Sun Cluster System Administration Guide for Solaris OS

How to Boot a Cluster

  1. To start a cluster whose nodes have been shut down and are at the ok prompt or at the Select (b)oot or (i)nterpreter prompt on the Current Boot Parameters screen, boot(1M) each node.

    If you make configuration changes between shutdowns, start the node with the most current configuration first. Except in this situation, the boot order of the nodes does not matter.

    • SPARC: 


      ok boot

    • x86: 


                            <<< Current Boot Parameters >>>
Boot path: /pci@0,0/pci8086,2545@3/pci8086,1460@1d/pci8086,341a@7,1/
sd@0,0:a
Boot args:

Type    b [file-name] [boot-flags] <ENTER>  to boot with options
or      i <ENTER>                           to enter boot interpreter
or      <ENTER>                             to boot with defaults

                  <<< timeout in 5 seconds >>>
Select (b)oot or (i)nterpreter: b

    Messages are displayed 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

    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.

SPARC: Example—Booting a Cluster

The following example shows the console output when booting node phys-schost-1 into the cluster. Similar messages appear on the consoles of the other nodes in the cluster.
