Table 5-1 nPartition Boot and Reset Task Summaries (continued) Task Summary "Configuring Autoboot Options" • BCH Menu: the PATHFLAGS command from the BCH Configuration menu sets boot-time actions for an nPartition. To set the boot actions for an nPartition boot paths, enter: PATHFLAGS VAR action where VAR is the boot path variable (PRI, HAA, or ALT) and action is the boot action (0 for "go to BCH", 1 for "boot, if fail go to BCH", 2 for "boot, if fail try next path", or 3 for "skip this path, try next path"). • EFI Boot Manager: Boot Option Maintenance→Set Auto Boot TimeOut operation. • EFI Shell: autoboot command. For example: autoboot off to disable autoboot, or autoboot 60 to enable autoboot with a 60-second timeout period. • HP-UX: setboot -b on or setboot -b off command, to turn on (enable) or turn off (disable) autoboot. See "Configuring Autoboot Options" (page 158). "Configuring Boot-Time System Tests" • NOTE: HP recommends that all self tests be performed. • BCH Menu: Configuration menu FASTBOOT command: enter FASTBOOT to list settings; enter FASTBOOT RUN to enable all tests; enter FASTBOOT TEST RUN or FASTBOOT TEST SKIP to enable or disable an individual test. • EFI Shell: boottest command to list settings; boottest on to enable all tests; boottest off to disable all tests. To configure a specific test, use the boottest test on or boottest test off command. • HP-UX B.11.11: setboot -t testname=value to configure the test for all following boots, or setboot -T testname=value to configure the test for the next boot only. setboot -v to list settings. • HP-UX B.11.23 and B.11.31: setboot -t testname=value to configure the test for the next boot only. setboot -v to list settings. See "Configuring Boot-Time System Tests" (page 161). Troubleshooting Boot Problems On HP cell-based servers, you might encounter different boot issues than on other HP servers. The following boot issues are possible on cell-based servers. • Problem: On an HP Integrity server, HP-UX begins booting but is interrupted with a panic when launching the HP-UX kernel (/stand/vmunix). Causes: The nPartition ACPI configuration might not be properly set for booting HP-UX. In order to boot the HP-UX operating system an nPartition must have its acpiconfig value set to default. Actions: At the EFI Shell interface, enter the acpiconfig command with no arguments to list the current ACPI configuration for an nPartition. If the acpiconfig value is set to windows, then HP-UX cannot boot; in this situation you must reconfigure acpiconfig. To set the ACPI configuration for HP-UX: at the EFI Shell interface enter the acpiconfig default command, and then enter the reset command for the nPartition to reboot with the proper (default) configuration for HP-UX. 100 Booting and Resetting nPartitions
