I/O errors from unknown storage device after installing a new SAN network
Issue
-
Just installed EMC software, EMCpower, NAVICli, and NAVIHostAgent. When the system boots the system logs show repeated kernel I/O errors.

The system is connected to the SAN but no disks have been assigned yet. The only disks right now are local :
