16 Controlling server access to volumes Application servers (servers), also called clients or hosts, access storage volumes on the SAN using the iSCSI protocol. You set up each server that needs to connect to volumes in a management group in the CMC. We refer to this setup as a "server connection." Server connections can be single servers or server clusters. Use server clusters in the CMC to easily assign volumes to the clustered application servers that are accessing the SAN storage volumes. For example, create two servers and cluster them to assign two volumes to a Microsoft Exchange cluster or VMware ESX Server simultaneously. You can set up servers to connect to volumes in three ways. All three ways use the virtual IP (VIP) for discovery and to log in to the volume from a server's iSCSI initiator: • iSCSI with VIP and load balancing-Use the load balancing option when you set up a server connection in the CMC to balance connections to the SAN. • Microsoft DSM or HP P4000 DSM for MPIO (if using)-Automatically establishes multiple connections to the SAN. • iSCSI with VIP only. NOTE: Before setting up a server connection, make sure you are familiar with the iSCSI information in Chapter 19 on page 299. Setting up server connections to volumes requires the general tasks outlined below. Table 57 Overview of configuring server access to volumes Do This For More Information Ensure that an iSCSI initiator is installed on the server. If you are using the HP P4000 DSM for MPIO, ensure that both the Microsoft MPIO and the DSM for MPIO are installed on the server. Refer to the HP StorageWorks P4000 Windows Solution Pack User Manual. In the CMC, add the server connection to the management group and configure iSCSI access for that server. See "Adding server connections to management groups" on page 258. [Optional] Cluster multiple servers in the CMC to connect multiple volumes to clustered application servers. See "Creating a server cluster" on page 261. In the CMC, assign volumes to the server or server See "Assigning server connections access to cluster. volumes" on page 264. In the iSCSI initiator on the server, log on to the volume. See "Completing the iSCSI Initiator and disk setup" on page 267. On the server, configure the volume using disk management tools. See "Completing the iSCSI Initiator and disk setup" on page 267.
