Powering off an entire MetroCluster IP configuration
You must power off the entire MetroCluster IP configuration and all of the equipment before maintenance or relocation can begin.
|
Beginning with ONTAP 9.8, the storage switch command is replaced with system switch . The following steps show the storage switch command, but if you are running ONTAP 9.8 or later, the system switch command is preferred.
|
-
Verify the MetroCluster configuration from both sites in the MetroCluster configuration.
-
Confirm that the MetroCluster configuration and operational mode are normal.
metrocluster show
-
Run the following command:
metrocluster interconnect show
-
Confirm connectivity to the disks by entering the following command on any one of the MetroCluster nodes:
run local sysconfig -v
-
Run the following command:
storage port show
-
Run the following command:
storage switch show
-
Run the following command:
network interface show
-
Run the following command:
network port show
-
Run the following command:
network device-discovery show
-
Perform a MetroCluster check:
metrocluster check run
-
Display the results of the MetroCluster check:
metrocluster check show
-
Run the following command:
metrocluster configuration-settings interface show
-
-
If necessary, disable AUSO by modifying the AUSO Failure Domain to
auso-disabled
cluster_A_site_A::*>metrocluster modify -auto-switchover-failure-domain auso-disabled
In a MetroCluster IP configuration, the AUSO Failure Domain is already set to 'auso-disabled' unless the configuration is configured with ONTAP Mediator. -
Verify the change using the command
metrocluster operation show
cluster_A_site_A::*> metrocluster operation show Operation: modify State: successful Start Time: 4/25/2020 20:20:36 End Time: 4/25/2020 20:20:36 Errors: -
-
Halt the nodes:
halt
system node halt -node node1_SiteA -inhibit-takeover true -ignore-quorum-warnings true
-
Power off the following equipment at the site:
-
Storage controllers
-
MetroCluster IP switches
-
Storage shelves
-
-
Wait for thirty minutes and then power on all storage shelves, MetroCluster IP switches, and storage controllers.
-
After the controllers are powered on, verify the MetroCluster configuration from both sites.
To verify the configuration, repeat step 1.
-
Perform power cycle checks.
-
Verify that all sync-source SVMs are online:
vserver show
-
Start any sync-source SVMs that are not online:
vserver start
-
