Disk Administration

The Solaris 9 operating system requires that disk drives support a logical structure in order to access and use the storage space on the disk. The logical structure consists of a small disk label, also called a volume table of contents (VTOC), with the remainder of the disk being divided into slices or partitions. Once a partition is defined, a file system can be created within the partition. The physical and logical device name associated with a file system is actually the name of the partition in which it resides.

The Disk Label, or VTOC

The disk label, or VTOC, contains the volume name and various geometry data about the disk, such as sectors per track, tracks per cylinder, available cylinders, and so on. In addition, the disk label contains the partition table.
