An EVSVR DatabaseReferences Repair Operation using Item Lists may not recreate unreference records for item found within a Collection
Article ID: 100034023

Description
Workaround
The EVSVR DatabaseReferences Repair operation can be done without using Item Lists
Cause
When using Item Lists, the EVSVR Verify operation will create an Item Lists which will be then used as an input file for the repair.
The EVSVR DatabaseReferences operation in Verify mode does not provide any option to configure Check Collection Count, and the EVSVR operation is executed with the setting enabled.
As a result, collections containing unreferenced items whose count is equal to the difference of Total Count of Items and Reference Count of the Collection (unreferenced count = Totalcount - Refcount) will not be added to the Item Lists. When the repair is then performed, disabling the Check Collection Count option will have no effect as the Item Lists file only contain collections with a mismatch count
Resolution
This issue has been addressed in the following release:
Enterprise Vault 12.2
Enterprise Vault 12.2
Issue/Introduction
When an item which is collected is deleted, the DVS file is not immediately removed from the cab file or EMC Centera Clip, but instead the number of referenced files within the collection is reduced.
During an EVSVR DatabaseReferences operation in Repair mode, the Check Collection Count option (which is enabled by default) is used to prevent records which could have been legitimately deleted from being recreated in the database. After a collection has been scanned by EVSVR, the count of savesets identified with no references in the associated Enterprise Vault (EV) VaultStore database will be compared to the difference of the Total count of files within the collection and actual number of reference files for that collection (Totalcount - Refcount).
If the difference is equal to the number of unreferenced collected items identified within the cab file, EVSVR assumed that the files were legitimately deleted.
To recreate all collected, and unreferenced saveset records, The 'Check Collection Count' option is unchecked. Unreferenced record will from being re-inserted if “require index entries” is set.
When using Item Lists with the DatabaseReferences operation, and Check Collection Count is unchecked, items may still not be recreated as expected
