[<CommonParameters>]Description
The Set-MPIOSetting cmdlet changes Microsoft Multipath I/O (MPIO) settings. The settings are as follows:
- PathVerificationState
- PathVerificationPeriod

Examples
Example 1: Change the disk time-out
PS C:\> Set-MPIOSetting -NewDiskTimeout 30This 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.

| Type: | Int32 |
| Position: | 5 |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
