Answer

The following messages are reported when taking a Logical Unit Number (LUN) backup:

[lun.map.unmap:info]: LUN /vol/vol1/Lun1/{9b60d92c-fe4c-476e-8d42-ed88e642b71b}.rws unmapped from initiator group viaRPC.iqn.1991-05.com.microsoft:test.netapp.com
[lun.destroy:warning]: LUN /vol/vol1/lun1/{9b60d92c-fe4c-476e-8d42-ed88e642b71b}.rws destroyed

The messages are normal when taking a LUN backup.  In order for the system to take a backup, it creates a file with the extension of .rws and makes a snapshot of it. After the snapshot is taken, it deletes the .rws file.
