The console monitors storage devices on a network by
communicating with a Sun StorEdge Configuration Service Agent on the servers. When Sun StorEdge Configuration Service is started, the console software begins by establishing contact with the Sun StorEdge Configuration Service Agent on each managed server if Auto Discovery was specified when the server was configured. If Auto Discovery was not specified, you have to double-click each server and type a password to start the discovery process for that server.
Establishing a TCP/IP connection between the console and the Sun StorEdge Configuration Service Agent on each server and receiving back inventory information can take several minutes, depending on the complexity of your network. When this is occurring, the server icon in the main window displays a satellite dish icon on its right side. Once the inventory is refreshed, the satellite dish symbol is replaced by an active
server symbol. The agent on each server does a periodic scan of its inventory to
check for changes. If there is a change, the agent sends an event to the
console. Depending on the event, the console might request the inventory from that
server's last scan to use for updating the representation of the server as
displayed on the main window. During this process, the satellite dish icon is attached to the server icon, and you are not able to perform any configuration and array activity commands on that server until the refresh process is completed and the console main window is updated.
When Sun StorEdge Configuration Service is running and the server agent and console
are connected, the agent pings or transmits a periodic signal
to the console to verify the server's status. If the console does not
receive a certain number of consecutive responses (handshakes) from
the agent, the console marks the server as offline and disconnects from
the server. The server's icon is made inactive and adjacently marked
with a question mark symbol. If a nonactive server was originally made active through the Auto Discovery function, the console periodically tries to reestablish server communications. Occasionally, you might want to have an inventory performed on a server
between the periodic status. To do this, double-click the server's icon
to display the Server View window, and then click Rescan
in that window. However, if you choose not to use the Auto Discovery
option on startup, the servers' icons are white, indicating that there
is currently no information available for these servers. In this case,
you need to double click each server and enter the appropriate monitoring
password. You can also choose File > Login. Once the password is entered
for a server, Sun StorEdge Configuration Service begins the discovery process to
perform an inventory on the selected server. NOTE: If you need a very secure environment where access to
server inventory data is restricted, select No for Auto Discovery.
