- ONTAP 9
- Fabric Pool
- An ONTAP node that owns an aggregate using fabric pool and the hosts see the LUNs but are unable to access the data.
- Host logs show a medium error
In this example VMware vmkernel logs show a medium error when trying to access a LUN.

If ONTAP shows the node owning the aggregate such as below, the issue is ObjectStore connectivity related.
