Sun Cluster Software Installation Guide for Solaris OS

Using SunPlex Installer to Install Sun Cluster Software


Note –

To add a new node to an existing cluster, instead follow the procedures in How to Configure Sun Cluster Software on Additional Cluster Nodes (scinstall).


This section describes how to install SunPlex Manager software. This section also describes how to use SunPlex Installer, the installation module of SunPlex Manager, to install Sun Cluster software and to establish new cluster nodes. You can also use SunPlex Installer to install or configure one or more of the following additional software products:

Installation Requirements

The following table lists SunPlex Installer installation requirements for these additional software products.

Table 2–4 Requirements to Use SunPlex Installer to Install Software

Software Package 

Installation Requirements 

Solstice DiskSuite or Solaris Volume Manager 

A partition that uses /sds as the mount–point name. The partition must be at least 20 Mbytes in size.

Sun Cluster HA for NFS data service 

  • At least two shared disks, of the same size, that are connected to the same set of nodes.

  • Solstice DiskSuite software installed, or Solaris Volume Manager software configured, by SunPlex Installer.

  • A logical hostname for use by Sun Cluster HA for NFS. The logical hostname must have a valid IP address that is accessible by all cluster nodes. The IP address must be on the same subnet as the base hostnames of the cluster nodes.

  • A test IP address for each node of the cluster. SunPlex Installer uses these test IP addresses to create Internet Protocol (IP) Network Multipathing (IP Network Multipathing) groups for use by Sun Cluster HA for NFS.

Sun Cluster HA for Apache scalable data service 

  • At least two shared disks of the same size that are connected to the same set of nodes.

  • Solstice DiskSuite software installed, or Solaris Volume Manager software configured, by SunPlex Installer.

  • A shared address for use by Sun Cluster HA for Apache. The shared address must have a valid IP address that is accessible by all cluster nodes. The IP address must be on the same subnet as the base hostnames of the cluster nodes.

  • A test IP address for each node of the cluster. SunPlex Installer uses these test IP addresses to create Internet Protocol (IP) Network Multipathing (IP Network Multipathing) groups for use by Sun Cluster HA for Apache.

Test IP Addresses

The test IP addresses that you supply must meet the following requirements:

The following table lists each metaset name and cluster-file-system mount point that is created by SunPlex Installer. The number of metasets and mount points that SunPlex Installer creates depends on the number of shared disks that are connected to the node. For example, if a node is connected to four shared disks, SunPlex Installer creates the mirror-1 and mirror-2 metasets. However, SunPlex Installer does not create the mirror-3 metaset, because the node does not have enough shared disks to create a third metaset.

Table 2–5 Metasets Installed by SunPlex Installer

Shared Disks 

Metaset Name 

Cluster File System Mount Point 

Purpose 

First pair 

mirror-1

/global/mirror-1

Sun Cluster HA for NFS or Sun Cluster HA for Apache scalable data service, or both 

Second pair 

mirror-2

/global/mirror-2

Unused 

Third pair 

mirror-3

/global/mirror-3

Unused 


Note –

If the cluster does not meet the minimum shared-disk requirement, SunPlex Installer still installs the Solstice DiskSuite packages. However, without sufficient shared disks, SunPlex Installer cannot configure the metasets, metadevices, or volumes. SunPlex Installer then cannot configure the cluster file systems that are needed to create instances of the data service.


Character-Set Limitations

SunPlex Installer recognizes a limited character set to increase security. Characters that are not a part of the set are silently filtered out when HTML forms are submitted to the SunPlex Installer server. The following characters are accepted by SunPlex Installer:


()+,-./0-9:=@A-Z^_a-z{|}~

This filter can cause problems in the following two areas:
