxxxx.ssss.tttt, where:

This format is consistent with the Cluster Name provided in the LPAR Clusters workspace. A value of N/A is provided if the channel path is not managed by Dynamic Channel Path Management (DCM). Valid value is an 18-byte character string.

Complex Percent The percentage of time that the channel was busy within the complex. Valid value is a 4-byte integer in the range 0.0 to 100.0.

Configured A description of how the channel path was reconfigured during the RMF interval. Valid values:

CPMF The Channel Path Measurement Facility (CPMF) calculates channel path utilization. Valid values are:

DCM Status Indicates whether Dynamic Channel Path Management (DCM) is enabled for this channel path. It is possible that the Intelligent Resource Director (IRD) can change the channel's configuration to help meet Workload Manager goals. Valid values are YES or NO.

LPAR Percent The percentage of time the channel was busy working for the logical partition. This column can be blank or non-blank. The column is blank when: a) the system is running in basic mode; b) the channel path is offline; c) the ESCON Multiple Image Facility (EMIF) is not installed; or d) CPMF is unavailable or not installed.

Valid values range from 0 to 100% when the system is running in LPAR mode, EMIF is installed, and the channel path is online. If the channel path is shared, this value represents the LPAR's utilization of the channel path from the start of the RMF interval. If the channel path is not shared, the LPAR utilization value is the same as the complex-wide utilization value.

This value can be greater than the utilization of the channel by the entire complex, since the LPAR value is obtained from the hardware, whereas the Complex value is sampled and may not include channel utilization.

Managed System An z/OS operating system in your enterprise that a Tivoli OMEGAMON XE for z/OS agent is monitoring. Valid value is a character string with a maximum length of 32 bytes.

Mode The mode of the channel path. Valid values are:

Online An indicator showing whether the channel is online (Y) or offline (N). Valid values are Y or N.

Path ID The channel path ID. Valid value is 1-byte hexadecimal.

RMF Interval Start The time in HH:MM:SS format when the current RMF interval started.

Sample Count The number of samples in this measurement interval. Valid value is a 4-byte integer.

Shared An indicator indicating whether the channel is shared with other logical partitions. Only ESCON channels (ESchn) or directors (ESdir) can be shared channels. Valid values are Y or N.

Type The channel data type. Some of the valid values are shown below. Because the list of possible values is long and changes often, please refer to IBM's RMF Report Analysis Manual for the most current list.
