Create port channeling for connectivity to VNX Storage system

How do I create a port-channel on my cisco switch for my new VNX Storage? I am trying to create a new CIFS on my network. When I configure the same port-channel 20 and the same configuration that is on the CS-120 to an unuse interface gig1/29, my existing network CIFS share got disconnected when plug into the VNX storage. Do I create a new Port-channel? What are the steps I need to take?

Currently configuration on my Switch that is connected to EMC CS-120, this port is for CIFS:

interface Port-channel20
switchport
switchport access vlan 101
switchport mode access
!
interface Port-channel21
switchport
switchport access vlan 101
switchport mode access

interface GigabitEthernet1/31
description TO 2FDC4948 G1/31 EMC CS-120 CGE1
switchport access vlan 101
switchport mode access
channel-group 20 mode on
spanning-tree portfast
!
interface GigabitEthernet1/32
description TO 2FDC4948 G1/32 EMC CS-120 CGE0
switchport access vlan 101
switchport mode access
channel-group 20 mode on
spanning-tree portfast
!
interface GigabitEthernet1/33
description TO 2FDC4948 G1/33 EMC CS-120 CGE1
switchport access vlan 101
switchport mode access
channel-group 21 mode on
spanning-tree portfast
!
interface GigabitEthernet1/34
description TO 2FDC4948 G1/34 EMC CS-120 CGE0
switchport access vlan 101
switchport mode access
channel-group 21 mode on
spanning-tree portfast

New Configuration to connect to my EMC VNX (When I plug the VNX cable in, current share drop)

interface GigabitEthernet1/29
description TO 2FDC4948 G1/31 EMC VNX-5300 CGE1
switchport access vlan 101
switchport mode access
channel-group 20 mode on
spanning-tree portfast

Please Advice.

Yes you need separate ether channel for the connection

Do a "show etherchannel" to see which ports are bundled together in one view

Eg from your config, 1/29 and 1/32 belong to Po20

You need to bundle unused ports together to create a new port channell

Interface range gi1/40 - 41
Channel-group 22 mode on

This will bundle port 40 and 41 together to create Po22

Do I have to create a channel-group 22 first?

What is the command for this?

I want to confirm if this is the command I should use to configure my new port.

To Add a Port Channel
switch# configure terminal
switch (config)# interface port-channel 22
switch (config)#switchport
switch (config)#switchport access vlan 101
switch (config)#switchport mode access
switch (config)#exit

To bundle the port:
switch# configure terminal
switch (config)# interface range g1/40-41
switch(config-if)# sswitchport access vlan 101
switch(config-if)# switchport mode access
switch(config-if)#channel-group 22 mode on
switch(config-if)#panning-tree portfast

You guys are the BEST.

Bundling is what adds the port channel. After bundling or adding, you the configure

To bundle/add the port:
switch# configure terminal
switch (config)# interface range g1/40-41
switch(config-if)# switchport access vlan 101
switch(config-if)# switchport mode access
switch(config-if)#channel-group 22 mode on
switch(config-if)#panning-tree portfast
