Sun Cluster 3.2 software requires at least the End User Solaris Software Group. However, other components of your cluster configuration might have their own Solaris software requirements as well. Consider the following information when you decide which Solaris software group you are installing.
Servers - Check your server documentation for any Solaris software requirements. For example , Sun EnterpriseTM 10000 servers require the Entire Solaris Software Group Plus OEM Support.
SCI-PCI adapters - To use SCI-PCI adapters, which are available for use in SPARC based clusters only, or the Remote Shared Memory Application Programming Interface (RSMAPI), ensure that you install the RSMAPI software packages, which are SUNWrsm and SUNWrsmo, and for the Solaris 9 OS on SPARC based platforms also SUNWrsmx and SUNWrsmox. The RSMAPI software packages are included only in some Solaris software groups. For example, the Developer Solaris Software Group includes the RSMAPI software packages but the End User Solaris Software Group does not.
If the software group that you install does not include the RSMAPI software packages, install the RSMAPI software packages manually before you install Sun Cluster software. Use the pkgadd(1M) command to manually install the software packages. See the Section (3RSM) man pages for information about using the RSMAPI.
Additional Solaris packages - You might need to install other Solaris software packages that are not part of the End User Solaris Software Group. The Apache HTTP server packages are one example. Third-party software, such as ORACLE®, might also require additional Solaris software packages. See your third-party documentation for any Solaris software requirements.
To avoid the need to manually install Solaris software packages, install the Entire Solaris Software Group Plus OEM Support.
