booting with alternate path

[Ragni Singh]

Hello everyone,

I am getting this error message when I try booting off my alternate disk. Any ideas as to what is going on here.

WARN C7F0
IPL error: bad LIF magic

Hi

Looks like the lif is corrupt.

If you can boot from primary and recreate the mirror.

HP's system Admin tasks manual chapter 7.


1> pvcreate -B /dev/rdsk/xyz

2> vgextend /dev/vg00 /dev/dsk/xyz

3> mkboot /dev/rdsk/xyz

4> mkboot -a "hpux (;0) /stand/vmunix" /dev/rdsk/xyz

-a auto_file_string If the -a option is specified, mkboot
creates an autoexecute file AUTO on
device, if none exists. mkboot deposits
auto_file_string in that file. If this
string contains spaces, it must be quoted
so that it is a single parameter.

or use

4> mkboot -a "hpux -lq /stand/vmunix" /dev/rdsk/xyz

5> lvextend -m 1 /dev/vg00/lvol1 /dev/dsk/xyz -do this for all the lvols on root disk.

6> lvlnboot -R

7> lvlnboot -v To check if you see both the disks as boot disk.

My best guess is that you did not do a pvcreate -B and instead did a pvcreate. No boot area was reserved.

[Kevin Wright]

Yep, boot off the primary, and remirror to the alternate with pvcreate -B.

Hi Sanman:

This problem occurs when you have some problem reading the lif area of the disk. Did you do the pvcreate with -B ?

Also check and see whether you can boot with -lm mode with hpux.

Hi Sanman,

This usually indicates that the disk is bad.
Try booting from the primary & running diskinfo & even STM utils against that disk.

Hi Sanman,

ARe you able to boot through your second disk and get to the ipl prompt. If not then, your disk seems to be unbootable. try

bo alt
if your alt address is set to secondary disk, select y to interact with ipl.

at the ipl prompt, trye the boot command. If you are able to get to the ipl prompt and then while trying to boot it says bad lif magic, your bootstring is wrong. You can correct the same by booting manually and then using the command "mkboot"

You can also have a look at the link below for more help,

Hope this helps.

Trying reading the LIF area on the disk.

lifls /dev/dsk/c1t0d0

You should get something like:

ISL AUTO HPUX PAD LABEL

If there is no LIF area, you will get the error:

lifls: Can't list /dev/dsk/c1t0d0; not a LIF volume.
