Simplify Administration of Large Configurations The DiskSuite Tool graphical interface makes working with many disks quick and easy. It supports drag-and-drop operations and provides physical and logical views of the system.

Solstice DiskSuite 4.1 Reference, Chapter 4, "DiskSuite Tool"

Graphically Administer Slices/File Systems DiskSuite is integrated with the Solstice Storage Manager graphical user interface. Use it to administer your disks and file systems, performing such tasks as partitioning disks and constructing UFS file systems.

Appendix A, "Using Storage Manager"
