Chapter 2 Starting and Stopping Daemons

This chapter explains how to activate and stop different daemons provided by AdvancedCopy Manager.

For more information on how to activate and stop the daemons described in this chapter, see "Start/Stop Daemon Commands."

2.1 Daemons that Configure AdvancedCopy Manager 

Agent of AdvancedCopy Manager is configured with the following daemons:

[Table 2.1 Types of daemons that configure Agent of AdvancedCopy Manager]

In cluster operation, the following daemon composes storage server transactions:

[Table 2.2 Type of daemon composing storage server transactions]

The following daemon cannot compose a storage server transaction:

• Communication daemon (local daemon)

2.2 Starting a Daemons 

Normally, the AdvancedCopy Manager daemons are automatically activated. However, if activation fails or the daemon is stopped, activate the daemon on each server by executing the following command:

# /opt/swstorage/bin/startacm

• Before executing the startacm command, make sure that environment variable SWSTGNODE is not set.

In cluster operation, the cluster system activates the daemon automatically.

To start the daemon separately of certain AdvancedCopy Manager transactions for some reason, follow the steps described below.

You must start the daemon for each AdvancedCopy Manager transaction (including storage local transactions). Take the following steps for the respective transactions.

1. Execute the following command on the command line:

   # ps -ef | grep stgxfws

   
   

   Confirm that command execution does not display:

   /opt/FJSVswstf/bin/stgxfws logical-node-name

   If the message above is displayed, the daemon has already started.

2. For environment variable SWSTGNODE, specify the name of the logical node on which the transaction is to be performed.

3. Start the communication daemon.

   For the startup command, see "Start/Stop Daemon Commands" in this manual.

2.3 Stopping a Daemons 

Stop daemons from the Storage management server and the Storage server. Normally, they are automatically stopped when the system stops.

To stop a daemon on a server, execute the following command on the server:

# /opt/swstorage/bin/stopacm

• Before executing the stopacm command, make sure that environment variable SWSTGNODE is not set.

In cluster operation, stop the daemon from the cluster system. For the stop procedure, see the relevant cluster software manual.

To stop the daemon separately of certain AdvancedCopy Manager transactions for some reason, follow the steps described below.

You must stop the daemon in each AdvancedCopy Manager transaction (including storage local transactions). Take the following steps for the respective transactions.

1. Execute the following command on the command line:

   # ps -ef | grep stgxfws

   
   

   Confirm that command execution displays:

   /opt/FJSVswstf/bin/stgxfws logical-node-name

   If the message above is not displayed, the daemon has already stopped.

2. For 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 stop command, see "Start/Stop Daemon Commands" in this manual.
