Veritas silent disk group creation
I am trying to write a kornshell script that will automatically create veritas disk groups. However, the only utility that I can find that will create the diskgroup is vxdiskadd, which prompts with interactive questions. I've tried to pass the answers through to vxdiskadd, but I receive the following errors. Does any know of a different way to create the diskgroups? Another Veritas program that would allow command line parameters? Another way to pass the answers to vxdiskadd?
Code:
**********************************
EXAMPLE OF MANUAL INPUT TO vxdiskadd
**********************************
11:34:42 # vxdiskadd sda

Add or initialize disks
Menu:: VolumeManager/Disk/AddDisks

  Here is the disk selected.  Output format: [Device_Name]

  sda

Continue operation? [y,n,q,?] (default: y) y

  You can choose to add this disk to an existing disk group, a
  new disk group, or leave the disk available for use by future
  add or replacement operations.  To create a new disk group,
  select a disk group name that does not yet exist.  To leave
  the disk available for future use, specify a disk group name
  of "none".

Which disk group [<group>,none,list,q,?] dgGate

Create a new group named dgGate? [y,n,q,?] (default: y) y

Create the disk group as a CDS disk group? [y,n,q,?] (default: y) y

Use a default disk name for the disk? [y,n,q,?] (default: y) y

Add disk as a spare disk for dgGate? [y,n,q,?] (default: n) n

Exclude disk from hot-relocation use? [y,n,q,?] (default: n) n

Add site tag to disk? [y,n,q,?] (default: n) n

  A new disk group will be created named dgGate and the selected disks
  will be added to the disk group with default disk names.

  sda

Continue with operation? [y,n,q,?] (default: y) y

  Initializing device sda.

Enter desired private region length
[<privlen>,q,?] (default: 65536) 65536

  VxVM  NOTICE V-5-2-120
Creating a new disk group named dgGate containing the disk
  device sda with the name dgGate01.

Goodbye.

volmirror

volmirror(8)						      System Manager's Manual						      volmirror(8)

NAME

       volmirror - Mirrors volumes on a disk or control default mirroring

SYNOPSIS

       /usr/sbin/volmirror [-g diskgroup] [-d yes|no] medianame [new_medianame...]

       /usr/sbin/volmirror [-g diskgroup] [-d yes|no] -a  [new_medianame...]

       /usr/sbin/volmirror [-g diskgroup] [-d yes|no]

       /usr/sbin/volmirror [-g diskgroup] -D

OPTIONS

       The  volmirror  command supports the following options: Limits operation of the command to the given disk group, as specified by disk group
       ID or disk group name. The medianame operands will be evaluated relative to the given disk group.  If no disk  group  is  supplied  to  the
       volmirror command, rootdg is presumed.  Changes the default for subsequent volume creation, depending on the option argument. If the option
       argument is yes, all subsequent volumes created using the volassist command will automatically be  created  as  mirrored  volumes.  If  the
       option argument supplied is no, mirroring will be turned off for future volumes by default.  Displays current default status for mirroring.
       Mirrors all existing volumes for the specified disk group.

DESCRIPTION

       The volmirror command provides a mechanism to mirror all the contents of a specified disk, to mirror all currently  unmirrored  volumes	in
       the  specified  disk  group,  or  to change or display the current defaults for mirroring. All volumes that have only a single plex (mirror
       copy), will be mirrored by adding an additional plex.

       Volumes containing subdisks that reside on more than one disk will not be mirrored by volmirror.

       The volmirror command is generally called from the voldiskadm menus. It is not an interactive command and once called, will continue  until
       completion of the operation or until a failure is detected.

									  Note

       Due to the nature of generating mirror copies of volumes, this command may take a considerable time to complete.

       In  the	first  listed  form of the command, the disk media name is supplied on the command line to volmirror. That name is taken to be the
       only disk from which volumes should be mirrored. In the case of mirroring volumes from a specified disk, only simple single-subdisk volumes
       are mirrored.

       In  the	first and second listed forms of the command, the new_medianame ...  parameter identifies a new disk media name (or set of names).
       The mirroring operation being performed will use these names as targets on which to allocate the mirrors. An error will result if the  same
       disk is specified for both the source and target disk and if no other viable targets are supplied.

EXAMPLES

       The following are examples of the use of the volmirror command.	The following command mirrors the contents of the disk named disk01 to any
       available space on any available disk. Subsequent calls to volassist will cause created volumes to be mirrored by  default.   volmirror	-d
       yes  disk01  The  following  command  displays  the current status of default mirroring. It prints the string yes if mirroring is currently
       enabled or no, if not.  volmirror -D The following command mirrors any volumes on disk02 onto disk03.  volmirror disk02 disk03

FILES

       The defaults file for volassist parameters.
