This error occurs when the LUNs presented to the Backup Proxy for DirectSAN access are read-only.
To confirm that these LUNs are presented in Read-only access, please refer to your SAN configuration interface. If the disk is presented as Read-only, you must either connect the volume with write access or use a different transport mode (i.e., Virtual Appliance or Network).
