About Hot-Pluggable Components

In a Sun Fire V440 server, the SCSI hard disk drives and power supplies are hot-
pluggable components. No other component of the system is hot-pluggable. Hot-
pluggable components are those that you can install or remove while the system is
running, without affecting the rest of the system's capabilities. However, you must
prepare the operating system prior to the hot-plug operation by performing certain
system administration tasks.
For information about performing a hot-plug operation on a mirrored disk, see:
Sun Fire V440 Server Administration Guide
