state or to place the array that is associated with the drive (or drives) in an
offline state before you remove the drive from the storage subsystem.
Attention: Failure to replace a hard disk drive in its correct bay might result in
loss of data. If you are replacing a hard disk drive that is part of a configured array
and logical drive, be sure to install the replacement hard disk drive in the correct
bay. See the hardware and software documentation that comes with the DS3300 to
determine whether there are restrictions regarding hard disk drive configurations.
To replace a hot-swap hard disk drive, complete the following steps:
1. Read the safety information that begins on page xi and "Best practices
guidelines" on page 6.
2. Use the DS3000 Storage Manager software to print a new storage system
profile.
Attention: Never hot-swap a drive when its associated green activity LED is
flashing. Hot-swap a drive only when its associated amber status LED is lit and
not flashing.
3. Remove the drive:
a. Press the latch on the right end of the tray handle to release it.
b. Pull the tray handle out into the open position.
c. Pull the drive approximately 12 mm (0.5 in.) out of the bay and wait 70
seconds to allow the drive to spin down and the storage subsystem
controller to recognize that a drive is removed from the configuration.
Make sure that there is identification (such as a label) on the drive, and then
slide it completely out of the storage subsystem.
Attention: After you remove a drive, wait 70 seconds to allow the drive to
spin down before you replace or reseat the drive. Failure to do so might cause
unpredictable results.
4. Unpack the new drive. Save all packing material in case you have to return the
drive.
Note: Use Table 9 on page 106 to make sure that you replace the hard disk
drive into the correct bay.
5. Install the new drive:
a. Press the latch on the right end of the tray handle to release it.
b. Pull out the tray handle to the open position.
c. Gently slide the drive all the way into the empty bay until the drive stops.
d. Push the tray handle into the closed (latched) position.
e. Wait 30 seconds for the system discovery process to be completed.
6. Check the drive LEDs:
v When a drive is ready for use, the green activity LED is lit and the amber
status LED is off.
v If the amber status LED is lit and is not flashing, remove the drive from the
unit and wait 70 seconds; then, install the drive again.
7. Make sure that the drive is shown in the DS3000 Storage Manager Subsystem
Management window.
Note: If you are replacing more than one hard disk drive, replace only one drive at
a time.
