Detailed Description

This cmdlet starts the update of all vSAN disks of a cluster to the latest vSAN disk format version supported by the cluster. After the update finishes successfully, all vSAN disks in the cluster use the latest disk format version supported by the cluster. The cmdlet returns a task object that you can wait upon and query for progress.

Parameters

Name | Type | Description | Required? | Pipeline Input | Default Value
--- | --- | --- | --- | --- | ---
Cluster | Cluster[] | Specifies the cluster for which you want to update all vSAN disks. | true | true (ByValue)
AllowReducedRedundancy | Boolean | This optional parameter is applicable to specific vSAN cluster reconfigure operations that need to migrate data for changing the vSAN disk format across the cluster. When specified, the process might move less data to ensure storage object accessibility, and some objects might be kept at "reduced redundancy" state, which means at a higher risk in case of a hardware failure during the migration process. 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
Server | VIServer[] | Specifies the vCenter Server systems on which you want to run the cmdlet. If no value is given to this parameter, the command runs on the default servers. For more information about default servers, see the description of Connect-VIServer. | false | false
WhatIf | SwitchParameter | Indicates that the cmdlet is run only to display the changes that would be made and actually no objects are modified. | false | false

Return Type

Null
