Recovery By Using A Backup Hdd - Hitachi HF-W2000 58 Instruction Manual

10. SOFTWARE RAID1

10.5.2 Recovery by using a backup HDD

● Wear cotton gloves when replacing an HDD to prevent problems caused by static electricity.
Not doing so might result in corruption of the data stored on the HDD.
● Verify correct procedures before starting work. Failure to follow the correct procedures might
result in data stored on an HDD being lost.
Prepare a backup HDD and a brand-new HDD, or a new HDD on which "Initialize Drives" has been performed.
Then, recover the array by performing the following procedure. For details about installing or removing an HDD,
see 6.3.6 Installing and removing an HDD or SSD.
NOTE
• The following is the procedure for the HDD installed in drive bay 1. If you are making a backup HDD from the
HDD installed in drive bay 2, interpret "drive bay 1" as "drive bay 2".
• When a brand-new HDD or a new HDD is installed, its capacity must be the same as the capacity of the backup
HDD.
1. Shutdown the OS and unplug the power cord. If HDDs are installed, remove both HDDs.
2. Install a backup HDD in drive bay 1 and install a brand-new HDD or a new HDD in drive bay 2.
3. Turn on power to the equipment. The RAID1 automatically detects a brand-new HDD or a new HDD, and
starts rebuilding the system.
When the rebuilding starts, the DRIVE2 status lamp blinks.
4. The OS starts while the rebuilding process continues. The time required for the rebuilding process depends on
what applications are executed during this period.
If you do not want to start the OS, start the rebuilding process by using the software RAID utility.
5. When the DRIVE2 status lamp turns off, the rebuilding process is complete. In the Hardware status window,
verify that the status of both HDDs is normal.
