This section describes the supported software and memory requirements for Sun Cluster 3.1 software.
Operating environment and patches – Supported Solaris versions and patches are available at the following URL:
For more details, see Patches and Required Firmware Levels.
Volume managers
On Solaris 8 – Solstice DiskSuiteTM 4.2.1 and VERITAS Volume Manager 3.2 and 3.5.
On Solaris 9 – Solaris Volume Manager and VERITAS Volume Manager 3.5.
If you are upgrading from VERITAS Volume Manager (VxVM) 3.2 to 3.5, the Cluster Volume Manger (CVM) feature will not be available until you install the CVM license key for version 3.5. In VxVM 3.5, the CVM license key for version 3.2 does not enable CVM and must be upgraded to the CVM license key for version 3.5.
File systems –
On Solaris 8 – Solaris UFS and VERITAS File System 3.4 and 3.5.
On Solaris 9 – Solaris UFS and VERITAS File System 3.5.
Data services (agents) – For information on supported data services, see Sun Cluster 3.1 Data Service 5/03 Release Notes.
Sun Cluster 3.0 data services can run on Sun Cluster 3.1, except as noted in Running Sun Cluster HA for Oracle 3.0 on Sun Cluster 3.1.
Memory Requirements – Sun Cluster 3.1 software requires extra memory beyond what is configured for a node under a normal workload. The extra memory equals 128 Mbytes plus ten percent. For example, if a standalone node normally requires 1 Gbyte of memory, you need an extra 256 Mbytes to meet memory requirements.
RSMAPI –Sun Cluster 3.1 software supports the Remote Shared Memory Application Programming Interface (RSMAPI) on RSM-capable interconnects, such as PCI-SCI.
