    Recovery Server Option Incompatibility Compaq Recovery Server Option consists of the Standby Recovery Server and the On-Line Recovery Server. OSCRO cannot be run in conjunction with either Recovery Server Option because both require hardware connectivity to ProLiant Storage Systems through the same interfaces and, although the cables are the same type, the cabling requirements are not compatible.
