Replacing the hard disk

The BCM1000 includes either one or two factory-installed hard disks. You also can install a second hard disk to a single-disk base unit. (Not available to BCM1000 hardware manufactured for the BCM 2.0 release).

This chapter explains how to change a hard disk, and how to upgrade a single-disk system to a mirrored system by adding a RAID board and a second hard disk.

Figure 76 provides an overview of the hard disk replacement process.
