Hi Mark,
I am new to this site, and so I am struggling to figure out how to add an attachment. Sorry!
I just figured it out, and have made edits to this thread since then.
In the helpbefore.out file, there is the DDL for the table partition audit_event and output from sp_help audit_event. In this output, you can see the table partitions belong to the various segments that span across multiple devices. At this point, the audit_event table/partition has no indexes defined. In the helpafter.out file, there is the DDL for the indexes on the audit_event table, and output from sp_help audit_event. In this output, you can see the table partitions now belonging to the segment that is assigned to the indexes - index_infraseg.
However, if you look at the index DDL, you can see that I was specifying the segment name prior to the local index partition clause. So, you will see an extra "ON index_infraseg" before the local index statement. I'm wondering if this is the culprit. I am going to remove that statement and try again. I'll post shortly my results. Thank you so much for your assistance.
