Administrator Guide

1 From the Console VM, open Event Viewer, connect to the cluster node that needs attention remotely, and Save All Events As.
2 Open the VMM console, open the Jobs workspace, and check for failed Refresh host cluster jobs.
3 In the error details for each of the failed jobs, check for the following error:
Error (2912)
An internal error has occurred trying to contact the <Server_FQDN> server:
: .
WinRM: URL: [http://<Server_FQDN>:5985], Verb: [ENUMERATE],
Resource: [http://schemas.microsoft.com/wbem/wsman/1/wmi/root/cimv2/
Win32_AssociatedProcessorMemory],
Filter: []
Unknown error (0x80041013)
4 On the Console VM, open a command prompt, and run the following command to nd out whether any of the WinRM errors still
persist:
Gwmi -class "Win32_AssociatedProcessorMemory" -ComputerName "ServerName"
5 If the issue persists, collect Application and System event logs, and then restart the compute cluster host.
The restart initiates autorefresh jobs in VMM, which refresh the status of the host and VMs running on the host.
NOTE: VMM automatically refreshes the status of clustered hosts and VMs at these intervals:
• A Refresh host cluster job runs every 30 minutes.
• A Refresh virtual machine light refresh job runs once every hour.
Recovering after a power outage
There are occasions where a power outage may cause the Dell Hybrid Cloud System for Microsoft stamp to shut down unexpectedly.
When power becomes available again, the stamp will power on automatically without any manual intervention.
The following hardware devices will power on immediately:
• JBODs.
The following hardware components will power on with a delay of 1-10 minutes:
1 File server cluster hosts
2 Compute cluster hosts
Approximately 2 hours after power up, the stamp is expected to be in a functional state. You must perform the following steps 2 hours after
power up.
Prerequisites
Prepare a laptop if iDRACs are connected.
If the iDRACs are connected in the environment, Dell recommends that you use a laptop to perform these tasks:
1 Connect the laptop to port 39 or 40 of the switch of the Dell Hybrid Cloud System for Microsoft stamp. This switch is the network
switch that you use for management of Dell Hybrid Cloud System for Microsoft infrastructure components through iDRAC
connections.
2 Congure the laptop with a static IP address from the iDRAC subnet range. This step enables network communication to the iDRACs
in the Dell Hybrid Cloud System for Microsoft stamp.
3 Install Java version 7—or a later version—on this laptop so that you can start the virtual console through the iDRAC interface.
Ensure AD DS services are available.
