Need help: how to configure the 5548UP and Nexus 7000 for software iscsi

Hi,

I plan to make connection as below. But do not familiar the switch config. Does anyone can help, much appreciate.

Cisco UCS -> FI -> 5548UP -> Nexus 7000 switch -> storage

Installed VMware ESXi5.1 in UCS. And plan to configure software iscsi.

The vlan on both 5548UP and  Nexus 7000 switch  is 2000.

FI mode is End host.

The ports on 5548up which are connected to FI :

interface Ethernet1/1
  switchport access vlan 2000

interface Ethernet1/2
  switchport access vlan 2000

The ports on 5548up which are connected to Nexus 7000 switch:

interface Ethernet1/18
  switchport access vlan 2000

interface Ethernet1/19
  switchport access vlan 2000

 

The ports on  Nexus 7000 switch which are connected to 5548up:

interface Ethernet8/19
  switchport access vlan 2000
  logging event port link-status
  no shutdown

interface Ethernet8/20
  switchport access vlan 2000
  logging event port link-status
  no shutdown

The ports on  Nexus 7000 switch which are connected to storage:

interface Ethernet8/5
  switchport access vlan 2000
  no logging event port link-status
  no shutdown

interface Ethernet8/6
  switchport access vlan 2000
  no logging event port link-status
  no shutdown

Now the connection is ok, I can add two more vnic for UCS Server. And configure vmkernel networking in esxi5.1

~ # esxcfg-vmknic -l
Interface  Port Group/DVPort   IP Family IP Address                              Netmask         Broadcast       MAC Address       MTU     TSO MSS   Enabled Type
vmk1       iSCSI0              IPv4      11.11.110.100                           255.255.254.0   11.11.111.255   00:50:56:68:97:b6 1500    65535     true    STATIC
vmk2       iSCSI1              IPv4      11.11.110.101                           255.255.254.0   11.11.111.255   00:50:56:64:18:ab 1500    65535     true    STATIC

After add vmk1 to software iscsi port binding, it can see volumes from storage and works well.

Now the problem is I can just add vmk1 to software iscsi port binding, if I want multipath and add vmk2 to port binding. Then the rescan hba in esxi5.1 is very very slow, format disk in VM is also very slow.

I think the connections seem ok, because I can see volumes from esxi5.1, but I am not sure whether it is valid and what casued the rescan so slow with multipath configured.

 

Does anyone can help?

Thanks.

The config is required in testing env. So I can not just change the connection. Thanks.
