Configuration of Shared Storage
With our Fibre Channel network topology now defined, we are ready to configure the disks. As Windows 2000 loads, our HBA driver starts the storage virtualization process, which "fools" the operating system into thinking our fibre connected storage device is actually a directly connected SCSI device. With this deception, we are now able to configure the storage using standard Windows 2000 disk management utilities. Right-click My Computer / Manage / Storage / Disk Management. The storage device appears as a new disk that requires a disk signature, or needs to be imported to the system, depending on the devices previous disposition. The Windows wizards will walk you through either step. Its important to note that in heterogeneous SANs, Disk Manager will not recognize the file systems of other operating systems. Writing a disk signature to these shared disks will ruin the data already stored on them. (See section on Zoning and LUN masking below)In order to use the new SAN disks, we had to use Disk Administrator to format the new disks (right click on unallocated disks and choose format option). This method will allow you to add Fibre Channel volumes to your server, but its important to note that you will need volume management software like PowerQuests PartitionMagic or Veritas Volume manager to increase, decrease, or merge multiple volumes. Our point-to-point SAN is now ready for use.
