Invalid Virtual Machines "VM1" is no longer protected in SRM

Hello,

   I was going through protected group of our SRM environment and i found the error

Invalid: Virtual machines"VM1" is no longer protected.Cannot protect virtual machines'VM1' becuase its config file "[SRM_XG_VMAX_5442_LUN_2EXD_Management]\VM1\VM1.vmx is located on a non-replicated datastore or non-protected data store.

I am new to SRM. Any help to troubleshoot this error will be appreciated. I have attached the screen shot.

Thanks
