Chapter 5. Hardware replacement procedures
Hot-swapping an internal disk drive
When a disk drive fails, the storage system logs a warning message to the system console indicating which
disk drive failed, the fault LED on the operator display panel illuminates, and the fault LED on the failed disk
drive illuminates. You can hot-swap a disk drive while the system remains powered on.
About this task
How you hot-swap the disk depends how the disk drive is being used. By using the correct procedure, you
can prevent unwanted AutoSupport notifications from being generated. Depending on your context, disk
drives with Storage Encryption might require additional steps before and after the hot-swap. See the
applicable Data ONTAP storage management guide for information about the commands that apply to your
context.
See the
Lenovo Press
for information about supported disk drives.
When replacing several disk drives, you must wait one minute between the removal of each failed disk drive
and the insertion of the replacement disk drive to allow the storage system to recognize the existence of
each new disk.
Note: Always use two hands when removing, installing, or carrying a disk drive.

Step 1.
Properly ground yourself.
Step 2.
Gently remove the bezel from the front of the system.
Step 3.
Physically identify the failed disk drive from the system console warning message and the
illuminated fault LED on the disk drive.
Step 4.
Press the release button on the disk drive face. Depending on the storage system, the disk drives
have the release button located at the top or on the left of the disk drive face.
For example, the following illustration shows a disk drive with the release button located on the left
of the disk drive face.
The cam handle on the disk drive springs open partially and the disk drive releases from the
midplane.
