To PPRC or Not to PPRC

[Noel Johnston <Noel.Johnston@xxxxxx>]

I'm currently assessing the use of PPRC on a Shark attached to an Iseries.
I'm a bit concerned about how you failover to the secondary Iseries.
It's seems from my reading of the REDBOOK that it could take a couple of
hours to get the system up and running. 
Also it doesn't mention how to fail back to the original system and what
might be involved.
 
I currently have another AS/400 connected to an EMC Symmetrix, so I'm going
to look at TimeFinder/SRDF also.
>From my reading, it seems that the TimeFinder/SRDF solution would be faster
to failover to the secondary Iseries and faster to fail back to the original
system.
 
Has anybody been in a similar situation?
 
P.S. I'm not interested in a software solution (Mimix/DataMirror etc.).
