DESCRIPTION
The Set-StoragePool cmdlet modifies the properties of the specified storage pool.
PARAMETERS
-AutoWriteCacheSize []
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.
Required? false
Position? named
Default value none
Accept pipeline input? false
Accept wildcard characters? false
-CimSession []
Runs the cmdlet in a remote session or on a remote computer. Enter a computer name or a session object, such
as the output of a New-CimSession or Get-CimSession cmdlet. The default is the current session on the local
computer.
Required? false
Position? named
Default value none
Accept pipeline input? false
Accept wildcard characters? false
-ClearOnDeallocate []
Clears all blocks on the physical disks in the storage pool upon deallocation. Clearing all blocks is more
secure, but is much slower to deallocate.
Required? false
Position? named
Default value none
Accept pipeline input? false
Accept wildcard characters? false
-EnclosureAwareDefault []
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 Software-Defined Storage Design Considerations Guide.
Required? false
Position? named
Default value none
Accept pipeline input? false
Accept wildcard characters? false
-FaultDomainAwarenessDefault []
Specifies the default fault domain for new virtual disks created in this storage pool. The acceptable values
for this parameter are:
-- PhysicalDisk
-- StorageScaleUnit
-- StorageChassis
-- StorageEnclosure
-- StorageRack
The fault domain specifies at what level you want to be fault tolerant. For example, specify StorageScaleUnit
to store data copies on separate nodes of a Storage Spaces Direct cluster. This cmdlet refers to nodes of a
Storage Spaces Direct cluster as storage scale units because you can expand the scale of the cluster by adding
more nodes.
Required? false
Position? named
Default value none
Accept pipeline input? false
Accept wildcard characters? false
-FriendlyName
Specifies the friendly name of the storage pool on which you want to set attributes.
Required? true
Position? 1
Default value none
Accept pipeline input? True (ByPropertyName)
Accept wildcard characters? false
-IsPowerProtected []
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.
Required? false
Position? named
Default value none
Accept pipeline input? false
Accept wildcard characters? false
-IsReadOnly []
Sets the object to be read-only (IsReadOnly $true$true) or read-write (IsReadOnly $false$false). Note: If the
object is set to read-only (IsReadOnly $true$true), the object must be set to read-write (IsReadOnly
$false$false) before using this cmdlet to set the PartitionStyle parameter.
Required? false
Position? named
Default value none
Accept pipeline input? false
Accept wildcard characters? false
-MediaTypeDefault []
Specifies the default media type to use during virtual disk creation. The acceptable values for this parameter
are: HDD, SSD, and Unspecified.
Required? false
Position? named
Default value none
Accept pipeline input? false
Accept wildcard characters? false
-Name
Specifies the name of the storage pool on which you want to set attributes.
Required? true
Position? named
Default value none
Accept pipeline input? True (ByPropertyName)
Accept wildcard characters? false
-NewFriendlyName []
Specifies the new friendly name for the storage pool.
Required? false
Position? named
Default value none
Accept pipeline input? false
Accept wildcard characters? false
-OtherUsageDescription []
Specifies the OtherUsageDescription for the storage pool.
Required? false
Position? named
Default value none
Accept pipeline input? false
Accept wildcard characters? false
-ProvisioningTypeDefault []
Specifies the default type of provisioning to use for virtual disks created in the specified storage pool. The
acceptable values for this parameter are: Fixed or Thin.
Required? false
Position? named
Default value none
Accept pipeline input? false
Accept wildcard characters? false
-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.
Required? false
Position? named
Default value none
Accept pipeline input? false
Accept wildcard characters? false
-ResiliencySettingNameDefault []
Specifies the default resiliency setting (also known as storage layout) to use for virtual disks the created
in the specified storage pool. The supported resiliency settings vary by storage subsystem. Acceptable values
for the Windows Storage subsystem are Mirror, Parity, and Simple.
Required? false
Position? named
Default value none
Accept pipeline input? false
Accept wildcard characters? false
-RetireMissingPhysicalDisks []
Specifies when Windows should set the Usage property of physical disks missing from a storage pool to Retired.
The acceptable values for this parameter are:
-Auto This is the default setting for storage pools. When set to Auto, Windows retires missing disks, but
doesn't automatically rebuild affected virtual disks unless there are physical disks whose Usage value is set
to HotSpare, in which case Windows rebuilds the virtual disks five minutes after the failed write operation.
-Always This is the recommended setting when using free pool space to rebuild storage spaces instead of using
hot-spare disks. When set to Always, Windows retires missing physical disks and automatically rebuilds
affected virtual disks five minutes after the failed write operation.
-Never When set to Never, Windows never retires missing physical disks.
Required? false
Position? named
Default value none
Accept pipeline input? false
Accept wildcard characters? false
-ThinProvisioningAlertThresholds []
Specifies how full a storage pool must get (in percent) before an alert is generated to add physical disks to
the storage pool to support thinly provisioned virtual disks.
Required? false
Position? named
Default value none
Accept pipeline input? false
Accept wildcard characters? false
-ThrottleLimit []
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 PowerShellr 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.
Required? false
Position? named
Default value none
Accept pipeline input? false
Accept wildcard characters? false
-UniqueId
Specifies the UniqueID of the storage pool for which you want to set attributes.
Required? true
