■ Inter storage system REC path information definitions
In order to use REC, a file that specifies the inter-storage-system copy paths must be created. This contains
REC path information indicating the whole paths (copy source, copy destination, and the path between them)
that are to be used for REC.
The following examples describe the various inter-storage-system REC path information parameters.
storage-link X,Y
path-type {direct | switched}
line-speed {1-65535}
X
port-link cm
Defines the numbers of the two storage systems (the copy source and the copy destination)
that are to be linked. The numbers are those used in the storage system definitions. The
following example shows numbers from the storage system definitions being used.
storage-link 5,6
Defines the type of path connection of the connected device. If the device is connected
directly, the descriptor is "direct". If the device is connected remotely, the descriptor is
"switched". The following example is specified when using a direct connection type:
path-type direct
The following example is specified when using a remote connection type:
path-type switched
Defines an effective line speed for the path between the linked storage systems. This is the
WAN bandwidth that is actually available and used for the REC. The possible range is from 1
to 65535 and the units are megabits per second (= Mbit/s). This definition is only specified
for switched type paths. The following example specifies 100 Mbit/s as the effective line
speed:
line-speed 100
Y Z W V U
-ca -port ,cm -ca -port
Respectively defines the target host interface ports in the local and remote storage systems
in the same order as used in the "storage-link" field. In the following example, for the
"storage-link 5,6" used in the above storage system definition example, cm0-ca0-port1
belongs to storage system #5 and cm1-ca2-port3 belongs to storage system #6. In the
"cmX-portY-portZ,cmW-portV-portU" format, X and W indicate the controller module
number, Y and V indicate the host adapter on the specified controller module (0 is specified
for the ETERNUS DX200 S3 and the ETERNUS DX200F), and Z and U indicate the host
interface port number of the specified host adapter.
port-link cm0-ca0-port1,cm1-ca2-port3
Note that space characters may not be inserted before and after the commas (,). The
following example has a space character after the comma (,) (a syntax error):
port-link cm0-ca0-port1, cm1-ca2-port3
