## Managed Object Description

This managed object type provides a comprehensive way to manage vSAN cluster configuration in below areas:

- Enable or disable vSAN
- Enable or disable Autoclaim mode for disk group
- Enable or disable data efficiency feature
- Configure vSAN iSCSI target feature
- Manage disk groups
- Manage fault domains
- Retrieve vSAN generic configuration
- Retrieve data efficiency configuration

In this class, ReconfigureEx enhances the legacy API ReconfigureComputeResource_Task. Legacy API ReconfigureComputeResource_Task is deprecated.
The ManagedEntity can be accessed with MOID of 'vsan-cluster-config-system', through vSAN service at vCenter server side.

# RunLifecycleCheck(runLifecycleCheck)

Run checks for lifecycle operations on a given vSAN cluster. The specification indicates the lifecycle operation for which checks will be performed. The result contains an overall status of the checks, a list of the checks run, and vSAN cluster configurations details related to the checks. The overall status of the checks in the result represents the highest severity status of all the results of the individual checks. For example, if all tests pass, the highest severity status is green. If a test results in yellow status and another in red status, the overall status will be red. The list of checks contains a description of the check, its result status and in case of failure, a localized error message. The vSAN cluster configuration details contains information like witness host and fault domains information for stretched clusters, or no witness host information to indicate single-site cluster.

# VsanClusterGetConfig(getConfigInfoEx)

Get configInfoEx for a vSAN cluster
We can get vSAN configuration information through this method. Currently users can only get generic cluster configuration and data efficiency configuration through this API.
This API cannot retrieve fault domain configuration and disk group configuration. Disk group configuration can be retrieved through QueryDiskMappings. Fault domain configuration can be retrieved through Config.

# VsanClusterReconfig(reconfigureEx)

Reconfigure a vSAN cluster. This method is used to set vSAN specific configuration, the method can be used to modify all vSAN related configuration. From vSAN 6.2, this API is the replacement of ReconfigureComputeResource_Task in order to support more configurations such as deduplication and compression, fault domain, disk mapping configuration in the cluster. The legacy API ReconfigureComputeResource_Task is deprecated because new API provide everything that legacy API has. To modify generic vSAN cluster setting such as vSAN enablement and autoclaim enablement, vsanClusterConfig needs to be setup. To modify vSAN cluster specific features such as deduplication and compression enablement, dataEfficiencyConfig needs to be setup. Currently for vSAN 6.2, deduplication and and compression need to be enable/disable together. To enable/disable deduplication and compression on a vSAN cluster, disk convert process (PerformVsanUpgradeEx for description about disk convert process) will be invoked. This is only supported for all-flash disk groups. To modify vSAN cluster fault domain configuration, faultDomainsSpec needs to be setup. To modify vSAN cluster disk groups reconfiguration, diskMappingSpec needs to be setup. To modify vSAN iSCSI target service configuration, vim.vsan.ReconfigSpecs#iscsiSpec needs to be setup.

Reconfiguring vSAN cluster requires Host.Inventory.EditCluster privilege on the cluster, extra privileges may be required depending on what is being changed:

- Cryptographer.ManageEncryptionPolicy and Cryptographer.ManageKeys if changing data encryption configuration.

# VsanEncryptedClusterRekey_Task(rekeyEncryptedCluster)

Regenerate the key(s) used by vSAN encryption for the given cluster. When the key(s) used for vSAN encryption is compromised, this API can be used to renew the key(s). As described in VsanHostEncryptionInfo, vSAN uses Key Encryption Key (KEK) to wrap the Data Encryption Key (DEK). Generally a user will only need to renew the KEK and use new KEK to rewrap the DEK, when KEK is compromised, or on regular basis. This is referred to as "shallow rekey". If user suspects that DEK is also compromised, both KEK and DEK will be renewed. Correspondingly this is called "deep rekey". And as a consequence of DEK change, the data on vSAN datastore will be re-encrypted with the new DEK, so this will be a slow process.
This API does not support switching to a different KMS cluster. When there is a need to switch to a different KMS cluster, call vim.cluster.VsanVcClusterConfigSystem#VsanClusterReconfig and specify a different KMS cluster in the configuration kmsProviderId.

To run either shallow rekey or deep rekey for an encrypted vSAN cluster, both Cryptographer.ManageKeys privilege and Host.Inventory.EditCluster privilege are required on the cluster. If it is a shallow rekey, alternatively, caller with Vsan.Cluster.ShallowRekey privilege on the cluster will also be allowed.

# VsanQueryClusterDrsStats(queryClusterDrsStats)

To support integration between vSAN and DRS, we are expected to report runtime stats of vSAN member hosts and VMs locate in specified vSAN cluster from storage perspective. Per request from DRS service, below stats are requested:

- 1. capacity contributed to vSAN datastore per host;
- 2. capacity usage to vSAN datastore per host;
- 3. total size per vSAN VM;
- 4. valid data percentage on every host per vSAN VM;

This API is used to retrieve runtime stats requested by DRS.

# VsanValidateConfigSpec(validateConfigSpec)
