HP StorageWorks SAN Virtualization Services Platform administrator guide (5697-0109, July 2009)

9. Ping a known IP address to confirm network connectivity. It may be necessary to wait several
minutes for the DNS registration on the network to complete before a ping works or the newly
booted server is reachable from a remote platform on the network.
10. Restore all paths from the new boot LUN to the server (re-enable DPMs, re-enable switch ports,
or change zoning back to the original configuration as appropriate to restore all paths from the
server to the new boot LUN).
Boot from SAN with Linux
See the HP StorageWorks Booting Itanium Linux systems from a storage area network application
notes for detailed instructions. This document is available from a link at http://h18006.www1.hp.com/
storage/networking/bootsan.html. In addition, follow these guidelines:
• Ensure you are using the latest Extensible Firmware Interface (EFI) firmware and drivers.
• Zoning should be set up so that the boot from SAN LUN only sees one path.
• See the HP StorageWorks SAN Virtualization Services Platform Manager user guide for instructions
on creating SVSP LUNs.
• Make sure to install the full feature DSM, and then modify the zoning to enable both paths to see
the boot from SAN LUN.
Boot from SAN with VMware
This information can be found in the VMware Basic System Administration Guide located at http://
www.vmware.com/pdf/vi3_35/esx_3/r35u2/vi3_35_25_u2_admin_guide.pdf. Using this guide,
the process is outlined as follows:
1. Create the virtual machine as described in the chapter titled “Creating Virtual Machines.”
Specifically, follow the instructions in the section titled “Creating Typical Virtual Machines.”
NOTE:
Using the steps in this procedure, select the Guest OS to be used on the virtual machine.
However, the OS is not installed until later.
2. Map a LUN to the virtual machine as described in the chapter titled “Creating Virtual Machines.”
Specifically, follow the instructions in the section titled “Mapping a SAN LUN.”
NOTE:
The ESX Server has two methods of presenting SAN storage to virtual machines:
• With disk files, a virtual machine can use part of a VMFS-formatted virtual disk on a
presented SAN LUN as its storage drive. This option allows you to have multiple machines
boot from the same LUN, where each machine has its OS installed on that LUN.
• A virtual machine can use an entire unpartitioned LUN as a RAW device and put its
own partition and file system on the entire LUN.
3. Install the Guest OS as described in chapter 10 titled “Creating Virtual Machines.” Specifically,
follow the instructions in the section titled “Installing a Guest Operating System.”
4. After completion of the OS install, power on the virtual machine. It will boot from the SAN volume.
