The
HDvM - SN
computer stops, or
global-active device does not operate properly.
|
- Verify that there are no problems with the
HDvM - SN
computer, with the Ethernet connection, or with the software products, and then restart the
HDvM - SN
computer. Restarting the
HDvM - SN
computer does not affect the
GAD operations that are currently running.
- Confirm that all
GAD requirements and restrictions (such as LU types) are met.
- Confirm that the storage systems of the primary site and secondary site are powered on and that their functions are fully enabled.
- Confirm that all values and parameters (such as serial number and ID of the remote storage system, path parameter, IDs of the primary volume and secondary volume) were entered correctly.

The LED on the storage system's control panel that indicates that the channel of the initiator is available is off or blinking.
|
Contact
the
Hitachi Solution Support Center.
|
|
GAD error messages are displayed on the
HDvM - SN
computer.
|
Correct the error, and then re-execute the
GAD operation.
|
|
The status of a path to the remote storage system is abnormal.
|
Check the status of the paths in the Remote Connections window, and make the required corrections.
|
|
A timeout error occurred while creating a pair or resynchronizing a pair.
|
- If a timeout occurred due to a hardware error, a SIM is generated. Contact
the
Hitachi Solution Support Center, and after solving the problem, re-execute the
GAD operation.
- Large workload: If a SIM is not generated, wait for 5 to 6 minutes, and then check the status of the pair you want to create or resynchronize. If the pair status correctly changed, the failed operation completed after the timeout error message was displayed. If the pair status did not change as anticipated, the
GAD operation cannot complete due to the large workload. In this case, re-execute the
GAD operation when the workload of the storage system is smaller.
- If a communication error between
HDvM - SN
or management client
and the SVP occurred, see
Hitachi Device Manager - Storage Navigator User Guide.

|
A
GAD volume has pinned tracks.
|
Recover the pinned track volume.
|
|
The monitoring switch is enabled, but the monitoring data is not updated.
|
- The monitoring data might not be updated because the time setting of SVP was changed. Disable the monitoring switch, and then enable it again. For details about the monitoring switch, see the
Provisioning Guide for the storage system.
- Verify that the settings for the target being monitored are correct.
