Use the esxcli command to obtain information about the locking mechanism that a VMFS datastore uses.
Prerequisites
Install vCLI or deploy the vSphere Management Assistant (vMA) virtual machine. See Getting Started with vSphere Command-Line Interfaces. For troubleshooting, run esxcli commands in the ESXi Shell.
Procedure
- ♦ To display information related to VMFS locking mechanisms, run the following command:
esxcli storage vmfs lockmode list
