We are about to stripe two 700 MB disk (with separate
disk controller) together.  However, we are not sure that the following
procedures as defined in /usr/man/cat8/invol.8 is correct, and no one
else in local Apollo Support Group can help us with this as they have
never done this before.   We would appreciate any comments.


   % invol

	option: 1 -m
        Select disk: [w=Winch|s=Storage mod|f=Floppy|q=Quit][ctrl#:][unit#]     w0:0
	How many disks will you be grouping together? 2
        Enter the striping option. 1 (sector stripe)
        physical volume name: boot_disk
                Enter remaining members of disk group:
        	Select disk: [w=Winch|s=Storage mod|f=Floppy|q=Quit][ctrl#:][unit#]     w1:0

         .....invol...

          } From /usr/man/cat8/invol.8 as shown in the paragraph below, we deduce
 	  } the following procedures have to be performed to finally stripe the
	  } two disks as one.  
	  }
          > After you've created a multi-disk set with 1 -m, you must run
          > invol's option 2 to add logical volumes to the multi-disk set.
          > Invol will remind you that you must run it with this option.
          > Specify the primary disk of the multi-disk set (the first disk you
          > specified) to invol. If you desire a bootable volume, run invol
          > with option 8, as described above.
	
	option: 2
        Select disk: [w=Winch|s=Storage mod|f=Floppy|q=Quit][ctrl#:][unit#]     w0:0


         .....invol...
                                   
        option: 8
        Select disk: [w=Winch|s=Storage mod|f=Floppy|q=Quit][ctrl#:][unit#]     w0:0  

	.....Striping Complete.....

Many thanks in advance.
