DescriptionThe driver beneath this one has failed in some way for \Device\Rdac\database\B\P4P0I0\0.
Event InformationThe following information from a newsgroup post may help you to understand this problem in a better:
1. I had the same problem when I had installed RDAC only with one Emulex Light Pulse PCI Fibre Channel HBA in the machine. After installing the second adapter to the machine I no longer had error 18 in the event log.
As far as I know RDAC is only needed for fail over (without you can see the hard disk two times). So if you not have two adapters remove the rdac software.

2. This is a failure of the IBM-RDAC-Driver, the fail over-driver for SAN-Disk´s (most probably for the IBM-FastT-Series).
