In many environments, it is common practice to use diskless servers, and boot the hypervisor or OS directly from SAN. UCS makes it very simple to configure a SAN boot policy for direct SAN boot. Make sure you have already configured appropriate vHBAs, and perform the following steps to configure a SAN boot policy for the server:

1. In the Server Boot Order tab of template configuration wizard, click on the + sign beside Create Boot Policy:

2. On the next pop-up window, provide a Name and Description for the new policy, expand the vHBAs section, and click on Add SAN Boot:

3. On the pop-up window, provide the name of the appropriate vHBA configured. Repeat the steps for primary and secondary vHBAs:

4. After adding vHBAs, Add SAN Boot Target, which was initially grayed out, will be highlighted. Click on Add SAN Boot Target:

5. On the pop-up window, add values for Boot Target LUN, Boot Target WWPN, and Type as Primary or Secondary. Contact the SAN administrator to get the appropriate information about the boot LUN designated for the SAN boot:
