Hot-swap Hard Disk Drive
Up to four Ultra 3-Wide U320-SCSI hard disk drives can be installed into the
PRIMERGY TX150 server.
The 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 under “Hard disk drive control indicator” on page 58).
The hot-swap procedure increases the availability of the system operation and
guarantees a high degree of data integrity and protection against failure.
8.2.1
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).
●
Never expose a HDD module to a temperature shock. Avoid the formation
of condensation inside and on the outside of the hard disk drives.
