We are using App Manager to monitor our Microsof 2012 Cluster.

Don`t know why but every time I am getting error

Health of MS Cluster is critical. 
Root Cause : 

1. Health of FMPMSSQL01-CL is critical. 
   Root Cause : 
   1. Available Storage  State Offline contains Failed,Offline,StateUnknown (threshold).
   
2. Health of FMPMSCL1 is critical. 

Available Storage is online and there is no trouble.

To get rid of this error I have disable alarms on Available storage but few weeks later I am getting the same error. I also disabled and deleted Available Storage from montoring but it comes back...with error - don`t know why 

What to do to get rid of this error. I do not want to monitor this resource but deleting it is not solving the problem (resource is coming back )
