Dell Unity: When Replication bandwidth zero is used, SP panics when it changes to a nonzero state. (Dell Correctable)

SP Panic may occur at the timing when Replication bandwidth switches from zero to nonzero.

This event occurs under the following conditions.

(1) User snapshot replication is configured.
(2) The replication transfer contains the replication of the user snapshot.
(3) bandwidth goes to zero during the transfer of the second and subsequent snapshots.
　
　Example:
      Transfer of first user snapshot (completed) -> transfer of second user snapshot (transfer in progress).
      Transfer of first user snapshot (completed) -> transfer of system snapshot (transfer in progress).

(4) Panic occurs when the bandwidth switches from zero to nonzero.

There is an issue in the Replication temporary pause process when the isFirstXfer flag is false and the bandwidth transitions to the zero state.
The panic then occurs when the bandwidth switches from zero to nonzero and replication transfer is about to start again.

Resolution:
This issue is addressed in Unity OE 5.3.0.

Workaround:
Set the bandwidth setting to something other than zero at the time that you want to restrict Replication transfers.
