Administration and Diagnostics Utilities - Oracle Exadata Recipes: A Problem-Solution Approach - page 162

The commands inside /etc./init.d/celld actually perform cellcli -e alter cell commands to stop and start
the RS, MS, and cellsrv processes; both approaches will yield the same result.
You can also manage individual processes (RS, MS, or cellsrv ) manually using CellCLI alter cell commands.
For example, to restart the cellsrv software, you could run the following command:
[root@cm01cel01 ~]# cellcli -e alter cell restart services cellsrv
Restarting CELLSRV services...
The RESTART of CELLSRV services was successful.
[root@cm01cel01 ~]#
Rebooting a healthy storage server will nearly always leave you in a good state in terms of overall cell health and
functionality since the overall storage server processes are automatically started from system initialization scripts.
During patching and upgrades, which are presented in Recipe 11-1, Oracle's patching software will commonly stop,
start, or restart Cell Services software components.
7-6. Administering Storage Cells Using CellCLI
Problem
You wish to list, modify, create, drop, or manage objects and attributes for your Exadata storage cells.
Solution
Oracle's storage cell command line interface is called CellCLI. CellCLI is invoked by running the cellcli command
when logged in to a storage server.
Log in to your desired storage cell as root , celladmin , or cellmonitor and issue the cellcli command:
[celladmin@cm01cel01 ~]$ cellcli
