MCU-RCU Path: Indicates the path type (fibre) for the remote copy connections. Currently, you
cannot change the path type.
Offloading Timer (sec.): Allows you to specify the amount of time for monitoring the transfer of 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 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 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.
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 =
0 minutes). The default setting is 5 minutes. If the MCU is not able to re-establish communication
with the RCU within the specified time, the MCU suspends all P-VOLs in the group.
To add one or more consistency groups to the connected MCU:
1.
Make sure that the async options are configured as desired.
2.
Select the LDKC where the desired consistency group belongs or select Not Used from the tree
in the Asynchronous Operation tab to display the unused consistency groups in the list.
3.
Select the (unused) consistency group(s) that you want to add. The XP24000/XP20000 disk
array supports up to 128 consistency groups (00-7F) per LDKC and allows you to use up to
128 consistency groups per entire storage system. The XP12000/XP10000 disk array supports
up to 128 consistency groups (00-7F).
4.
Right-click the selected group(s), click CT Group Operation, and then click Add CT Group to
open the Add CT Group dialog box (see
).
5.
On the Add CT Group dialog box, select the desired path type and group options (copy
pending timeout, RCU ready timeout).
You will not be able to modify the path type of the group after you assign a pair to the group.
6.
Click Set to close the Add CT Group dialog box. (Click Cancel to cancel the add group
operations.) The preview list displays the requested add group operation(s).
