Detailed Description

Parameters

Name	Type	Description	Required?	Pipeline Input	Default Value
Configuration	VsanClusterConfiguration[]	Specifies the configurations that you want to modify. This parameter supports OBN based on the names of the associated cluster. This parameter also directly accepts objects of type Cluster by silently converting them to the configuration object through ArgumentTransformationAttribute.	true	True (ByValue)
AddSilentHealthCheck	String[]	Specifies the health checks list you want to add to the silent list.	false	False
AllowReducedRedundancy	Boolean	Allows reduced redundancy state. This optional parameter is applicable to specific vSAN cluster reconfigure operations that need to migrate data across cluster for changing vSAN disk format. When specified, it might make the process move lesser data in order to ensure storage object accessibility, and some objects will be kept at reduced redundancy state, which means at a higher risk in case of a hardware failure during the migration process. This is applicable to the SpaceEfficiencyEnabled parameter only. The default value is False.	false	False
Confirm	SwitchParameter	If the value is $true, indicates that the cmdlet asks for confirmation before running. If the value is $false, the cmdlet runs without asking for user confirmation.	false	False
CustomizedSwapObjectEnabled	Boolean	Enables and disables customer's fully control the policy 'proportionalCapacity' for swap object The default value is False.	false	False
DefaultIncomingChapSecret	SecureString	Specifies the default CHAP secret for iSCSI targets on this cluster. Applicable when the authentication type is Chap or MutualChap.	false	False

It is mandatory if IscsiTargetServiceEnabled is specified as $true. This parameter accepts an object of type HostVMKernelVirtualNic by silently converting it to the string name by using ArgumentTransformationAttribute.	false	False
DefaultIscsiTargetAuthenticationType	VsanIscsiTargetAuthenticationType	Specifies the default authentication type for the vSAN iSCSI targets in this cluster.	false	False
DefaultIscsiTcpPort	Int32	Specifies the default network port for the iSCSI targets. This can be overridden per target. If not provided, the default port 3260 is used. The server automatically opens the firewall for the specified port.	false	False

DefaultOutgoingChapUser	String	Specifies the default CHAP user name you want to attach to the initiator. This is applicable when the authentication type is MutualChap.	false	False
GuestTrimUnmap	Boolean	Specifies the TRIM/UNMAP for the respective ATA and SCSI protocols. If this setting is switched from disabled to enabled for any unmap request to vSAN datastore from powered on virtual machines, this will take effect and succeed immediately. If it is switched from enabled to disabled dynamically, running virtual machines residing on this vSAN datastore will understand this change until virtual machine rebooting happens. The default value is False.	false	False
HealthCheckIntervalMinutes	Int32	Specifies the health check interval in minutes. If the value of this parameter is non-zero, then health check is enabled on the cluster and health check frequency is set to the specified value. If the value of the parameter is zero, then health check is disabled on the cluster. The accepted values are from 15 minutes to one day (1440 minutes).	false	False
IscsiTargetServiceEnabled	Boolean	Enables or disables the iSCSI target service on a vSAN cluster.	false	False
LargeClusterSupported	Boolean	Enables and disables large cluster supported. If this option is changed before vSAN enabled, it can be applied at host side immediatelyl.

ProactiveRebalanceEnabled	Boolean	Specifies whether proactive rebalance is enabled. If the value is set to True, rebalance data movement starts when the following requirements are met within the vSAN cluster: 1. Current disk fullness - lowest disk fullness > proactive threshold. 2. Current disk fullness > mean disk fulless within cluster. The default value is False.	false	False

When you enable the iSCSI target service, vSAN creates a home object that stores metadata for the iSCSI target service. The storage policy for the home object should have a number of failures to tolerate.	false	False
StretchedClusterEnabled	Boolean	Enables or disables stretched cluster configuration.	false	False
VsanBaselinePreference	VsanBaselinePreferenceType	Specifies the baseline preference policy for the current vSAN cluster.	false	False
