Applies to

• FAS
• AFF

Issue

A node may appear to have all of the cabling in place for Quad-Path HA, but the nodes will report as Mixed-Path in Sysconfig -a:

System ID: 0537152622 (Hostname1); partner ID: 0537152611 (hostname2)
    System Serial Number: 721748000127 (hostname)
    System Rev: A0
    System Storage Configuration: Mixed-Path

The nodes may also continuous Asyncd device scan done messages in the EMS logs:
