"VCS ERROR V-16-10031-5010 (%SERVER%) IPMultiNIC:%RESOURCE_NAME%:monitor:Could not open active device file (/var/VRTSvcs/lock/.mnic_dev_active_mnic_1): No such file or directory" is reported by an IPMultiNIC resource

Problem

An error is reported by the IPMultiNIC resource when a probe is attempted.

Error Message

VCS ERROR V-16-10031-5010 (%SERVER%) IPMultiNIC:%RESOURCE%:monitor:Could not open active device file (/var/VRTSvcs/lock/.mnic_dev_active_mnic_1): No such file or directory

Cause

This error appears if the The “MultiNICAResName” attribute of the IPMultiNIC resource is pointing to a regular NIC resource. When the IPMultiNIC resource attempts to probe, it looks for a file that is supposed to be created by the MultiNICA/B resource. In this case, the file doesn’t exist because the regular NIC resource does not create this file.

Solution

Replace the IPMultiNIC with a regular IP resource, or replace the NIC with a MultiNIC resource. A regular NIC resource should be paired with a regular IP resource, and a MultiNIC should be paired with an IPMultiNIC.
