Report Drives With the Most Errors

1.
In the Navigation Bar, select Drives > Overview.

2.
In the Templates menu, apply the “STA-Drive-Health” template.

3.
In the “Drive Errors (30 Days)” column, click the Sort Descending arrow.

The drives with the most errors are brought to the top of the list.

4.
Use the following steps to add selected drives to the graphs.

Adding the drives to the graphs allows you to compare their attribute values against the system average. By default, graphs always include the system average.

a.
In the List View table, select the drives you want to add to the graphs.
b.
Click the Apply Selection icon on the Table Toolbar.

The graphs are updated with the drive data. In the example below, one of the drives shows a high level of errors when compared with the system average.

Report Media With the Most Errors

1.
In the Navigation Bar, select Media > Overview.

2.
In the Templates menu, apply the “STA-Media-Health” template.

3.
In the “Dismounts With Errors (30 Days)” column, click the Sort Descending arrow.

The media with the most errors are brought to the top of the list.

4.
Use the following steps to add selected media to the graphs.

Adding the media to the graphs allows you to easily compare their attribute values against the system average. By default, graphs always include the system average.

a.
In the List View table, select the media you want to add to the graphs.
b.
Click the Apply Selection icon on the Table Toolbar.

The graphs are updated with the media data. In the example below, both media show high numbers of errors when compared with the system average.

Display Correlations Between the Two

This procedure helps you to determine whether there are correlations between the drives and media with most errors. The Libraries – Exchanges screen is the most useful for this activity because each exchange involves exactly one drive and one piece of media.

1.
In the Navigation Bar, select Libraries > Exchanges.

2.
Use the following steps to display only those exchanges that took place within the last 30 days and that involve the drive with the most errors.

The drive with the most errors was identified in “Report Drives With the Most Errors”.

a.
Click Filter Data.
b.
Complete the Filter Data dialog box as follows:
•
In the “Filter Matching” field, select “Match ALL entered criteria”.
•
In the “Exchange Start” field, select “Is After” and enter a date 30 days ago.
•
In the “Drive Serial Number” field, select “Is” and enter the serial number of the drive with the most errors.
c.
Click Apply.

The table is updated according to your selection criteria.

3.
To focus on the media involved in the errors, sort the table by a related column.

Suggested columns are “Media Exchange Status”, “Exchange FSC”, or “Media Health Indicator”.

4.
Visually scan the Volume Serial Number field to see if there are any correlations between drive errors and specific media.
5.
If you do find a potential correlation, use the following steps to filter the data further to display just the exchanges that involve both the faulty drive and the suspect media.
a.
Click Filter Data.

The selection criteria already in effect are displayed in the Filter Data dialog box.

b.
Complete the Filter Data dialog box as follows:
•
Leave the current selection criteria as is.
•
In the “Volume Serial Number” field, select “Is” and enter the volser of the suspect media identified in Step 4.
c.
Click Apply.

The table is updated according to your selection criteria.
