Connecting Clariion AX4 and ESXi 4
Could help me with a question, I have the following scenario;
I have a storage AX4 iSCSI and 2 servers host ESXi 4.1 which has 2 HBA 1 port iSCSI c/u. configuring storage ports and servers is as follows.
AX4-i
SPA-0: 10.10.5.101 SPA-1: 10.10.5.102
SPB-0: 10.10.6.101 SPB-0: 10.10.6.102
ESXi1 (connected to the SPA-0 and SPB-0)
vSwitch
iSCSI1: 10.10.5.103 iSCSI1: 10.10.6.103
NIC Teaming
NIC2: ACTIVE NIC3: ACTIVE
NIC3: UNUSED NIC2: UNUSED
ESXi2 (connected to the SPA-1 and SPB-1)
vSwitch
iSCSI1: 10.10.5.104 iSCSI1: 10.10.6.104
NIC Teaming
NIC2: ACTIVE NIC3: ACTIVE
NIC3: UNUSED NIC2: UNUSED
Navisphere Express connections option appears for a moment the two ports active, but when recognizes the luns presented to a single esx maintains an active port and other inactive, the luns path refers to an ip address, and now Navisphere Express looks that only activates a port by controller and not the two connected.
ESXi1
A0 - INACTIVE
A1 - INACTIVE
B0 - ACTIVE
B1 - INACTIVE
ESXi2
A0 - INACTIVE
A1 - INACTIVE
B0 - INACTIVE
B1 - Active
If you have any information to help me fix this would be much appreciated.

Hi Buddy,
You need to read this: http://www.vmware.com/pdf/vsphere4/r40/vsp_40_iscsi_san_cfg.pdf
Page 23 explains: Path Selection Plugins
Basically by default ESX only uses one path. Switching it to round robin might help. Make sure you test all your hosts connectivity and check switches for errors when you do this.
This link is old but still informative:

Hope this helps.
