A vSphere administrator needs to add more space to an existing 3-node Virtual SAN cluster. The
attempts to add the new host to the cluster as a contributing member have failed. However, it can
be added as a non-contributing member.
The host was previously used in a single host configuration. The administrator recently upgraded the
host from ESXi 5.1 to 5.5 prior to adding it to the cluster.
What is the reason for this failure?
A.
The only SSD disk in the new host was formatted with a VMFS datastore.
B.
The new host has a 10Gbps NIC while the rest of the cluster members have 1Gbps NICs.
C.
The RAID controller in the new host does not have enough cache for the Virtual SAN datastore.
D.
The new host’s VMFS datastores do not have sufficient capacity to be added as a contributing
member.
