HDvM - SN hangs, or SI pair tasks are not properly performed.

• Make sure all SI requirements and restrictions are met.
• Make sure the storage system is powered on and fully functional.
• Make sure the input values and parameters on the SI windows are correct (such as P-VOL and S-VOL IDs).

The volume pairs are not displaying correctly.

Select the correct volumes.

An SI error message is displayed in HDvM - SN during a task.

In HDvM - SN, check if there is an error message for the failed task.

Note: You can use HDvM - SN to set up email notifications of errors that occur during pair tasks.

For more information about managing your tasks and setting up email notifications, see the Hitachi Device Manager - Storage Navigator User Guide.

For a list of error codes and corrective actions, see Storage Navigator Messages.

Pair status is incorrect (or unexpected).

The pair might have been suspended or deleted from the UNIX/PC server host using a RAID Manager command. If this did not happen, then the storage system detected an error condition during SI tasks. Check the HDvM - SN error log. If necessary, contact the Hitachi Solution Support Center.
