is the datastore still available and not missing ?

Your other VMs report host unknown as well.

I do not have backup so that I could restore.  I will have to take this as a lesson hence please suggest me backup software, also is there any possibility at this stage.

Question:  Is your host connected to the SAN via iSCSI?  Check your iSCSI settings and make sure that all targets are connected back after the reboot.  If they aren't, this could be a reason why you don't see your VM because its on a specific target.

Veeam Backup and Replication.

As for recovery software we've had success wit the following commercial products, free to download and try, but you'll need to pay for recovery.

Thank you very much, if we go for Veeam Backup and Replication does it require storage as at present we do not have storage all VM's are running on server local disks. I am looking for complete VM based backup.
David Johnson, CD, MVPRetiredCommented:
Yes it requires some sort of storage.  It can run in a VM.

You mean that the VM's don't have ESXI storage but use pass through disks?
Andrew Hancock (VMware vExpert / EE Fellow)VMware and Virtualization ConsultantCommented:
You need to ensure your backups are off your HOST, otherwise your backups are a single point of failure, if the host fails.
so you've checked the VM store is available and a directory's there for the VM's files but the files are missing?
Not good.
Do you know any of their filename? you could search the storage to see if they have moved.
is this related to your other question on creating a new server for file shares/backup DC? could you have selected the wrong server when performing a task or deleting a disk?

Thanks all, VM name and the directory name in the data browsers was different I understand this due to manual rename, the virtual machine disk file listed in the data browser was virtual machine flat file hence had to recreate the virtual machine disk descriptor file. followed the steps this worked.https://kb.vmware.com/s/article/1002511. thanks for all every information from all of you was very useful. thanks once again.

You should really have backups!

Yes, backup practice should never be optional, I have taken it seriously. Thank you.
