Automatic recognition of floppy drive

I need to know the DCL "COM" file code that will allow a floppy drive to be automatically recognized for OpenVMS 7.3-2.

Re: Automatic recognition of floppy drive

$ search sys$startup:*.com; io,autoconfigure/match=and/window=3

******************************
SYS$COMMON:[SYS$STARTUP]VMS$DEVICE_STARTUP.COM;1

io connect mpa0/noadapter/driver=sys$pipedriver
io autoconfigure ! <=
exit

The line marked "<=" does the recognition.

Re: Automatic recognition of floppy drive

Now that I can recognize a floppy drive with the DCL,

$ io -connect /noadapter/driver=sys$pipedriver
$ io autoconfigure ! <=
$ exit

how do I check for errors if the floppy is not there?

how do I send a message to the screen alerting the operator to "Insert a floppy disk"?

how can $STATUS be used in this scenario?

Re: Automatic recognition of floppy drive

Kenneth,
welcome to VMS forum!

I'm not sure about your real intention; I try to do.
You can know if floppy is recognized usign f$getdvi like follow
$ IF F$GETDVI(floppy_dev,"EXISTS")
$ THEN
$ ... floppy exist
$ ELSE
$ ... execute here Uwe's statement
$ ... so mount new floppy
$ ENDIF

About floppy in drive, I don't know any option of f$getdvi.

Re: Automatic recognition of floppy drive

I have tried F$GETDVI, but have not been able to get it to recognize whether or not a floppy is in the drive or not. Is this the way to approach this?

The autoconfigure only loads the software driver. It does not look for media.

Well, if you just try to mount/for it, that will succeed with media present and will fail, whilest warning the operator is not present:

$ mount/for XXX$DVA0:
%MOUNT-I-OPRQST, Please mount device _XXX$DVA0:
%MOUNT-I-NOOPR, no operator available to service request

I don't think you can detect the floppy presence without attempting a mount.

hth,

Re: Automatic recognition of floppy drive

Kenneth,

Uwes command:

$ mc sysman io autoconfigure


identifies all the devices connected to the alpha and loads the drivers needed for them.

So this command is needed if you dont see yours floppy as a device (probably DVA0). Once you see the device this command is not needed.

There is no special command to check if there is a floppy in the drive. You can just try to mount it with MOUNT/ASSIST.

the line:
io connect mpa0/noadapter/driver=sys$pipedriver

is needed for DCL piping and you dont need it (It was a part of the search command)
