Open Replicator is a non-disruptive migration and data mobility application.
Depending on the operation that you are performing, some of the following options may not apply.
Session Option
Used with UI operation
Description
Consistent
Activate
This option causes the volume pairs to be consistently activated.
Donor Update Off
Consistently stops the donor update portion of a session and maintains the consistency of data on the remote volumes.
Copy
Create
Volume copy takes place in the background. This behavior is the default for both pull and push sessions.
Cold
Create
Control volume is write-disabled to the host while the copy operation is in progress. A cold copy session can be created provided one or more directors discovers the remote device.
Differential
Create
This option creates a one-time full volume copy. Only sessions that are created with the differential option can be recreated.
For push operations, this option is selected by default.
For pull operations, this option is cleared by default (no differential session).
Donor Update
Create
This option causes data that is written to the control volume during a hot pull to also be written to the remote volume.
Incremental Restore
Maintains a remote copy of any newly written data while the Open Replicator session is restoring.
Force
Terminate
Restore
Select the
Force option if the copy session is in progress. This option allows the session to continue to copy in its current mode without donor update.
Donor Update Off
Select the
Force option if the copy session is in progress. This option allows the session to continue to copy in its current mode without donor update.
Force Copy
Activate
This option overrides any volume restrictions and allows a data copy.
For a push operation, remote capacity must be equal to or larger than the control volume extents and conversely for a pull operation. The exception to this rule is when you have pushed data to a remote volume that is larger than the control volume, and you want to pull the data back, you can use the
Force_Copy option.
Front-End Zero Detection
Create
This option enables front end zero detection for thin control volumes in the session. Front end zero detection looks for incoming zero patterns from the remote volume, and instead of writing the incoming data of all zeros to the thin control volume, the group on the thin volume is de-allocated.
Hot
Create
Hot copying allows the control device to be read/write online to the host while the copy operation is in progress. All directors that have the local devices mapped are required to participate in the session. A hot copy session cannot be created unless all directors can discover the remote device.
Nocopy
Activate
Temporarily stops the background copying for a session by changing the state to CopyOnAccess or CopyOnWrite from CopyInProg.
Pull
Create
A pull operation copies data to the control device from the remote device.
Push
Create
A push operation copies data from the control volume to the remote volume.
Precopy
Create
Recreate
For hot push sessions only, begins immediately copying data in the background before the session is activated.
SymForce
Terminate
Forces an operation on the volume pair including pairs that would be rejected. Use caution when checking this option because improper use may result in data loss.
