Modifying data-transfer time threshold
You can modify the threshold for data transfer to complete. If the threshold value is reached, the
transfer is flagged as failing by the system.
Prerequisite information
•
This operation can be performed from the primary or secondary system.
•
The setting is made in the RIO MIH field on the DKC Options dialog box (RIO MIH--remote
I/O missing interrupt handler).
Procedure 29 To change the data-transfer threshold time
1. In the Storage System tree, click Replication > Remote Connections.
2. In the Remote Connections window, click the Connections (To) tab, then select the secondary
system with the data-transfer waiting-time to be changed.
3. From the Actions menu, click Remote Connections > Edit Remote Connection Options.
4. In the Edit Remote Connection Options window, note that Minimum Paths cannot be changed.
5. For RIO MIH Time, specify the amount of time the system waits before a data transfer operation
is flagged as failed. The range is from 10-100 seconds; 15 is the default.
6. Click Finish.
7. In the Confirm window, review the settings and enter a task name in the Task Name box.
8. Click Apply to save your settings to the system.
Deleting remote paths
You can delete remote paths from the primary or secondary systems.
Prerequisite information
•
Before deleting remote paths, make sure that the remaining number of remote paths will be
greater than the minimum number of paths setting. You can do this in the Remote Connections
window. The delete path operation will fail if the number of remaining paths is equal to or
less than the minimum number of paths.
•
The primary system administrator can delete remote paths between the initiator port of the
primary system and the RCU target port of the secondary system. The remote System
administrator can delete remote paths between the initiator port of the secondary system and
the RCU target port of the primary system.
Procedure 30 To delete a remote path
1. In the Storage System tree, click Replication > Remote Connections.
2. In the Remote Connections window, click the Connections (To) tab, then select the secondary
system with the remote path you want to delete.
3. From the Actions menu, click Remote Connections > Remove Remote Paths.
4. In the Remove Remote Paths window, in the Remote Paths box, check the Remove box or
boxes for the remote paths to be deleted.
