The cell management tool is a command-line utility that you can use to manage a vCloud Director cell or database. Superuser or system administrator credentials are required for most operations.

The cell management tool is installed in /opt/vmware/vcloud-director/bin/cell-management-tool.

To list the available cell management tool commands, use the following command line.

cell-management-tool -h

[root@cell1 /opt/vmware/vcloud-director/bin]# ./cell-management-tool -h

usage: cell-management-tool
-h,--help   print this message

Available commands:
cell - Manipulates the Cell and core components
certificates - Reconfigures the SSL certificates for the cell
ciphers - Reconfigure the list of disallowed SSL ciphers for the cell
configure-metrics - Collects and stores properties necessary for collecting and querying metrics data
dbextract - Exports the data from the given set of tables
fix-scheduler-data - Scan database for corrupt scheduler data.  Fix scheduler job data if corrupt.
generate-certs - Generates self-signed SSL certificates for use with vCD cell.
recover-password - Change a forgotten System Administrator password. Database credentials are required.
fail-tasks - Fail all tasks running on this cell and set a custom failure message.

For command specific help:
 cell-management-tool <commandName> -h

Use the cell command of the cell management tool to suspend the task scheduler so that new tasks cannot be started, to check the status of active tasks, to control cell maintenance mode, and to shut down the cell gracefully.

Use the dbextract command of the cell management tool to export data from the vCloud Director database.

If you know the vCloud Director database username and password, you can use the fix-scheduler-data command of the cell management tool to scan the database for corrupt scheduler data and repair that data as needed.

Use the certificates command of the cell management tool to replace the cell's SSL certificates.

Use the generate-certs command of the cell management tool to generate new self-signed SSL certificates for the cell.

Use the ciphers command of the cell management tool to configure the set of cipher suites that the cell offers to use during the SSL handshake process.

Use the ssl-protocols command of the cell management tool to configure the set of SSL protocols that the cell offers to use during the SSL handshake process.

Use the configure-metrics command of the cell management tool to connect the cell to the optional metrics database.

If you know the vCloud Director database username and password, you can use the recover-password command of the cell management tool to recover the vCloud Director system administrator password.

Use the fail-tasks command of the cell management tool to update the completion status associated with tasks that were running when the cell was deliberately shut down. You cannot use the fail-tasks command unless all cells have been shut down.

Use the configure-audit-syslog command of the cell management tool to configure the way the system logs audit messages.

Use the reconfigure-database command of the cell management tool to update connection properties for the vCloud Director database. This command cannot be used to change the database type or migrate data to another database instance.

Use the system-setup command of the cell management tool to initialize the server group's database with a system administrator account and related information.

Use the manage-email command of the cell management tool to manage the templates that the system uses when creating email alerts.

Use the find-orphan-vms command of the cell management tool to find references to virtual machines that are present in the vCenter database but not in the vCloud Director database.

Use the configure-ceip command of the cell management tool to join or leave the VMware Customer Experience Improvement Program (CEIP).
