Improved Cluster Installation and Upgrade Functionality

This release introduces several enhancements to the installation and configuration of Sun Cluster software.

• The following menu options are added to the scinstall utility:

  • Typical-mode installation for the first node of a cluster, additional nodes of a cluster, and JumpStart installation setup

  • Single-node cluster installation

  • Cluster upgrade

• The scinstall utility can now automatically select and configure a quorum device as part of configuration processing. This optional feature is available for two-node clusters which use only SCSI shared storage devices that are qualified for use as a quorum device.

• The following file modifications are now automated as part of Sun Cluster configuration processing:

  File Name	Entry Changes
  /etc/hostname.if	An entry for each configured public-network adapter on the node is added, to enable single-adapter IPMP groups.
  /etc/inet/hosts	An entry for each cluster node is added.
  /etc/inet/ntp.conf.cluster	Unused private hostname entries are deleted.
  /etc/nsswitch.conf	Most entries are modified to consult the local files database before performing remote server lookups.
  /etc/system	The entry exclude:lofs is added.

This functionality is reflected in the installation and upgrade procedures in Chapter 2, Installing and Configuring Sun Cluster Software, in Sun Cluster Software Installation Guide for Solaris OS and Chapter 5, Upgrading Sun Cluster Software, in Sun Cluster Software Installation Guide for Solaris OS.
