Connections
A unique connection ID is associated with each Storage Mirroring Recover connection.
The connection ID provides a reference point for each connection. The connection ID is
determined by sequential numbers starting at one (1). Each time a connection is
established, the ID counter is incremented. It is reset back to one each time the Storage
Mirroring service is restarted. For example, if the Storage Mirroring service was started
and the same replication set was connected to five target machines, each connection
would have a unique connection ID from 1 to 5. The connection can be in various states.
l
Started—The network connection exists and is available for data transmission.
Replication and mirror data are transmitted to the target as soon as possible. This
is the standard state that you will see most often.
l
Stopped—Storage Mirroring Recover has linked the source and target, but the
network connection does not exist. Replication and mirror data are not transmitted
to the target but are held in queue on the source.
l
Paused—The network connection exists and is available for data transmission,
but the replication and mirror data is being held in a queue and is not being
transmitted to the target.
l
Scheduled—Storage Mirroring Recover has linked the source and target, but the
network connection is not established until event driven or scheduling criteria have
been met.
l
Error— A transmission error has occurred. Possible errors include a broken
physical line or a failed target service.
You can perform the following functions to manage your connections.
