Replacing A Disk Drive - Hitachi AMS 2000 Series Service Manual

Replacing a disk drive

NOTE: Disk drives are replaceable only while the power is turned on. If the
LEDs do not indicate the correct status as described in the steps below, or
if there is any indication in the error log or Navigator 2 Alerts windows that
two drives in the same RAID Group have failed, please contact Hitachi Data
Systems Support for assistance. See the
for information on how to contact Support.
CAUTION! Back up any user data before replacing a disk drive in
the RAID 0 configuration. When a RAID group and logical unit are
deleted or formatted, related user data will be lost.
Complete the following steps to replace a failed disk drive. This procedure
is used when replacing a disk drive in RAID 0, 1, 5, 6, or 1+0 configuration
and the Alarm LED is ON.
1. Remove the front bezel from the base or expansion unit.
2. Verify that the Alarm LED on the failed drive is ON.
3. Important! If a spare disk is not set, or if the drive is in the RAID 0
configuration, back up the data on the failed drive. Note that this is not
done automatically.
4. Remove the failed disk drive from the unit. See
on page
5. Wait at least 20 seconds but not more than ten minutes after removing
the failed drive and then install a replacement disk drive. See
a disk drive on page
6. The Alarm LED on the replacement drive should go out about 5 minutes
after the new drive is installed.
7. As soon as the replacement disk reaches the ready state, the data from
the failed disk is automatically copied to the replacement disk and the
failure recovery is displayed in Navigator 2.
8. Launch Navigator 2 and display the Alerts window.
9. Double click the disk drive under Recovery Procedure (indicated in
yellow) in the Component Status Tag. Verify that the failure has
recovered.
