Replacing disk shelves
You can replace a disk shelf in an HA pair or single-controller system with a fully populated disk
shelf or a disk shelf chassis for which you will transfer components from the shelf you are
removing. You must halt your system to replace a disk shelf.
Before you begin
The disk shelf model you are installing must meet the storage system requirements specified in the
Hardware Universe, which includes supported shelf models, supported disk drive types, maximum
number of disk shelves in a stack, and supported Data ONTAP versions.
About this task
•
If you are installing DS4486 disk shelves, you must have read and understood the "Rules for
handling disk carriers for DS4486 disk shelves" section to prevent damage to the disk drives in
the disk carriers.
•
DS4486 disk shelves are shipped with all but four disk carriers removed to make the disk shelf
lighter and easier to install into a rack.
The four disk carriers might contain the Data ONTAP root volume and should remain in the
disk shelf. Because you must insert the remaining disk carriers into the disk shelf after it is
installed into the rack, additional handling could damage disk drives in the disk carriers if they
are not handled correctly.
•
To prevent degraded performance, do not twist, fold, pinch, or step on the cables.
Cables have a minimum bend radius. Cable manufacturer specifications define the minimum
bend radius; however, a general guideline for minimum bend radius is 10 times the cable
diameter.
•
Using Velcro wraps instead of tie-wraps to bundle and secure system cables allows for easier
cable adjustments.
