<p class="MsoNormal">I remember this from older versions of ESxi “VMWare ESXi, the second logical volume is automatically imported unaligned” Is this still true with ESXi 5.5 and CUCM 10x ? I’ve never actually seen where the ESXi install creates the second
datastore that the VMs are kept on. I always have to do it manually in vSphere client.<o:p></o:p></p>
