Removing disk shelves in systems running Data ONTAP 8.2
or earlier
If your system is running Data ONTAP 8.2 or earlier, you must halt your system to remove a disk
shelf.
Steps
1. Properly ground yourself.
2.
Shut down the storage system by entering the applicable command:
If your storage system is
operating in...
Then enter the applicable command...
7-Mode From the system console:
halt
Clustered ONTAP From the clustershell:
halt -node local
3. Verify that your system halted.
If your storage system has an LCD display, Halted should appear on the display; otherwise,
you should check the storage system console to ensure the system is halted.
4. Turn off the power switch on the disk shelf.
5. Unplug all power cords from the disk shelf.
6. Unplug and remove the cables connecting the disk shelf to the other disk shelves or the
controllers.
7. Use a Phillips screwdriver to remove the screws securing the disk shelf to the rack.
8. Remove the disk shelf from the rack.
To make the disk shelf lighter and easier to maneuver, remove the power supplies and I/O
Modules (IOMs). Avoid removing the disk drives or carriers if possible because excessive
handling can lead to internal damage.
You might want to use a mechanical hoist or lift if you are moving a fully loaded DS4243 or
DS4486 disk shelf.
Attention: If you must remove disk carriers from
the DS4486 disk shelf, do not place hands on the
two disk drive boards exposed on the underside of
the disk carrier.
CAUTION: A fully populated DS4243 or DS4246
disk shelf can weigh approximately 110 lbs (49.9
kg).
A fully populated DS2246 disk shelf can weigh
approximately 49 lbs (22 kg).
A DS4486 disk shelf with the two IOMs, four
power supplies, and only four disk carriers can
weigh approximately 82 lbs (37 kg). A fully
populated disk shelf can weigh approximately 150
lbs (68 kg).
