The thing is the HIHI, HIGH, LOW and LOLO values are initialized in the
record but BOY doesn't seem to be loading them. The record I'm referring
to is as follows:

record(ao,DISK:FORWARDING") {
    field(DESC,"Forwarding Throughput")
    field(DTYP,"Raw Soft Channel")
    field(EGU,"Gbps")
    field(OMSL,"supervisory")
    field(DRVL,0.0)
    field(DRVH,10.0)
    field(LOPR,0.0)
    field(HOPR,10.0)
    field(HIHI,8.0)
    field(HIGH,7.0);
    field(LOW, 1.0);
    field(LOLO,0.0)
}

Not sure about the quotes in this example.
Does the IOC load the database without errors?

Try caget to read the value as a DBR_CTRL_DOUBLE:

   caget -d 34 DISK:FORWARDING

It should also show NaN (actually nan) for fields that the IOC reports as
not initialized.

Hello,

You are right - I get nan for the lo/hi warn/alarm fields using caget.

It doesn't matter if I use the quotes or not. The IOC doesn't display

any errors when loading this db.

Does the fact that the native data type is DBF_DOUBLE have anything to

do with it? I wonder why only those four fields are invalid in this case.
