How to Boot a Cluster Node

Starting a cluster node can be affected by the quorum configuration. In a two-node cluster, you must have a quorum device configured so that the total quorum count for the cluster is three. You should have one quorum count for each node and one quorum count for the quorum device. In this situation, if the first node is shut down, the second node continues to have quorum and runs as the sole cluster member. For the first node to come back in the cluster as a cluster node, the second node must be up and running. The required cluster quorum count (two) must be present.

1. To start a cluster node that has been shut down, boot the node.

   ok boot

   Messages are displayed on all node consoles as cluster components are activated.

   Note –

   A cluster node must have a working connection to the cluster interconnect to attain cluster membership.

2. Verify that the node has booted without error, and is online.

   The scstat(1M) command reports the status of a node.

   # scstat -n

   Note –

   If a cluster node's /var file system fills up, Sun Cluster might not be able to restart on that node. If this problem arises, see How to Repair a Full /var File System.
