vSphere 4 iSCSI
Posted on 2011-09-02
I need some help setting up my vSphere iSCSI connections.
Setup is as follows:
1 ESX server with 2 iSCSI Nics,
2 Physical switches
1 Storage Array with 1 controller and 2 iSCSI Nics
1 iSCSI Nic - 184.108.40.206 into a vSwitch with 2 vnics of 220.127.116.11 and 18.104.22.168
1 iSCSI Nic - 22.214.171.124 into a vSwitch with 2 vnics of 126.96.36.199 and 188.8.131.52
1 iSCSI Nic - 184.108.40.206 into 1 Physcial switch - 192.160.248.x
1 iSCSI Nic - 220.127.116.11 into 1 Physcial switch - 192.160.249.x
1 Physcial switch - 192.160.248.x into storage array 18.104.22.168
1 Physcial switch - 192.160.249.x into storage array 22.214.171.124
The problem seems to be with Multipathing in ESX. When i setup the iSCSI initiator and use the Dynamic Discovery it finds both the 126.96.36.199 and 188.8.131.52 iSCSI ports. These get added successfully but when i check the path of the iSCSI it has 184.108.40.206 twice. One connection states Active I/O and the other active.
If i pull out the network cable the connection is lost because there is no 220.127.116.11 as one of the paths. I really need some help on this experts, ive been racking my brain, im so close to finishing the configuration.
I want one of the paths to be 18.104.22.168 and the other 22.214.171.124 for redundency. Is this not possible you cant have two different subnets on the one initiator?
Thanks in advance.
