7 FC Hard Disk Drives
Up to fourteen one inch hard disk drives can be installed into the
PRIMERGY S60 storage subsystem. The FC hard disk drives can be controlled
via up to two FC ports. The two FC ports are in each case over two outward lead
Nodes in one loop. This means that each port is in one FC Loop (all ports A
from the FC hard disk drives are in the same loop as the channel 0 from (both)
FFx-RAID controller(s) and all ports B from the FC hard disk drives are in the
same loop as the channel 1 from (both) FFx-RAID controller(s)).
The FC hard disk drives are built on a carrier which allows defective drives to
be replaced (hot swap) or new drives to be added during operation. The hard
disk drive and the carrier constitute the hard disk drive module (HDD module).
The hot-swap function can only be performed together with a corresponding
RAID configuration. Further information about the RAID configuration or RAID
level can be found in the RAID controller documentation.
A hard disk drive may only be replaced if it is inactive (see description of the
LEDs in the table “Meaning of the HDD Control LEDs Indication” on page 19) or
if it has been marked as defective in the management tool.
The hot swap procedure increases the availability of the system operation and
guarantees a high degree of data integrity and protection against failure.
7.1 Handling Hard Disk Drives/HDD Modules
Hard disk drives incorporated in the HDD modules are highly sensitive electro-
magnetic devices and must be handled with great care. It is extremely likely that
an incorrect handling will lead to a partially and/or total failure of the hard disk
drives.
These failures will result in data errors and to loss of data or to total destruction
of the hard disk drive.
Please observe following rules, which will help to avoid the occurrence of this
type of problems:
● Store and transport HDD modules only within the limits stipulated in the
specification.
● When transporting HDD modules (even over short distances), always use
the original packaging (ESD labeling).
