The EISA card used on s700 uses differential SCSI, which would limit
the selection of drives available.  However, all three of the boxes
have a builtin single-ended SCSI implemented.   Standardization of
SCSI is such that it's not possible to make blanket statements about
whether other devices will work.  The s800 machines have disk partitions
hard-coded into the kernel, which I assume would present some problems.

There are no specific lockouts to prevent this, but again it's not
possible to make any guarantees.

I'm not familiar with what you're asking here.  Someone asked about
the 'cs80describe' command, which was an earlier version of the
'diskinfo' command currently shipping with the systems.  This provides
information about both cs80 (HP-IB) and SCSI disk drives, but it's really
just a convenience rather than a necessity for configuring disks.  Someone
else posted a disktab generator, but again, that's a convenience.
