Recovery From Failure In Both Hdds; Recovery A Normal Hdd That Has Been Set To Offline By Mistake - Hitachi HF-W2000 Instruction Manual

10.4.5 Recovery from Failure in Both HDDs

After you replace both HDDs, set up the equipment again (see "10.2.2 Newly setting up
RAID1") and recover the data from the backup file.
Alternatively, recover the equipment using a backup HDD. (See "10.5.2 Recovery Using a
Backup HDD".)

10.4.6 Recovery a normal HDD that has been set to offline by mistake

On this equipment, the RAID board keeps track of all HDDs that have been set to offline
(hereinafter referred to as an "offline HDD") for any reason. Therefore, an offline HDD cannot be
used in the equipment that sets the HDD to offline.
But as an exception, if a normal HDD is set to offline by mistake or if an HDD is set to offline
by the RAS software for evaluation of the equipment, the following action can restore the offline
HDD, and allow it to be used as a new HDD again.
● If you apply the recovery method for an offline HDD to an HDD that was set to
offline by something other than the RAS software, the HDD may not be
recovered, or even if it is recovered, the HDD may not work properly.
● Use the recovery method for an offline HDD only for the purpose of evaluating
the equipment. If you apply the recovery method for an offline HDD to
equipment actually used in the field, for example, a system in normal
operation, malfunctions may result, including data loss.
● If an HDD is automatically set to offline by the equipment, the HDD may
possibly be out of order. Do not apply the recovery method for an offline HDD
to such an HDD.
● An HDD recovered by the recovery method for an offline HDD must not be
used for equipment actually used in the field. If used, malfunctions may result,
including data loss.
1. Shut down the OS and unplug the power cord of this equipment from the outlet. Then, wait
for at least one minute and remove the normal HDD. Record the drive bay number of the
removed HDD.
2. Mount only the offline HDD.
3. Initialize the offline HDD using the Software RAID Utility. Refer to"10.6.2 Starting and
exiting the Software RAID Utility" and "10.6.7 Drive initialization function".
Wait for about one minute, and then mount the offline HDD and the normal HDD removed at
4.
step 1 back into the original HDD drive bay.
(Check the recorded drive bay number and make sure that the mount location is correct.)
Now, the offline HDD can be used as a new HDD again.
