asked on
multipathin on linux host
if we have dual port hba card and if we connect to 2 san switch to use 2 paths for storage.
Where do we need to configure active/active or active/passive? Do we need to do it in storage level? From my understanding, it needs to be done on host level and we need to install multiparth driver on it. Do we need to do anything in storage level or san switch level?

Thank you very much. We are using clarion cx3-20.
1. Zone is configured as this
Server - port1 - connected to san switch 1
server -port2 - connected to san switch 2
san switch1 - connected to sp1
san switch2 - connected to sp2
My question is that, if I configure the connection correctly, Multipath configuration needs to be done on the server level right? Storage or SAN switch doesn't know about the multipathing, it will handle the packets as it receive right?

Ye, you should have powerpath as the managing f access. The free version will deal with failover, a licensed mde can be setup for load balancing.
Or are you using Linux based multipathing?

Yes, native one (linux multipath). I just want to make sure the concept, does storage or san swith know about the multipath? It will just handle the packet as it received right? Like active/active or active/passive? For an example any multipath setting needs to be done in storage or san switch ?
