[de.joe_1]

HI ALL,
when i install the system in hp9000(b2600),my system reboot at all time , i see the words before the reboot : no dump space...

thaks!

Hi,

Not having dump space shouldn't cause the system to reboot. System was trying to dump the image after it crashed and it was not able to do so as the dump space is missing. You should be seeing other messages. Post them.

Try bringing it up in LV maintenance mode. When the system reboots, press any key to put it in to bootadmin prompt. Then interact with IPL

Main Menu: bo pri
Interact with IPL:y

ISL> hpux -lm

Once you got the prompt, do

#vgchange -a y vg00
#lvlnboot -b /dev/vg00/lvol1
#lvlnboot -r /dev/vg00/lvol3
#lvlnboot -s /dev/vg00/lvol2
#lvlnboot -d /dev/vg00/lvol2
#lvlnboot -R
#lvlnboot -v

Ensure that all the above logical volumes appear. Then reboot it again..

Much before login screen appears system goes through several other settings and startup scripts.

When you see the message "strike a key within 10 seconds to interrupt boot sequence"
When you do this you get ISL prompt.Then follow Sri's post.

When you get into single-user mode, check the inittab file to see if an init state of 6 is in the file. The init state 6 tells the system to reboot.

Try disconnecting anything externnal from the machine and attempt to boot up again.

If you can get into single user mode without any reboots then boot into single user mode and mount /var and /tmp then run : savecrash -v /var/adm/crash.

This should put an entry into /etc/shutdownlog as well as create a crash dump.

Post that message here and maybe we can tell why wer're failing.
