Hi, 

   What I  "have"   is   virtual LDOM machines  with  two VLAN's   each  using  Multipathing 
 via two I/O  domains. 

   there is   an access Vlan , and a storage_NFS  vlan. 

   only the Access Vlan has  other subnets "on the other side"  of the router 
  the storage VLAN is  Isolated. 
  
  As there are no "routes"   to anywhere  on the storage  vlan,  I need a mechanism  
  to point  the IPMP probing   to  the storage-array  on  the storage net. 
  Therefore my Idea with a faked route to an imaginary subnet in my previous post. 
  
  Its the storage-array that I want to be able to reach. 
  so why not send the icmp probes to it. 
  If the array goes down the  applications wont work anyway. 
  
  As  Mpathd selects an arbitrary  ipaddress  on the storage lan to send 
 probes to  - the probe fails when that arbitrary server  is rebooted  for any reason.
