Verifying your VSS configuration

If the Data ONTAP VSS Hardware Provider failed to run or did not successfully complete a Snapshot copy, complete these steps.

Steps

1. Verify that SnapDrive for Windows is installed and running and can communicate with the storage system by performing the following steps.
   1. Under SnapDrive in the left MMC pane, expand the instance of SnapDrive you want to manage, then select Disks.
   2. From the menu choices at the top of MMC, navigate to Action > Refresh.

      No error messages should be displayed.

2. Verify that the lun.inquiry.mode option is set to legacy and not standard on the storage system.

   This setting applies if you are using Data ONTAP 7.2 and you are also using Exchange or SQL Server for VSS-based backups. By default, the mode is set to legacy

   Attention: To change or set this option, you must first stop FC and iSCSI services on your storage system, which might temporarily disrupt any operations currently in progress. Use fcp stop and iscsi stop to stop the services. Use fcp start and iscsi start to restart the services after setting the mode.
   1. To verify the setting, at the storage system prompt enter the following command:

      options lun.inquiry.mode

   2. To change the setting, enter the following command:

      options lun.inquiry.mode legacy.

3. Verify that the drives for which the Data ONTAP VSS Hardware Provider failed are backed by a LUN on a storage system running Data ONTAP.

   To do this, open MMC and verify that the drives appear under the Disks icon under SnapDrive.

4. Verify that the account used by the Data ONTAP VSS Hardware Provider is the same as the account used by SnapDrive by performing the following steps.
   1. In the left MMC pane, select Services and Applications > Services.
   2. Double-click the SnapDrive service in the main pane and select the Log On tab.
   3. Note the account listed in the This Account field, then click OK to close the SnapDrive Properties window.
   4. Double-click the Data ONTAP VSS Hardware Provider service in the main pane and click the Log On tab.
   5. Verify that the This Account field is selected and that it contains the same account as the SnapDrive service.
