2.3.2 Stopping daemons without stopping the operating system

If you want to stop a daemon without stopping the operating system, you can perform the action described below on the appropriate server.

Storage Management Server and Storage Server

For details, refer to "Starting and Stopping Daemons" in the "ETERNUS SF AdvancedCopy Manager Operator's Guide" for the operating system of the target Storage Management Server and Storage Server.

Tape Server

To stop daemons, execute the following commands as the root user.

# /etc/init.d/initTSM stop
# /etc/init.d/FJSVswstm stop
# /opt/swstorage/bin/stopacm

Note

Before executing the stopadacm command, confirm that the SWSTGNODE environment variable is not defined.

Note

If daemons are stopped while backup or restoration is in progress, the backup or restoration terminates with an error. If necessary, restart daemons and execute the backup or restoration again.

Note

If you need to stop the daemon on the Tape Server individually, you can stop the daemon as follows.

In the case of the Communication Daemon
1. The following commands are executed at a command line.
  # ps -ef | grep stgxfws
  Confirm that the following is displayed:
  /opt/FJSVswstf/bin/stgxfws Logical-Node-Name
  If the message above is not displayed, the daemon has already stopped.
2. For the environment variable SWSTGNODE, specify the name of the logical node on which the transaction is to be performed.
3. Stop the Communication Daemon.
  For the daemon stop command, see "11.6 Starting and Stopping Daemons" of the chapter "Chapter 11 Commands".
Note
If you execute the command to stop the communication daemon while it is running, the command may take up to 10 seconds to complete.
In the case of daemons other than the Communication Daemon
Refer to "11.6 Starting and Stopping Daemons" in the chapter "Chapter 11 Commands". A logical node name is set as an environment variable SWSTGNODE, and a daemon stop command is executed.
