Assumptions This section is based on the assumption that the following basic gateway setup
has already been completed and tested:
◆
You have completed the basic system setup (setup script).
◆
Data ONTAP software was installed.
◆
You verified that the paths to existing storage were set up correctly.
◆
If the system is an HA pair, you have verified that takeover works.
High-level steps The following table lists the major steps for adding a new disk shelf and provides
information about where you can find detailed procedures.
Step Action Details
1 Review the restrictions for adding
disk shelves. See the following guides:
◆
Appropriate Storage Expansion Unit Hardware
and Service Guide
◆
Data ONTAP High Availability Configuration

2 If you plan to use Multipath Storage
with an HA pair and this is the first
disk shelf in the loop, set the
environment variable required for the
gateway with Multipath Storage.
Note
This step must be performed before
connecting the first disk shelf in a
loop to the gateway.
See “ Configuring the gateway environment variable
for Multipath Storage ” on page 71.
