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