lvlnboot: Unable to query the io interface

[Ian Killer_1]

Hi experts... I got another curly one for you. Below is two outputs from lvlnboot. If it pass it vg00 as a parameter it works, but without a parameter it errors. Please help.

root # lvlnboot -v
Boot Definitions for Volume Group /dev/vg01:
Physical Volumes belonging in Root Volume Group:
/dev/dsk/c0t1d0 (10/0.1.0)

hi,

my guess is that your /etc/lvmtab is corrupt.

- mv /etc/lvmtab /etc/lvmtab.prev
(do not delete, might need to put it back)
- vgscan -a
- lvlnboot -v
- vgdisplay -v
- if all OK, then keep the new lvmtab
- if NOT OK, put /etc/lvmtab.prev back

good luck,
Thierry.

Thanks Thiery....

I forgot to mention that I've already tried the following ...

mv /etc/lvmtab /etc/lvmtab.old
vgscan
rm /dev/dsk/c*
rm /dev/rdsk/c*
insf -e

... and the problem remains.

If you don't specify any VG then lvlnboot queries all of them. So the question is, if your vg01 is a bootable VG at all.

If not (i.e. you use only vg00 for booting), then try "lvrmboot -r vg01".

Best regards...
Dietmar

Thanks Dietmar...
One of my disk in vg01 has a boot sector on it. vg01 is also the first vg in lvmtab and that's because the first disk in h/w paths belongs to vg01.

The system always booted fine and now reports on the vg01 first when executed without a parameter.

Thanks again.
