Windows Server 2003 Vds Support - IBM TotalStorage DS6000 Series Redbooks

– If you reboot a system with adapters while the primary path is in a failed state, you
must manually disable the BIOS on the first adapter and manually enable the BIOS on
the second adapter. You cannot enable the BIOS for both adapters at the same time. If
the BIOS for both adapters is enabled at the same time and there is a path failure on
the primary adapter, the system will stop with an INACCESSIBLE_BOOT_DEVICE
error upon reboot.
