Hot-Pluggable Drives

The ProLiant Storage System /F supports these Compaq hot-pluggable drives:
ProLiant Storage System will accept both 1-inch and 1.6-inch standard height
drives. The drives may be of any storage capacity but must be mounted on
Compaq hot-pluggable drive trays.

Hot-Pluggability

The ProLiant Storage System supports hot-pluggable drives. Under certain
conditions these drives can be removed or installed without turning off the
power to the storage system or the server. This feature eliminates interference
with the operation of the server while replacing drives in some configurations.
In planning your configuration it is important to understand that the hot-
pluggability feature must also be supported by the operating system and
controller. See Table 2-1.
Hot-pluggable drives in fault-tolerant configurations can be used to replace
failed drives without powering down your system. The data on the failed drive
will be automatically restored on the replacement drive.
