RE: Preparing for HA solution

["Segars, Steven " <Steven_Segars@xxxxxxx>]

are you looking for a hot box or a hot site? I use to work for a company
that used Visions. We could switch over to the hot "box" in about 20
minutes. My current company is also a "hot site" for disaster recovery for
several companies. Since were the railroad, we cant afford to be down. choo

Subject: 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
