Expansion of existing stamp fails with “Decryption failed” error message
Expansion of an existing Dell Hybrid Cloud System for Microsoft stamp fails in the following scenario:
• The Dell Hybrid Cloud System for Microsoft stamp is at Microsoft Update version 1603 or a later version.
• The nodes that you want to add are running an earlier version of the Windows Management Framework (WMF) than what is included
in Update 1603.
When these two conditions apply, the expansion deployment fails with the message “Decryption failed. LCM failed to start desired state
conguration manually” in the verbose logs for the nodes that you want to add.
To avoid this issue, do the following before you run expansion:
1 Install WMF 5.0 RTM on the new nodes.
TIP
: You can download WMF 5.0 RTM from https://www.microsoft.com/en-us/download/details.aspx?id=50395. You
need the Win8.1AndW2K12R2-KB3134758-x64.msu package.
2 Restart the new nodes.
Paging le not large enough for automatic memory dumps
NOTE
: This section does not apply if the Microsoft update version of the Dell Hybrid Cloud System for Microsoft stamp at initial
deployment is version 1603 or a later version. To check the update version, see How to check which update package is installed.
The paging le on the physical hosts may not be large enough to support the creation of an automatic memory dump if a server crashes.
This le may be required for troubleshooting. Dell recommends that you set the paging le size to 16,384 MB (16 GB).
1 On the Console VM, open an elevated Windows PowerShell session, that is, run as Administrator.
2 Run the following command, where <hostname1>,<hostname2>,… are the names of all physical hosts in the stamp (including any
backup hosts):
WARNING
: The code set o by “Begin – Long Line” and “End – Long Line” is one continuous line of code
that has been wrapped to t in this document. It should be a single line in the script that you save and run.
# Begin - Long Line
Invoke-Command <hostname1>,<hostname2>,... {Set-ItemProperty -Path 'HKLM:\SYSTEM
\CurrentControlSet\Control\Session Manager\Memory Management' -Name PagingFiles -Value "?:
\pagefile.sys 16384 16384"}
# End - Long Line
TIP
: To nd the host names, you can use the VMM console. Or, to nd the host names in a cluster, you can run the
following Windows PowerShell command, where < ClusterName > is the name of the cluster, such as < Prex >CCL and
< Prex >SCL:
Get-ClusterNode -Cluster < ClusterName > | Format-Table –Property Name
