VCF on VxRail: Node Add Validation Failed if the management network load balancing policy is "Route based on IP hash"
Summary: VxRail does not support the route based on IP hash load-balancing policy, day2 node add validation fails if the management port group chooses that policy.
Symptoms
VxRail does not support the route based on IP hash load-balancing policy, but in VCF on VxRail environment, when adding a Workload Domain (WLD) from SDDC UI, the user can select that policy and deploy the Virtual Infrastructure Workload Domain (VI WLD) cluster successfully.
However, day2 node add validation fails due to a VLAN validation error.
Cause
VxRail does not support "route based on ip hash" load-balancing policy.
Static link aggregation group (LAG) cannot be used for system port groups including "management," " vxraildiscovery" and "vxrailsystemvm" port groups.
Resolution
Modify the Management Network port group load-balancing policy to a VxRail supported policy.
The following example chooses the "Route based on originating virtual port" load-balancing policy and active/standby failover policy.
-
Log in to vCenter UI, edit the Management Network port group.
-
Change the load balancing to "Route based on originating virtual port" and set only one uplink as "Active."
-
Retry the node add validation.
