Hi All,

Facing a problem!!!! Need your help...

Actually IN bdf Output am getting

/dev/root instead of /dev/vg00/lvol3...

--> have checked /etc/mnttab and there i found the wrong entry....
--> also have checked lvlnboot -v output and there i found the following output:-

----------------
{root}# lvlnboot -v vg00
Boot Definitions for Volume Group /dev/vg00:
Physical Volumes belonging in Root Volume Group:
/dev/dsk/c0t6d0 (0/0/0/2/0.6.0) -- Boot Disk
/dev/dsk/c2t6d0 (0/0/0/3/0.6.0) -- Boot Disk
Root LV not yet configured !! Mirror information will not be displayed
Boot: lvol1 on: /dev/dsk/c0t6d0
No Root Logical Volume configured
No Swap Logical Volume configured
No Dump Logical Volume configured
------------------

So, Need your help to correct it.

Appreciate your help and support as always.

Thanks in advance..

Hello MIKAP,

Thanks a lot for your quick response ....

but have followed the steps i.e.

{root}# mv mnttab mnttab.13042010
{root}# mount -a
{root}# bdf

but still its showing /dev/root on / .

Do I need to take reboot or need to do something else.... and the scenario that you have shown me via link given above... is showing proper output of lvlnboot -v....

and in my case it showing

{root}# lvlnboot -v vg00
Boot Definitions for Volume Group /dev/vg00:
Physical Volumes belonging in Root Volume Group:
/dev/dsk/c0t6d0 (0/0/0/2/0.6.0) -- Boot Disk
/dev/dsk/c2t6d0 (0/0/0/3/0.6.0) -- Boot Disk
Root LV not yet configured !! Mirror information will not be displayed
Boot: lvol1 on: /dev/dsk/c0t6d0
No Root Logical Volume configured
No Swap Logical Volume configured
No Dump Logical Volume configured

So, Need your assistance and help on this.

Thanks

Are you sure ur server is in RL 3 or 5.
Cause I suppose / is mounted on /dev/root whenin maintenance.
