Viewing high-availability status
The Edge high-availability status on the Storage Edge Configuration page displays status for active peers serving LUNs and standby peers accepting updates from the active peer. Each status is color coded: green indicates a working state such as synchronized and current, red indicates a degraded or critical state such as a peer down, and orange indicates an intermediate or transitory state such as rebuilding the blockstore.
• Active Sync—The Edge serves client requests; the standby peer is synchronized with the current state of the active peer.
• Active Degraded—The Edge serves client requests, but the peer appliance is down.
• Active Rebuild—The Edge is updating the standby peer with updates that were missed during an outage.
• Standby Rebuild—The Edge passively accepts updates from the active peer, but its blockstore is not yet current with the state of the active peer.
• Standby Sync—The Edge passively accepts updates from the active peer and is synchronized with the current state of the system.
• Base—The Edge is starting up. The node stays in Base state when no Core appliance is configured for it and it is not connected to an HA peer.
• Dead—The Edge experienced an error from which it could not recover. The node cannot serve configuration information and its heartbeat connections are shut down.
After a persistent Edge failure, when the failed Edge rejoins the high-availability pair, its blockstore will not be active until it is synchronized with its active Edge datastore. Synchronization can take a significant amount of time, depending on the amount of data it has to synchronize. During synchronization, ESXi might mark the paths to the Edge as dead. To clear the error, manually rescan the ESXi storage after the Edge blockstore becomes active. For
