2.1.2 How to Boot a Cluster

1. To start a cluster whose nodes have been shut down and are at the ok PROM prompt, boot each node.

   The order in which the nodes are booted does not matter unless if you make configuration changes between shutdowns. In this case, you should start the nodes such that the one with the most current configuration boots first.

   ok boot

   Messages appear on the booted nodes' consoles as cluster components are activated.

   Note -

   Cluster nodes must have a working connection to the cluster interconnect to attain cluster membership.

2. Verify that the nodes booted without error and are online.

   The scstat(1M) command reports the nodes' status.

   # scstat -n
