Replacing hot-plug components

8.1 Replacing hot-plug components
This chapter explains how to handle the hot-plug components and how to make
hardware changes to your server in general (e.g. adding or replacing hot-plug
hard disk modules).
The hot-plug option increases the system availability and ensures a high degree
of data security and reliability.
8.1.1

Hot-plug hard disk drives

The hard disk drives that can be ordered for the PRIMERGY BX620 S6 come
mounted in a module frame that allows you to replace defective drives and add
new ones while the system is running. The hard disk drive and the module frame
are together referred to as the hard disk module.
V
CAUTION!
A hard disk should only be removed from the hard disk module by a
service technician.
All hard disk modules (drives) must be clearly labeled so that you can
replace them in their original bays should you remove them. If you mix
up the hard disks you might lose existing data.
Hot plugging is only possible in conjunction with a corresponding
RAID configuration.
Generally, the two disks are mirrored in a RAID-1 configuration to
save the data fault-tolerantly.
For more information on RAID configurations or RAID levels, see the
RAID controller documentation.
V
CAUTION!
A mixed configuration of SAS and SATA hard disk modules is not
possible.
