Test Description

The case checks whether Veritas Dynamic Multipath (VxDMP) is enabled alongside the Solaris native Multipath service (MPxIO). If both are enabled, specific configuration settings must be set (see: Oracle Knowledge Base article).

This test case fails if:

Both MPxIO and the VxDMP are enabled on the host, and at least one of VxDMP tunable settings is not correctly set to enable work alongside MPxIO.

This test case passes if:

VxDMP is configured to work correctly alongside MPxIO.

How to fix this test

Automatic fix

The tool attempts to set the relevant VxDMP tunable settings to the values which enable work alongside MPxIO.

Manual fix

Set the relevant VxDMP tunable settings using the vxdmpadm settune command:

vxdmpadm settune dmp_fast_recovery=0
vxdmpadm settune dmp_health_time=0
vxdmpadm settune dmp_path_age=0
vxdmpadm settune dmp_lun_retry_timeout=200

These settings are based on the recommended settings in the Oracle Knowledge Base, which can be found here.
