Changing the Consistency Group Options
The CT Group Option dialog box (see Figure 40 (page 102) ) allows you to change the group
options for the existing consistency groups. To display the CT Croup Option dialog box, select the
LDKC where the desired consistency group belongs, or select Used from the tree in the Asynchronous
Operation tab, select the consistency group from the list, right-click, and then click CT Group
Operation and CT Group Option.
To change the group options, you must split all the pairs in the group first.
Figure 40 CT Group Option Dialog Box
MCU-RCU Path: Allows you to select the port type for the remote copy connections. You can only
change the port type when the group does not contain any pairs.
Offloading Timer (sec.): Allows you to specify the amount of time for monitoring to transfer data
to a sidefile between 0 and 255 seconds in 1 second increments. The default setting is 90 seconds.
Enable Inflow Control: Allows you to enable the inflow control. To enable the inflow control, click
the check box. By default, the check box is selected.
Before changing this option, you should release or suspend the pairs in the selected consistency
group.
Time Out (Copy Pending) (min.): Allows you to select the maximum delay allowed for XP Continuous
Access Asynchronous copy (none or from 1 to 15 minutes, none = no timeout for the copy pending).
The default setting is 5 minutes. If the delay between the XP Continuous Access P-VOL update and
the corresponding S-VOL update reaches the specified time, the RCU will suspend all S-VOLs in
the group. A timeout occurs when the RCU was not able to settle a recordset within the specified
time, or when the RCU has not had any communications from one of the MCUs in the group within
the specified time.
You must make sure that this value is smaller than the value of the I/O timeout for the host system.
Time Out (RCU ready) (min.): Allows you to select the maximum delay allowed for re-establishing
MCU-RCU communications following an MCU power-off (none or from 1 to 10 minutes, none =
no timeout for RCU ready). The default setting is 5 minutes. If the MCU is not able to re-establish
communications with the RCU within the specified time, the MCU suspends all P-VOLs in the group.
