Cross device link. The disk is not a LVM disk.
LVM: VG 64 0x000000: Quorum check failed!

Try booting vpar in maintenance mode using vparboot or vparload using -o "-lm" and try repairing the LVM structure.

Else try booting after disabling quorum using -o "-lq".

Will this affect other vpars in the npar?

Hi,

If you use the correct options - no.

to boot a vpar in Single user mode.
- from Vpar Monitor prompt,

Mention the correct vpar name after -p option
# vparload -p vPar3 -o "-is"
- from shell prompt of other Vpars,

# vparboot -p vPar3 -o "-is"
or
# vparboot -p vPar3 -o "-lq"
vparstatus will show the boot flags

Boot the virtual partition called Oslo:

vparboot -p Oslo Boot the virtual partition Bergen specifying an alternate kernel:

vparboot -p Bergen -b /stand/vmunix_debug

Rgds.

Now i have tried the command

vparload -p misapp3 -o "-lm"

Now the error is

Load of 1/0/1/1/1.0.0.0.0.0 failed.

what about the other options?? Have you tries quorum disable or single user mode ??

Try booting from the alternate disk if you had mirroring in place.

>LVM : Failure in attaching PV (1/0/13/1/1.0.0) to the root volume group.
Cross device link. The disk is not a LVM disk.
LVM: VG 64 0x000000: Quorum check failed!
LVM : Activation of root volume group failed
Quorum not present, or some physical volume(s) are missing

>boot /stand/vmunix -lm ; pvck -y /dev/rdsk/

-The system already tried pvck command and it examines and repairs LVM data structures on a raw disk (pv-path) in a volume

-Did you check the disks.

vparboot -p misapp3 -o "-lq"
vparboot -p misapp3

To set the primary boot path:

If you have a mirror disk, try setting the boot path and boot again

misapp1111111# vparcreate -p misapp3 -a io:0.8.0.0.5.0:BOOT

Re: vpar Boot issue

Rasheed Tamton — Wed, 14 May 2008 07:12:08 GMT

Try from the other vpar the below cmd:

misapp1111111# vparstatus -p misapp3 -v

Re: vpar Boot issue

Azaru — Wed, 14 May 2008 07:17:28 GMT

Primary boot path not found.
Internal error in setting up vPars variables.
"misapp3" load failed.

Now the error is coming like this.

Looks like there is no EFI path mapping. In that case you might have to use vparefiutil -u

man vparefiutil

How did it happen in the first case, did you add another disk as mirror

the only reason why u re not able to process the boot is because the quorum is not reached so neither u modify definitely your config via a vparmodify adding in boot options -lq neither u do it only at boot time but this kind of modification should remain
u should have sometinh like in your vparstatus
Dyn,Auto,Asr /stand/vmunix -lq
