Detailed Description

The Set-StoragePool cmdlet modifies the properties of the specified storage pool.

Parameters

-AsJob

Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to complete. The cmdlet immediately returns an object that represents the job and then displays the command prompt. You can continue to work in the session while the job completes. To manage the job, use the *-Job cmdlets. To get the job results, use the Receive-Job cmdlet. For more information about Windows PowerShell® background jobs, see about_Jobs.

-AutoWriteCacheSize<Boolean>

Indicates whether to set the size of the write-back cache to 1 GB for all types of storage spaces, which include simple, mirror, and parity, to create from the pool. If the number or size of the solid-state drives (SSDs) or journal disks in the storage pool is not sufficient and you specify a value of $True for this parameter, the cmdlet sets the write-back cache size to 0 for simple and mirror spaces, and to 32 MB for parity spaces.

-CimSession<CimSession[]>

-EnclosureAwareDefault<Boolean>

Specifies that the storage pool should use enclosure awareness by default when creating storage spaces.

To support deployments that require an added level of fault tolerance, Storage Spaces can associate each copy of data with a particular just-a-bunch-of-disk (JBOD) enclosure. This capability is known as enclosure awareness. With enclosure awareness, if one enclosure fails or goes offline, the data remains available in one or more alternate enclosures.

To use enclosure awareness, you must use JBODs that are certified for use with Storage Spaces and you must have a sufficient number of JBODs and disks to support the resiliency types of the storage spaces you create (generally you’ll need three or four JBODs). For a list of certified JBODs, see the Windows Server Catalog. For more information about enclosure awareness, see Storage Spaces Frequently Asked Questions.

-IsPowerProtected<Boolean>

Indicates whether the physical disks that belong to the storage pool have backup power systems, such as battery backup. If you specify a value of $True for this parameter, the storage pool does not perform flush operations, and the pool removes write-through attributes from commands.

-IsReadOnly<Boolean>

Sets the object to be read-only (IsReadOnly $true) or read-write (IsReadOnly $false). Note: If the object is set to read-only (IsReadOnly $true), the object must be set to read-write (IsReadOnly $false) before using this cmdlet to set the PartitionStyle parameter.

-RepairPolicy<RepairPolicy>

Specifies how the operating system proceeds with repairing virtual disks in the specified storage pool. The acceptable values for this parameter are: 
--Sequential Repair processes one allocation slab at a time. Specifying this value results in longer repair times, but smaller impact on I/O load.
--Parallel Repair processes as many allocation slabs as it can in parallel.  Specifying this value results in the shortest repair time, but significantly impacts I/O load.

-ResiliencySettingNameDefault<String>

-ThrottleLimit<Int32>

Specifies the maximum number of concurrent operations that can be established to run the cmdlet. If this parameter is omitted or a value of 0 is entered, then Windows PowerShell® calculates an optimum throttle limit for the cmdlet based on the number of CIM cmdlets that are running on the computer. The throttle limit applies only to the current cmdlet, not to the session or to the computer.

<CommonParameters>

This cmdlet supports the common parameters: -Verbose, -Debug, -ErrorAction, -ErrorVariable, -OutBuffer, and -OutVariable. For more information, see    about_CommonParameters.

Inputs

The input type is the type of the objects that you can pipe to the cmdlet.

Outputs

The output type is the type of the objects that the cmdlet emits.

  • None

Notes

  • The Microsoft.Management.Infrastructure.CimInstance object is a wrapper class that displays Windows Management Instrumentation (WMI) objects. The path after the pound sign (#) provides the namespace and class name for the underlying WMI object.

Examples

Example 1: Change the friendly name

This example changes the friendly name of StoragePool to StoragePool2.


PS C:\> Set-StoragePool -FriendlyName StoragePool -NewFriendlyName StoragePool2

Example 2: Make a read-only storage pool writeable

This example makes the storage pool named Storage Pool 1 writable when it is in a read-only state.


PS C:\> Set-StoragePool -FriendlyName "Storage Pool 1" -IsReadOnly $False

Example 3: Set the default resiliency and provisioning settings

This example makes any new virtual disks by default use the Mirror resiliency setting and thin provisioning.


PS C:\> Set-StoragePool -FriendlyName "Storage Pool 1" -ResiliencySettingsNameDefault Mirror -ProvisioningTypeDefault Thin
