[Simh] Size of disks created by Simulator

[Mark Pizzolato - Info Comm]

The disks you've got and the size that they are, are a direct reflection of what you've got in your configuration file (combined with default values for disk types).

Hi Priya,

The MSCP disk controller provides emulation for 4 separate disks, and up to 4 separate MSCP controllers can be enabled and configured.

Each disk associated with a particular MSCP controller can emulate a traditional disk model (RD54, RA81, etc.) with its natural size or can be an arbitrary sized device using the RAUSER disk type.  The following commands entered directly into the simulator or in its configuration file can adjust these details:

     sim> SET RQ0 RA90
     sim> SET RQ1 RAUSER=4096

The HELP command will explain many potential details:

    sim> HELP RQ

FYI, the simulator automatically looks for and loads a configuration file called simulator-name.ini when it starts.  An arbitrarily named configuration file can be specified on the command line when invoking the simulator:

     $ vax config.ini

The commands within a configuration file will be displayed as they are executed if the -V switch is entered on the command line:

    $ vax -V
or
     sim> do -V otherconfig.ini

If your configuration file starts a simulator executing instructions (BOOT, GO,RUN, etc.), then you won't ever see the "sim> " prompt.

While a simulator is executing, entering the ^E character will drop you back to the "sim> " prompt.  Once there, you can look around, and/or change details of the simulator configuration.

Subject: [Simh] Size of disks created by Simulator

Hi,

I have a question about the disks created during simulation.
I noticed that 3 disks get attached when we run the simulator for the first time.

[root at localhost data]# ls
cd.iso  d0.dsk  d1.dsk  d2.dsk  ka655x.bin  nvram.bin

ford/system$ sho dev d

Device                  Device           Error    Volume         Free

 Name                   Status           Count     Label        Blocks
DNFS0:                  Online                 0
FORD$DUA0:          Mounted             0      FORD           2371878
FORD$DUA1:          Mounted alloc     0      DATA1          2940579
FORD$DUA2:          Mounted alloc     0      DATA2          2940579
FORD$DUA3:           Online                0


Is there a way to increase the size of any these disks ?
