One Metro Volume witness may be configured per PowerStore appliance. The witness-related configuration is available in PowerStore Manager Protection > Metro Witness. This page allows the addition of a new witness and shows the currently configured witness service.
There are five possible Metro Volume witness connection states:
- OK – This is the normal operating condition. All nodes on all appliances can communicate with the witness.
- Partially Connected – Some nodes on some appliances can communicate with the witness. The same witness may not be registered on the peer PowerStore.
- Disconnected – All nodes on all appliances cannot communicate with the witness.
- Deleting – The witness is currently being unregistered and deleted from the cluster. This state may persist if the delete operation fails. In that case, the delete can be retried.
- Initializing – All nodes on all appliances are initializing their connection to the witness. This is the initial state of the witness when first added to the PowerStore.
