Subject [jira] [Commented] (CLOUDSTACK-7360) [vmware] Add host to existing cluster fails if the cluster is using Nexus 1000v as backend for atleast one traffic type.

Sateesh Chodapuneedi commented on CLOUDSTACK-7360:
--------------------------------------------------

Following procedure to add host doesn't work if the cluster is using Nexus 1000v as backend
for atleast one traffic type.
1) Add ESXi host to a VMware cluster in vCenter
2) Add host using CCP UI.
Side effect of the failure is the existing cluster's record in database is being deleted as
a result of handling discovery failure while adding host. This should be avoided such that
a host add attempt failure should not affect the existing cluster.
While adding a VMware cluster (which is using Nexus 1000v as network backend) CCP does validation
of Nexus VSM's IP address & it's credentials to be used by CCP later for virtual network
orchestration. addCluster API does supply meta data related to VSM which is available for
validation during discovery of cluster. But in case of addHost the work flow doesn't supply
the VSM metadata. This missing information is resulting in failure while validating during
discovery process.
We need 2 changes,
1) Ensure host discovery / validation failure while adding host should not affect existing
cluster in any way.
2) Skip validation of VSM metadata during host addition to cluster. It is admin's responsibility
to add ESXi host to the cluster and the associated VSM correctly before trying to add it using
CCP UI.

> Steps to reproduce:
> 1) Before creating zone, set global params vmware.use.nexus.vswitch & vmware.use.dvswitch
is to "true".
> 2) Complete zone wizard
> 3) Using vCenter add ESXi host to a cluster, which is already being managed by CCP
> 4) Using CCP UI add the same host to that cluster - This fails
