Replacing A Disk Drive; Tools Needed; Before You Begin - Hitachi AMS 2000 Series Service Manual

Replacing a disk drive

The hot-swappable feature of the Hitachi Data Systems AMS 2000 storage
systems allows disk drive replacement with the array power ON. This
procedure describes how to replace a disk drive when the array power is on.

Tools needed

• Anti-static wrist strap
• Navigator 2

Before you begin

Before replacing a disk drive, read the following information.
CAUTION! Back up all user data before replacing a disk drive in the
RAID 0 configuration or when a spare disk is not set. When the
RAID group and logical unit are deleted or formatted, related user
data will be lost.
Disk drives must be removed and replaced with the power on.
When hot-swapping parts, do not leave any slot in the array open
for more than ten minutes. Otherwise, the loss of cooling air could
cause the unit to overheat and shut down.
Wait at least 20 seconds after removing a part from the system
before replacing it.
Do not replace any parts while the green Ready LED on the front of
the base unit is blinking at high speed because the firmware is
being downloaded at that time. Wait until the Ready LED is ON
before replacing parts. Note that the download can take as much
as 30 to 50 minutes on an AMS 2100/2300 or 40 to 60 minutes for
an AMS 2500.
