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.

Examples

Example 1: Change the disk time-out 

PS C:\> Set-MPIOSetting -NewDiskTimeout 30

This command sets the disk time-out value to 30 seconds. The system prompts you to restart after you change settings.

You can use the Get-MPIOSetting cmdlet to verify the change.

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

Type: Int32
Position: 7
Default value: None
Accept pipeline input: False
Accept wildcard characters: False
-NewPathVerificationPeriod

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.
