How to copy raw data files from tape
(email from Brad Sawatzky) Do not use 'jget' -- that makes a copy to an arbitrary file system (kind of like 'cp' on regular files).
You want to use 'jcache get ...' which will have the system pull the file to /cache/hallc/spring17/raw/ as you wish. Run 'jcache -h' to get some help text and/or the online docs here: https://scicomp.jlab.org/docs/%20
So, something like this should work: jcache get /mss/hallc/spring17/raw/shms_all_02895.dat The file will show up here as soon as a tape drive is ready to pull the run (can be anywhere from minutes to 24 hours depending on load). /cache/hallc/spring17/raw/shms_all_02895.dat
Wildcards work too: jcache get /mss/hallc/spring17/raw/shms_all_028*.dat (But be careful, don't do 'jcache get /mss/hallc/spring17/raw/*' :-)
You can find the status of your request from: https://scicomp.jlab.org/scicomp/index.html#/cache/request
Example for PREX counting daq data:
ifarm1402.jlab.org> jcache get /mss/halla/happexsp/raw/prexRHRS_20982.dat.0 get request: 21382881 status: pending /cache/halla/happexsp/raw/prexRHRS_20982.dat.0 -> pending
