What version of OCI are you running? 7.0.2, or Service Pack 2 for OCI 7.0.1 has HUS724020ALA64SM,HGST,HUS724020ALA64SM,7200,2000,SATA,8.0,181.0,750.0, defined. If your OCI server cannot have internet access, installing OCI maintenance releases or the latest data source service pack is a way to consume new disk definitions as well as other fixes. I am worried about your other definition - not sure FSAS is a supported type. OCI 7.0.2 has this definition: X477_HMKPX04TA07,SEAGATE,X477_HMKPX04TA07,7200,4000,SAS,5.0,160.0,300.0,
