The setup begins. You will see nothing until after a minute or two, when the server reboots.
3. When the server is back up, check \Windows\dsminstall.log for errors.
Connecting volumes with MPIO
Once the HP DSM for MPIO or Microsoft DSM is installed on the server, all iSCSI volume connections
made to an iSCSI SAN will attempt to connect with the DSM. You do not need to configure the multiple
I/O paths manually.
If you are also using the Multi-Site SAN features, you can assign servers to specific sites to avoid
high-latency connections between sites. For more information, see the HP P4000 Multi-Site HA/DR
Solution Pack User Guide.
