with either disk mirroring or, with a second disk controller, disk
duplexing.
− Volume set
A volume set is the combination of two or more various-sized areas of
free space on one or more physical disks into one logical drive, treated
like a single partition. This mechanism allows you to use the total
available disk space more effectively.
Volume sets can be extended dynamically by adding more unused space
to the set. However, the system must be rebooted before the additional
disk space is accessible.
Other OS
Be aware that other OS systems such as DOS or OS/2 do not recognize
partitions within a disk set so they will not be accessible to them.

Fault Tolerance Administration
Through the Fault Tolerance Administration you can establish and break disk
mirroring, create stripe sets with parity (RAID 5) and regenerate them after a
fault occurrence.
For more information about disk managing with Windows NT, please refer to the
Windows NT Administration Guide or to the online help.
Figure 80. Windows NT Disk Administrator
The following is an explanation of Figure 80:
•
Part C: is mirrored on Disk 1 and Disk 2.
•
Part E: is a disk stripe set with parity.
•
Part F: is a primary partition.
•
Part G: is a extended partition.
•
Part H: is a volume set using the remaining disk space.
Drive letter D: is used by the CD ROM drive and could not be used for a
partition.
