Hot-swap hardware: The storage subsystem contains hardware that enables
you to replace a failed hard disk drive without turning off the storage subsystem.
You can continue to operate the storage subsystem while a hard disk drive is
being removed or installed. These drives are known as hot-swap hard disk
drives.
Removing a hard disk drive
To remove a hot-swap hard disk drive, complete the following steps.
Note: The hard disk drive comes installed in a drive tray. Do not attempt to detach
the drive from the tray.
1. Use Table 15 on page 142 to record the location and identify the hard disk
drives. Record this information so that you can replace the hard disk drives in
the same bays from which you removed them.
2. Read the safety information that begins on page xiii and “Best practices
guidelines” on page 5.
Attention: Never remove a hard disk drive when its green activity LED is
flashing. Remove a drive only when its amber status LED is lit (not flashing),
when the drive is inactive (activity LED is off), or when the storage subsystem is
turned off.
3. (DS3512 and EXP3512) Remove the hard disk drive.
a. Press the latch on the end of the tray handle to release it, then pull out the
tray handle to the open position.
b. 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.
4. (DS3524 and EXP3524) Remove the hard disk drive.
