forget lvlnboot - system doesn't start

[Konrad Hegner]

Hello

I had to activate a new mirroring and to cancel a old one (I had to move it from internal to external disks). And after this job I had forget to execute the lvlnboot commands (4 commands:
- lvlnboot -r /dev/vg00/lvol3
- lvlnboot -s /dev/vg00/lvol2
- lvlnboot -d /dev/vg00/lvol2
- lvlnboot -b /dev/vg00/lvol1 )

And I did a restart from the system and now the boot-sequence can't find the /stand/vmunix. So, I can't start the machine.
Know someone, how I can start the server anyhow? Thanks!

Hi,

in single user mode (interrupt the boot procedure ---> boot pri ---> y to interact with ISL ---> hpux -is)

ISL>hpux -lm
vgchange -y /dev/vg00
lvlnboot -r /dev/vg00/lvol3
lvlnboot -s /dev/vg00/lvol2
lvlnboot -d /dev/vg00/lvol2
lvlnboot -b /dev/vg00/lvol1

lvlnboot -R /dev/vg00
lvlnboot -v

and then reboot.

I hope this helps you.

Best regards,
Ettore

Sorry, I wrote too quickly...
go in maintenance mode, no single user mode:
after y to interact with ISL, just type

ISL>hpux -lm

and then commands above.

Best regards,
Ettore

Hello Ettore

You was definitively to fast, there is a error more (vgchange -a y ..), but it was anyway very helpful. Thank you.
Here is the complet procedure:

interrupt the boot procedure
--> boot pri
- boot with ISL --> y (yes)

ISL> hpux -lm
vgchange -a y /dev/vg00
lvlnboot -r /dev/vg00/lvol3
lvlnboot -s /dev/vg00/lvol2
lvlnboot -d /dev/vg00/lvol2
lvlnboot -b /dev/vg00/lvol1

lvlnboot -R /dev/vg00
lvlnboot -v (shows you all the settings)

reboot the system
