FGT OPS manual

 This is cover page for  the future FGT OPS manual for year 2012

A)  HV control - Instructions:

1) Login to gateway: ssh rssh.rhic.bnl.gov -l [username] -X

2) Login to rcf2: ssh rcf2.rhic.bnl.gov -l [username] -X

3) Login to fgt-ops:    ssh fgt-ops.starp.bnl.gov -l fgttester -X    (needs password)

4) cd snmp

5) run_display

B)  Reprograming of FGT ARC (electronics)

1) from rcf2:   ssh operator@daqman.starp.bnl.gov   (needs password)

2) cd /RTS/GERARD/ARC_support

3) execute  REPROGRAM

C)  Dumping FGT ARC register values to file

1) from rcf2:   ssh operator@daqman.starp.bnl.gov   (needs password)

2) cd corliss/FgtArc_20120215

3) execute  read_both >> filename (where 'filename' is the log file of choice.  This is very fast.)

3a) repeat the above to different filenames before and after stopping the run, as requested

4) transfer back to rcf or wherever you like with scp

D)  FGT Gas Supply

1) All adjustments on the gas flow control panel on the STAR detector are done by experts only.

2) The manual for monitoring the FGT Gas Supply by the Detector Operators is found here.

E)  Changing latency of APVS  (expert only)

 edit /RTS/con/fgt/fgt_rdo_tune.txt in daqman as operator 

 start new run - nothing needs to be uploaded

 

 

F)  FGT QA Monitoring / Shift crew instructions (defined by Bernd)

FGT group schedule Run 12 (500GeV) 

1) Location of FGT QA (XLS-file / Numbers-file / pdf-file)

2) Procedure:

a) Download above file (XLS or Numbers) and add your QA information

b) Consult shift summary and only use 'good runs' for QA

c) Check shift log for entries indicating FGT problems and write in spread sheet 

Step 1) J-PLOTS QA: Look at JPlots for runs where FGT events are present (Use shift summary or FGT status) 

          Reference 1 (Until 03/19/2012)

          Reference 2 (03/19/2012 - NOW)

Use 0 / 1 to mark no change and change compared to reference plot. In case of change, add note using spread sheet function and send

email to FGT list.

Step 2) Slow control QA: Check database plots 

           then click on -> Conditions_fgt

          2a)  First  ->  FGT Gas System  ->  DISPLAY SELECTED CHANNELS  ->  Click Here  ->  adjust X, Y axis parameters,

           then  ->  DISPLAY!    Also can adjust size of plot with [+] or [-] zoom buttons.

           Reference plot 

2b)  Next  ->  FGT Board Voltages  ->  FGT Board Voltages - measured, uX or u10X or u20X

           ->  DISPLAY SELECTED CHANNELS  -> Click Here  ->  etc. as above. 

           Reference plot

          2c)  Then  ->  FGT Board Currents  ->  FGT Board Currents - measured, uX or u10X or u20x

          ->  DISPLAY SELECTED CHANNELS  ->  Click Here  ->  etc. as above.

          Probably use  "Y Axis LOW" = .0002 and "Y Axis HIGH" = .0004 to view the currents.

          Reference plot

          Use 0 / 1 to mark no change and change compared to reference plot. In case of change, add note using spread sheet function and send email

          to FGT list.

 

 

Not implemented yet!

4)  Check pedestals  (http://www.star.bnl.gov/protected/spin/rfatemi/FGT/fgt_status_time.gif)

      *** need example plot showing good / bad condition ***

5)  Record problems found  *** how / where ***

      *** need names of people to contact if there are problems found during the QA ***

      When complete for the day, record your name and date *** where ***

JANs sub-page for FGT ops

 JAN: this page was created after Jerome opened write privileges

RENEE : I am writing on Jan's child page

Renee's Child Page

Is it this easy to have a child?

at the beginningyes, with time it gets more serious responsibility, but parents mature in sync (or not), Jan

HPSS I/O

 

 

