5. Connecting and Disconnecting from a Disk Array
One benefit of Event Monitor is that the program can be installed as a permanent window on array status.  Before system monitoring can be performed on a particular disk array system, you need to first establish the connection between your management station and the Primary Agent host.  Once the connection is established successfully, system events can be displayed.

All the arrays controlled by a Primary Agent server, as each is a controller communicating through a Secondary agent, appear on the Connection View window.

There is only one controller icon for disk arrays using redundant controller configuration.  Controller configuration is synchronized between two controllers and these two controllers appear to the host as one controller.

Disconnection is used for breaking the link between the Event Monitor station and the array.  Normally, all the arrays should be selected and all it takes to switch around multiple disk arrays is but a single mouse click -- instead of restarting the Event Monitor every time you need to switch to another system.

The following discusses how to connect to a disk array.

(Note that monitoring actually begins when Primary and Secondary Agents are started (or restarted).  Event Monitor displays all events recorded by the Agents, regardless of whether or not it was running at the time of the event.)


Connecting to a RAID system while working from the local Primary Agent host:

 

1.  From the Connect menu, select Open.  Repeat this process to select all the Primary Agent hosts.

 Click the Default button.

2.  Select the IP address of the RAID you would like to monitor or manage from the Connection View list.  Double click the IP address.  Double click the controller icon.  Double click the connection method (e.g., In-Band SCSI).

3.  The connection is successful when the list of events appears and the Physical view and logical unit subtrees appear in the navigation panel.


Connecting to a RAID system from a distant host:

1.  From the Connect menu, select Open.  Repeat this process to select all the Primary Agent hosts.

2.  Select the IP address of the RAID you would like to monitor from the Connection View list.  Choose and double click on an IP address.  Double click the controller icon for that IP address.  Choose and double click the connection method (e.g., In-Band SCSI).

3.  The connection is successful when the list of events appears and the Physical view and Logical unit subtrees appear in the navigation panel.


Disconnecting from a disk array system:

Select an IP address by single mouse click.  From the Connect menu, select Close.  This method will disconnect with the host computer represented by its IP address.  If the host is a Primary Agent server, this will discontinue the connection to all the RAID systems managed by it.

The subtree representing the RAID system immediately disappears from the navigation panel once disconnected.

 


Display Controls

Just like RAIDWatch Manager, Event Monitor works entirely with windows, buttons, and icons to facilitate the display of various disk array conditions.  These windows follow the standard Windows and Unix OS “Look and Feel” specifications, thus steps for manipulating elements and windows within any Event Monitor window generally conform to standard procedures.
