To answer my question, its as easy as:
1.removing the failed drive, and replacing the second
one, as long as the system was not shutdown after the
failed drive.
2. sys_check is a script! (didn't check that), one can
read. Otherwise, the command /usr/lbin/ra200info gives
all the info I wanted.

Responses in full, might be helpful to someone else:

sys_check is a script you can read.
ra200info xcr0 -f
where xcr0 is the first controller.

There is an on-line SWXCR management utility; it also
comes on a floppy
and
references "unix" on the label. Install that, and
you'll have an
x-windows
utility that can display your drive status and handle
replecement of a
failed drive.
The latest version of the utility I have isn't V5
aware, so it looks
for
V4-style device names. To get it to to work, I had to
figure out the
device
numbers for (for example) my /dev/rdisk/dsk0c device,
then create a
/dev/rre0c device with those same numbers so the
utility could find the
controller.

The swxcrmgr is the utility on the floppy. Yes, the
system would need
to be
down to use swxcrmgr.
Usually with this controller, there should be a Unix
"monitoring"
interface
(probably on another floppy), but it wouldn't be a
utility where you
can
actually manipulate the controller ("read-only").
As long as the drive shows "FAILED" you _should_ be
okay just to swap
it out
and replace it. The controller should automatically
rebuild with no
intervention. (sys_check should indicate that the
drive is rebuilding,
then
show it become optimal again)

The only way I know of to replace the drive while the
system is online
is the command swxcrmgr.
Try accessing the swxcrmgr command from the console
terminal while you
are logged with username root
If it is not there, then you have to take the system
down and run ecu
then run the program swxcrmgr from a floppy
It is very easy to replace the failed drive using any
of the ways
above, just "FAIL" the drive, remove it, then put a
new one, then make
it OPTIMAL.
Hope that helps.

swxcrmgr is a stand alone utility to setup and
configure the swxcr raid
controllers.
since the machine is still running even with the dead
drive in it one
can
assume that this is either RAID5 running in degraded
mode, RAID5 having
a
hot spare (which is now in use) or RAID3 (a shadow set
now not
shadowing). I
very much assume this to be RAID5!!
To replace the drive simply pull the dead one out -
wait approx. 5
minutes
(to let the controller settle all his checks) then
insert a new (or
working) drive.
NOTE:
The replacement drive NEEDS to be at least the same
capacity as the
dead one
or larger (an equal type is probably best).
After replacement the recovery happens automatically -
very visible
when
looking at the drive bay.
IMPORTANT:
Do NOT under nay circumstance power off/on the system.
If you do, the
fault
condition will be written into the swxcr's
configuration and you will
need
the standalone swxcrmgr utility to correct the
situation.
good luck
