Syntax

Parameter Set: __AllParameterSets
Set-MPIOSetting [[-NewPathVerificationPeriod] <Int32> ] [[-NewPathVerificationState] <String> ] [[-NewPDORemovePeriod] <Int32> ] [[-NewRetryCount] <Int32> ] [[-NewRetryInterval] <Int32> ] [[-NewDiskTimeout] <Int32> ] [[-CustomPathRecovery] <String> ] [[-NewPathRecoveryInterval] <Int32> ] [ <CommonParameters>]

Detailed Description

The Set-MPIOSetting cmdlet changes Microsoft Multipath I/O (MPIO) settings. The settings are as follows:

-- PathVerificationState
-- PathVerificationPeriod
-- PDORemovePeriod
-- RetryCount
-- RetryInterval
-- UseCustomPathRecoveryTime
-- CustomPathRecoveryTime
-- DiskTimeoutValue

You may be prompted to restart the computer for your changes to take effect.

Parameters

-CustomPathRecovery<String>

Specifies whether MPIO performs custom path recovery. The acceptable values for this parameter are: Enabled and Disabled. The default value is Disabled.

-NewDiskTimeout<Int32>

Specifies the disk timeout value, in seconds. This value is the length of time the server waits before it marks the I/O request as timed out. The default value for DiskTimeoutValue is 120. We recommend a maximum value of 30.

-NewPathRecoveryInterval<Int32>

Specifies a custom path recovery time, in seconds. This is the length of time before the server attempts path recovery. The default value is 40. This parameter is not relevant unless the CustomPathRecovery parameter has the value Enabled.

-NewPathVerificationPeriod<Int32>

Specifies a path verification period, in seconds. This is the length of time for the server to verify every path. This parameter is not relevant unless the path verification state has a value of Enabled. The default value is 30.

You can set the path verification state by using the NewPathVerificationState parameter.

-NewPathVerificationState<String>

Specifies whether to enable path verification. The acceptable values for this parameter are: Enabled and Disabled. The default value is Disabled.

-NewPDORemovePeriod<Int32>

Specifies a physical device object (PDO) removal period, in seconds. This period is the length of time the server waits after all paths to a PDO have failed before it removes the PDO. The default value is 20.

-NewRetryCount<Int32>

Specifies the number of times to retry an I/O request. The default value is three times.

-NewRetryInterval<Int32>

Specifies a retry interval, in seconds. This is the length of time after which the server retries a failed I/O request. The default value is one second.
