Troubleshooting 81
Could not activate compute nodes
Symptom
Could not activate compute nodes.
Explanation
The installer is trying to add any hosts in the compute cluster as activated nodes in CloudSystem.
Potential problems could occur if vCenter is not registered or it fails to find an OVA image.
Action
Perform one or both of the following actions:
•
Follow the steps below to activate the compute nodes.
•
Refer to
HPE Helion CloudSystem 9.0 Administrator Guide
located on the Hewlett Packard
Enterprise website (
http://www.hpe.com/info/CloudSystem/docs
1.
Launch vSphere, and verify the following:
o
that each compute host is alive and not in maintenance mode.
o
that the Comp-CloudData-Trunk distributed switch has been created and uplinks assigned for
each compute host.
2.
In the CS9 Operations Console, select Menu > Compute > Compute Nodes.
3.
For each compute cluster, perform the following:
a.
Select a cluster (e.g. sHosts01) by clicking on the circled checkmark next to the cluster name.
b.
Click the Activate button.
c.
Select Distributed vSwitch Name option and supply the value Comp-CloudData-Trunk.
d.
Select the Queue for Activation button.
e.
Select Complete Activations.
f.
Click Confirm Activations.
An ovsvapp-<compute_host> VM instance is created for each compute host. This step can take
several minutes and will depend on the number of compute nodes.
If the activation fails, use the following troubleshooting options:
—
Sometimes the activation has completed but may show a RED status. Try refreshing the
browser and observe whether it changes to GREEN.
—
Verify that enough DCM IP addresses are allocated.
—
If any of the compute hosts are in maintenance mode or the management appliance (ma1)
cannot maintain a network connection to a compute host, the ovsvapp deploy will fail.
—
Use the Menu General Logging Dashboard to help diagnose any problems.

Could not create Tenant VLAN Segment Ranges
Symptom
Could not create tenant VLAN segment ranges.
Explanation
The installer is attempting to create segment ranges in CloudSystem for VLANs listed in the Tenant VLAN
section of the user interface. Potential problems could occur if the OpenStack services are not all running.
