For troubleshooting purposes, you can download an ESXi component of the I/O filter, packaged as a VIB file, and install it on the ESXi host. Use the esxcli command to install the VIB file.
When you specify a target server by using --server=server_name, the 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, or run esxcli --help at the vCLI command prompt.
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.
