SI actions and display troubleshooting

The following table provides symptoms and suggested corrective actions for troubleshooting SI pairs.

Symptom

Corrective action

SN hangs, or SI pair task are not properly performed.

  • Make sure all SI requirements and restrictions are met.

  • Make sure the storage system is powered on and fully functional.

  • Check all input values and parameters to make sure that you entered the correct information on the SI windows (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 SN during a task.

Check the error message for the failed task in SN.

Note: You can use SN to set up email notifications of errors that occur during pair user 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 may 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 SN error log. If necessary, call the HSSC.
