LOOKUP uses DBUTIL, which in turn uses files in $STF_INFO_DIR. STF_INFO_DIR is an environment variable specifying where the directory cedr.lbl.gov:/data9/old/parep2/stf/ (or a copy) is locally mounted by NFS. Files in that directory describe data locations in terms of names diskN. For example, the file $STF_INFO_DIR/c90stf1a/ak.loc specifies that the STF1A data for Alaska are in disk130.
When you integrate your public data into the CD-ROM Information System a new unique name diskN (for example disk301) is assigned to each of your local public file systems. (Typically, each diskN corresponds to a CD-ROM.)
To instruct LOOKUP to use your local data, make a local copy of cedr.lbl.gov:/data9/old/parep2/stf/ and modify it as necessary. For example, change ak.loc to point to disk301 instead of disk130. Then change the environment variable STF_INFO_DIR to point to the directory containing your locally modified files.
If your data become temporarily unavailable, temporarily restore STF_INFO_DIR to its original value to obtain data from the standard remote locations.
