If you want to extract large amounts of data from ECFS, we would recommend you to transfer the files in the order in which they are written to tapes. This can be done with the '–order=tape' option of the ecp and emv commands. This option is also available for the els command,

Listing files - example

ecd ec:<ecfs_path_name>

els -l --order=tape ec:2020010100/f*

Note that the path name given to 'els' should be relative. This command shows the files selected with the tape number they are written to together with their position on tape. Files on disk are have no tape information. E.g.:

# ECFS files on disk

2020100100/file1
2020100100/file2

# files on tapes
2020100100/file3 volser:J12551 fileno:144 offset:450852437
2020100100/file4 volser:J12551 fileno:144 offset:505435733
2020100100/file5 volser:J12805 fileno:223 offset:29688824476
2020100100/file6 volser:J12805 fileno:223 offset:42359779994

Getting files

ecd ec:<ecfs_path_name>

Note that you have to use the '-F sourcelist' option.

Error handling

The following techniques are suggested for trapping ECFS error codes when running batch scripts in the Korn shell environment:
