bulk edit data-group (bigip.conf )

Why can you not move it to an external data group? They are functionally the same and the load is atomic.

In any case, if you simply want to add and delete records, you can do it in a regular

tmsh

command, as in

tmsh modify ltm data-group internal my-dg records \
   add { record4 { data def } record5 { data ghi } record6 { data mno } } \
   records delete { record1 record2 record3 }

If you want to replace the entire data group all at once, you can use a

load...merge

:

cat > /var/tmp/new-dg-def.txt << EOF
ltm data-group internal my-dg {
    records {
        record1 {
            data def
        }
        record2 {
            data ghi
        }
        record3 {
            data there
        }
    }
    type string
}
EOF

tmsh load sys config /var/tmp/new-dg-def.txt merge

The last command is the important part. The rest is just to demonstrate what the file contents must be. It is !!! IMPERATIVE !!! that you include the

merge

keyword. If you forget, you will potentially blow away your entire config.

This

load

will validate the syntax before attempting to add, so if there is an error in the source file, it won't replace the data-group.
