With the cell subcommand of the VMware Cloud Director cell management tool, you can suspend the task scheduler so that new tasks cannot be started, view the status of active tasks, control cell maintenance mode, or shut down the cell gracefully.

Note: Starting with VMware Cloud Director 10.5.1, you can manage a cell by using the Service Provider Admin Portal. See View and Manage Your VMware Cloud Director Cell Infrastructure.
To manage a cell, use a command line with the following form:
cell-management-tool cell -u sysadmin-username -p sysadmin-password option
where sysadmin-username and sysadmin-password are the user name and password of the system administrator.
Note:

For security reasons, you can omit the password. In this case, the command prompts you to enter the password without displaying it on the screen.

As an alternative to providing the system administrator credentials, you can use the --pid option and provide the process ID of the cell process. To find the process ID of the cell, use a command like the following.
service vmware-vcd pid cell
