I know many of the build administrators are deploying the Task
Sequence on unknown device collection. I purpose and the idea behind it is to
do not deploy the task sequence on a production device and prevent accidental
data loss.
If the machine is in SCCM collection and we want to run the task
sequence on it, we must SCCM Console and do a manual deletion job and wait for
a couple of minutes to restart the imaging on the target machine
This is a time-consuming and repetitive task for us. Can we create
a way to do this in an automotive way? Like, create the PowerShell Script,
which will automatically read the machine's MAC Address and connect to the SCCM
database from the WinPE environment for getting all the hostnames to hold by
that mac address and delete each.
Also, can we do a diskpart at the same time to avoid further
imaging failure? Yes we can create the PowerShell Script and integrate it
with Boot Image, which will automatically check whether the machine having an
internal storage device attached or not, and based on the results script will
perform Diskpart operation, if the internal storage device is faulty or not
connected in BIOS, the script will prompt the error.
We can achieve the below business benefits: -
·
Rectify internal Hard Disk Errors and Save imaging time instantly
·
Save the Boot Stick recreation time
·
Avoid multiple restarts unnecessarily
·
Find exact RCA for internal HDD failure and avoid unnecessary
troubleshooting
·
Reduce imaging build time as1hrs/imaging
·
Increase tech support productivity
·
Avoid daily repeated and headache tasks
· Make a user-friendly imaging process
let's do it.......
We must create one txt file which will help us to do the diskpart
while executing PowerShell.
this text file includes
select disk 0
clean
exit
or you can use sel disk 0 "0" is
representing the number of attached HDD/SSD hard drive. you can change it
according to your requirement.
save this text file as dc_diskpart.txt
Second, we have to create one PowerShell script. which include
your SCCM Primary site server FQDN and Site code along with the SCCM
administrator's username and password.
Create PS1 file and insert the below code into it and save it as
Diskpart.PS1
create one folder and keep both the txt and ps1 file in one folder
called "SmartDiskPart"
Create SCCM package and distribute on require DPs.
Now, select Boot Image properties and navigate to the
Customization tab and add the DiskPart package, and add command line as PowerShell.exe -executionpolicy bypass -file Diskpart.ps1
· PROCEDURE: -
- Boot the machine from PXE or Boot Media and provide the credentials for further processing.
- Once you enter the Boot media password, the PowerShell script will execute the diskpart program, and ask you for your input as shown below screenshot.
- If an internal disk drive
is not present the script will throw the error as shown in the below screenshot
- Based on your input, the script will run the next part of the program and goes to the next step (Stale Record management-SCCM).
This step also asks you for your input as shown in the below screenshot.
- Getting your machine mac addresses
- Based on your machine mac
address we are checking the machine in the SCCM database.
- Be there Now we have found your machine in the SCCM database. Don't worry we will clean it..... Once the hostname is deleted from the SCCM database we have created 120 seconds wait time to pause the script and till the SCCM database updates to Task Sequence make available for the machine.
- Woo!!! Hostname entry
deleted from SCCM database.
- Task Sequence will
continue after finishing the PowerShell program execution.
- Once you click on Next, Task Sequence will start execution.
Below is the PowerShell script you have to use for this
automation. Enjoy and do let me your feedback.

.SYNOPSIS
This script will handle Stale Hostname entry(s) management and Diskpart during the Imaging process.
.DESCRIPTION
While tech guys are going to image the machines with Boot Media, they should diskpart the machine and wipe all partitions from the internal Hard Disk Drive. Sometimes internal disk having some issues and it’s not getting connected to the laptop and then when tech guys are performing diskpart with select disk 0. The external storage device is getting selected on select disk 0 and the same got formatted mistakenly. If deployed all the production task sequences on Unknown Computers collection. While tech guys are going to image the machines with PXE/Boot Media and if a machine is the part of existing collection and is present in the SCCM database, Task Sequence will fail. Then tech guys need to collect the MAC Address and Serial Number of that machine and provide the same over mail with us to clear the entry from the SCCM database. Based on details shared by Tech Guys, then we need to check the machine on the SCCM database and delete the entry(s) and revert on mail for further processing.
