Assigning/Removing Drive Letters for Windows NT
This chapter discusses assigning and de-assigning drive letters on your Windows
NT system.
Temporarily Removing Drive Letters
This section is required only when you have created NTFS partitions on your
Enterprise & Modular Storage RAID Array system before the installation of the
HszDisk class driver. If you have not created NTFS partitions, proceed
to“Software Setup Summary for a Fibre Channel Cluster” on page 245.
The inclusion of the HszDisk class driver when NTFS partitions exist on your
Enterprise & Modular Storage RAID Array system causes Windows NT to
reassign the drive letters. HszDisk inserts all NTFS partitions on your Enterprise
& Modular Storage RAID Array ahead of any local (non-shared bus) partitions.
Windows NT would, for example, reassign drive letter C from your system disk to
the first NTFS formatted storageset partition, Disk 0).
Since drive letter reassignments by the HszDisk class driver could invalidate your
drive mappings, you must temporarily remove NTFS drive letter assignments
for all partitions on the Enterprise & Modular Storage RAID Array prior to
installing the HszDisk driver. Do not remove drive letters for any drives that are
not configured on your Enterprise & Modular Storage RAID Array Fibre Channel
system.
