no, i got this test san box for testing oracle applications before deploying rman backup.

ok.

Port 0 = FCS0 of Dual Port Fibre Card connected to Controller A
Port 1 = FCS1 of Dual Port Fibre Card connected to Controller B

DS Storage Client Software, in mappings, I can see only one Default Group to which I assigned one disk.

NAME

       hbaapi - Fibre Channel Storage Network Industry Association Host Bus Adapter Application Programming Interface (FC SNIA HBA API)

DESCRIPTION

       The  Common  HBA  API  provides a consistent HBA standard interface for accessing information in a Fibre Channel Storage Area Network (SAN)
       that would be implemented across vendors as a standard 'C' API supported by vendor specific library instances.

       This API library is thread-safe, but threads should not be cancelled when execution is in the API.

       The following functions are available in the API for managing a Fibre Channel HBA.  This API would be exposed to upper  level  applications
       to control SAN functionality.

       Please refer to for details on structures used.
