Hello sunmanagers,

a colleague of mine has a project for networkmanagementstations.
At the moment there is a E3500 as primary server and a Ultra 1 as backup 
both connected to one scsi Raidbox.
The purpose of the installation is that the Ultra 1 will take over all 
services from the E3500 if there is a failure on the box. THis works at the 
moment via a lot of scripts (in specific cases there is a problem that both 
boxes mount the storage at same time very bad thing)
Now the hardware will be changed to a 480R as primary and a 280R as backup 
(both have two LAN-Interface one can be used as private network and also 
modem and RCS) , storage will be a A5200 housing 6 disks (this is really 
not a i/o critical thing). Now we don't can go for clusterservices which 
would be the easiest way to achieve this the question is if anybody out 
there has a comparable scenario running or has ideas how to achieve this. 
At the moment we will go with the volumemanager stuff (deporting and 
importing so you have at least write locks and can check again the failed 
machine). It is not extreme time critical so it can take a little time 
until the backup takes over all services from the failed machine (also MAC 
and IP address)

TIA will summarize

Juergen
