Dear Sirs,

A lost the alternate harddisk beloning to my VG00 volume group in my rx8640 running hp-ux 11.23. I have replaced it and trying to restore the mirror.

when i get to the command

#vgcfgrestore -n /dev/vg00 /dev/rdsk/c2t6d0

I get the following response:

Configuration info for Physical Volume "/dev/rdsk/c2t6d0" not found
in "/etc/lvmconf/vg00.conf" :
Character-special file for PV not supplied on command line, OR
PV did not belong to Volume Group /dev/vg00 when configuration file was created.
You have mail in /var/mail/root.

The content of /etc/lvmconf/vg00.conf is as follows:

#strings /etc/lvmconf/vg00.conf
CONFIG01
/dev/vg00
/dev/rdsk/c0t6d0s2
/dev/rdsk/c2t6d0s2
LVMREC01
HPLVMBDRE
LVMREC01
HPLVMBDRE
VGDA0001
VGSA0001E

i am locked so i need your urgent help.

Thank you very much.

Dear All

Thanks for all your contributions. Now my last hurdle is, when i do the command below, i get the attached response.

#lvextend -m 1 /dev/vg00/lvol1 /dev/dsk/c2t6d0

lvextend: Physical volume "/dev/dsk/c2t6d0" does not belong
to volume group "/dev/vg00".

Someone should help me.

Thanks.

This is the result.

#lvextend -m 1 /dev/vg00/lvol1 /dev/dsk/c2t6d0s2

lvextend: "MirrorCopies" parameter "1" must be larger than existing number "1".

Ooops...!!
Sicne you are REPLACING the mirror disk,this step is not required.
Just do

#vgsync /dev/vg00

ZhouChong — Mon, 13 Sep 2010 12:47:55 GMT

Maybe need reduce the VG and extend again

Dear All,

I did " vgsync /dev/vg00 " and it worked like magic.

Thank you all for your wonderful help.
