Detaching/Attaching Hard Disk Drive (Hdd) - Hitachi HF-W2000 35 User Manual

5. INSPECTION AND MAINTENANCE

5.4.3 Detaching/attaching hard disk drive (HDD)

 Be sure to shut down the OS, disconnect the power cord plug from the outlet,
and wait at least one minute before you detach or attach an HDD on D Model
(if you intend replacement while the Equipment power is off) or A Model.
Failure to do so may cause an electric shock or a machine failure.
 To avoid finger injury while detaching/attaching an HDD, pay attention not to
get your fingers caught by any protrusion.
 When detaching/attaching an HDD, check out the target drive bay number. If
you attach a new HDD to a wrong drive bay, the Equipment may not start or
the data may be lost because of inconsistency of the configuration information.
 Pay attention not to apply shock to the replacing HDD and the replaced HDD
during work, whether installed or not installed on the Equipment. When not
installed, place each HDD on a shock-absorbing material such as antistatic
cushion, even temporarily. Direct placement on a hard surface such as
desktop may cause damage, data corruption, or shortening of service life due
to shock.
 Insert the HDD firmly and precisely. A loose contact or a missing screw will
cause a failure.
 While the HDD is powered, never attempt to unscrew and hot-plug the HDD.
Otherwise, a machine failure or HDD failure may result.
 The HDD detachment/attachment must be limited to the least, e.g.,
replacement in the event of a failure. Frequent detachment/attachment may
cause damage to the Equipment.
 On D Model, also observe the following:
 Do not altogether replace the two HDDs in RAID1 configuration.
 Since each D Model has its own RAID1 configuration information (e.g.,
serial number), you cannot swap HDDs even between D Models. If you
dare, the stored data in the newly installed HDD will be erased with
automatic RAID1 rebuilding process due to inconsistency of the RAID1
configuration information. If you own multiple D Models, manage use and
inventory of HDDs so that they are not inadvertently mixed.
 Never remove the HDD if the corresponding HDD status lamp is off.
Otherwise, the stored data will be destroyed.
 Do not remove or insert an HDD when the "Hardware status" window cannot
be checked, for example, immediately after the OS starts. Otherwise, a
machine failure or HDD failure may result.When you remove or insert an
HDD while the power is on, make sure you put the HDD into the OFFLINE
state in the "Hardware status" window before removing or inserting the HDD.
