1. Preparing to Upgrade Oracle Solaris Cluster Software
Choosing an Oracle Solaris Cluster Upgrade Method
2. Performing a Standard Upgrade to Oracle Solaris Cluster 3.3 Software
3. Performing a Dual-Partition Upgrade to Oracle Solaris Cluster 3.3 Software
4. Performing a Live Upgrade to Oracle Solaris Cluster 3.3 Software
5. Performing a Rolling Upgrade
7. Recovering From an Incomplete Upgrade
Observe the following requirements and software-support guidelines when you upgrade to Oracle Solaris Cluster 3.3 software:
Upgrade of x86 based systems - On x86 based systems, you cannot upgrade from the Solaris 9 OS to the Oracle Solaris 10 OS. You must reinstall the cluster with a fresh installation of the Oracle Solaris 10 OS and Oracle Solaris Cluster 3.3 software for x86 based systems. Follow procedures in Chapter 2, Installing Software on Global-Cluster Nodes, in Oracle Solaris Cluster Software Installation Guide.
Minimum Oracle Solaris Cluster software version - Oracle Solaris Cluster 3.3 software supports the following direct upgrade paths:
SPARC: From version 3.1 8/05 through version 3.2 11/09 - Use the standard, dual-partition, or live upgrade method.
From version 3.2 including update releases through version 3.2 11/09 - Use the standard, dual-partition, or live upgrade method.
On version 3.3 to an Oracle Solaris Cluster 3.3 update release with no Oracle Solaris upgrade except to an Oracle Solaris update release, or to upgrade only Oracle Solaris to an update release – You can also use the rolling upgrade method.
See Choosing an Oracle Solaris Cluster Upgrade Method for additional requirements and restrictions for each upgrade method.
Minimum Solaris OS - The cluster must run on or be upgraded to at least Solaris 10 10/09 software, including the most current required patches, before you upgrade the Oracle Solaris Cluster software.
Supported hardware - The cluster hardware must be a supported configuration for Oracle Solaris Cluster 3.3 software. Contact your Sun representative for information about current supported Oracle Solaris Cluster configurations.
Architecture changes during upgrade - Oracle Solaris Cluster 3.3 software does not support upgrade between architectures.
Software migration - Do not migrate from one type of software product to another product during Oracle Solaris Cluster upgrade. For example, migration from Solaris Volume Manager disk sets to VxVM disk groups or from UFS file systems to VxFS file systems is not supported during Oracle Solaris Cluster upgrade. Perform only software configuration changes that are specified by upgrade procedures of an installed software product.
Global-devices partition size - If a node uses a dedicated partition for the /global/.devices/node@nodeid file system and the partition is less than 512 Mbytes but it provides sufficient space for existing device nodes, you do not need to change the file-system size. The 512-Mbyte minimum applies to new installations of Oracle Solaris Cluster software.
However, you must still ensure that the global-devices file system has ample space and ample inode capacity for existing devices and for any new devices that you intend to configure. Certain configuration changes, such as adding disks, disk volumes, or metadevices, might require increasing the partition size to provide sufficient additional inodes.
Data services - You must upgrade data-service software to the Oracle Solaris Cluster 3.3 version.
Upgrading to compatible versions - You must upgrade all software on the cluster nodes to a version that is supported by Oracle Solaris Cluster 3.3 software. For example, if a version of an application is supported on Sun Cluster 3.2 software but is not supported on Oracle Solaris Cluster 3.3 software, you must upgrade that application to the version that is supported on Oracle Solaris Cluster 3.3 software, if such a version exists. See Supported Products in Oracle Solaris Cluster 3.3 Release Notes for information about supported products.
Downgrade - Oracle Solaris Cluster 3.3 software does not support any downgrade of Oracle Solaris Cluster software.
Limitation of scinstall for data-service upgrades - The scinstall upgrade utility only upgrades those data services that are provided with Oracle Solaris Cluster 3.3 software. You must manually upgrade any custom or third-party data services.
