. In the Define Additional Mapping window, choose the desired host from the drop-down menu. Next, for the boot LUN, choose LUN 0 (zero), as shown in Figure 6-33. Figure 6-33 Assign Host Important: The boot logical volume must have LUN ID 0 to be able to boot the operating system, c. In the Mappings Window, you should be able to see the newly created Boot LUN in the Defined Mappings frame, as shown in Figure 6-34. Figure 6-34 Boot LUN mapped to the host 424 SAN Boot Implementation and Best Practices Guide for IBM System Storage
Verify the properties of the LUN, then proceed to 6.4.3, “Additional host configuration” on page 427 Tip: If you have multiple LUNs mapped to this host, delete all mappings and make sure that the boot disk has LUN number 0 and is not mapped to other hosts. Also, the access LUN must not be mapped to the host at this stage because it will be seen by the host as storage. After the OS and failover driver installation, you might need to enter the mapping again in order to map additional data disks to your host. Configuring the secondary path for failover We now proceed with setting up the secondary path to the storage that will provide failover in the event of a failure of the primary path. Initial preparation Perform the following tasks: 1. Connect the second iSCSI cable to the second iSCSI port on the server. 2. Enter the BIOS of the second port as shown in and set the IP settings for the second HBA path as were performed for the primary path. Configuring the secondary path to the DS5000 storage subsystem To configure the secondary path to the DS5000 storage subsystem, perform these tasks: 1. In Storage Manager mapping view, select the host and define the second host port of the server to be part of the storage partition as seen in Figure 6-35.
