You can manually rebalance through the cluster health check, or by using RVC commands.
If the Virtual SAN disk balance health check fails, you can initiate a manual rebalance in the vSphere Web Client. Under Cluster health, access the Virtual SAN Disk Balance health check, and click the Rebalance Disks button.
Use the following RVC commands to manually rebalance the cluster:
vsan.check_limits. Verifies whether any capacity device in the Virtual SAN cluster is approaching the 80 percent threshold limit.
vsan.proactive_rebalance [opts]<Path to ClusterComputeResource> –start. Manually starts the rebalance operation. When you run the command, Virtual SAN scans

Virtual SAN automatically rebalances the Virtual SAN cluster when a capacity device reaches 80 percent utilization. Rebalancing also occurs when you place a Virtual SAN host in maintenance mode.Its By Default.
Run the following RVC commands to monitor the rebalance operation in the cluster:
vsan.check_limits. Verifies whether the disk space utilization is balanced in the cluster.
vsan.whatif_host_failures. Analyzes the current capacity utilization per host, interprets whether a single host failure can force the cluster to run out of space for reprotection, and analyzes how a host failure might impact cluster capacity, cache reservation, and cluster components.

Most of the times we need the logon duration for the different things and we start searching for the script everywhere on the web. Now here is an script which comes up with this solution.
Hope you all like it.
This script covers the entire logon process, from the moment the user clicks on the published resource until the Desktop is available.
The new module works by querying the XenDesktop Monitor service via 0Data API. The Windows session ID is translated to a XenDesktop SesionKey which is used in the 0Data API query.

vCloud Air Dedicated Cloud is a single-tenant, physically isolated IaaS platform that is operated by VMware and compatible with your on premises vSphere environments for true Hybrid functionality. Dedicated Cloud is your own private cloud instance in the public cloud as it provides customers with their own compute nodes for utmost security. This solution offers users the additional flexibility to assign resources to separate virtual data centers, each with individual user access controls. Dedicated Cloud includes compute resource reservation control—the entire compute and memory allocation is reserved and can be allocated or over-committed as you desire.

Today I seen a strange issue in my production environment .
Issue : The Vm (OS : Linux –Centos X) is showing an error and shutdown itself after flashing the message.
Cause : This is the issue both in vmware/Linux itself. Reason VMware doesn’t actually provide that level interface for CPU access, but Ubuntu try to load the kernel module anyway.
Resolution. For fixing this you need to go in to the Single user mode of the Impacted VM and blacklist the component which is causing error to boot up the OS.
Hope all knows how to goes … Read The Rest ......
Today I was thinking why 2 data store is used by the Hearbeating for the HA wherever FDM roles follow. Then I tried to find out the difference between both of them. I did some observation and find some interesting thing which I should say you must know about it. So lets start..
First of all how you will find out the datastore participating in heartbeating for HA. Quite easy but would like to share it again. you can just go to HA enabled cluster>Cluster status.
Now find the datastore which are selected in the list and browse … Read The Rest ......
