Issues associated with initial data collection
For initial data collection, the following potential issues can be seen in SLP reports due to the EMM behavior.
Since initial data collection loads all the data from the EMM, it may have an image entry with missing copy entries. It is possible that the copy entries in the EMM worklist are deleted due to the following factors:
If the Retention type of an SLP destination is Expire after Copy or Fixed.
If duplications happen on a tape drive
The deletion of copies has the following affect on the data that is shown in specific SLP reports:
The SLP Duplication Progress report is in a bar chart format. The X axis shows all duplication destinations associated with the SLP; Y1 axis bar charts show the percentage of images completed (% Images Count) and Y2 axis shows how many images are actually created (Completed Images Count).
If a backup copy is deleted from the EMM worklist, then this report may show that the backup copy count is less than the duplication count. This is misleading. It is expected that when an SLP is complete, same number of copies should be created on all the destinations. Similarly the % Size Completed computation is inaccurate for this report.
If a backup copy entry is deleted from the EMM worklist, the SLP Duplication Progress report will not show the backup bar chart. Similarly, if a duplication copy entry is deleted, the Duplication Progress report will not show the duplication bar chart.
The SLP Status by Destination report will show incorrect copy sizes across destinations. The following columns of the SLP Status by Destination report show incorrect data:
Total Expected Size - all copies (MB)
Completed Copy Size (MB)
