The system provides SAN boot support for HP 9000 and HP Integrity servers.
SAN boot is supported for all HP-UX 11.3x releases on both HP 9000 and HP Integrity servers. See the Hewlett-Packard publication, HP-UX System Administrator's Guide, for details.
For the HP-UX operating system, use HP PVLinks (physical volume links) as the multipathing software on the boot device. PVLinks or the Subsystem Device Driver (SDD) provides the multipathing support for the other devices that are attached to the system.
For HP Integrity servers, the HP-UX operating system creates a primary boot partition after the operating system installation on a system volume. This primary boot partition is created as the default. The primary boot is the upper line of the setboot menu at the MP Server console. The boot starts in 10 seconds unless an interruption occurs, which is the same as in a normal boot. You can change the alternative boot partition, change the boot order, or add a boot disk by using the console boot menu. Use the setboot command to list, add, or change the primary boot or an HA alternative boot, which is an alternative boot from an operating system that is booted already.
Use OpenVMS Extensible Firmware Interface (EFI) utilities to update firmware for a host or host bus adapter (HBA) or to check for the connected SAN disks.
