Problem Description: 
   The user incurs problems when trying to run 'format -d' on a system
   with multiple IPI controllers. This option 'format -d' will only work on
   drives that are connected to the first controller. If the user attempts
   to use 'format -d' on a drive that is connected to any other IPI controller
   that isn't the first one, the following error will be displayed:
	'Unable to find specified disk'
   although the disk is available.

   Actually, format is converting the user-specified unit number to binary,
   whereas the unit number is stored as a two-digit hex number in the disk
   configuration information for the disk.  This is dangerous as it is
   possible to end up modifying the wrong disk.



INSTALL:

NOTE: IPI Dual Port installation requires a unique executable.
      Install the version suffixed by '_IDP'.

1) Login as root.

2) save existing copy of rformat:
   mv /usr/kvm/format /usr/kvm/format.fcs

3) install new format:
   cp sun4/{4.1.2;4.1.2_IDP}/format /usr/kvm/format
   chown root.staff /usr/kvm/format
