node in the cluster. If this is not applicable, proceed to step 2.
2.
Navigate to the HP MPIO EVA DSM installation directory <installdir> on the current node
using Windows Explorer.
3. Double-click the registry file (depending upon the operating system you are using):
• For Windows Server 2003 (32-bit):
<installdir>\x86\hpeaadsm_pr_on.reg
