Report Trends in Drive Error Rates

This procedure addresses the questions, “Which drives have had the most errors this week? Have their error rates gone up?”

Although STA screens show 30 days worth of data by default, you can use filter and selection criteria to narrow down to just the current week. The following methods are described:

•
“Using the Drives – Overview Screen”, below
•
“Using the Libraries – Exchanges Screen”
•
“Using the Notifications – Overview Screen”

Referenced Tasks

•

•
“Add Library Resources to Graphs”
•
“Change the Date Range”
•
“Move a Column”
•
“Hide and Reveal Columns”
•
“Use the Filter Data Dialog Box to Change a Table Filter”

2.
In the “Device Serial Number” column, click the Sort Ascending or Sort Descending arrow.
