If you do not use Hot Fix and mirroring, the entire physical partition is the
logical partition.
Figure 4 Logical and Physical Partitions on a Server Disk
The logical partition contains four redundant copies of the volume definition
table (VDT). Each table contains a list of all volume segments in that partition.
A segment is the amount of space you obtain from a storage device. Four
copies are maintained for fault tolerance. If a disk error occurs and one table
is corrupted, the file system can detect and correct the error.
The rest of the logical partition can contain any number of volume segments.
Device and Partition Numbering
All storage devices, disk partitions, and logical partitions are identified by
object numbers assigned by the NetWare operating system Media Manager.
In addition, the Media Manager assigns device names to physical devices and
adapters called object numbers.
These object numbers and device names are consistent across all NetWare
utilities and console commands so that you can easily identify the objects and
devices.
