– Console access to the replacement switch must be in place.
– All relevant switch ports for node connection must be disabled on ports 1
through 12.
– All Inter-Switch Link (ISL) ports must be enabled on ports 13 through 16.
– The desired Reference configuration file (RCF) and FASTPATH operating
system image switch must be loaded onto the switch.
– Initial customization of the switch must be complete.
About this task
This procedure replaces an existing CN1610 cluster switch (CL1 in this procedure)
with a new CN1610 switch (newCL1).
The examples in this procedure use the following switch and node nomenclature:
v
The names of the existing CN1610 switches are CL1 and CL2
v
The name of the new CN1610 switch is newCL1
v
The node names are node1 and node2
v
The names of the Vservers are node1 and node2
v
The cluster ports on each node are named e1a and e2a
v
The names of the cluster LIFs connected to CL1 and CL2 are clus1 and clus2
v
The prompt for changes to all cluster nodes is
cluster::*>
Procedure
1.
Install the appropriate RCF and image on the newCL1 switch and make any
necessary site preparations. This optional step is to verify, download, and
install the appropriate versions of the RCF and FASTPATH software for the
new switch. If you have verified that the new switch is correctly set up and
does not need updates to the RCF and FASTPATH software, continue to step
2.
a.
Go to the
IBM N series Cluster and Management Network Switches Reference
Configuration File Description Page
on the IBM N series support website.
b.
Click the link for the
Cluster Network and Management Network Compatibility
Matrix
and note the required switch software version.
c.
Click your browser's back arrow to return to the
Description
page, click
CONTINUE
, accept the license agreement, and go to the
Download
page.
d.
Follow the steps on the
Download
page to download the correct RCF and
FASTPATH files for the version of Data ONTAP software you are
installing.
2.
On the new switch, shut down all of the ports that will be connected to the
node cluster interfaces (ports 1 to 12). If the switch that you are replacing is
not functional and powered down, go to step 4. The LIFs on the cluster nodes
should have already failed over to the other cluster port for each node.
(newCL1) #config
(newCL1)(config)#interface 0/1-1/12
(newCL1)(interface 0/1-1/12)#shutdown
3.
On all of the cluster nodes, migrate all of the cluster LIFs currently connected
to CL1 to CL2 by using the
network interface migrate
command.
This example migrates the LIF clus1 on a Vserver named node1 to port e2a on
node1. The second command migrates the LIF clus1 on a Vserver named
node2 to port e2a on node1.
