Recently one of my customer’s HYPER-V environment recovered from power failure. Despite having secondary power to maintain the servers up and running switches redundancy power has not been overlooked . Nevertheless after the power restore some of the VM’s in the cluster has been started acting funny inside the HYPER-V manager console.
When I overlook at the cluster MMC VM’s status is in good mode without any errors. In the particular node event viewer throwing the event id 19050. Further searching on the search engine gave me this result, not much help though. Based on the scenario we knew VM is functioning properly and this has to be intermittent problem. Our final resolution has been restart the VM and let the VM move to correct host based on the priority order.
If you’re virtualization expert (on Microsoft world ) you’re well aware above feature is possible when we implement System Center Virtualization Manager (SCVMM) to manage the HYPER-V cluster. Not every customer can afford to have System Center Datacenter SKU purchase right?
Virtual machine load balancing comes in exact time to help you do that without SCVMM. In a nutshell we can monitor the CPU and memory usage on the host an based on the pre-defined rules and allow VMs to move across the HYPER-V nodes in the cluster.
Do we have option to configure this parameter? Why not we can configure the aggressiveness of the this feature by using parameter ‘AutoBalancerLevel’. To control the aggressiveness run the following in PowerShell:
(Get-Cluster).AutoBalancerLevel = <value>
VM auto balancing can be configured via GUI and PowerShell both.
In the cluster properties right-click on your cluster name and select the “Properties” option
Select the “Balancer” pane
From the PowerShell command point of view,
(Get-Cluster).AutoBalancerMode = <value>
Parameter values are,
PS: VM autobalancing is enable by default in server 2016. If you use SCVMM 2016 to manage the cluster then this feature will be disabled.
Don’t we all love some hush hush news come in advance to our attention? Well Microsoft just did it again If you’re a VMware customer then it’s time for you to pause your renewal and give attention to Microsoft direction and offering. Microsoft is ready to give away big surprise!!!
Ok let me make it short and come to the core story
If you switch from VMware to Hyper-V from during September 1, 2016, through June 30, 2017, you can get free Windows Server Datacenter licenses when buying Windows Server Datacenter + Software Assurance. That ultimately means you only pay for Software Assurance.
All the latest information about this offer and how to calculate the TCO can be found in here. If you’re wondering what kind of enhancement HYPER-V 2016 can provide then you’ll be surprised too. Detail information can be found here.
So for my VMWare customers all I can say is don’t delay this opportunity, contact your Microsoft Account Manager and start engaging on this process.
When it comes to deployment or if you need support from the beginning stage then feel free to get in touch with Infront team
Microsoft released the latest Linux Integration Services (LIS) for the guest Linux VM’s running on HYPER-V. With this latest update following improvement has been introduced.
•Expanded Releases: now applicable to Red Hat Enterprise Linux, CentOS, and Oracle Linux with Red Hat Compatible Kernel versions 5.2, 5.3, 5.4, and 7.2.
•Manual Memory Hot Add.
You can get the latest LIS from here.
Microsoft released new tool for System Administrators to monitor the Active Directory replication. This reminds me the good old command line “repadmin”. This tool will go beyond that and provide more information than what given by CSV file output. Apart from that one of the tool I really love when it comes to AD monitoring is Quest tools which acquired by Dell.
The Active Directory Replication Status Tool (ADREPLSTATUS) analyzes the replication status for domain controllers in an Active Directory domain or forest. ADREPLSTATUS displays data in a format that is similar to REPADMIN /SHOWREPL * /CSV imported into Excel but with significant enhancements.
Specific capabilities for this tool include:
Expose Active Directory replication errors occurring in a domain or forest
Prioritize errors that need to be resolved in order to avoid the creation of lingering objects in Active Directory forests
Help administrators and support professionals resolve replication errors by linking to Active Directory replication troubleshooting content on Microsoft TechNet
Allow replication data to be exported to source or destination domain administrators or support professionals for offline analysis
Considering the detail level information provided by this tool I would say this is must for System Administrators J
This is not a latest news but thought sharing with you all an myself J.
Once you download and setup the tool it will scan the environment and provide you reports on the assessment. Reports can provide in details level descriptions as well. This tool work across physical and virtual machine environment.
- This tool will provide a high level checklist and a detailed report.
- The checklist outlines areas which are ready to move and areas which may need additional configuration or design changes.
- The detailed report offers expert guidance and advice tailored to your environment.
