Use the esxcli command to obtain information about the locking mechanism that a VMFS datastore uses.

In the procedure, --server=server_name specifies the target server. The specified target server prompts you for a user name and password. Other connection options, such as a configuration file or session file, are supported. For a list of connection options, see Getting Started with vSphere Command-Line Interfaces.

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 --server=server_name storage vmfs lockmode list

Results

The table lists items that the output of the command might include.
Table 1. VMFS Locking Information

ATS upgrade pending The datastore is in the process of an online upgrade to the ATS-only mode.
ATS downgrade pending The datastore is in the process of an online downgrade to the ATS+SCSI mode.
ATS Compatible Indicates whether the datastore can be or cannot be configured for the ATS-only mode.
ATS Upgrade Modes Indicates the type of upgrade that the datastore supports.
None The datastore is not ATS-only compatible.
Online The datastore can be used during its upgrade to the ATS-only mode.
