Hi,
Oneview doesn't support MSA iscsi model as per the support matrix:
https://support.hpe.com/hpsc/doc/public/display?docId=a00059959en_us
You may consider HPE IRS: It provides call to home feature using SNMP/WBEM:
http://h17007.www1.hpe.com/us/en/enterprise/servers/supportmatrix/insight_rs.aspx
You may log a support case with HPE and IRS configuration team would get in touch with you and share more details.
Note: I am not sure about the future enhancements in MSA firmware.
