Storage Array Configuration

Before a host iSCSI initiator and an iSCSI-based storage array can communicate, they must be configured with information such as which IP addresses and authentication method to use. Since iSCSI initiators establish connections with an already configured storage array, the first task is to configure your storage arrays to make them available for iSCSI initiators.

This utility requires network access to the management ports of the storage arrays you wish to configure. You must have a properly functioning network infrastructure before attempting to configure your storage arrays. If your storage arrays are already configured, you can skip directly to the host configuration.

This configuration task generally involves the following steps:

1.Discover available storage array(s) for configuration.

2.Select a storage array to configure.

3.Set a storage array name and password.

4.Configure the IP protocols and addresses for the management ports.

5.Configure the IP protocols and addresses for the iSCSI ports.

6.Specify the CHAP authentication method.

7.Apply the settings after reviewing the summary.

8.Repeat the procedure starting from step 2 to configure additional arrays.

Host Configuration (Host Connectivity Configuration)

After you have completed configuring your iSCSI-based storage arrays, the next task is to run this utility on all hosts that need to access the storage arrays. Depending on your network configuration, your host may be the same machine you use to manage your storage arrays, or it may be on a completely separate network.

The option to configure a host is disabled if the machine the utility is running on does not have an iSCSI initiator or the required driver components installed. When the option is disabled, the utility also displays an informational message. If you are running the utility on a host which is not connected to the iSCSI based storage array (or which you do not wish to connect to the array), the informational message can be ignored.

The task involves the following steps:

1.Discover available storage array(s) for connection.

2.Select a storage array.

3.Specify the CHAP secret.

4.Select the iSCSI ports the host's initiator uses to log on.

5.Repeat the process starting from step 2 to connect to additional arrays.

6.Repeat these steps on each host that needs access to the storage array(s).

Before Starting The Configuration Process

Before you start configuring the storage array or host connectivity, it is recommended that you fill out the iSCSI configuration worksheet to help you plan your configuration. You may need to use several worksheets depending on your configuration.

Keep the following guidelines in mind for the storage array and host configuration:

•For optimal performance, ensure your network configuration is valid. See the storage array's Support Matrix at support.dell.com/manuals.

•If your host has multiple network interfaces, it is recommended that each network interface uses a separate subnet.
