he device file /dev/rroot does not exist or is not correct

[Gouranga Maiti]

Hi all,
My server has mirror OS disk with HP-UX 11.11. I unmirrored OS disk, then remove from vg00 and restore ignite-ux of 11.00 from different hawdware (selecting clone on different HW=true during restoration).

Now during booting I am facing the following problem:---
1. booting from 11.11 disk without any problem. but

2. when trying to boot from new installed 11.00 disk, it is giving following error:----

could you please suggest how I will resolve "device file /dev/rroot does not exist or is not correct" problem.

Thank you all in advance..

[Steven E. Protter]

Shalom,

More than likely the mirror process was not correctly completed.

Here is my guide on the subject:

pvcreate -B /dev/rdsk/c1t0d0 #use real disk

mkboot -l /dev/rdsk/c1t0d0
mkboot -a "hpux -lq (;0)/stand/vmunix" /dev/rdsk/c1t0d0 # use real disk


# mkboot -b /usr/sbin/diag/lif/updatediaglif -p ISL -p AUTO -p HPUX -p PAD -p LABEL /dev/rdsk/c?t?d?

If you are running 64-bit OS:

# mkboot -b /usr/sbin/diag/lif/updatediaglif2 -p ISL -p AUTO -p HPUX -p PAD -p LABEL /dev/rdsk/c?t?d?


vgextend /dev/vg00 /dev/dsk/c1t0d0 # same thing
lvextend -m 1 /dev/vg00/lvol1 /dev/dsk/c1t0d0

# real disk. repeat for other lvols

lvlnboot -r /dev/vg00/lvol3 # root fs /
lvlnboot -s /dev/vg00/lvol2 #swap
lvlnboot -d /dev/vg00/lvol2 #swap/dump
lvlnboot -b /dev/vg00/lvol1
lvlnboot -R
lvlnboot -v
setboot
setboot -a 52.1.0 # second disk

You have little choice at this point but to put the orginal boot disk back in, and re-mirror it using the procedure and tests above.

Thanks Steven,

I concern was different....For ex:-(say c1t0d0 with mirror disk c1t2d0 with hp-ux11.11. I unmirrored OS disk ... and removed unmirror(c1t2do) disk from vg00. So as a result I have hp-ux 11.11 on c1t0d0 without mirror. No problem when system is booting from c1t0d0 (hp-ux 11.11)...


Now I restored ignite of hp-ux 11.00 (from differnet H/W) mentioning cloning H/W=true in ignite restoration process...on c1t2d0 disk. (So I have hpux11.11 on c1t0d0 and hpux 11.00 on c1t2d0). Once finished restoration, system is going to reboot after building kernel. Here system is not came up . but giving the above error...

Could any one please help to sort out the problem?

=================

Was image belongs to different H/W? Do you what kind of model was it belong to? Also, was image checked ever before? Feel that Ignite image corrupted and may not restore even on the original hardware.

[Gouranga Maiti]

Yes I am installing on other H/W.
But model of both system same 9000/800/L2000-36.

The ignite backup is also ok... because I installed earlier on same machine without any issue using same ignite.
