Preparing for HA solution

Hi,

after several crashes last year, TPTB finally have agreed to an HA solution for 
our
AS/400. 

We'd like to have a hot-standby and be able to switch over in less than 1 hour.
Currently, it looks like DataMirror will be the HA-provider.

We have an 820 (proc.2396) with about 210GB DASD (fully mirrored) at V5R1.
System is leased until 31Dec. 2003 with full IBM software and hardware 
maintenance.

We have been told we should get a hot-standby with similar setup (CPW-wise).

AFAIK, normal solutions have the stand-by machine sitting mostly idle in  its 
own,
separate machine room with separate network connection and all that stuff.
So, could the stand-by machine be used for any real work (maybe LPAR as a test 
or
development machine)? 

Are there any reports (in-depth) on how this was done. What are the upcoming 
problems?
What should be done in preparation (or can be done)?

Thanks for sharing your experiences,

Oliver
