IBM System Storage N3700 A20
Setup
In this IBM Redpaper, we discuss how to set up clustered systems, using IBM®
System Storage™ N3700 Model 2863-A20 as an example. This paper covers:
Hardware setup, such as cabling and connecting to local area networks
(LANs) and expansion shelves such as the System Storage EXN2000
expansion unit
Initial setup of the cluster nodes and cluster configuration
Disk ownership in a clustered environment
We start our planning and installation procedure after unpacking and mounting
the systems in the 19" rack.
