3. You can verify the multipathing for the datastore by going to the Summary tab in the vSphere Client, as shown in Figure 5-94. Figure 5-94 Summary in vSphere Client 4. Right-click the datastore, and select Properties � Manage Paths, as shown in Figure 5-95. Figure 5-95 Manage Paths for datastore 346 SAN Boot Implementation and Best Practices Guide for IBM System Storage
5. You should see both paths in the Manage Paths dialogue window, as shown in Figure 5-96. Figure 5-96 Manage Path Policy For more information regarding SAN Boot for VMware, see the VMware (4.1) Fibre Channel SAN Configuration Guide document, at this website: http://www.vmware.com/pdf/vsphere4/r41/vsp_41_san_cfg.pdf 5.9 SAN Boot for Linux WIth the increasing trend towards implementing SAN Boot solutions, various distributions of Linux are being installed on external storage for SAN Boot environments. In the following sections, we describe two of the most widely used distributions of Linux, SUSE Linux Enterprise Server 11 SP 2 and Red Hat Enterprise Linux 5.5 (RHEL). Tip: Before setting up SAN Boot for Linux, review the information in 5.3.1, “Considerations before setting up SAN Boot” on page 286. Chapter 5.
