Unhappy Help urgent : vio server - add extral disk on virtual lpar


Hi,
I define 2 new LV on the vio server and run a cfgmgr on the partition and see my 2 new hdisk (hdisk6 and hdisk7).
I extend my vg vg000 (on the partition) and add the 2 hdisks.
I had a filesystem on the vg000 and when I added the disk I would like to increase the filesystem. But I cannot do a mirrorvg of vg000, I had an error message saying it cannot perform the mirror there is no lv ... but there is a lv and filesystem mounted ...
I tried command on line and by smitty but the same message.

I did a test to see if I stop one vio if my vg will be still available:
On the partition I have rootvg, vg000 and vg001
When I stopped one vio server:
I can see rootvg, vg001 but vg000 I had the following message:
# lsvg -l vg000
0516-034 : Failed to open VG special file. Probable causeis the VG was forced offline. Execute the varyoffvg and varyonvgcomma

So now I am sure that I need to do something after adding the new disk, redo the mirror but I dopn't how to do it as it was failed...

# lsvg -p rootvg
rootvg:
PV_NAME PV STATE TOTAL PPs FREE PPs FREE DISTRIBUTION
hdisk0 active 575 331 101..00..00..115..115
hdisk3 missing 575 575 115..115..115..115..115

lsvg -p vg001
vg001:
PV_NAME PV STATE TOTAL PPs FREE PPs FREE DISTRIBUTION
hdisk2 active 31 25 07..00..06..06..06
hdisk5 active 31 25 07..00..06..06..06

# lsvg -p vg000
0516-034 : Failed to open VG special file. Probable causeis the VG was forced offline. Execute the varyoffvg and varyonvgcommands to bring the VG online.

So if you have any idea what to do when you add extra disks on a vg already defined to make sure that the mirroring is good if we lose one vio server we still have the vg well defined on the partition?
Thanks in advance

with the vio the game is the same as with standard disk.
as long as disks will be seen as "missing" a lot of bad things will occur.
So, first make all disks available (starting all the vio's for instance) and reboot your client partition.
From your text I don't clearly understand which disks belong to vg00, but clearly it seems that you have no disks at the moment you issue the lsvg command, or something is wrong on one disk. How does "lspv" behave ?

Unfortunately, there is no smart error ! all errors are stupid.
Our goal here is to help you recover from such kind of error, whenever it's possible.
