Deployment Guide 21

Before You Begin

Verify that the following tasks have been completed for your cluster:

• All hardware is installed in the rack.

• All hardware interconnections are configured.

• All virtual disks/LUNs, RAID groups, and storage groups are created on the

storage system.

• Storage groups are assigned to the cluster nodes.

CAUTION: Before you perform the procedures in the following sections, ensure

that the system hardware and cable connections are installed correctly.

Cabling Your SAS Storage System

Because SAS clusters can only be installed in a direct-attached cluster, they

are limited to two nodes only.

To configure your nodes in a direct-attached configuration (see

Figure 1-4

complete the following steps:

Connect one SAS cable from a port of the SAS controller of node 1 to the

In-0 port of RAID controller 0 in the MD3000 RAID enclosure.

Connect one SAS cable from a port of the other SAS controller of node 1

to the In-0 port of RAID controller 1 in the MD3000 RAID enclosure.

Connect one SAS cable from a port of the SAS controller of node 2 to the

In-1 port of RAID controller 0 in the MD3000 RAID enclosure.

Connect one SAS cable from a port of the other SAS controller of node 2

to the In-1 port of RAID controller 1 in the MD3000 RAID enclosure.
