Updated: June 4, 2014

Applies To: Windows 8.1, Windows PowerShell 4.0, Windows Server 2012 R2

Reset-StorageReliabilityCounter

Resets storage reliability counters for a disk.

Syntax

Parameter Set: ByPhysicalDisk
Reset-StorageReliabilityCounter -PhysicalDisk <CimInstance> [-AsJob] [-CimSession <CimSession[]> ] [-PassThru] [-ThrottleLimit <Int32> ] [ <CommonParameters>]

Parameter Set: ByVirtualDisk
Reset-StorageReliabilityCounter -Disk <CimInstance> [-AsJob] [-CimSession <CimSession[]> ] [-PassThru] [-ThrottleLimit <Int32> ] [ <CommonParameters>]

Parameter Set: InputObject (cdxml)
Reset-StorageReliabilityCounter -InputObject <CimInstance[]> [-AsJob] [-CimSession <CimSession[]> ] [-PassThru] [-ThrottleLimit <Int32> ] [ <CommonParameters>]




Detailed Description

The Reset-StorageReliabilityCounter cmdlet resets the storage reliability counters to zero for a virtual disk or physical disk. The cmdlet resets the following storage reliability counters for I/O operations: read latency, write latency, and flush latency. If an unexpected issue with a disk or driver causes high latency, use this cmdlet to discount the sharp rise in latencies when you monitor I/O performance.

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.

-CimSession<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.

-Disk<CimInstance>

-PhysicalDisk<CimInstance>

Specifies a physical disk as a CIMInstance object. The cmdlet resets the storage reliability counter for the physical disk that you specify. To obtain a physical disk object, use the Get-PhysicalDisk cmdlet.

-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.

Examples

Example 1: Reset the reliability counters for two physical disks

The first command gets the storage reliability counters for the physical disk named PhysicalDisk01, and stores the counters in the $Counter1 variable.

The second command gets the storage reliability counters for the physical disk named PhysicalDisk02, and stores the counters in the $Counter2 variable.

The last command resets the storage reliability counters for the physical disks stored in $Counter1 and $Counter2.


PS C:\> $Counter1 = Get-StorageReliabilityCounter -PhysicalDisk (Get-PhysicalDisk "PhysicalDisk01")
PS C:\> $Counter2 = Get-StorageReliabilityCounter -PhysicalDisk (Get-PhysicalDisk "PhysicalDisk02")
PS C:\> Reset-StorageReliabilityCounter -InputObject $Counter1, $Counter2