HTAR :  save/restore  private directory (large set of small files) in HPSS

For saving all files in directory 'aaa' on disk to your HPSS target bbb/ccc.tar and keep log file in ~/0x/ddd.log1 (needed if you want to kill/quit the window) do: 
 
cd aaa
du -hs .
htar -cf bbb/ccc.tar file1 file2 fileX* ... >& ~/0x/ddd.log1 &
(wait until job is done, for 50GB make take severa hours)
hsi (goes directly to HPSS, be careful!)
?ls -l  bbb/
?quit (exit hsi)
 
You should see 2 files : ccc.tar & ccc.tar.idx, the size of file ccc.tar should be close to the size of your oryginal directory.
The .tar file shows up immediately but sinking is NOT finished until you see  .idx file.
The log file should contain the string: HTAR: HTAR SUCCESSFUL , no warnings.
However the most reliable way to verify the storage did not failed is to:
 
retrieving files from HPSS  to disk directory eee do:
 
mkdir eee
cd eee
htar -xf bbb/ccc.tar  >& ~/0x/ddd.log2 &
 
Other options of HTAR command are described here: 
       http://drupal.star.bnl.gov/STAR/comp/sofi/hpss/htar

Known problems:

WARNING: htar_PreallocateSpace: HPSS OUT-OF-SPACE error preallocating
**** bytes for file=[/home/salur/myfile.tar]
This is a directory with 350G. Do I have to divide my files into  smaller.
 there is a 60GB max file size limit [when creating tarballs],   Another
limit to be aware of, however, is an 8GB limit on member files
 

 

 Mass restoring of ~100GB files from HPSS using Data Carusel

Prepare input file xxx.hpss with list of source +destination paths for all files  you need, one line per file

Execute the command (at any location at rcas6nnn)

 hpss_user.pl -f xxx.hpss

Wait 10-1000 minutes fro the files to show up at your destination (if all paths are correct)

 

 

 

Instruction for new users uploading FGT documents

Instruction for remote uploading of documents to the common FGT Drupal place to complement missing features of fgt-hn

 

First time setup

  1. You need to login to drupal as you. The password is different than your regular RCF password. If you do not remember Drupal password select 'forgot password' and new one will be sent to you by e-mail
  2. got to the mother-web page:
    http://drupal.star.bnl.gov/STAR/subsys/upgr/fgt/hn-upload-contributions
    you can also navigate: SubSystems --> Detctor Upgrades --> FGT --> FGT-HN Upload
  3. Got to the bottom and select 'Add child page'
  4. Set the following fields:
    * Title: yourName-FGT-HN-Uploads (edit it)
    * Parent: ------FGT-HN-Upload contributions (selectable from menu)
    * STAR: --FGT (selectable)
    * Body: Your Name : list of attachements sent to FGT-HN (edit it, just 1 line)
    Upload a test jpg file using menu at the very bottom of the page. To attache new file, first 'Choose File', next 'Attach'
  5. Finally at the very bottom 'Submit' the whole page to Drupal.
  6. go to the 'mother-page' and you should see:
    * in the upper part your JPG
    * in the lower part (below bold text) your sub-page among other people who already joined, alphabetical order.
    If you can't see your contribution at this point contact me (Jan). Do not try it over - it will add mess to Drupal. If you add more than one page only the first one will be considered

 

Uploading subsequent documents

  1. Login to drupal and go to your sub-page with this test JPEG
  2. Click Edit
  3. scroll down to upload section and add as many documents as needed, one by one
  4. you may change the name of uploaded file - just edit it
  5. Click 'Submit'
  6. go to the 'mother-page' and you should see your new documents listed in chronological order.
  7. Now you can sent an e-mail to FGT-HN referring your new uploaded documents as: 
    .... new docs are uploaded to:
http://drupal.star.bnl.gov/STAR/subsys/upgr/fgt/hn-upload-contributions 
under myName, files xxx-yyy-jpg and zzz-uuu-mmm.pdf

Report to me if there are any problems,
Jan
