Monitoring

The main SANscape window provides status at a glance for all networked array devices. It indicates the status of the devices and logical drives connected to servers monitored by the SANscape Console. The devices include host adapters, array controllers, disk storage enclosures, physical disk drives and other SCSI devices.

The window’s tree structure offers detail for all devices connected to each server. The container symbol at the left side of the tree indicates whether the display of devices is expanded or collapsed. The container symbol means that you can click to display more devices. The container symbol indicates that all devices at and below that level are shown.

Event Logs

The SANscape console receives, logs and displays events generated by managed servers and by the SANscape console itself. Most events are generated by the SANscape Agents on the managed servers and occur when there are:

￿￿Status changes on any device on a managed server, including the server itself

￿￿Inventory changes such as the addition or removal of devices

￿￿Configuration changes including initial configuration setup and subsequent changes

￿￿Array processes running such as initialization, parity checking and rebuilding

Although the SANscape console initiates array processes, it is the server agent that generates operation notification events after these processes start on the server. The SANscape console generates a much smaller number of events. For example, it generates an event if it does not receive a certain number of consecutive heartbeats from a managed server.
