Upgrading firmware on MetroCluster IP switches
You might need to upgrade the firmware on a MetroCluster IP switch.
You must repeat this task on each of the switches in succession.
Enable console logging before performing this task.
-
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.
You must install the switch software on the switches in the following order: switch_A_1, switch_B_1, switch_A_2, switch_B_2. Follow the steps for installing switch software in the relevant topic depending on whether the switch type is Broadcom, Cisco, or NVIDIA:
-
Repeat the previous step for each of the switches.
-
Repeat Step 1 to check the health of the configuration.
