If FlexClone volumes are not available because the prerequisites for their use have not been met, SnapDrive uses a read/write connection to a LUN in a Snapshot copy that is actually a connection to a special type of LUN.
Read/write connection to LUNs in a Snapshot copy have the following properties:
- It is backed by a LUN in a Snapshot copy.
- It resides in the active file system and always has an .rws extension.
- When the host reads data from this LUN, it receives data that is in the LUN that is in the Snapshot copy.
- When the host writes data to this LUN, the data is written to the LUN with the .rws extension.
- When the host reads data that has been written to the LUN with the .rws extension, that data is received from the LUN with the .rws extension.
For details, see your Data ONTAP documentation.
