Changing the Data Storage Convention

The file/data/opt/etc/rc.FY2 has a setting that controls the little-endian/big-endian convention for files. SSEC sets the default to little-endian convention, but includes a pair of lines in rc.FY2 that can be edited to change the setting to big-endian convention.

The lines should remain as is (both commented out because they begin with a # symbol) unless the AREAs are being NFS mounted to a machine where they will be served from a big-endian computer. If this is the case, perform the following procedure to change the setting so the ingestor writes the AREA files in big-endian convention.

1. Edit the file /data/opt/etc/rc.FY2

2. Uncomment the two lines below by removing the # symbol at the beginning of each of the lines. This will cause the ingestor to write the AREA files in big-endian convention.

#BIG_ENDIAN=yes
#export BIG_ENDIAN

3. Stop and restart the ingestor process.
