Detailed Description

This cmdlet modifies the properties of the specified datastore. You can use the following characters in a path, but not in a datastore name: slash (/), backslash (\), and percent (%).

Parameters

Name | Type | Description | Required? | Pipeline Input | Default Value
--- | --- | --- | --- | --- | ---
Datastore | Datastore[] | Specifies the datastore whose properties you want to change. | true | true (ByValue)
Name | String | Specifies a new name for the datastore. Do not use slash (/), backslash (\), and percent (%) characters in datastore names. | 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
CongestionThresholdMillisecond | Int32 | Specifies the latency period beyond which the storage array is considered congested. The range of this value is between 10 to 100 milliseconds. | false | false
EvacuateAutomatically | SwitchParameter | Specifies whether you want to automatically migrate all virtual machines to another datastore if the value of MaintenanceMode is $true. When the Storage DRS automation level is set to Fully Automated, you do not need to specify the EvacuateAutomatically parameter because Storage DRS will migrate all virtual machines automatically. If EvacuateAutomatically is specified, the SDRS placement and migration recommendations are automatically applied. If SDRS generates cluster DRS faults, an error report is displayed and the operation is cancelled. The report contains information about each datastore cluster DRS fault. If EvacuateAutomatically is not specified, an error report is displayed and the operation is cancelled. The error report contains information about each SDRS recommendation. If SDRS generates cluster DRS faults, an error report is displayed and the operation is cancelled. The error report contains information about each fault. If EvacuateAutomatically is explicitly set to false, the cmdlet blocks execution without displaying an error message. If SDRS generates datastore cluster DRS faults, the cmdlet stops responding and an error report is displayed. The report contains information about each cluster DRS fault. | false | false
MaintenanceMode | Boolean | Specifies whether you want to put the datastore in maintenance mode. The operation completes when no virtual machines are present and no provisioning processes are running on the datastore. | true | false
RunAsync | SwitchParameter | Indicates that the command returns immediately without waiting for the task to complete. In this mode, the output of the cmdlet is a Task object. For more information about the RunAsync parameter run "help About_RunAsync" in the VMware PowerCLI console. | 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
StorageIOControlEnabled | Boolean | Indicates whether you want to enable the IO control. | 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

Zero or more modified Datastore objects

Notes

Examples

-------------- Example 1 --------------

    Get-Datastore -Name Datastore1 | Set-Datastore -Name Datastore2

Renames the Datastore1 datastore to Datastore2.

-------------- Example 2 --------------

    Set-Datastore $datastore1, $datastore2 -StorageIOControlEnabled $true -CongestionThresholdMillisecond 80

Enables the Storage IO Control and set a congestion threshold of 80 milliseconds for the specified datastores.

-------------- Example 3 --------------

    Get-Datastore -Name 'MyDatastore1' | Set-Datastore -MaintenanceMode $true -EvacuateAutomatically

Puts the MyDatastore1 datastore in maintenance mode and specifies that all virtual machines on the datastore will be automatically migrated to another datastore.
