Upgrading to Sun Cluster 3.1 10/03 Software (Rolling)
This section provides the following procedure to perform a rolling upgrade from Sun Cluster 3.1 software to Sun Cluster 3.1 10/03 software. In a rolling upgrade, you upgrade one cluster node at a time, while the other cluster nodes remain in production.
To upgrade from Sun Cluster 3.0 software, perform the procedures in Upgrading to Sun Cluster 3.1 10/03 Software (Nonrolling).
Note - Sun Cluster 3.1 10/03 software does not support rolling upgrade from Solaris 8 software to Solaris 9 software. You can upgrade Solaris software to an update release during Sun Cluster rolling upgrade. To upgrade a Sun Cluster configuration from Solaris 8 software to Solaris 9 software, perform the procedures in Upgrading to Sun Cluster 3.1 10/03 Software (Nonrolling).
Table 3-2 Task Map: Upgrading to Sun Cluster 3.1 10/03 Software (Nonrolling)
Task | Instructions |
|---|---|
1. Read the upgrade requirements and restrictions. | |
2. Take the cluster out of production, disable resources, and ensure that shared data and system disks are backed up. | |
3. Upgrade the Solaris software, if necessary, to a supported Solaris update release. Optionally, upgrade VERITAS Volume Manager (VxVM). | How to Upgrade to a Solaris Maintenance Update Release (Rolling) |
4. Upgrade to Sun Cluster 3.1 10/03 framework and data-service software. If necessary, upgrade applications. If you upgraded VxVM, upgrade disk groups. | |
5. Upgrade the Sun Cluster module to Sun Management Center, if needed. Reregister resource types, enable resources, and bring resource groups online. | How to Finish Upgrading to Sun Cluster 3.1 10/03 Software (Rolling) |
How to Prepare the Cluster for Upgrade (Rolling)
Perform this procedure on one node at a time. The upgraded node is taken out of the cluster, while the remaining nodes continue to function as active cluster members.
Note - Do not use any new features of the update release, install new data services, or issue any administrative configuration commands until all nodes of the cluster are successfully upgraded.
Ensure that the configuration meets requirements for upgrade.
Have available the CD-ROMs, documentation, and patches for all the software products you are upgrading before you begin to upgrade the cluster.
Solaris 8 or Solaris 9 operating environment
Sun Cluster 3.1 10/03 framework
Sun Cluster 3.1 10/03 data services (agents)
Applications that are managed by Sun Cluster 3.1 10/03 data-service agents
See "Patches and Required Firmware Levels" in Sun Cluster 3.1 Release Notes for the location of patches and installation instructions.
(Optional) Install Sun Cluster 3.1 10/03 documentation.
Install the documentation packages on your preferred location, such as an administrative console or a documentation server. See the index.html file at the top level of the Sun Cluster 3.1 10/03 CD-ROM to access installation instructions.
From any node, view the current status of the cluster.
Save the output as a baseline for later comparison.
% scstat % scrgadm -pv[v]
See the scstat(1M) and scrgadm(1M) man pages for more information.
Become superuser on one node of the cluster to upgrade.
Move all resource groups and device groups that are running on the node to upgrade.
# scswitch -S -h from-node
-S Moves all resource groups and device groups
-h from-node Specifies the name of the node from which to move resource groups and device groups
See the scswitch(1M) man page for more information.
Verify that the evacuation completed successfully.
# scstat -g -D
-g Show status for all resource groups
-D Show status for all disk device groups
Ensure that the system disk and data is backed up.
Shut down the node to upgrade and boot it into noncluster mode.
# shutdown -y -g0 ok boot -x
The other nodes of the cluster continue to function as active cluster members.
Do you intend to upgrade the Solaris software to a Maintenance Update release?
Note - The cluster must already run on, or be upgraded to, at least the minimum required level of the Solaris operating environment to support Sun Cluster 3.1 10/03 software. See the Sun Cluster 3.1 10/03 Release Notes for information about supported releases of the Solaris operating environment.
How to Upgrade to a Solaris Maintenance Update Release (Rolling)
Perform this procedure to upgrade the Solaris 8 or Solaris 9 operating environment to a supported Maintenance Update release.
Note - To upgrade a cluster from Solaris 8 to Solaris 9 software, with or without upgrading Sun Cluster software as well, you must perform a nonrolling upgrade. Go to Upgrading to Sun Cluster 3.1 10/03 Software (Nonrolling).
Ensure that all steps in How to Prepare the Cluster for Upgrade (Rolling) are completed.
Temporarily comment out all entries for globally mounted file systems in the /etc/vfstab file.
Perform this step to prevent the Solaris upgrade from attempting to mount the global devices.
Follow instructions in your installation procedures for the Solaris Maintenance Update version you are upgrading to.
Note - Do not reboot the node when prompted to reboot.
Uncomment all entries in the /a/etc/vfstab file for globally mounted file systems that you commented out in Step 2.
Install any required Solaris software patches and hardware-related patches, and download any needed firmware that is contained in the hardware patches.
Note - Do not reboot the node until Step 6.
Reboot the node into noncluster mode.
Include the double dashes (--) in the following command:
# reboot -- -x
Upgrade the Sun Cluster software.
