September 2015
• Updated "About this task" sections in several procedures to include
recommendations for cable minimum bend radius and use of Velcro ties for
bundling cables.
• Updated the "Replacing shelf components" and "Hot-adding a SAS disk
shelf" procedures to include the best practice for having the most current disk
shelf, disk drive, and if applicable, ACP firmware on all disk shelves in the
system before adding new hardware components.
• Updated the "Hot-removing disk shelves or stacks in systems running Data
ONTAP 8.2.1 or later" procedure "Before you begin" section to include the
prerequisite for reassigning epsilon on clustered Data ONTAP systems with
more than two nodes.
• Updated the "Changing the disk shelf ID" procedure "About this task" section
to state that, although Data ONTAP 8.3 made 99 available as a valid shelf ID,
99 cannot be used because of a bug.
• Updated the "Hot-swapping a disk drive or carrier" procedure to include a
step for assigning disk ownership.

Feature updates
January 2015
• Updated the "What the disk shelf LEDs mean for DS4243, DS2246, and
DS4246 disk shelves" section to add a note that because of a bug, in some
versions of Data ONTAP, when a disk drive fails due to excessive link errors,
adapter errors, or timeouts, the fault LED does not illuminate.
• Updated the "Hot-swapping or replacing an IOM" procedure to include the
requirement that your system must be running Data ONTAP 8.1.4 or later,
Data ONTAP 8.2.1 or later, or Data ONTAP 8.3 or later to hot-swap an IOM.
• Updated the "Changing the disk shelf ID" procedure note in Step 8 to state
that if you decide to change the shelf ID after your storage system is running
Data ONTAP, you must wait at least 70 seconds (instead of 30 seconds)
before turning the power back on to complete the power cycle.
• Modified the "Installing SAS disk shelves in a new HA pair or single-
controller configuration" procedure to remove shelf power on and checking
shelf ID steps, which are now part of the "Cabling disk shelves in a new HA
pair or single-controller configuration" procedure in the SAS and ACP
Cabling Guide for DS4243, DS2246, DS4486, and DS4246 Disk Shelves .
The "Installing SAS disk shelves in a new HA pair or single-controller
configuration" procedure was modified to coincide with the steps in the
platform "Installation and Setup Instructions" that ship with new platforms.
You are instructed to power on disk shelves and check IDs after cabling SAS
and ACP connections rather than before.

• Included the procedure for shelf hot-removal, which is supported on
multipath HA and single-controller dual path 7-Mode and clustered Data
ONTAP systems running Data ONTAP 8.2.1 or later.
• Included the acpadmin configure command, which is used when enabling
the ACP capability on systems running Data ONTAP 8.2.1 or later.
The options acp.enabled on command is used to enable the ACP
capability on systems running versions of Data ONTAP prior to 8.2.1.
