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.

added the following sus tags (as requested by Betsy)
X1 SUS QUAD
X1 SUS BS/FM
X1 SUS HSTS
X1 SUS HLTS

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?

The drawing of the LHO test stands in the staging building
and the OSB can be found in the following DCC document:

Ben rack mounted a X4270 unit immediately above the X2200 systems (nds, etc.)
This will become the test frame writer/QFS machine and will run sol10.

In keeping with the X1 SYS SUB alog tag convention,
the DTS is now tagged "X1 DAQ DTS"

In consultation with Hugh, we decided to change the keyword "X1 seiteststand" with 
a more accurate "X1 SEI HAM ISI" for the current work going on in the staging
building.

The logbook Shibboleth SP has been configured to behave like a wiki.  This extends the session time such that users will not need to roundtrip to the IdP longer, and helps with POST requests that might be made across a session boundary.

I am also using this entry to test the L-mail feature.
