[rescue] rescue Digest, Vol 77, Issue 4

[Robert Darlington]

We had a project where there were O200 systems that were out in the field
and an O2000 desk side setup the same way at home base.  I remember they
told me that in an emergency where an O200 out in the field had a disk
failure, we could pull the disk from the O2000.  I did not personally ever
test doing this, but from what I remember they were the same physical
disks.  There were some differences between the hardware that were not
obvious though.  The O2000 we had did not have any video display hardware,
but the O200 did (3rd party made video cards that stopped working past
6.5.18 I believe because sgi stopped sharing info with them at that time).
Looking back, I don't have much faith that things would have ever worked,
but they swore it would.  Our O200's outside of my sandbox machines were
never connected with the craylink cables for some reason.  I guess it was
too confusing to have one computer (for all practical purposes) with more
than one property tag.
