We can use df -h command to get the file system usage.
When can we use it-Most of the time I had to use it to check the file system usage on vCenter appliance.
We can use find command to find files in the ESXi or vCenter file system
In my below example I have used it to find all the vmx files
Ex
find / -name *.vmx
We can use cat command to open a file and read the data
In my below example I have opened one of the main log file(vmkernel.log) using cat viewer
We can use grep command to search something inside the file
In my below example I used grep commands to find logged errors in the vmkernel.log
We can use ps command to fine running vm’s process

Also I have selected default vSAN policy

Operating system clustering is one of the major and popular high availability mechanism in system infrastructure products. Advantage of the os clustering is it can identify the application level failure.
As a systems administrators most of the time we may need to work with MS windows failover clusters. Most of the file servers and SQL clusters are depend on this failover cluster technology. Most of the situation one of the main requirement is this failover cluster is shared lus/disk. Earlier most of the time we sued to have minimum two physical servers for this cluster operation which is directly connect to SAN device(Shared storage). But to get the benefits of virtualization platform and reduce the cost , now we have to use same cluster features on top of the virtualization platform.
1. In my below example Im using two test virtual machines.
2. Now we need to add new scsi controller per this vm
