RE: LPAR ---

["Jeffrey Silberberg" <jsilberberg@xxxxxxxxxxxxxx>]

Glenn,

        Yes, BUT !!  Mimix, DataMirror, DataPropagator, etc... all support
data shadowing ? not disk mirroring as I understand it.  Would you agree ?
If not how would you descibe / define the differences ?

     The original thread was could we "mirror" across LPAR partitions and
since "mirror" is an IOP / hardware function my answer is NO.  As the IOP
and DASD can/must be allocated to a single partition.

      An YES, if you are running a 911 center and want H/A than do not LPAR
a single AS/400 system, instead shadow to multiple systems.  If you are
running a service bureau and need multiple langauge support, or multiple
time zone support, or restricted status of various applications at various
times of the day,  than LPAR is for you.  Lastly,  remember to be real
carefull what you put in the "primary" partition because if you IPL it you
IPL the BOX !!

Lest anyone be confused, MIMIX works on LPAR machines as well. In fact,
everybody's software works on LPAR - that's the way it's designed - to be
transparent to the software - and it is.

A word of caution.....don't think that if you set up a single LPAR system
with a primary and backup partitions that you have  better availability
than if you used two separate systems. You have to keep in mind where the
single points of failure are - in a single system with multiple LPAR
partitions, you have MORE single points of failure, not less.
