Known issues

Some VMAN and SQL server upgrade scenarios can cause Database configuration failed error during VMAN upgrade
Issue: When upgrading VMAN, a "Database configuration failed" error may occur for some VMAN and SQL server upgrade scenarios.

 

The "Top 10 VMs by Used Space" and "Top 10 VMs by Allocated Space" widgets incorrectly show some values as 0 instead of N/A
Issue: Instead of showing values as N/A, some widgets show some values incorrectly as 0.

 

Storage Usage of This Guest for VMs is always zero when VM is under standalone ESXi host
Issue: In the Virtual Machine Details widget, for VMs hosted on a standalone ESXi host, Storage Usage of This Guest for VMs is always shown as zero.

 

Adding a vCenter that has two or more ESXi hosts with the same hostname only adds one ESXi host to the Orion Platform
Issue: Adding two or more ESXi hosts with the same hostname only adds one ESXi host to the Orion Platform.

 

Nutanix devices are not supported for Chargeback reports
Issue: Chargeback reports cannot be generated for Nutanix clusters or AHV hosts.

 

German language environments are not supported for Chargeback reports
Issue: Chargeback reports cannot be generated for VMAN instances in a German language environment.

 

Incorrect AppStack data for vCenters
Issue: AppStack data for a vCenter may in some cases be displayed incorrectly when the vCenter is deployed as a virtual machine under an ESXi host that is monitored by the same vCenter.

 

Account limitations may not work with VIM/VMAN groups
Issue: Account limitations may not work correctly in some cases with VIM/VMAN groups.

 

Custom charts show irrelevant host
Issue: Custom charts for VMAN clusters may sometimes show an irrelevant host in the chart legend.

 

Gray vCenter status and System.OutOfMemoryException in logs
Issue: In some cases, polling a vCenter may fail, resulting in a gray vCenter status. Recorded in VMAN logs is the message: "Failed to allocate a managed memory buffer of 1073741824 bytes. The amount of available memory may be low. System.OutOfMemoryException: Exception of type 'System.OutOfMemoryException' was thrown".

 

Performance issues with a single shared datastore
Issue: A single datastore being shared among many vCenters and/or hosts can cause performance issues during polling.

 

Predicted Datastore Space Depletion widget, disappearing datastores
Issue: Datastores sometimes randomly disappear from the Predicted Datastore Space Depletion widget

 

VMAN polling engines performance issues after Database maintenance
Issue: Database maintenance can in some cases cause performance issues for VMAN polling engines.

 

Incorrect status shown for vCenter
Issue: If VMAN's polling process has failed for any reason, the last known status for a vCenter is shown in VMAN. This could result in a normal, green status being shown for a vCenter when it shouldn't.
