• To address this issue, check the Storage Array and ensure that the storage array is up and running.  Ensure it's pingable from the SRM appliances.
  Verify the IP Address: Confirm that the IP address of the storage array is correct and reachable through the command line interface

Resolution

• Open a new support ticket with Storage Vendor to investigate on, why the storage array cannot be reached by the SRA.
  
  
• Everything pertaining to SRA-attached storage for the Site Recovery Manager Appliance is under the purview of the storage provider Therefore, it is necessary to isolate at storage vendor initially.

Additional Information

Update Dell SRA Solution Enabler to the most recent version of SRA or engage SRA vendor
