Hot Plug
The system's disk bays are designed to permit disk drive removal and insertion
while the system is powered on. Hot-plug technology significantly increases the
system's serviceability and availability, by providing the ability to:
Add additional hardware dynamically to enable the system to handle an
increasingly larger work load, perform load balancing, and improve performance
of a running system.
Remove/replace faulty hardware with minimal system service disruption.
For more information about hot-pluggable disk drives, see "About Internal Disk
Drives" on page 54.
