Upgrading firmware on MetroCluster IP switches

Procedure

Check the health of the configuration.

Check that the MetroCluster is configured and in normal mode on each cluster: metrocluster show

cluster_A::> metrocluster show
Cluster                   Entry Name          State
------------------------- ------------------- -----------
 Local: cluster_A         Configuration state configured
                          Mode                normal
                          AUSO Failure Domain auso-on-cluster-disaster
Remote: cluster_B         Configuration state configured
                          Mode                normal
                          AUSO Failure Domain auso-on-cluster-disaster

Check that mirroring is enabled on each node: metrocluster node show

cluster_A::> metrocluster node show
DR                           Configuration  DR
Group Cluster Node           State          Mirroring Mode
----- ------- -------------- -------------- --------- --------------------
1     cluster_A
              node_A_1       configured     enabled   normal
      cluster_B
              node_B_1       configured     enabled   normal
2 entries were displayed.

Check that the MetroCluster components are healthy: metrocluster check run

cluster_A::> metrocluster check run

Last Checked On: 10/1/2014 16:03:37

Component           Result
------------------- ---------
nodes               ok
lifs                ok
config-replication  ok
aggregates          ok
4 entries were displayed.

Command completed. Use the "metrocluster check show -instance" command or sub-commands in "metrocluster check" directory for detailed results.
To check if the nodes are ready to do a switchover or switchback operation, run "metrocluster switchover -simulate" or "metrocluster switchback -simulate", respectively.

Check that there are no health alerts: system health alert show

Install the software on the first switch.
Follow the steps for installing switch software in the relevant section in the MetroCluster IP Installation and Configuration Guide depending on whether the switch type is Cisco or Broadcom:
- Downloading and installing the Cisco switch NX-OS software
- Downloading and installing the Broadcom switch EFOS software
MetroCluster IP installation and configuration

Repeat this step for each of the switches.

Note: In the sections referenced, skip the step on downloading the reference configuration (RCF) files.
Repeat step 1 to check the health of the configuration.
