MPATH - Documentation for BMC AMI Ops SYSPROG Services 6.3

This service also detects imbalances and possible path failures by monitoring the utilization of all, or a subset of, the channel paths installed in the system.

Syntax

The parameters are defined as follows:

Parameter	Description
chpid	channel path identifier
chpid1-chpid2	range of channel path identifiers; chpid1 is the lowest channel path identifier, and chpid2 is the highest channel path identifier
time	specifies the length of the sample period in seconds; the default sample period is 15 seconds

Note

If you do not specify chpid, the MPATH service monitors all channel paths attached to all processors.

Example 1

To display I/O activity for all channel paths, type

MPATH

AMTO21I CHANNEL PATH 13 WAS 1% BUSY
AMTO21I CHANNEL PATH 1B WAS 13% BUSY
AMTO21I CHANNEL PATH 1C WAS 7% BUSY
AMTO21I CHANNEL PATH 38 WAS 14% BUSY
AMTO21I CHANNEL PATH 39 WAS 19% BUSY
