SYMPTOMS
When you restart your server, some Digital Array controllers may randomly lose the shared drive in a cluster.



CAUSE
This behavior can occur if the /pcilock switch is enabled on one computer but not on the other.



RESOLUTION
To resolve this behavior, enable the /pcilock switch in the Boot.ini file. Then, shut down and then restart the computer.



MORE INFORMATION
The /pcilock switch prevents the hardware abstraction layer (HAL) from moving anything on the PCI bus. The I/O and memory resources are left exactly as they were set by the BIOS.
