7 Boot from SVSP devices

This chapter outlines the process for booting from the SAN with the various operating systems

supported by the SAN Virtualization Services Platform (SVSP). Please see the http://

h18006.www1.hp.com/storage/networking/bootsan.html website for a link to detailed boot from

SAN documentation, where application notes are available for each operating system.

Boot from SAN with AIX

Not currently supported as of the publication date for this document.

Boot from SAN with HP-UX

Boot from SAN is not supported for HP-UX 11.23. This process is for HP-UX 11.31.

1. Check the firmware level on the Itanium server to be used for booting from SAN.

a. On the console (connected via serial or the MP LAN) press Ctrl-B to get to the management

processor main menu.

b. Enter cm to get to the Command menu.

c. Enter the command sysrev to display the current firmware revision levels of all

components in the system.

d. Verify that the system firmware is the latest available.

e. If necessary, obtain updated firmware from http://patch-hub.corp.hp.com/wtec/catalog/

and install the firmware on the server.

2. Configure and present one virtual disk from SVSP to the server. The LUN size should be at

least the minimum size required by the operating system, and should have only one path to

the server. Disable DPMs, disable switch ports, or change zoning as appropriate to eliminate

all but one path from the server to the virtual disk.

3. On the server, perform an ioscan to make sure the virtual disk just presented is visible to the

server. For example, use the command ioscan -fnC disk.

4. If the server was installed and booted previously, and the same network settings are to be

reused, print or write down the contents of the /etc/rc.config.d/netconf file. The

content of this file will be needed to reconfigure the network settings for the LAN cards after

the OS is installed and the server is booted from the SAN.

5. Insert disk 1 of the OS media into the server's DVD drive, and reboot the server from the install

media. When the server comes up to the boot menu, select the internal DVD-ROM as the drive

from which to boot. The boot menu is a timed menu; press any key to stop the timer. Then

select the internal DVD-ROM drive and continue booting.

6. When prompted for the location of the root disk, select the FC device. There should be only

one shown, provided only one path exists to the SAN volume.

7. Continue installing the OS on the new root disk. If previous network settings are not being

reused, configure the network settings when prompted during the OS install and setup.

8. If previous network settings are being reused, wait until the OS installation has been completed.

file to configure the LAN interfaces for the newly installed OS.

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).

11. Verify that all paths are properly discovered and redundancy is restored.
