8 Hot-plug Components
This chapter describes how to handle hot-plug components and/or how to
modify your server hardware (e.g. hot-plug HDD modules).
I
Upgrading or replacing fix installed components are described in the
Service Manual and may only be performed by maintenance staff.
The hot-plug procedure enhances the availability of system operation, ensuring
a high degree of data security and system stability.
8.1 Hot-plug Hard Disk Drives
Up to two hot-plug hard disk drives can be installed into the PRIMERGY RX220
server.
The hard disk drives are built on a carrier which allows defective drives to be
replaced or new drives to be added during operation. The hard disk drive and
the carrier constitute the hard disk drive module (called "HDD module" in the
following sections).
V
CAUTION!
Only a service technician may remove a hard disk drive from the HDD
module.
V
CAUTION!
The HDD modules must be marked clearly so that they can be put back
into their original place after an upgrade. If this is not taken into account,
existing data can be destroyed.
V
CAUTION!
The hot-plug function can only be performed together with a corre-
sponding RAID configuration.
Further information about RAID configurations or RAID levels can be
found in the RAID controller documentation (see
“Related Publications”
on page 75 ).
