Here is today's summary of NHC computer operations:
--- Craig Mattocks

----------

TAFB:
1. The N-AWIPS workstation Grunt crashed during an NMAP session twice -  
first when SOO Chris Landsea was attempting to edit the Pacific Sea State  
graphic, and second when clicking on the icon to access the  
distance-measurement tool. Chris switched to using the Shiner workstation  
to compose the product. TSB N-AWIPS expert Matt Sardi called and advised  
Chris to reboot Grunt as soon as possible.
HSU:
1. The ASCAT-B scatterometer winds were missing yesterday from N-AWIPS  
because the processing was being run on Sr. Hurricane Specialist Mike  
Brennan's desktop workstation (pinfish). TSB Developer Matt Sardi has  
migrated the ingest and processing to one of NHC's primary compute servers  
(nhc-lx-comp03), which will eventually be mirrored to the other compute  
server (nhc-lx-comp01). The data are now populating to both the /ldm1 and  
/ldm2/decoders/ascatb_25km* directories on NHC's NetApp (network mounted  
storage) for access in N-AWIPS. Meanwhile, NCO SysAdmin Brian Maher has  
determined that, as suspected from the "Input/output error" messages on the  
Linux terminal screen, the hard disk on pinfish was damaged/corrupted. He  
has backed up and is replacing the hard disk on the workstation.

2. Update on double/triple plotting of buoy data in N-AWIPS. TSB Web  
Developer Dave Zelinsky has been investigating and consulting with NCO and  
the other National Centers on this issue. One suggestion was to set the  
filter under "edit source" to 0.01 (the smallest possible value). This  
doesn't remove any real obs, but was suppose to get rid of the duplicates.  
However, even though OPC is using such a filter, they still suffer from the  
same double/tripple plotting problem, so this appears to be an N-AWIPS  
decoder issue. OPC will contact NCO/SDB on NHC's behalf to address the  
problem. The filter doesn't show the newest data, but rather shows a single  
observation that remains in place until it times out. Therefore, when there  
are multiple records, you see the first observation, not the latest  
(desired) observation.

3. Sr. Hurricane Specialist Richard Pasch's new Lagrangian “adrift" buoy  
(42057) is gradually streaming northwest towards the Yucatan Channel:

Other items:
1. Due to an ongoing NetApp slowdown issue and the queues filling up on  
NCO's ncodf9 DBNet server, the Himawari satellite data stream has been  
temporarily reduced to channel B13 only.
