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
This process is written for HP-UX 11.23 on an IA-64 server. There may be slight differences when
using this process with HP-UX 11.31 and the PA-RISC server. The installation media for HP-UX 11.23
should be readily available.
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 should be at least 60
GB, 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 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.
