Tuesday 13th May 2014 Maintenance Summary
RFM DMA setting [WP 4625]
I modified all models running on h1susex, h1seiex, h1susey and h1seiey to add the "rfm_dma=1" setting in their CDS block. The models on these front ends were restarted following the procedure:
stop user models, restart IOP model, start user models
Initial results suggest the ISC to LSC IPC error rate is slightly worse if anything.
I had some problems modifying the h1isietmx.mdl file. It was locally modified and also modified in the repository. The local changes appear to be purely because the model was saved using matlab2011a (presumably during the network outage). I resaved the local version with matlab2012b. Then I checked out the repo version in my home directory and diff'ed the two files. They did not differ by any significant factors. So I reverted the h1 model, applied the dma changes and compiled.
DAQ Reconfigure
The DAQ was reconfigured due to:
The DAQ was restarted at 11:49 and 14:06PDT to support these changes.
h1asc
Some time ago I worked on the compile error of h1asc to add ADS components. At the time I had performed a "make install-h1asc" but we were not ready to start the new model.
today after the first DAQ restart h1asc went into 0x2000 DAQ status due to the modified INI file. I was able at 14:09PDT to restart the new h1asc model to return the DAQ synchronization.
The new model has receivers for the new ALS_ASC_LOCKIN_OSC_CLK RFM IPC parts (two per end station for OSC1 and OSC2). Of the four new IPC channels only one is working. The other three are maxed out on their receive errors (2048 per second). Investigation is continuing.
OS patching
I performed the usual set of OS patches on vulnerable machines. No reboots were necessary to apply the patches.
Restart Reports Covering This Work
All times local PDT.
