■ 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.

Examples are shown below.

mode or CA/RA auto mode in the target storage system. The X in a label name is the
controller module number and the Y is the host interface port number on the controller.
Note the following points (in this case, all of the host interface ports on CM#0 are defined):
• RA mode or CA/RA auto mode can be switched by using the "set host-port-mode"
command.
• Host interface port WWNs or iSCSI name may be confirmed using the "show fru-ce"
command.
• The limitation for the number of characters for each iSCSI parameter is as follows:
- iSCSI name: At least 4 and a maximum of 223.
- RA port CHAP authentication username: At least 1 and a maximum of 63.
- RA port CHAP authentication password: At least 12 and a maximum of 32.
- When CHAP authentication is disabled, CHAP authentication username and password
should be omitted.
- Alias: At least 0 and a maximum of 31, which must be enclosed with double
quotations.
For example:
cm0-ca0-port0 40000000abc80e38
cm0-ca0-port1 40000000abc80e3a
cm0-ca3-port2 40000000abc80e3c
cm0-ca3-port3 40000000abc80e3e
