PEB_hallavme12pc

  • script that launches coda_emu_peb. restarts it when it is killed.

ROC_hallavme14pc

  • script that uses remote_vme to launch SBS_startroc.sh on hallavme14pc

ROC_sbsvme25

  • script that uses remote_vme to launch SBS_startroc.sh on sbsvme25

SBS_startroc.sh

  • script on sbsvme25, hallavme14pc that launches coda_roc with a ROC name determined from it's hostname.

kill_remotes.sh

  • Use same mount scripts used on hallavme12pc
  • Use local storage for data.

Add SSP crate

  • Figure out it's hostname
  • Get it to boot just like the other ROCs
  • Check TI
  • Check SSP
  • Check MPD (for checking/debugging APVs)
  • Tell Ben we're ready to start connecting fiber from MPD to SSP

Log CODA runs to logbooks/superbigbite

  • check out code used by Hall A's CODA 2.x
  • from Alex:
- epicsRunstart
- epicsRunEnd
- runstart.tcl
- runend.tcl

Add scripts and GEM-cleanroom specific configuration files to a remote git repo
