We have vcenter 6.7 u1 and nsx 6.4 this message shows in the overview in 'Networking and security'
plz help me to solve this error
Failed to get data for 'Host Preparation Status, Host Communication Channel Status' : Aggregate Count Widget LabelValueConfiguration_HostCommunicationChannelStatus has an invalid number null. Only numbers are allowed as fields for aggregate_count sub-type.
is it a day 1 issue ?
what is the status of NSX manager and VC connectivity ?
what is the version of Vcenter ?
What is the error you are seeing under installation tab ?
As per NSX 6.4.4 release note:
Minimum Supported: 6.7
Recommended: 6.7 Update 1
When a host is deleted from the inventory without performing NSX Host unprep, entries related to this host are not cleaned up from the fabric table.
This causes the above symptom.
We also received this issue when removing several hosts and clusters through the SDDC manager (we're running VCF 3.7.1).
Edit/update: Unfortunately we had to create an SR to resolve this issue. It was quickly fixed, they confirmed this is not something that can be done without GSS (it involves editing database entries).
