Using BOSH Resurrector on vSphere
Page last updated:
The BOSH Resurrector increases Pivotal Application Service (PAS) availability in the following ways:
- Reacts to hardware failure and network disruptions by restarting virtual machines on active, stable hosts
- Detects operating system failures by continuously monitoring virtual machines and restarting them as required
- Continuously monitors the BOSH Agent running on each virtual machine and restarts the VMs as required
The BOSH Resurrector continuously monitors the status of all virtual machines in an PAS deployment. The Resurrector also monitors the BOSH Agent on each VM. If either the VM or the BOSH Agent fail, the Resurrector restarts the virtual machine on another active host.
The following limitations apply to using the BOSH Resurrector:
- The Resurrector does not monitor or protect the Ops Manager VM or the BOSH Director VM.
- The Resurrector might not be able to resolve issues caused by the loss of an entire host.
- The Resurrector does not monitor or protect data storage.
For increased reliability, in addition to using BOSH Resurrector, Pivotal recommends that you use vSphere High Availability to protect all of the VMs in your deployment, and that you use a highly-available storage solution.
Follow the steps below to enable vSphere High Availability:
Launch the vSphere Management Console.
Right-click the cluster that contains the Pivotal Cloud Foundry (PCF) deployment and select Edit Settings.
Check the Turn on vSphere High Availability checkbox.
Click OK to enable vSphere High Availability on the cluster.
To enable the BOSH Resurrector:
Log into the Ops Manager web interface.
On the Product Dashboard, select BOSH Director.
In the left navigation menu, select Director Config.
Check Enable VM Resurrector Plugin and click Save.
