Hi, We have IBM 3950M2 servers with local disks (SAS) and a number of SAN disks (HP HBA). When we use MDT's 2008 WinPE 2.0 image to boot the server and start the Windows 2003 installation we see about 38 disks in diskpart, however the local disks (where we want to install the OS) are last in line (disk 36, 37 and 38). Since we do not have the same number of SAN disks in every server we have a problem formatting the disks with the standard format sequence in MDT 2008. The local disks should be numbered disk 0, 1 and 2 in stead of 36, 37 and 38 so we can use the format sequence always in disk 0. How does WinPE 2.0 determine the disk order and how can we change the order so that the local SAS disks are always disk 0, 1 and 2 (in this case we have three disks in RAID configured) Thanks you if you review and even answer this question.
