INSYNC

The target ASP copy has been synchronized with its source. The two copies are identical to each other. This can only occur when the source copy has been varied off.

UNUSABLE

The data in the ASP copy is not in a usable state. Either synchronization has not yet been completed, or the mirror copy node had an abnormal termination that requires synchronization.

USABLE

The data in the ASP copy is in a usable state. If *ASYNC mirroring mode has been selected, the mirror copy is usable unless an abnormal termination of the mirror copy occurs before the mirror copy of the ASP can be quiesced.

Nullable

For ASP Geographic Mirroring contains the round-trip time in microseconds. Round-trip time represents the period of time when data is written to the storage on the production copy until that same data is acknowledged by the mirror copy node. For asynchronous transmission delivery, this indicates how far behind the mirror copy node is or could be. Regardless of transmission delivery, this estimates the impact of the network on the performance of geographic mirroring.

Round-trip time is influenced by factors including:

• Physical distance between the production and mirror nodes

• Latency between the nodes
