The pack must be offline.The plex count for the volume must begreater than zero.The member count for the volumemust be greater than zero.The plex indexes must start at zeroand increase monotonically.The member indexes must start atzero and increase monotonically.The stripe size in bytes must be apower of 2 for striped and RAID-5volume types and must be zero for allother volume types.The number of disks specified is notvalid for this operation.An invalid number of extents wasspecified for at least one disk.The source and target packs must bedistinct.The specified number of disks is toolarge. VDS imposes a 32-disk limit onspanned, striped, and striped withparity (RAID-5) volumes.The driver's notification information iscorrupt.GUID_NULL is not a valid plex GUID.The specified disks do not belong tothe same pack.100 / 360[MS-VDS] — v20110610Virtual Disk Service (VDS) Protocol SpecificationCopyright © 2011 Microsoft Corporation.Release: Friday, June 10, 2011
