How to Boot a Cluster

This procedure explains how to start a global cluster or zone cluster whose nodes have been shut down. For global-cluster nodes, the system displays the ok prompt on SPARC systems or the Press any key to continue message on the GRUB based x86 systems.

The phys-schost# prompt reflects a global-cluster prompt. Perform this procedure on a global cluster.

This procedure provides the long forms of the Sun Cluster commands. Most commands also have short forms. Except for the long and short forms of the command names, the commands are identical. For a list of the commands and their short forms, see Appendix B, Sun Cluster Object-Oriented Commands.

To create a zone cluster, follow the instructions in Configuring a Zone Cluster in Sun Cluster Software Installation Guide for Solaris OS.

1. Boot each node into cluster mode. Perform all steps in this procedure from a node of the global cluster.

   • On SPARC based systems, run the following command.

     ok boot

   • On x86 based systems, run the following commands.

     When the GRUB menu is displayed, select the appropriate Solaris entry and press Enter. The GRUB menu appears similar to the following:

     GNU GRUB version 0.95 (631K lower / 2095488K upper memory) +-------------------------------------------------------------------------+ | Solaris 10 /sol_10_x86 | | Solaris failsafe | | | +-------------------------------------------------------------------------+ Use the ^ and v keys to select which entry is highlighted. Press enter to boot the selected OS, 'e' to edit the commands before booting, or 'c' for a command-line.

     For more information about GRUB based booting, see Booting an x86 Based System by Using GRUB (Task Map) in System Administration Guide: Basic Administration.

     Note –

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

   • If you have a zone cluster, you can boot the entire zone cluster.

     phys-schost# clzonecluster boot zoneclustername

   • If you have more than one zone cluster, you can boot all zone clusters. Use + instead of the zoneclustername.

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

   The cluster(1CL) status command reports the global-cluster nodes' status.

   phys-schost# cluster status -t node

   When you run the clzonecluster(1CL) status command from a global-cluster node, the command reports the state of the zone-cluster node.

   phys-schost# clzonecluster status

   Note –

   If a 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.

Example 3–4 SPARC: Booting a Global Cluster

The following example shows the console output when node phys-schost-1 is booted into the global cluster. Similar messages appear on the consoles of the other nodes in the global cluster. When the autoboot property of a zone cluster is set to true, the system automatically boots the zone-cluster node after booting the global-cluster node on that machine.

When a global-cluster node reboots, all zone cluster nodes on that machine halt. Any zone-cluster node on that same machine with the autoboot property set to true boots after the global-cluster node restarts.
