10.4.2 Recovery from a failure in one HDD

Never remove an HDD when the HDD status lamp of the HDD is OFF. If you do,
the data stored in the HDD gets corrupted.
Wear cotton gloves when replacing an HDD in order to prevent problems caused
by static electricity. If you do not, the data stored on the HDD may get corrupted.
Make sure you check the correct procedure before you start the work. If you do not
follow the correct procedure, the data stored on the HDD may be lost.
As a replacement HDD, do not use an HDD previously used in the A model or the
D model. If you do, this equipment may not operate properly or the data on the
HDDs may be lost because of configuration information mismatches or other
reasons.
Mount an HDD securely. Loose contacts and missing screws may result in a
failure.
Do not subject an HDD you are mounting and the already mounted HDDs to
shock while replacing an HDD. Otherwise, failure of the equipment may result.
Until the rebuild is complete, avoid shutting off the power for this equipment or
attaching and detaching HDDs. Otherwise, the data on the HDDs may be lost or a
failure may result.
To recover from a single-system HDD failure, perform the procedure below.
