Virtual Machines have a missing Host alert when it does have a Host

Title

Summary

This VM does not have a host message may appear, even though the VM has been linked to a host.

Symptoms

Under the 'All Inventory' page, you may encounter the following message appear when hovering over a red bubble, while the VM is linked to a Host:

This VM does not have a host

Cause

This only occurs because the system only re-evaluates alerts on Inventory Devices under three conditions:

When a Device's serial number changes
When a Device's status transitions between Active, Ignored or Awaiting Inventory
When a Device is linked/unlinked from an Asset

This means that it is possible for a Virtual Machine to be linked to a Host but still has the alert displayed on versions prior to FlexNet Manager Suite 2015 R2 SP4.

Resolution

This was tracked under FNMS-28311 and has been fixed in FlexNet Manager Suite 2015 R2 SP4.

Workaround

The attached fix is a SQL script that can be run in two steps against your FNMSCompliance/FNMP Database for the versions of FlexNet Manager Suite 2015 R2 till FlexNet Manager Suite 2015 R2 SP3:

Step #1: This script will create a new trigger as a permanent fix, which will refresh the Alerts whenever any VM or Host relationship changes
Step #2: Since the trigger only runs when something changes, step #2 can be used as a one-time basis to refresh the Alerts for all of your Virtual Machines and Hosts that are in Active status.
