Disabling Dynamic Multipathing (DMP) on VxVM

If planned maintenance on external infrastructure is scheduled, then disabling the affected paths on the hosts will avoid this issue.
Paths can be disabled using:

# vxdmpadm disable ctlr=affected_controllers

Once planned maintenance is finished, the affected paths can be enabled again using:

# vxdmpadm enable ctlr=affected_controllers

If the affected infrastructure goes down outside of scheduled maintenance, then disabling and enabling the controllers using the above commands also clears the QUIESCED state of the paths.
