Replication destination volume is detached, Replication disconnection, Replication incompatible versions – Dell PowerVault NX3600 User Manual
Page 83: Replication internal error

Workaround
The replication continues automatically when the space is
available. The administrators must verify that the
replication automatically continues after a period of time
(an hour).
Replication Destination Volume Is Detached
Description
Replication between the NAS source volume and the NAS
destination volume fails because the NAS destination
volume is detached from the NAS source volume.
Cause
Replication task fails because the destination NAS volume
was previously detached from the source NAS volume.
Workaround
The administrators must perform the detach action on the
NAS source volume. If required, reattach both NAS
volumes in a replication relation.
Replication Disconnection
Description
Replication between the NAS source volume and the NAS
destination volume fails because the connection between
source and destination systems is lost.
Cause
Network infrastructure disconnection between the source
and the destination.
Workaround
The administrator must check if the replication is
automatically restored. If the replication is not
automatically restored, check the network communication
between the source cluster and the destination cluster.
Network communication can be checked by using a third
party system in the same subnet that can ping both the
source and destination clusters.
Replication Incompatible Versions
Description
Replication between the NAS source volume and the NAS
destination volume fails because the system version of the
source NAS cluster is higher than the system version of
the destination cluster.
Cause
Replication task fails since the system version of the
source NAS cluster is higher than the system version of
the destination cluster.
Workaround
Administrators must upgrade the system version of the
destination cluster to match the system version of the
source cluster.
Replication Internal Error
Description
Replication between the source and the destination NAS
volumes fails due to an internal error.
