3.1 Devices That Are Hot-Pluggable or
Hot-Swappable
3.1.1 Hot-Pluggable Devices
Hot-pluggable devices can be removed and installed while the server is running, but
you must perform administrative tasks before or after installing the hardware (for
example, mounting a drive).
In the Sun Fire X4240, only drives are hot-pluggable. To hot-plug a drive you must
take the drive offline (to prevent any applications from accessing it, and to remove
the logical software links to it) before you can safely remove it. See
Section 3.2,
“Servicing Drives” on page 3-2 .
