Chapter 8 Advanced Copy Management
8.2 Functions in the Action Area for Advanced Copy
The following ETERNUS DX Disk storage systems support the [Set Copy Path] function.
•
ETERNUS DX90 S2
•
ETERNUS DX410 S2/DX440 S2
•
ETERNUS DX90
•
ETERNUS DX410/DX440/DX8100/DX8400/DX8700
•
ETERNUS4000/ETERNUS8000
In this section, the device used as the copy path standard is referred to as "local device" and the
storage system to be connected as a "remote device".
The following settings are available for the [Set Copy Path] function:
(1) Register Device Information (Register)
(2) Create Copy Path (Create)
(3) Save (Save)
(4) Apply Copy Path (Apply)
(5) Measure Round Trip Time (Measure)
•
To create copy path information between different models of ETERNUS
DX Disk storage systems (such as ETERNUS DX440 S2 and
ETERNUS4000), be sure to create the information on the newer model
of ETERNUS DX Disk storage system (ETERNUS DX440 S2 in the
above example). The copy path creating function on an older model
may not have a function to add the device information for newer models
or the created path information file cannot be applied to newer models.
•
Copy paths cannot be created when the same ETERNUS DX Disk
storage system is set for the local device and remote device.
•
If the ETERNUS DX Disk storage system Box ID is changed after
setting the copy path, REC will no longer run. Create copy paths again
with the new Box ID, and then apply the new copy path information to all
the related ETERNUS DX Disk storage systems again.
•
FC-RA and iSCSI-RA cannot coexist in the same ETERNUS DX Disk
storage system.
•
Up to 16 remote devices can be connected from one ETERNUS DX
Disk storage system.
•
Up to 8 copy paths can be created between a pair of ETERNUS DX Disk
storage systems.
•
Up to 32 destination ports (FC-RA) can be connected from one port.
•
Up to 16 destination ports (iSCSI-RA) can be connected from one port.
•
Modifying copy path information in use may stop or otherwise affect
operations. Confirm that REC is not in use before modifying the
information. To check whether REC is in use, refer to the copy session
list of remote copy.
