AdvancedCopy Manager CCM supports the following Advanced Copy functions. Note that Advanced Copy is executed for each separate logical volume of ETERNUS Disk storage system.
Advanced Copy Function | AdvancedCopy Manager | AdvancedCopy Manager CCM | ||
|---|---|---|---|---|
Snapshot type high-speed copies | OPC | A | A | |
QuickOPC | A | A | ||
SnapOPC | A | N/A | ||
SnapOPC+ | A | A | ||
Synchronous high-speed copies | EC | Reversing the copy direction | A | A |
Concurrent suspend function | A | A | ||
REC | Reversing the copy direction | A | A | |
Initial copy skip function | A | A | ||
Concurrent suspend function | A | A | ||
Displaying or changing information about the REC transfer buffer | A | A | ||
(A=Available, N/A=Not Available)
Note
If using AdvancedCopy Manager and AdvancedCopy Manager CCM together, make sure that they control different logical volumes and that the logical volumes do not interact.

AdvancedCopy Manager CCM can be operated on the cluster environment.
Refer to the ETERNUS SF Cluster Environment Setup Guide for more information.
The following functions are supported in the Storage Cluster environment. Select the appropriate one according to your purpose.
Advanced Copy to a volume (hereafter called "non-TFOV") which is not a target of the Storage Cluster function from a TFOV
Advanced Copy from a TFOV to a TFOV by using the Storage Cluster Continuous Copy function
Advanced Copy Function | From TFOV to non-TFOV | From TFOV to TFOV | |
|---|---|---|---|
Snapshot type high-speed copies | OPC | A | A |
QuickOPC | A | A | |
SnapOPC | N/A | N/A | |
SnapOPC+ | A | N/A | |
Synchronous high-speed copies | EC | A | A |
REC | A | N/A | |
(A=Available, N/A=Not Available)
Point
When performing an inter-box copy from a TFOV to a non-TFOV, restore of a TFOV is not possible if the TFO status is "Standby" due to a failover or a failback. The Storage Cluster Continuous Copy function can continue Advanced Copy or restore even if a failover or failback occur. For this reason, we recommend using the Storage Cluster Continuous Copy function.
Use Advanced Copy from a TFOV to a non-TFOV for a temporary backup, etc.
When performing an inter-box copy, use REC from a TFOV to a non-TFOV.
See
For how to perform Advanced Copy from a TFOV to a non-TFOV, refer to "3.11 Operations of Advanced Copy Using TFOV".
For how to perform Advanced Copy from a TFOV to a TFOV by using the Storage Cluster Continuous Copy function, refer to "3.12 Storage Cluster Continuous Copy Function".
