9 Monitoring
This section describes the various tools you can use to monitor the status of the VLS hardware and virtual
devices (libraries and tape drives), and how to use them. These monitoring tools include:
• Status information in the Status pane
• Status icons
• Notification alerts
• Trace log files
Status information in the status pane
Status information for the VLS hardware components and virtual devices is displayed in Command
View VLS on the status pane when an individual hardware component or virtual device is selected
in the navigation tree.
The five device status possibilities are:
•
Good— The component, part of the component, or the virtual device is operating normally.
•
Degraded—The component, or one or more parts of the component, has failed or is operating
outside of its normal range but is still operational.
•
Critical —The component, or one or more parts of the component, has failed or exceeded its limits.
Although it is still operational, VLS failure is imminent.
•
Failed—The component, or one or more parts of the component, has failed and the VLS is inoperable.
Immediate service is needed.
•
Missing —The VLS cannot detect the component or a part of the component.
In addition to the device status, a red or yellow alert bar will highlight specific parts of a component
when that particular element within the component has failed (red) or is operating outside its normal
range (yellow).
To view the status information for a VLS hardware component or virtual device:
1.

in the status pane.
Status icons
