It has been shown there have been issues with our H3 GS-13.  Before pulling out the GS-13, the ISI table was visually checked for mechanical shorts (none were found).  As another system/pod check, the ISI table was tilted in a couple of different states(by placing weight on table) such that the pod would be angled "down" & angled "up".

H3 is unique in that it is the GS13 whose axis is perpendicular to the Support Tubes (vs. H1 & H2 who are symmetrically angled wrt the Support Tubes).  For our set up, the "crane-Southern" Support Tube is the side where the "TOP & unfixed" end of the H3 GS13 is.  The "crane-northern" end of the GS13 is where the "BOTTOM & bolted-down" end of the GS13 is.  Because of this geometry, it was easy to put weight on the table such that we tilt the TOP or BOTTOM of the GS13.

With the TOP tilted down, we did not notice any change in the H3 performance (we were looking at DataViewer, the signal looked noisy, and would only show big seismic bumps and then quickly damp that out, and return to the noisy state).  

With the BOTTOM tilted down, H3's performance totally changed---for the better.  H3's signal looked like its fellow H1 & H2.  A Power Spectrum confirmed that H3 looked like the other GS13s when the BOTTOM was tilted down.  The attachment's top plot shows the GS13s with the ISI weight down on the Northern end of the table.  The bottom plot shows a balanced & unlocked ISI from last week (where we had an ugly H3).

After this, we decided to swap this GS13 for our one & only extra Horizontal GS13.  For documentation, there is a Serial Number on the base flanges for these guys.  

Original/old H3 GS13 is S/N 046
New H3 GS13 is S/N 068

Will post performance of our new H3 after the swap is made (not a trivial or quick task).

Removed entries for awg and tp from /opt/rtcds/geo/g1/target/gds/param/diag_T.conf file as general cleanup.  The lines were unneeded for description of awg and tp services, the awg and tp services are established and registered with diagconfd when awgtpman is started from the startup_g1x01.cmd and startup_g1isiham.cmd scripts.  Any awg or tp entries in the diag_T.conf file would be at best duplicates.

Jonathan wrote a cronjob on alog to create two backup files daily: sql dump file
of the text content and compressed tar file of the graphical files.

I just wrote a cronjob, which runs on control100 within CDS, to scp these files
into /data/backup/alog every morning at 05:30. From there they are rsynced to 
the CDS backup disk, and then written to tape.

This backup scheme will be replaced with rsync later because the graphical file will
get very large very quickly.

The H2 DAQ rack is a new style (beige) rack located in the MSR nearest
the hallway. It has two Sun X4270 computers, which will be the H2 DAQ
frame writers/QFS masters.

Cyrus is working on installing sol10 on these systems. He will also test the
DAQ networking switches and spare units using this rack.

We encountered a problem with the rack mount KVM switch in this rack, the internal
power connector to the PCB is flakey. The flatscreen monitor signals this with
a "cable not connected" error and powers itself down.

The electronics test racks for seismic testing at LLO are through the initial setup and checkout.  
There are two racks. 
   llosei1 - HAM-ISI testing
   llosei2 - Seismometer huddle testing
David Kinzel assembled the racks, installing the equipment shipped from Pasadena and Hanford.
Keith and Rolf got the front-end computers set up.
Ben and Sam Abbott were here this week to do the electronics checkout with the initial models.

The test racks are presently on the CDS network, but are reachable from outside at
 llosei1 - llocds.ligo-la.caltech.edu  Port 9001   (DNS name dts1 within llocds)
 llosei2 - llocds.ligo-la.caltech.edu  Port 9002   (DNS name dts2 within llocds)

* We clearly need some X2 tasks added

Today, dtt was used to obtain spectra for the LHO HAM ISI Assy #1 located at the SEI Test Stand.  This measurement was run with the dial indicators disconnected.  Two measurements were run:  The first one ("T1") had H1V1H2V2 Displancement Sensors & ALL GS13's.  The second measurement ("T2"), had H3V3 Displacement Sensors.  Two measurements were needed because of the ~0.3Hz noise seen between both Displacement Sensor "mini-racks".

One blaring feature (see attached spectra) is the H3 GS13---something looks amiss with it.  Checked the rack for anything obviously wrong, but all HAM Interface Chasis looked fine.

Vincent suggested putting a 300count vertical offset on the H3 Actuator, and this clearly showed something wrong with this GS13 (see attached screenshot).

The attached image shows the the contrast defect from using the phase map of one of the AdvLIGO optics. The file name is 's1tins'.

Installation work on the new solaris frame writer (dtsfw1, X4270):

Used LSI bios to build RAID1 mirror on the two boot disks (called IM)

Installed sol10 from external DVD unit, using ZFS for the boot disk.

Created a controls account.

Installed Sun Stu-stu-studio 12.1 in /opt/SunStudio, controls account path
set to find these binaries.

Quick test, compiled a "hello world" C file.

Note: /cvs does not want to mount on reboot, so at the moment I'm logging in
as root and manually mounting it.

Fired up the DTS X4270 last night and like the one in the MSR
it didn't boot solaris, rather gave a "bad PBR" error and then
went into PXE boot search mode. This is the Primary Boot Record
so does this mean solaris was not pre-installed?
