Enterprise Vault (EV) archived items migrated to a NetApp AltaVault device cannot be retrieved

When EV Collection (Cabinet) files have been migrated to a NetApp AltaVault device the items can no longer be retrieved. The user receives a message stating that the item is no longer in the vault.

Cause

This is due to the NetApp AltaVault device being a case sensitive device. When cabinet files are created on an Enterprise Vault partition they are created with the file extension .CAB in an upper case format. Enterprise Vault is not a case sensitive application and in this instance the request to obtain the cabinet file is initiated with the cabinet file extension in a lower case format. The Alta Vault device does not accept this request and the file not found is the given response.

Solution

This issue has been addressed in the following release:
