Precautions when replacing a drive
The procedure for replacing a drive varies, depending on the spare drive
setting, RAID configuration, data recovery setting mode, and spare drive
operation mode (variable or fixed).
Observe the following guidelines when replacing a drive.
•
Back up all data before replacing a drive in a RAID 0 configuration.
Otherwise, the user data on the drives being replaced will be lost.
•
Drives are replaced only while power to the storage system is on.
Complete the drive replacement within 10 minutes. Otherwise, an
abnormal rise in temperature can power off the storage system.
•
To prevent part failures caused by static electrical charge built up on
your body, wear a wrist strap connected to the storage system before
starting and do not remove it until you finish. Otherwise, the static
electrical charge on your body might damage the drive or other
hardware components.
•
When you install a disk drive, support its metal frame with one hand
and touch the metal frame with the hand that is wearing the wrist
strap, as shown in
Support the part
by touching its
metal part (metal
plate) with your
fingers.
•
Drives are precision components and should not be exposed to shock or
rough movements.
•
When you install a drive, hold it by its metal part using your hand that
has the wrist strap. To discharge static electricity, touch the metal
plate.
•
If you replace drives #0 to #4 on the CBXSS/CBXSL/CBSS/CBSL, or
drives #0 to #4 on the DBS/DBL Drive Box corresponding to unit ID#0
on the CBL, do not remove drives #0 to #4 at the same time when the
storage system power is turned on. Otherwise, the storage system
might go down.
•
If you receive an alert about other problems with the storage system
either prior to or after installing the drive, perform the maintenance
procedures in the alert until the problem is corrected.
•
Store the collected simple trace information on CD-R (see
trace information on page
