6 The package is a self-extracting executable (.exe) le named DHCS-Update-YYMM.exe, where YYMM designates the year and the

month of the updates contained in the package. Double-click the le to run the executable and extract the package contents to the

shared folder. Do the following:

a The Dell Hybrid Cloud System for Microsoft Setup Wizard opens. Click Conrm to step through the wizard.

b Click Install to extract the update package.

c Click Finish when the wizard completes.

Step 3: Ensure that Group Policy does not block the mounting of USB

virtual disks

If there are rmware and driver updates in the P&U package, make sure there are no Group Policy settings in place that block the mounting

of a USB virtual disk on any of the physical nodes. These settings can block the installation of some drivers.

1 As a domain administrator, log on a to computer that has the Group Policy Management Console (GPMC) installed.

2 Check the specied Group Policy settings at the following paths:

• \Computer Conguration\Policies\Administrative Templates\System\Removable Storage Access

Setting: All Removable Storage classes: Deny all access

• \Computer Conguration\Policies\Administrative Templates\System\Device Installation\Device Installation Restrictions

Setting: Prevent installation of removable devices

If either of these policy settings are enabled for the nodes, disable the policy setting and wait for three hours before you install rmware

and driver updates through the P&U framework.

Update the computers

Now that the patching environment is set up, you can start the patching process by running a Windows PowerShell script. This script does

the following:

1 Runs a health check to perform a basic validation of the rack you are updating.

2 Orchestrates and installs the updates in the correct order.

3 Runs a post-validation test and generates compliance reports.

To perform the patching process, do the following:

Step 1: Run a health check and x any discovered issues

As a best practice, Dell recommends that you rst run a noninvasive, read-only health check. This step ensures fundamental stamp health

before you run the actual update.

1 On the Console VM, make sure that you are logged on as the account that is a member of <

Prex

>-Setup-Admins.

2 Open an elevated Windows PowerShell session, that is, run the PowerShell session as an administrator.

IMPORTANT

: If you do not run the session as an administrator, P&U fails.

3 Run the following command, where CPSPU Folder Name is the folder name that you used for the specic update package.

\\<Prefix>CON01\PUShare\<CPSPU Folder Name>\Framework\PatchingUpgrade\Invoke-PURun.ps1–

HealthCheckOnly -PUCredential (Get-Credential)
