1) Select 'No Storage' [workspace 3, display 1, browser tab 'TapeServer']
If already in 'No Storage' mode please ignore this step
2) STOP DAQ [workspace 2, display 1, browser tab 'Run Control']
all FEE64s should change status from 'going' to 'stopped' *except* whichever FEE64(s) have a problem - typically their status is 'going' or 'error'
3) Restart Merger by selecting the Merger icon [workspace 3, display 2]
terminal window showing the startup will popup
4) Setup Merger by selecting 'SETUP' [workspace 3, display 1, browser tab 'NewMerger Control']
5) Start Merger by selecting 'GO' [workspace 3, display 1, browser tab 'NewMerger Control']
all data links will be inactive (red)
6) Start DAQ by selecting 'GO' [workspace 2, display 1, browser tab 'Run Control']
check that DAQ is *actually* going - if not repeat 'GO'
7) Check data is being transferred to Merger and TapeServer
Select 'Reload' [workspace 3, display 1, browser tab 'NewMerger Control']
you should see a non-zero 'current merged data rate' and all links should show as green at least some of the time (requires observation over several reloads)
Select 'Reload' [workspace 3, display 1, browser tab 'TapeServer']
you should see 'Blocks written' and 'kb written' counters increase
8) Check AIDA data is being forwarded from the TapeServer to MBS [workspace 3, display 2, command terminal]
9) Unselect 'No Storage' [workspace 3, display 1, browser tab 'TapeServer']
If already in 'No Storage' mode at the start of this procedure please ignore this step
