# Channel Path

The Channel Path attributes contain channel configuration and performance information. Extended information is provided for FICON® channels.

Bus Percent Utilization: For FICON channels only, represents the percentage of the maximum available bus cycles being used in this collection interval.

Complex MB Second Read: For FICON channels only, represents the number of megabytes of data transferred for read requests by this channel path for all LPARs in this complex.

Complex MB Second Written: For FICON channels only, represents the average number of megabytes written by this channel path per second during this interval for the complex.

Complex Percent Read Units: For FICON channels only, represents the ratio of total read units for this channel, for the complex, divided by the maximum read units for this channel.

Complex Percent Utilized: The ratio of total channel busy time divided by elapsed time for this interval.

Complex Percent Write Units: For FICON channels only, represents the ratio of the number of write units for the complex divided by the maximum write units for this channel.

CPMF Group Number: The number of the Dynamic Channel Path Management Group to which this channel path is assigned.

DCM Status: The Dynamic Channel Path Management Status. DCM allows you to dynamically assign channels for controlling units to respond to peaks in demand.

LPAR MB Second Read: For FICON channels only, represents the number of megabytes of data transferred for read requests by this channel path for this LPAR.

LPAR MB Second Written: For FICON channels only, is the average number of megabytes written by this channel path per second during this interval for this LPAR.

LPAR Percent Read Units: For FICON channels only, is the ratio of total read units for this LPAR, divided by the maximum read units for this channel.

LPAR Percent Utilized: The ratio of channel path busy time for this LPAR divided by elapsed time for this interval.

LPAR Percent Write Units: For FICON channels only, is the ratio of total write units for this channel, for this LPAR, divided by the maximum write units for this channel.

Managed System: The SMS name of this system.

NonSMS Volumes: Represents the number of DASD volumes accessible through this channel path that are not managed by SMS.

Path ID Hex: The two-digit hexadecimal number assigned by HCD identifying this channel path to the system.

Path ID: The two-digit hexadecimal identifier for this channel path assigned by HCD.

Shared Path: Denotes whether this path is shared with other LPARs (yes), or is dedicated to this LPAR (no).

SMS Volumes: The number of SMS-controlled DASD volumes accessible through this channel path.

Status: Denotes the availability state of this channel path.

Time Stamp: The date and time this data was reported. Primarily for use in historical reporting.

Total Volumes: Represents the total number of DASD volumes accessible by this channel path.
