Hi,
i have to implement a multipath strategy on an infrastructure with one ETERNUS DX80 iSCSI with 2 module.
At the moment the configuration in production is:
One 1 gigabit SWITCH
One VSphere 5 Cluster (2 server connected to the switch above)
One ETERNUS DX80 iSCSI with 2 module (used with cluster) with 1 LUN - 1 VOLUME and all the traffic on the CM#0 PORT#0
I have a third server with ESXi 5 to make tests about multipath/failover for iSCSI and other traffic, and my idea is to configure server, switch and SAN in this mode:
NIC0 connected to SWITCH0 connected to CM#0 - PORT#1
NIC1 connected to SWITCH1 connected to CM#1 - PORT#1
I read that it is necessary to set Reset Group, but i don't know what it could happen if i do this in production environment.So my questions are:
1. What do i need to setup Reset Group ?
2. If i simulate network failure with my third server to see if multipath work, is there the risk to lose connection between the production cluster and SAN ?
Than you very much.
