Storage Array Configuration
The following instructions are for the MSA2000. It has a built-in browser-based management
interface called SMU (Storage Management Utility). The device can also be configured using the CLI.
This document has instructions to use the CLI to configure the IP address, then the remainder of the
configuration steps are shown using SMU.
In this section there are instructions for creating external shared storage to be used for the cluster lock
and for package data.
Connecting the MSA2000 to the Servers
Once the OS has been installed on each server, plug the Fibre Channel cables from the MSA2000
into each server. Make sure the green lights on the cards and controllers are on. If not, double check
that the cables are completely plugged in. See Figure 2 for the wiring specification.
To avoid a single point of failure (SPOF), a path from each server to each storage controller should be
created, providing two paths from each server. The MSA2000 has a feature called “host port
interconnects” that provides high availability using internal connections between the host ports,
providing redundancy in the event that one controller fails. This feature will be configured in a later
step.
Plug in the Fibre Channel cables as follows:
1. Host 1 – plug 2 Fibre Channel cables from the dual channel HBA to the MSA2000 to
a. Controller A Port 0
b. Controller B Port 0
2. Host 2– plug 2 Fibre Channel cables from the dual channel HBA to the MSA2000 to
a. Controller A Port 1
b. Controller B Port 1
