Display Correlations Between the Drives and Media with the Most Errors

Determine if there is a correlation between the drives and media with the most errors. This may help identify problematic drives and media.

Identify drives and media with the most errors to address the questions, "Which drives and media have had the most errors in the last 30 days? Are there any correlations between the two?"

1. In the left navigation, expand Tape System Activity, select Exchanges Overview.
2. Filter the data to display only those exchanges within the last 30 days and that involve the drive with the most errors (identified in Identify Drives With the Most Errors).
   1. Click Filter Data .
   2. Select Match ALL entered criteria.
   3. Add the filter criteria:
      • Exchange Start (Dates), Is After, a date 30 days ago
      • Drive Serial Number, Is, serial number of the drive with the most errors
   4. Click Apply.
      
3. To focus on the media involved in the errors, sort the table by a related column (such as Media Exchange Status, Exchange FSC, or Media Health Indicator).
   
4. Look at the Volume Serial Number column to see if there are any correlations between drive errors and specific media.
5. If you do find a potential correlation, filter the data further to display just the exchanges that involve both the faulty drive and the suspect media.
   1. Click Filter Data .
   2. Leave the current criteria rows as is, but add:
      • Volume Serial Number | Is | volser of the suspect media

      
   3. Click Apply.
