i imported data group file via gui since i did not see an option to specify local file via tmsh.
the data group file is in system, file management, data group file list menu.
) list sys file data-group
sys file data-group test {
checksum SHA1:59:140c98ed7d3dbfbdb49e74d2967ba029dc86d363

}
then i created external data group via tmsh.
) create ltm data-group external test_datgroup external-file-name test
) list ltm data-group
ltm data-group external test_datgroup {
external-file-name test
type string
}
