Boot Time Troubleshooting

(Connect dumb terminal to serial console) Press and hold ESC at the beginning of the boot process. In the PDC (firmware processor dependent code), enter BO to boot. use ISL (initial system load), say yes. ISL prompt, enter : hpux -is

- 'hpux -lm' for maintenance mode also -lm = lvm maint mode, sometime -is won't work when lvm is corrupted. -lq = lvm, ignore failed mirror drive -ll = list content of /stand

Messages and the login prompt:

Boot : disk(scsi.6;0)/stand/vmunix 966616+397312+409688 start 0x6c50

Kernel Startup Messages Omitted

INIT: Overriding default level with level 's'

INIT: SINGLE USER MODE WARNING: YOU ARE SUPERUSER!! #

Hit F4 to toggle remote management on (with * on it). This makes serial console usable.

When booted in single user mode with corrupted fs, vgchange can be used to tell Veritas Vol Mgrt which device to use. This is sometime needed even in non-mirrored disk. vgchange -a y /dev/vg00 lvlnboot -v /dev/vg00

fsck -F vxfs -o full,nolog /dev/vg00/rvol8

----------------------------------------------------------------------------------------------------- clear out attention light in front panel thru serial console session (^B , enter 2x) get into gsp mode (Guardian Service Processor cli), give access to bios level control of the machine, view vfp (virtual front panel), clear hw err log, etc.

sl # sys log e # errors n # no filter q # quit co # exit back to console -----------------------------------------------------------------------------------------------------

Booting from CDROM may need to use this to find device path to use for booting.

BO boot, use default dev BO PRI boot, using primary (default) dev BO SEC boot, using secondary disk. Simple to do dual boot. BO 0/0/2/1.15 boot via specific path, see SEA.

IN enter info menu ALL display all info, machine model strings. eg 9000/800/A500-5X System Name: riptide is A-class. ME memory info

ISL commands

ISL - Initial System Loader Interactions in here allow boot into single user mode, etc. hpux -is # single user mode hpux -lm # LVM maintenance boot mode. hpux -lm /stand/vmunix.prev # boot via specific kernel hpux ll # list kernels avai in /stand
