Chapter 2. IBM TotalStorage

Enterprise Storage Server

configuration

One benefit of a SAN is to implement disk pooling. To do this successfully,

we need an easy-to-manage storage server with a Fibre Channel attachment.

This is the IBM TotalStorage Enterprise Storage Server, 2105-F20, shown in

Figure 2-1.

First we introduce the ESS Web Interface, including the functions to maintain,

configure, and administer the ESS. Then we perform storage configuration.

We describe the configuration for an ESS using RAID 5 for use in a Fibre

Channel environment. These functions are described in a task-oriented manner.

We start with an unconfigured ESS and explain the configuration steps as we

progress through our configuration. The final goal is to gain access to the

volumes from Fibre Channel attached hosts.

In greater detail, we cover the configuration of the ESS disk groups, host Fibre

Channel ports (host FC ports), ESS Fibre Channel ports (ESS FC ports), and the

ESS logical volumes to be accessed from the host FC ports. We also modify

volume assignments and make changes to the host FC port definition.
