Hi Cer,

Thanks a lot for getting back on this ...

We have setup where we need to move the standalones to LPARs and in this case we need to make sure that we have cleared the LUN reservation on the source server and then later import the vgs which will be on target.

So was jst curious to knw what wud be the case if LUN reserveration is not cleared.

Regards,
nivas
