A drive is an electromagnetic mechanical device that provides the physical storage media for data.

Overview and requirements

Before you replace a drive, you need to be aware of certain requirements and considerations.

Drives overview

You can replace a drive in either a 24-drive or 60-drive controller shelf or drive shelf.
24-drive shelves
The figures show how the drives are numbered in each type of shelf (the shelf's front bezel or end caps have
been removed).

60-drive shelves
Both the HB5200 controller shelf and the DE460C drive shelf consist of five drive drawers that each contain 12
drive slots. Drive drawer 1 is at the top, and drive drawer 5 is at the bottom.
For both an HB5200 controller shelf drawer and a DE460C drive shelf drawer, drives are numbered from 0 to
11 in each drive drawer within the shelf.
