Obtaining The Data Ontap Software From The Ibm Nas Website - IBM N Series Hardware Manual

Upgrading Data ONTAP software requires several prerequisites, installing system files, and
downloading the software to the system CompactFlash. Required procedures might include
the following steps:
Update the system board firmware (system firmware).
To determine whether your storage system needs a system firmware update, compare the
version of installed system firmware with the latest version available.
Update the disk firmware.
When you update the storage system software, disk firmware is updated automatically as
part of the storage system software update process. A manual update is not necessary
unless the new firmware is not compatible with the storage system disks.
Update the Data ONTAP kernel.
The latest system firmware is included with Data ONTAP update packages for
CompactFlash-based storage systems. New disk firmware is sometimes included with
Data ONTAP update packages. For more information, see the Data ONTAP Upgrade
Guide at:

There are two methods to upgrade storage systems in an Active/Active configuration:
Nondisruptive
The nondisruptive update method is appropriate when you need to maintain service
availability during system updates. When you halt one node and allow takeover, the
partner node continues to serve data for the halted node.
Standard
The standard update method is appropriate when you can schedule downtime for system
updates.
Upgrading Data ONTAP for a single node always requires downtime.
