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.

Why not connect directly Storage to th FI? Make your life easier :)

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