Enabling or disabling data access to the RVG data volumes


Enabling or disabling data access to the RVG data volumes
Prev	Administering the RVG	Next

The user or the application can write data to the data volumes only if the data access is enabled for the volumes. This operation prepares the volumes to receive the writes from the application. The disable data access operation prevents the user or application from writing any data to the data volumes.

The enable data access operation first tries to lock all the volumes under the RVG and fails if it is unable to lock the volume because of the following reasons:

Some application or file handles are still open on the volume.

The disable data access operation requires that no application should use those volumes.
The volume drive letter is currently being accessed through the explorer.
The drive letter is active in the command prompt.

This option is available from the right-click menu of the Primary and Secondary RVG, and is a toggle option. If the RVG already has the data access enabled, then, the menu displays the Disable Data Access option. Otherwise, the menu displays the Enable Data Access option.

Note:

If Volume Replicator is configured in a VCS or Microsoft Cluster and the cluster resource for this RVG exists, then Volume Replicator fails the Disable Data Access operation as this can cause the resource to fail.

Use the vxrvg dismount command to verify whether Disable Data Access operation succeeds.

Note:

If the data access to the Primary RVG is disabled, the Primary data volumes with NTFS or ReFS file systems may be displayed with a status as MISSING. To view these volumes enable data access to the Primary RVG and use the Actions > Rescan option from the VEA.

To enable data access

Select the Primary RVG and right-click. Select the Enable Data access option from the menu that appears.
The Enable Data Access dialog box appears.
Click Yes to enable data access to the Primary RVG. Click No to cancel the operation.
