Media Management Cleaning Media Report

Use this report to check the average usage of cleaning media libraries as well as the cleaning media detail per library for the selected CommCell(s). Running this report can help detect issues with the drives and or cleaning media, e.g., if cleaning media averages are consistently high for a specific library, this may indicate that there is an issue with the library's associated drives.

The following details are provided in this report:

Cleaning Media Library Usage

• Library Name
  The name of the cleaning media library.
• Total Number of Media
  The total number of cleaning media associated with the library.
• Total Number of Used Media
  The total number of cleaning media used within the library.
• Average Usage
  The average usage of the library's cleaning media. This average is calculated by the following, the Total Usage number divided by the Total Number of Media. For example, a library can have 10 cleaning media associated with it, with a total usage of 40. The average usage for the cleaning media within this library is 4. Note that expired media are included in average usage calculations.
• Total Usage
  The total number of times cleaning media have been used within the library. 

Cleaning Media Detail

• Library Name
  The name of the library associated with the selected cleaning medium.
• Barcode
  The Barcode given to the selected cleaning medium.
• Creation Time
  The selected cleaning medium's time of discovery.
• Expired
  Indicates whether the selected cleaning medium is expired, i.e., exceeded its usage threshold. Note that expired media is included in usage average calculations.
• Number of Uses
  The number of times the selected cleaning medium has been used.
• Threshold
  The threshold for number of uses, which can be viewed and modified from the Drive Cleaning tab of the Hardware Maintenance Thresholds dialog box in the CommCell Console.
• Average Usage
  The average usage of the cleaning medium (14-day basis). This average is calculated by the following, the total usage for the selected time range divided by the number of 14-day intervals that have passed within the selected time range. For example, a cleaning medium was created (discovered) on January 1, 2008, and a cleaning media report is run on January 30th, with a selected time range of the last 30 days. The average usage will be calculated as follows:
  • During the first-week period, January 1st - 7th (7 days), the selected cleaning medium was used 9 times.
  • During the second-week period, January 8th - 14th (7 days), the selected cleaning medium was used 3 times.

  Total usage for this 14-day period is 12.

  • During the third-week period, January 15th - 21st (7 days), the selected cleaning medium was used 7 times.
  • During the fourth-week period, January 22nd - 28th (7 days), the selected cleaning medium was used 3 times.

  Total usage for this 14-day period is 10.

  • During the fifth-week period, January 29th - January 30th (2 days), the selected cleaning medium was used 2 times.

  Total usage for this period is 2. (Though this is not a completed 14-day period, it will still be counted as a 14-day interval for the purposes of calculating usage average.)
  With this, we can determine, that within the 30 days, the selected cleaning medium has been used a total of 24 times. To calculate the average, we divide the total usage for the selected time range by the number of 14-day intervals, in this case, 3. The average usage for this cleaning medium is 8.

NOTES

Usage average calculations include expired media, but do not include deleted media.
