SUMMARY - Re: moving DiskSuite mirrored system from 250 to 220

My sincere apology for this very late summary. The project was
canceled and not until now did it come up again.

Many thanks to the following people on suggestions how to best move my
mirrored OS from one system to another where the device names don't
match up.

      From: Truhn Chad M CONT DLVA <TruhnCM@NSWC.NAVY.MIL>
      From: "Dell, Mary" <mdell@mesirowfinancial.com>
      From: rossman@columbia.edu
      From: David Flores <dflores@smi-ps.com>

Mary Dell's suggestion was the simplest and easiest to perform. It
goes like this:
      o break all mirrors (the c0t8d0 pieces)
	      metadetach d0 d2
	      metadetach d10 d12
	      metadetach d30 d32
	      metadetach d40 d42
	      metadetach d50 d52
      o metaclear all mirrors (the c0t8d0 pieces)
	      metaclear d2
	      metaclear d12
	      metaclear d32
	      metaclear d42
	      metaclear d52
      o delete the metastate database on the c0t8d0s7 device
	      metadb -d /dev/dsk/c0t8d0s7
      o halt the system on the Sun 250
      o remove the 2 disks and install them in the new Sun 220
      o boot the Sun 220
      o create  metastate databases on the second disk /dev/dsk/c0t1d0s7
	      metadb -c 3 -a c0t1d0s7
      o initialize and re-attach the d2, d12, d32, d42 and d52 pieces
      o reboot to finalize all

This procedure, as recommended by Mary, worked like a charm !
Many thanks again.

George
