vSphere HA Virtual Machine Component Protection Service detects and reacts to storage failures that do not necessarily cause a virtual machine to go down, but may impact the health or QoS of the virtual machine.
All fields are defined as optional. In case of a reconfiguration, fields left unset are not changed.
Properties
Name | Type | Description |
---|---|---|
enableAPDTimeoutForHosts* | xsd:boolean |
This property indicates if APD timeout will be enabled for all the hosts
in the cluster when vSphere HA is configured. The details of APD timeout are
described in HostMountInfoInaccessibleReason.
If vmComponentProtecting is disabled, the property will be ignored. Otherwise, for each host in the cluster, APD timeout will be enabled. Note that no change will be made for a host if it already had APD timeout enabled. This property is meaningful only for cluster setting. It is ignored if specified at VM level. The default value is false if not specified.
Note that this property is not persisted by vSphere backend. It does not impact any cluster
reconfiguration or host operation (such as adding a host to a cluster) that might happen later.
|
vmReactionOnAPDCleared* | xsd:string |
Action taken by VM Component Protection service for a powered on VM when APD
condition clears after APD timeout.
This property is meaningful only when vSphere HA is turned on. Valid values are
specified by VmReactionOnAPDCleared. The default value is
VmReactionOnAPDCleared#none for cluster setting and
VmReactionOnAPDCleared#useClusterDefault for per-VM setting.
|
vmStorageProtectionForAPD* | xsd:string |
VM storage protection setting for storage failures categorized as All Paths
Down (APD). APD is a condition where a storage has become inaccessible
for unknown reasons. It only indicates loss of connectivity and does not indicate
storage device failure or LUN removal (Permenant Device Loss or PDL). The details
of APD and PDL are described in HostMountInfoInaccessibleReason.
This property is meaningful only when vSphere HA is turned on. Valid values are specified by StorageVmReaction. The default value is StorageVmReaction#disabled for cluster setting and StorageVmReaction#clusterDefault for per-VM setting. When an APD condition happens and the host begins timing out I/Os (@link vim.host.MountInfo.InaccessibleReason#AllPathsDown_Timeout}, VM Component Protection service will react based on the specific value of this property:
|
vmStorageProtectionForPDL* | xsd:string |
VM storage protection setting for storage failures categorized as Permenant Device
Loss (PDL). PDL indicates storage device failure or LUN removal. In case of PDL,
the failed datastore or device is unlikely to recover. The details of PDL are
described in HostMountInfoInaccessibleReason.
This property is meaningful only when vSphere HA is turned on. Valid values are StorageVmReaction#disabled, StorageVmReaction#warning, StorageVmReaction#restartAggressive and StorageVmReaction#clusterDefault. The default value is StorageVmReaction#disabled for cluster setting and StorageVmReaction#clusterDefault for per-VM setting.
When set to StorageVmReaction#restartAggressive, VM Component Protection service
will immediately terminate the VMs impacted by PDL and will attempt to restart the VMs
with best effort. When set to the other values, the behavior is the same as described for
vmStorageProtectionForAPD.
|
vmTerminateDelayForAPDSec* | xsd:int |
The time interval after an APD timeout has been declared and before VM Component
Protection service will terminate the VM. The value only applies if
vmStorageProtectionForAPD is set to StorageVmReaction#restartConservative or
StorageVmReaction#restartAggressive.
The default value is 180 seconds if not specified. To use cluster setting for a VM override,
set to -1 in per-VM setting.
