The past 6 months of raw minute trend were archived on TW0 and the NDS process on h1daqnds0 was restarted to serve these data from this temporary location while the transfer is ongoing.

The copy of these files from TW0 SSD-RAID to permanent HDD-RAID storage on h1ldasgw0 was started at 09:39 PDT. As of 13:26 PDT, 37 of the 256 directories had been copied. This gives an ETA of Wed 19th 11:50 PDT.

Replacement of broken Pulizzi power control unit

Ryan S, Dave, Erik:

Ryan discovered that pwr-cer-pem0 Pulizzi unit which powers the PEM magnetic coil located in the inner cleaning room (between gowning and LVEA, on the wall it shares with the CER) was unresponsive with an error message "Error: telnet to host pwr-cer-pem0 fail". This was a strange failure in that the unit was not pingable or telnetable, but the sw-lvea-aux port it was attached to was not reporting a comm error. Ryan compared this Pulizzi with a working one an nothing suggested it had failed.

Trending back this unit could have failed mid-May, 14th May was the last time it ran successfully.

Erik replaced this unit with a good spare. Ryan is looking to modify the magnetic injection script to verify correct Pulizzi control.

DAQ Restart

Jonathan, Dave:

The DAQ was restarted for the DMT change. This was unremarkable other than gds0 needing a second restart.
