12.
Repeat the
cluster ping-cluster
command used in Step 1 with advanced
privilege from a node that has joined the cluster to verify that there is no
failure on any path.
cluster::*> cluster ping-cluster node_name
13. Use the
reload
command to complete the installation of the new image on the
switch.
(CN1610) #reload
The full boot cycle should take approximately 50 seconds. When the switch
reboots, the cluster LIFs will be automatically migrated to run on the
remaining switch and there will be some minor traffic interruption for less
than 10 seconds. To have less interruption, you can migrate the cluster LIFs
off of the switch that is to be upgraded, and then revert the cluster LIFs after
the switch has finished rebooting.
14. After the upgrade is complete and you verify that all of the node interfaces
are up and running, you can repeat the process for the other switch.
Replacing a CN1610 switch
Replacing a defective CN1610 switch in a cluster network is a nondisruptive
procedure (NDU).
Before you begin
The following conditions must exist before performing the switch replacement in
the current environment and on the replacement switch.
v
Existing cluster and network infrastructure:
– Verify that the existing cluster is completely functional and there must be no
defective cluster NICs, and at least one fully functional switch with all of its
cables.
– All cluster ports must be up.
– All cluster logical interfaces (LIFs) must be up and must not have been
migrated.
– The Data ONTAP
cluster ping-cluster -node node1
command must
indicate that
basic connectivity
and
larger than PMTU communication
are
successful on all paths.
v
CN1610 replacement switch:
– Management network connectivity on the replacement switch must be
functional.
