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.
