Explanation:
ESX ESX Configuration Guide ESX 4.0 vCenter Server 4.0
When your host accesses a virtual machine disk file on an NFS-based datastore, a
.lck-XXX lock file is generated in the same directory where the disk file resides to
prevent other hosts from accessing this virtual disk file. Do not remove the .lck-XXX
lock file, because without it, the running virtual machine cannot access its virtual disk
file.
