After some discussion with the SEI group, I made the following changes to the macro file naming at LHO to make both observatories identical and following the same standard (defined in T1300881)

Removed
opt/rtcds/userapps/release/isi/common/medm/*macro.txt
from the svn - these were originally put there in error by Joe Betzwieser. MEDM screens were not affected by that on either site.

Moved
hpi/h1/medm/hepi/hepi$(chamber)_overview_macro.txt
to 
hpi/h1/medm/hepitemplate/H1_hpi$(chamber)_overview_macro.txt

This makes the hpi macro file names and locations consistent between the two sites.
I updated the H1 site map, which was the only medm screens affected.

Moved
isi/h1/medm/{bsc/ham}isi/isi$(chamber)_overview_macro.txt
to
isi/h1/medm/{bsc/ham}isi/H1_isi$(chamber)_overview_macro.txt

This affected the following medm screens:
cds/h1/medm/SITEMAP.adl  (the main sitemap)  
isc/h1/medm/H1IFO_ALIGN.adl
ioo/h1/medm/H1IOO-MC.adl
ioo/h1/medm/IMC_CUST_OVERVIEW.adl
all of them were updated and checked in.



ODC screen work

updated 
hpi/common/medm/hepitemplate/HPI_CUST_CHAMBER_ODC.adl
isi/common/medm/bscisi/ISI_CUST_CHAMBER_ODC.adl
isi/common/medm/hamisi/ISI_CUST_CHAMBER_ODC.adl
as well as the sys/common/medm/SYS_CUST_ODC*.adl files
to include the ODC mask and a link to the corresponding subsystem medm screen.
those files were also propagated to LLO, and the links now seem to work for both sites.

Next: same thing for SUS
