A customer has a 4-node cluster and wants to know what will happen to their data if one of the two
HA pairs goes down. Epsilon is configured and working properly and is owned by Node1. Nodes 3
and 4 have failed as shown in the exhibit.
What happens to the customer’s data that is owned by the HA pair 3 and 4?
A.
Nodes 1 and 2 will takeover the storage for nodes 3 and 4 and continue running normally.
B.
The cluster will go into maintenance mode and only allow administrators access to data on
nodes 1 and 2.
C.
The entire cluster will panic and no data will be accessible.
D.
The customer will lose access to the data on nodes 3 and 4 but will still have access to storage
in nodes 1 and 2.
Explanation:
An HA pair is two storage systems (nodes) whose controllers are connected to each
other directly. In this configuration, one node can take over its partner’s storage to provide
continued data service if the partner goes down. Clustered Data ONTAP 8.3, High-Availability Configuration Guide, page 7
A is wrong answer.
True is D.
Node 3 and node 4 – HA pair. If both nodes have failed – the customer will lose access to storage data.
