Adding MetroCluster configurations

After installing the Lenovo MetroCluster Tiebreaker software, you can add more MetroCluster configurations, one at a time.

1. Use the Tiebreaker command-line interface (CLI) monitor add command to add MetroCluster configurations.

   If you are using the host name, it must be the fully qualified domain name (FQDN).

   Example

   The following example shows the configuration of cluster_A:

   MetroCluster Tiebreaker :> monitor add wizard
   Enter monitor Name: cluster_A
   Enter Cluster IP Address: 10.222.196.130
   Enter Cluster Username: admin
   Enter Cluster Password:
   Enter Peer Cluster IP Address: 10.222.196.40
   Enter Peer Cluster Username: admin
   Enter Peer Cluster Password:
   Successfully added monitor to MetroCluster Tiebreaker software.
   
   
2. Confirm that the MetroCluster configuration was added properly by using the Tiebreaker CLI monitor show -status command.

   Example

   MetroCluster Tiebreaker :> monitor show -status
   
3. Optional: Disable the observer mode for the Tiebreaker software to automatically initiate a switchover after it detects a site failure: monitor modify -monitor-name monitor_name -observer-mode false

   Example

   MetroCluster Tiebreaker :> monitor modify -monitor-name 8pack -observer-mode false
   Warning: If you are turning observer-mode to false, make sure to review the 'risks and limitations'
   as described in the MetroCluster Tiebreaker Installation and Configuration Guide.
   Are you sure you want to enable automatic switchover capability for monitor "8pack"? [Y/N]: y
