Table 2‒4: Cluster status
Cluster status		Description
Status	Status displayed by the eztool status command	Description
Cluster is available	`AVAILABLE`	The cluster is running normally.
Cluster is partially available	`PARTIALLY_AVAILABLE`	The cluster is partially running. The cluster might not be accessible depending on the key. If the number of EADS servers that make up the cluster is at least the data multiplicity 2 - 1, the cluster might be placed in this status if more EADS servers are shut down than there are data copies plus the original. Once the cluster is placed in this status, it cannot be placed in `AVAILABLE` (cluster available) status unless all EADS servers are stopped.
Cluster is unavailable	`NOT_AVAILABLE`	The cluster is not running. The cluster is placed in this status in either of the following cases: Split-brain occurred. At least half of the EADS servers in the cluster are shut down. Once the cluster is recovered from split-brain, it can be placed in `AVAILABLE` status (cluster available) or `PARTIALLY_AVAILABLE` (cluster partially available).
