If you have desktops deployed via Horizon View 6.x/7.x Instant Clones technology it can get very difficult to collect the Horizon View Agent logs from the desktop VM for troubleshooting/analysis purposes. The moment the end-user logs-off from the desktop it gets into the Status = Disconnected –> Deleting.
vCenter Task for log-in and log-off of the desktop
vCenter Task for Deleting –> Customizing –> Available
The above operations happen very quickly. Suppose in our scenario the desktop was failing on the Status=Customizing (View Administrator). The desktops status would change into the Error state and after couple of seconds get into delete will remain in a loop until the desktop becomes available. This is by design as the Instant Clone is trying to re-create the desktop There was no way to capture the logs for analysis or troubleshooting.
Resolution:Now you can disable the recovery of the Instant Clone desktop VM if they are in the Status=Error (Strictly for troubleshooting purposes). This setting can be enabled at Desktop Pool Level
Desktop Pool Setting (disable autorecovery):
- Open the Horizon View ADAM – (DC=vdi,dc=vmware,dc=int)
- Go to OU=Server Groups – on you right select OU=DesktopPoolName (this is the name of your desktop pool)
- Search for pae-RecoveryDisabled and click Edit
- Enter Value =1 and click Add – OK
Now whenever your desktop within the Pool will be in Status=Error it will not delete the VM and keep it in the Error state for you to capture the logs and perform troubleshooting. Please revert the changes of this settings once you have finished analysis. I hope these steps would be helpful leave a comment down below
