side.

REC Settings
REC Line No.
Select the REC line number of the target port.
The REC line number is used to switch the communication path when a line fails. The REC line
number is used to recognize failed lines. Set different REC line numbers for each physical
communication path. When lines are in normal status, an REC can be performed regardless of the
REC line number (specifying the same REC line numbers is allowed) in the same way as
conventional REC operations. Note that no priority applies to REC line numbers.
REC Transfer Mode
Select which REC transfer mode is enabled or disabled for the target port.
When "Enable" is selected, an REC is performed in the selected transfer mode for the target port.
When "Disable" is selected, an REC is not performed in the selected transfer mode for the target
port.
When a line fails, the communication path is switched according to the REC line number of the
copy source storage system. For normal operation, set the same REC line number for the copy
source and the copy destination storage systems to recover data.
If the port mode has been changed from "RA" to "CA", the REC line number returns to the
default setting ("0"). When the port mode has changed from "RA" to "CA/RA", the current REC
line number setting is retained. Refer to "9.2.3.11 Modify Port Mode" (page 571)
for details.
