Oracle FS Path Manager (FSPM) uses the Windows Multipath I/O (MPIO) feature. Unless your system already has some other MPIO-based multipathing solution installed, the installation of FSPM will install and enable MPIO. It is therefore possible that issues caused by this Microsoft multipathing feature may become apparent on your system after installing FSPM. The following table lists current entries in the Microsoft Windows Knowledge Base describing issues that may apply when Microsoft MPIO is implemented on your system.
