Replacing a hard disk

Before you replace a hard disk, determine whether the disk is truly bad.
See Deciding on hard disk recovery or replacement on page 67
that determination.
After you replace a hard disk, synchronize the new disk with the older disks
in the system.

Deciding on hard disk recovery or replacement

A number of hard disk drive failures can occur. Some failures require disk
replacement, others only require performing a recovery process. Use the
process described in this section to help ensure that all partitions are
recovered before proceeding with any further disk recovery or replacement
procedures.
Before you consider replacing a hard disk drive, be sure you understand the
following points:
• Do not attempt to replace an HDD unless you are instructed to do so by
Hitachi Data Systems Support Center.
• Failed hard disks are hot-swappable, so a failed hard disk can be replaced
without shutting down the server. However, there are serious risks in
trying to swap a drive that is not failed.
• Do not assume that because the red LED is illuminated that a drive is
faulty. Under a RAID rebuild/recovery, the red LED would be illuminated. If
the drive is failed and needs replacing, you can remove it from the server.
• Do not replace a drive that has not actually failed. If the disk shows signs
of failure, shut down the server before replacing the drive and restarting
the server.
• There should be no reason to pull out a hard drive while it is in a known
good configuration, and doing so can potentially lead to data corruption.
• Unless you are certain the hard disk has failed, perform a disk recovery.
