10.4.2 Recovery from a failure in one Drive
• Never remove a drive when the HDD／SSD status lamp of the drive is OFF. If you
do, the data stored in the drive gets corrupted.
• Wear cotton gloves when replacing a drive in order to prevent problems caused
by static electricity. If you do not, the data stored on the drive 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 drive may be lost.
• Do not use a used drive as a replacement drive, regardless of the model. Failure
to heed this instruction might result in the equipment not operating normally or the
data in the drive being lost due to inconsistent configuration information.
• Mount a drive securely. Loose contacts and missing screws may result in a
failure.
• Do not subject a drive you are mounting and the already mounted drives to
shock while replacing a drive. Otherwise, failure of the equipment may result.
• Until the rebuild is complete, avoid shutting off the power for this equipment or
attaching and detaching drives. Otherwise, the data on the drives may be lost or a
failure may result.
To recover from a single-system drive failure, perform the procedure below.
For recovery from the backup drive, see "10.5.2 Recovery Using a Backup Drive".
(1) Rebuilding while the OS is active
< NOTE >
・In this equipment, you can change the load of writing to the drive on the system during
rebuilding.
Change the settings in consideration of the impact on the system operation during rebuilding.
The factory default setting is "HIGH", which performs rebuild processing with a high load. The
lower the load of writing, the longer the rebuild processing takes. The following table shows
guidelines for rebuilding time.
