Host addition fails

Solution

• Check the error message in the operation log to identify the cause. If the failure persists, check the following:

• Verify that the host information is entered correctly and that the host and the Management Node can communicate bidirectionally.

• Verify that the operating system version, CPU model, type, and architecture of the host match those of all other hosts in the Cluster.

• Verify that CPU hardware virtualization is enabled on the host.

  Run egrep "vmx|svm" /proc/cpuinfo to verify whether CPU hardware virtualization is enabled. If the command produces output, hardware virtualization is enabled.

• Verify that the host NIC matches the NIC used by the Distributed Switch attached to the Cluster.

• Verify that the host can access the Data Storage.

  If distributed storage is deployed separately from Compute Nodes, you must add the distributed storage node as a gateway server role on the host; otherwise, the host cannot access storage.

• Verify that no manually installed software packages on the host are causing conflicts.
