– 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.

Windows Server 2003 VDS support
With Windows Server 2003 Microsoft introduced the
Virtual Disk Service (VDS).
It unifies
storage management and provides a single interface for managing block storage
virtualization. This interface is vendor and technology neutral, and is independent of the layer
where virtualization is done, operating system software, RAID storage hardware, or other
storage virtualization engines.
virtualization. This interface is vendor and technology neutral, and is independent of the layer
where virtualization is done, operating system software, RAID storage hardware, or other
storage virtualization engines.
VDS is a set of APIs which uses two sets of providers to manage storage devices. The built-in
VDS software providers
enable you to manage disks and volumes at the operating system
level.
VDS hardware providers
supplied by the hardware vendor enable you to manage
hardware RAID arrays. Windows Server 2003 components that work with VDS include the
Disk Management MMC snap-in, the
Disk Management MMC snap-in, the
DiskPart
command-line tool, and the
DiskRAID
command-line tool, which is available in the Windows Server 2003 Deployment Kit.
