VMware View Composer has a maximum of 8 Hosts Per Cluster

Last week we added some Cisco UCS Hosts to our Vmware environment with out any real problems. Then today using Vmware View tried to compose some additional View VMs.

Instead of provisioning them I instead get the following error.


VMware.Sim.Fault.TooManyHostsInComputeResourceFault: Resource pool MoId = resgroup-133, cluster MoId = domain-c132, numHosts = 16, maxHosts = 8

Looking into the VMware.Sim.Fault.TooManyHostsInComputeResourceFault I find a Vmware forum post stating that "The limitation is around Composer and you can only  have a maximum of 8 Hosts per Cluster".  Hoping this was simply a mistake or changeable I looked into it further. It seems to be unchangeable rule that you have to deal with.

From this Vmware Admin Guide they state that the cluster must have 8 or fewer hosts.

NOTE   Only clusters of 8 hosts or fewer are supported and shown.
