What is a requirement for a running HCP system to maintain quorum for cluster operations?

Aminimum 50% of the nodes

Bminimum 50% of the nodes + quorum LUN

Cminimum 50% of the nodes + Command Device

Dminimum 50% of the nodes + 1 node

Show Suggested Answer

Suggested Answer: D

For a running HCP (Hitachi Content Platform) system to maintain quorum for cluster operations, a majority of nodes must be operational. Specifically, this means that at least 50% of the nodes + 1 node must be available to achieve quorum. Quorum is necessary to maintain consistency, availability, and coordination among the nodes in the cluster, ensuring that the cluster can continue operating correctly in case of node failures. This configuration avoids split-brain scenarios where multiple parts of the cluster operate independently.

Hitachi Vantara Content Platform Installation Reference:

The quorum requirement is designed to ensure that a majority of nodes are always participating in cluster operations, providing a safeguard against data corruption and ensuring high availability.
