Setting the cycle time
Cycle time is the time between updates to the remote copy when the pair
is in Paired status. The default is 300 seconds. You can set cycle time
between 30 to 3600 seconds.
Copying may take a longer than the cycle time, depending on the amount
of the differential data or low bandwidth.
To set the cycle time
1. From the command prompt, register the array to which you want to set
the cycle time, and then connect to the array.
2. Execute the autruecopyopt command to confirm the existing cycle
time. For example:
•
% autruecopyopt
Cycle Time[sec.]
Cycle OVER report
%
3. Execute the autruecopyopt command to set the cycle time. For
example:
•
% autruecopyopt
Are you sure you want to set the TrueCopy options? (y/n [n]): y
The TrueCopy options have been set successfully.

Setting mapping information
The following is the procedure for mapping information. For iSCSI, use the
autargetmap command in place of auhgmap.
1. From the command prompt, register the array to which you want to set
the mapping information, and then connect to the array.
2. Execute the auhgmap command to set the mapping information. The
following example defines LU 0 in the array to be recognized as 6 by the
host. The port is connected via host group 0 of port 0A on controller 0.
•
% auhgmap -unit array-name -add 0 A 0 6 0
Are you sure you want to add the mapping information? (y/n [n]): y
The mapping information has been set successfully.
%
3. Execute the auhgmap command to verify that the mapping information
has been set. For example:
•
% auhgmap -unit array-name -refer
Mapping mode = ON
Port
0A
