Thank you. I added:

       <index_order>hrDiskIODescr:hrDiskIOIndex</index_order>

to /usr/share/cacti/resource/snmp_queries/disk_io.xml, deleted the disk I/O
graphs for one host (I'm pretty sure I said to delete linked data sources),
and recreated disk I/O graphs for that host.

If I go to "Data Sources" for that host, the "Custom Data" section still
shows:

  Output Type ID      [Host MIB - Disk I/O - Bytes per second]
  Index Value         55
  Index Type          [hrDiskIOIndex]

but the Index Type is now a drop-down which would allow me to select
hrDiskIODescr if I wanted.  Should I change it to

  Index Value         md127
  Index Type          [hrDiskIODescr]  ?

And if so, how could I get this chosen by default for new graphs?

The systems are running now so I can't reboot to try to shuffle the OIDs
around.  However as far as I can tell, the new graph is working fine and the
old graphs are continuing to capture data.

I have 22 sets of I/O graphs in total, so it would be nice if I could avoid
deleting and recreating them all.

Cheers,

Brian.
