Sometimes we may need to take snapshot of the vm but we don’t have enough space in our datastore.In that case we can change the snapshot directory by editing vmx file.

Shell.log is the one of the log file which helps us to resolve problems and in some scenarios it will help us to do the audit process.

Example 1

1. With the below example we can see that per-worker-01a vm is runnin on esx-01a.

In few hours later we can notified that vm has powered off. We could nt find any logs in vCenter or in the os level.

What we can do is we can check the shell.log file. If someone has powered off the vm using command line on the ESXi , we can find the details.

In the above shell.log file we can see that someone has tried to power off this vm.

some times we are facing that vmdk locked scenario which we need to identify the locked file using vmkfstools.  But when we having multiple vmdk files, we need to run this command several times. To overcome this issue I have tried to use for loop in esxi shell. This may be help others when they having same problem.

for files in *.vmdk

>do

>vmkfstools -D ${files}

>done

We can use VMware operations manager to find powered off vms, idle vms & oversized vms easily.

1. Login to the vRops

2. Click on reclaim

3. From the powered off category we can select and delete the vms

4. same way we can find idle vms

5. we can select & delete snapshots
