System doesn't boot

tarek_3 — Wed, 29 Jun 2005 01:37:34 GMT

Hi
I have a D280 Class (HP-UX 11i), recentely the slot of the scsi Card became defected , so i change the location of the scsi card, after this modification, i change the primary path to the new address of the boot disk and i boot the system into maintenance mode, i remove the lvmtab file and execute the vgscan, the lvmtab point now to the new hardware address of the boot disk. but the system doesn't boot yet
but if a boot the system into maintanace mode i see the following error ( can't open /dev/vg00/lvol1) and i can activate the volume group vg00 and i can boot the system to level three by executing the command init 3.
so i can boot the system manually (maintenance mode --> activate vg00 manually, run init 3),but the system can't boot automatically.
What should i do next ??
Regards
Hassoun

Hi Hassoun,

Could you post the output of

# lvlnboot -v

# setboot

Hi,

Can you make sure that root,boot and swap are pointing to the new disk address?

lvlnboot -v vg00

see if lvlnboot -v shows the boot,swap,root and dump correctly. It should display something like this if everything is fine.

lvlnboot -v
Boot Definitions for Volume Group /dev/vg00:
Physical Volumes belonging in Root Volume Group:
/dev/dsk/c0t5d0 (8/4.5.0) -- Boot Disk
Boot: lvol1 on: /dev/dsk/c0t5d0
Root: lvol3 on: /dev/dsk/c0t5d0
Swap: lvol2 on: /dev/dsk/c0t5d0
Dump: lvol2 on: /dev/dsk/c0t5d0, 0

If not update it using:

lvlnboot -b /dev/vg00/lvol1
lvlnboot -s /dev/vg00/lvol2
lvlnboot -r /dev/vg00/lvol3

Hope this helps

Hi
please find below the outout of the commands
# setboot
Primary bootpath : 8/8.9.0
Alternate bootpath : 8/16/5.0.0

Autoboot is ON (enabled)
Autosearch is ON (enabled)

# lvlnboot -v
Boot Definitions for Volume Group /dev/vg00:
Physical Volumes belonging in Root Volume Group:
/dev/dsk/c3t9d0 (8/8.9.0) -- Boot Disk
Boot: lvol1 on: /dev/dsk/c3t9d0
Root: lvol3 on: /dev/dsk/c3t9d0
Swap: lvol2 on: /dev/dsk/c3t9d0

and 8/8.9.0 is the new path

You probably still have the AUTO file in the boot (LIF) area hard coded to the the old disk location

You can verify this by the following command:

lifcp /dev/rdsk/cXtXdX:AUTO -

substitute your disk for cXtXdX

If the address is in the AUTO file, you will need to change it. I would recommend not hard coding the disk address but use one of the following commands:

mkboot -a "hpux" /dev/rdsk/cXtXdX

or if the system is mirrored run the following command against both boot disks:

mkboot -a "hpux -lq" /dev/rdsk/cXtXdX

Hi hassoun,

boot in maintenance mode,mv /etc/lvmtab, do vgscan
lvlnboot -b /dev/vg00/lvol1
lvlnboot -s /dev/vg00/lvol2
lvlnboot -r /dev/vg00/lvol3
will make boot,root and swap point to the new disk.
hope this helps

You might want to check the contents of /stand/bootconf as well.

hassoun --

What is the error you are getting when trying to boot ?

If you can boot in -lm, but not otherwise, then it could be a couple of things:

#1) your autoboot string does not point to the correct disk. This can be fixed with:

mkboot -a "hpux -lq" /dev/rdsk/c3t9d0

#2) Your lvlnboot info might be bad:

lvrmboot -a /dev/vg00
lvlnboot -s /dev/vg00/lvol2
lvlnboot -d /dev/vg00/lvol2
lvlnboot -r /dev/vg00/lvol3
lvlnboot -b /dev/vg00/lvol1

hi

the problem is fixed by re-executing lvlnboot commands

probably the best way to change the hardware path to the boot disk is to vgexport / vgimport the vg00 in lvm maintenance mode.
