4. Right-click in the list area and select System Option from the menu. The related dialog box
displays.
5. In the Maximum Initial Copy Activities box, enter the number of volumes that you want to be
copied concurrently during an initial copy or resync operation. The number can range from
1 to 512 volumes. The default is 64 volumes.
•
This setting may impact the performance of the main system. This depends on this setting
and the amount of I/O activity. Using the default limits the impact on performance.
•
When you specify more than 64, the system starts copying in the first 64 pairs but does
not start the 65th pair until one of the pairs is synchronized, and so on.
6. In the Maximum Initial Copy Activities (CU) box, enable or disable whether to allow the number
of concurrent initial copy or resync operations at the CU level (from 1 to 15). If disabled,
Maximum Initial Copy Activities cannot be set at the CU level.
7. In the Path Blockade Watch (sec.), enter the number of seconds that the system will monitor
for path blockades. The watch time can be set from 2 to 45 seconds. The default setting is 40
seconds.
If you create a pair with the synchronous mode, and if the status of all paths becomes
"Monitoring" because of a path error, MIH may occur in the host. The time of the Path Blockade
Watch must be shortened than the setting time of MIH timer in the host.
8. In the Path Blockade SIM Watch (sec.), enter the number of seconds the system will monitor
the SIMs that are reported when paths are blocked. The SIM watch value can be set from 2
to 100 seconds. The default setting is 70 seconds. The value you enter must be larger than
the Path Blockade Watch.
If you create a pair with the synchronous mode, and if the status of all paths becomes
"Monitoring" because of a path error, MIH may occur in the host. The time of the Path Blockade
Watch must be shortened than the setting time of MIH timer in the host.
9. The Services SIM of Remote Copy setting indicates whether or not the services SIM in remote
storage system is reporting to the host.
10. You can change the value after clicking Set by right-clicking it in the Preview list and selecting
Modify. In the dialog that appears, make any corrections and click Set.
To cancel the setting, right-click it in the Preview list and select Delete.
11. When satisfied, click Apply. This completes and saves the configuration.
