Identifying LUNS in Windows 2000 or NT 4.0
Voyager’s SAN is being used to host the storage requirements of several different systems, including mainframe storage requirements. This storage diversity demands specialized configuration of the disks (or logical devices) that are grouped and presented as basic disks to the Windows 2000 operating system.
Voyager found that Windows 2000 must locate a disk assigned as LUN 0 before it will scan and identify any disks with LUNs greater than 0. In order to correlate certain logical devices and LUN schemes, Voyager chose to assign a small disk or logical partition as LUN 0. This allowed Windows 2000 to always identify other non-zero LUNS.
