The following commands disable node-facing ports 1 through 12 on switch cs1:
(cs1)# configure
(cs1)(Config)# interface 0/1-0/12
(cs1)(Interface 0/1-0/12)# shutdown
(cs1)(Interface 0/1-0/12)# exit
(cs1)(Config)# exit

The following commands disable node-facing ports 1 to 12 on switch cs2:
(cs2)# configure
(cs2)(Config)# interface 0/1-0/12
(cs2)(Interface 0/1-0/12)# shutdown
(cs2)(Interface 0/1-0/12)# exit
(cs2)(Config)# exit

PUT THE CLUSTER INTO MAINTENANCE MODE (I.E. SUPRESS CASES WITH NETAPP)
system node autosupport invoke -node * -type all -message MAINT=2

MAKE SURE THE CLUSTER LIFS DON'T AUTO REVERT DURING THE PROCESS
network interface modify -vserver Cluster -lif cluster1-01_clus1 -auto-revert false
network interface modify -vserver Cluster -lif cluster1-01_clus2 -auto-revert false
network interface modify -vserver Cluster -lif cluster1-02_clus1 -auto-revert false
y
network interface modify -vserver Cluster -lif cluster1-02_clus2 -auto-revert false
y

MOVE THE 1ST CLUSTER LIF FROM EACH NODE ONTO THE 2ND PORT (I.E. BOTH CLUSTER LIFS ARE NOW ON THE SAME PORT)
network interface migrate -lif cluster1-01_clus1 -source-node cluster1-01 -dest-node cluster1-01 -dest-port e0d -vserver Cluster
network interface migrate -lif cluster1-02_clus1 -source-node cluster1-02 -dest-node cluster1-02 -dest-port e0d -vserver Cluster

MAKE SURE THEY WENT OVER
network interface show -role cluster

DOWN THE PORTS WE JUST MIGRATED OFF OF
network port modify -node cluster1-01 -port e0c -up-admin false
network port modify -node cluster1-02 -port e0c -up-admin false

MAKE SURE THE PORTS ARE DOWN
network port show -role cluster

PERFORM STEP 11-13 (.E. REMOVE THE TWINAXIAL CABLES AND PLUG IN THE FIBER TO THE TOP SWITCH FROM BOTH e0c PORTS)

ENABLE THE NODE FACING PORTS ON THE TOP SWITCH
(cs1)# configure
(cs1)(Config)# interface 0/1-0/12
(cs1)(Interface 0/1-0/12)# no shutdown
(cs1)(Interface 0/1-0/12)# exit
(cs1)(Config)# exit

RE-ENABLE THE PORTS WE SHUT DOWN PREVIOUSLY
network port modify -node cluster1-01 -port e0c -up-admin true
network port modify -node cluster1-02 -port e0c -up-admin true

MAKE SURE THE PORTS ARE UP
network port show -role cluster

REVERT THE LIFS BACK TO THE ORIGINAL PORT
network interface revert -lif cluster1-01_clus1
network interface revert -lif cluster1-02_clus1

MAKE SURE THEY'RE WORKING
network interface show -role cluster

MOVE THE 1ST CLUSTER LIF FROM EACH NODE ONTO THE 2ND PORT (I.E. BOTH CLUSTER LIFS ARE NOW ON THE SAME PORT)
network interface migrate -lif cluster1-01_clus2 -source-node cluster1-01 -dest-node cluster1-01 -dest-port e0c -vserver Cluster
network interface migrate -lif cluster1-02_clus2 -source-node cluster1-02 -dest-node cluster1-02 -dest-port e0c -vserver Cluster

MAKE SURE THEY WENT OVER
network interface show -role cluster

DOWN THE PORTS WE JUST MIGRATED OFF OF
network port modify -node cluster1-01 -port e0d -up-admin false
network port modify -node cluster1-02 -port e0d -up-admin false

MAKE SURE THE PORTS ARE DOWN
network port show -role cluster

PERFORM STEP 23-25 (.E. REMOVE THE TWINAXIAL CABLES AND PLUG IN THE FIBER TO THE TOP SWITCH FROM BOTH e0d PORTS)

ENABLE THE NODE FACING PORTS ON THE BOTTOM SWITCH
(cs2)# configure
(cs2)(Config)# interface 0/1-0/12
(cs2)(Interface 0/1-0/12)# no shutdown
(cs2)(Interface 0/1-0/12)# exit
(cs2)(Config)# exit

RE-ENABLE THE PORTS WE SHUT DOWN PREVIOUSLY
network port modify -node cluster1-01 -port e0d -up-admin true
network port modify -node cluster1-02 -port e0d -up-admin true

MAKE SURE THE PORTS ARE UP
network port show -role cluster

REVERT THE LIFS BACK TO THE ORIGINAL PORT
network interface revert -lif cluster1-01_clus2
network interface revert -lif cluster1-02_clus2

VERIFY THE PORTS ARE SHOWING UP CORRECTLY ON THE SWITCHES
(cs1)# show isdp neighbors
THEN
(cs2)# show isdp neighbors

PERFORM A NETWORK DEVICE DISCOVERY FROM THE CLUSTER
network device-discovery show

DISABLE SWITCHLESS CLUSTER OPTION AND THEN VERIFY IT TOOK
network options switchless-cluster modify -enabled false
network options switchless-cluster show

MAKE SURE THE CLUSTER LIFS ARE SET BACK TO AUTO-REVERT
network interface modify -lif cluster1-01_clus1 -auto-revert true -vserver Cluster
network interface modify -lif cluster1-01_clus2 -auto-revert true -vserver Cluster
network interface modify -lif cluster1-02_clus1 -auto-revert true -vserver Cluster
network interface modify -lif cluster1-02_clus2 -auto-revert true -vserver Cluster

MAKE SURE ALL IS GOOD
cluster show

TAKE THE CLUSTER OUT OF MAINTENANCE MODE (I.E. DON'T SUPRESS CASES WITH NETAPP)
system node autosupport invoke -node * -type all -message MAINT=end
