When adding logs to dissociated volumes, the following error message is displayed:

The requested operation is not valid.

If you try to add a log to a volume that has been dissociated from the RDS, you may get the above error. The volume may already have a DCM log associated with it.

The DCM log may have got added when you had added this volume to the RDS with the Add DCM log to all selected volumes option selected. Now that the volume is dissociated from the RDS, if you try to add the DRL log to it you may get the error message given above, as DRL and DCM logs cannot exist together.

To find out the type of the log associated with the volume that you want to add; click on the volume name in the tree view. The right panel of the VEA displays the volume properties. Click the logs tab to see the type of log associated with the volume.

If you need to add the dissociated volume back to the RDS later, do not add DRL log to the volume. Otherwise, you can remove the DCM logs and add the DRL logs by using the options that you get when you select the volume and right-click on it.
