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
as described in the following table.
Connection
Status
Description
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.
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.
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.
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.
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.
● Data queues
● Auto-disconnect and auto-reconnect
● Pausing and resuming target processing
● Blocking writing to the target paths
● Disconnecting a connection
