Yes. I think the server had swap disks. I just want to increase the size of the V-disks. I increased them as far as VM is concerned.

Anyway -- your swap disks are probably defined in /etc/fstab - so check there to ensure they are all mounted as swap. If you've added any disks, add the appropriate line to the fstab. To see what's in use: swapon -s Hope that helps..
