Storage Status

This page details the status of storage volumes and iSCSI LUNs (Block-Level) on the active and passive servers of the high-availability cluster.

Because the capacity and configurations of the corresponding volumes and iSCSI LUNs (Block-Level) on the active and passive servers must be identical, the volumes and iSCSI LUN (Block-Level) on the two servers are displayed together as single units. Therefore, if you wish to view the status of volumes and iSCSI LUNs (Block-Level) of both the active and passive servers, you must go to the Storage Status page [when accessing a high-availability cluster, only volumes and iSCSI LUNs (Block-Level) on the active server are viewable in Storage Manager].

This page contains the following information:

To repair a malfunctioning volume or iSCSI LUN (Block-Level):

Note: The limit of volumes and iSCSI LUNs (Block-Level) on a high-availability cluster is 64.

Quorum Server

Quorum servers can help reduce the possibility of split-brain errors. In split-brain settings, you can assign another server as the quorum server, as long as it constantly connects to both the active and passive servers. For example, a gateway server or DNS server is a suitable choice for quorum server because it can connect to both the active and passive servers. Please note that quorum server is to provide Ping services only, and no applications are required to be installed. Below are circumstances that will follow when quorum server is enabled:
