Issue
- During an ONTAP update all LUN's homed on HA node, host lost access
- Ports and LIF's are up and no link issues detected
- ESXi setup as per best practices
- ESXi host shows only paths to same single HA node, missing paths to impacted node
- Cisco switch does not contain zoning information for LIF/port connected to it.
