Description

The Remove-HpcDriver cmdlet removes one or more specified device drivers. You specify the device drivers by using either HpcDriver objects or the names of the setup information (.inf) files for the device drivers. Do not include the paths for the .inf files.

Examples

Example 1: Remove a device driver

PS C:\>Remove-HpcDriver -Name "MyDriver.inf"

This command removes the device driver that has a setup information (.inf) file named MyDriver.inf.

Example 2: Remove drivers in a head node

PS C:\>Remove-HpcDriver -Name "Driver01.inf,Driver02.inf" -Scheduler "Headnode"

This command removes the device drivers that have setup information (.inf) files named Driver01.inf and Driver02.inf on the HPC cluster with a head node named Headnode.

Example 3: Get a driver and remove it

PS C:\>Get-HpcDriver -Name "MyDriver.inf" | Remove-HpcDriver

This command gets the HpcDriver object for the device driver that has a setup information file named MyDriver.inf, and then removes that device driver by redirecting that HpcDriver object to the Remove-HpcDriver cmdlet.

Parameters

-ClusterConnectionString

Specifies an array of cluster connection strings for the cluster to which you want to add the device drivers. The value format is host1,host2,host3. If you do not specify the ClusterConnectionString parameter, this cmdlet uses the connection string on the head node that the CCP_CONNECTIONSTRING environment variable specifies. To set this environment variable, run the following cmdlet: Set-Content Env: CCP_CONNECTIONSTRING \<head_node_name\>.

This parameter was introduced in HPC Pack 2016.

Type:String[]
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-Confirm

Prompts you for confirmation before running the cmdlet.

Type:SwitchParameter
Aliases:cf
Position:Named
Default value:False
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-Driver

Specifies an array of HpcDriver objects for the device drivers that you want to remove. Use the Get-HpcDriver cmdlet to get the HpcDriver objects for the device drivers.

Type:HpcDriver[]
Position:Named
Default value:None
Required:True
Accept pipeline input:True
Accept wildcard characters:False

-Name

Specifies an array of file names for the setup information (.inf) files for the device drivers that you want to remove. You do not need to include paths for the .inf files. Use the Get-HpcDriver cmdlet to view the file names of the .inf files for the device drivers in the HPC cluster.

Type:String[]
Position:1
Default value:None
Required:True
Accept pipeline input:False
Accept wildcard characters:False

-Scheduler

Specifies the host name or IP address of the head node for the cluster that includes the device drivers. The value must be a valid computer name or IP address. If you do not specify the Scheduler parameter, this cmdlet uses the scheduler on the head node that the CCP_SCHEDULER environment variable specifies. To set this environment variable, run the following cmdlet:

Set-Content Env:CCP_SCHEDULER \<head_node_name\>

Type:String[]
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-WhatIf

Shows what would happen if the cmdlet runs. The cmdlet is not run.

Type:SwitchParameter
Aliases:wi
Position:Named
Default value:False
Required:False
Accept pipeline input:False
Accept wildcard characters:False

Inputs

HpcDriver[]

Outputs

None

Notes

  • The built-in ConfirmImpact setting for this cmdlet is Medium. If this ConfirmImpact setting is equal to or higher than the value of the $ConfirmPreference variable for your environment, the cmdlet prompts for confirmation unless you specify -Confirm:$False. If this ConfirmImpact setting is lower than the value of the $ConfirmPreference variable for your environment, the cmdlet does not prompt for confirmation unless you specify -Confirm or -Confirm:$True.

  • You must be a cluster administrator to run this cmdlet successfully.
