Unable to retrieve item due to Attachment Metadata stream for SISPart's is missing from DVS

Problem

Unable to retrieve item due to Attachment Metadata streams for SISPart's is missing from DVS. Affected items are not indexed as storage crawler fails to retrieve the item leading to items missing from indexing.

Error Message

EVSVR DumpSaveset log shows:
Getting recombined Saveset (DVS) file.
Event Output: Unable to complete retrieval request
Reason: could not be found.(0x80030002)

Dtrace of EVSVR shows:
{CSavesetOnIStg2::OpenAttachmentMetadata:#558} _com_error exception: [%1 could not be found.  (0x80030002)]

Cause

DVS files for which the SisPartMap indicates a SIS part has been removed for a particular attachment, however the attachment metadata for that attachment is missing from the saveset. This causes retrieval to fail, including for indexing, and EVSVR DumpSaveset could not get the recombined Saveset.
