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 - 188.8.131.52 into a vSwitch with 2 vnics of 184.108.40.206 and 220.127.116.11
1 iSCSI Nic - 18.104.22.168 into a vSwitch with 2 vnics of 22.214.171.124 and 126.96.36.199
1 iSCSI Nic - 188.8.131.52 into 1 Physcial switch - 192.160.248.x
1 iSCSI Nic - 184.108.40.206 into 1 Physcial switch - 192.160.249.x
1 Physcial switch - 192.160.248.x into storage array 220.127.116.11
1 Physcial switch - 192.160.249.x into storage array 18.104.22.168
The problem seems to be with Multipathing in ESX. When i setup the iSCSI initiator and use the Dynamic Discovery it finds both the 22.214.171.124 and 126.96.36.199 iSCSI ports. These get added successfully but when i check the path of the iSCSI it has 188.8.131.52 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 184.108.40.206 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 220.127.116.11 and the other 18.104.22.168 for redundency. Is this not possible you cant have two different subnets on the one initiator?
Thanks in advance.
