Appendix A. Administration and Configuration Reference
This section provides information about administering, monitoring, tuning, and
connecting the storage agent.
Starting and Stopping the Storage Agent
The storage agent can be configured to start automatically upon system reboot. It
can also be started and stopped manually. The following is a description of these
tasks.
Automating the Storage Agent Startup
The storage agent is configured to start automatically at the time of installation. An
entry is made to the inittab to enable automatic start up. The storage agent
automatically restarts and runs in the background when the operating system is
rebooted.
During the installation process, the etc/inittab is updated with the following
command to enable automatic startup:
mkitab autostgagnt:2:once:"/usr/tivoli/tsm/StorageAgent/bin/rc.tsmstgagnt
>/dev/console 2>&1 #Start the Tivoli Storage Manager storage agent"
If you decide that you do not want the storage agent to start automatically, you
can issue the following command to remove the statement from the /etc/inittab.
rmitab "autostgagnt"
Manually Starting and Stopping the Storage Agent
Start the storage agent by accessing the storage agent directory and issue the
following command:
dsmsta
Stop the storage agent by typing the following command at the command line
prompt:
halt
Note that you can also use an administrative client to issue commands supported
by the storage agent.
In most cases it is not necessary to halt and restart a LAN-free storage agent to
pick up changes from the data manager server. However, restarting the storage
agent may be necessary if an attempt was made to change storage pool, library,
device class, or drive information while LAN-free data movement was in process.
The effects on LAN-free storage pools resulting from such an attempted change are
not critical enough to create serious problems. The storage agent keeps a list of
storage pools, libraries, and device classes in memory to determine potential
LAN-free destinations. Target volume selection occurs on the data manager server.
Certain storage pool attributes can result in failed requests rather than the desired
LAN failover by the storage agent. If the storage agent accurately identifies a
LAN-free destination, the LAN-free operation will most likely be successful.
