You may get the following error while trying to perform the resize volume operation:

Failed to extend file system on the volume.

You may get the above error when trying to resize the volumes that are part of an RVG, if the RVG has data access disabled. Check the state of the RVG in the RVG view or by running vxprint -l <rvgName> command. The command output displays the RVG status as disabled and detached. In this case, the volume is resized, but the file system is not resized as the RVG does not allow any writes to the volume. The resize operation is completed, however, if you run chkdsk command on the volume, you get the old volume size.

Enable data access to the RVG and then resize the volume.
