Failed host recovery

VMware hypervisor
If you do not use the VMware VirtualCenter High Availability (HA) solution, then use the failed host recovery
feature.
The failed host recovery feature enables you to recover a failed VMware ESX Server host and leverage the
ability of HP SIM to detect hardware failures.
In a setup where both the failed host recovery feature and VMware VirtualCenter HA or VMware Distributed
Resource Scheduler (DRS) are configured, the results might be unpredictable because both management
tools try to control the same resource.
Do not configure both the failed host recovery feature and the VMware HA or VMware DRS solution for the
same VMware ESX hosts.
If the virtual machine being moved is part of the VirtualCenter cluster, then a warning message appears.
When a failed host recovery process is being performed for virtual machines failing over to the alternate
hosts, the moved virtual machines might appear as Orphaned in the VirtualCenter. If this occurs, delete the
orphaned nodes from VirtualCenter.
HP integrated Citrix XenServer
The failed host recovery feature enables you to recover a failed Citrix XenServer host and leverage the ability
of HP SIM to detect hardware failures.
In a setup where both the failed host recovery feature and Citrix XenServer HA is configured, the results
might be unpredictable because both management tools try to control the same resource.
Do not configure both the failed host recovery feature and the Citrix XenServer HA for the same Citrix
XenServer hosts.

Setting up the recovery feature

1. Create a CriticalVmHost collection based on the system health parameters.
2. Set your virtual machines so that you have defined alternate hosts appropriately.
3. Schedule the recovery of failed hosts based on the collection and events.
