> During testing for the S452 experiment yesterday we were running through the steps of a restart. > > The FEEs were not powercycled at this stage but the MIDAS server was restarted. > Initial setup went smoothly and no issues were encountered during setup. > NewMerger and TapeServer were both setup and set to going. > Upon ''Going'' the run control the data transfer for aida09 dropped out. > Going to the NewMerger it could be seen that data was making it through and data items were being merged. > The tapeserver however was seeing no data and neither was the MBS dataspy. > During this time the FEEs became unresponsive likely as their buffers filled. Trying to reset gave the attached errors. > > Checking the folder manually it could be seen that the Options file was there. > > At this point a powercycle was pewrformed but upong 'Going' the DAQ the same issue was again encountered. > > This time we were able to recover control access to the FEEs by running multiple NewMerger sessions which helped clear the buffers. > > During our search for the problem we looked at the Options from within MIDAS and could not see anything out of the ordinary. > We also tried restoring the Options from within MIDAS. > We again reached the same issue with the tapeserver. > > At this point we restored the Options folder from by copying manually within terminal. > Following this we were able to start the DAQ normally.
