Use this procedure to replace a failed host adapter in a running cluster. This procedure defines Node A as the node with the failed host adapter that you are replacing.
This procedure relies on the following prerequisites and assumptions.
Except for the failed host adapter, your cluster is operational and all nodes are powered on.
Your nodes are not configured with dynamic reconfiguration functionality.
If your nodes are configured for dynamic reconfiguration and you are using two entirely separate hardware paths to your shared data, see the Sun Cluster Hardware Administration Manual for Solaris OS and skip steps that instruct you to shut down the cluster.
If you are using a single, dual-port HBA to provide the connections to your shared data, you cannot use dynamic reconfiguration for this procedure. Follow all steps in the procedure. For the details on the risks and limitations of this configuration, see Configuring Cluster Nodes With a Single, Dual-Port HBA in Sun Cluster 3.0-3.1 Hardware Administration Manual for Solaris OS.
Determine the resource groups and device groups that are running on Node A.
Record this information because you use this information in Step 11 of this procedure to return resource groups and device groups to Node A.
Record the details of any metadevices that are affected by the failed host adapter.
Record this information because you use it in Step 10 of this procedure to repair any affected metadevices.
Move all resource groups and device groups off Node A.
# scswitch -S -h nodename
Shut down Node A.
For the full procedure about how to shut down and power off a node, see your Sun Cluster system administration documentation.
Power off Node A.
Replace the failed host adapter.
For the procedure about how to remove and add host adapters, see the documentation that shipped with your nodes.
Do you need to upgrade the node's host adapter firmware?
Upgrade the host adapter firmware on Node A.
PatchPro is a patch-management tool that eases the selection and download of patches required for installation or maintenance of Sun Cluster software. PatchPro provides an Interactive Mode tool especially for Sun Cluster. The Interactive Tool makes the installation of patches easier. PatchPro's Expert Mode tool helps you to maintain your configuration with the latest set of patches. Expert Mode is especially useful for obtaining all of the latest patches, not just the high availability and security patches.
To access the PatchPro tool for Sun Cluster software, go to http://www.sun.com/PatchPro/, click Sun Cluster, then choose either Interactive Mode or Expert Mode. Follow the instructions in the PatchPro tool to describe your cluster configuration and download the patches.
For third-party firmware patches, see the SunSolveSM Online site at http://sunsolve.ebay.sun.com.
Boot Node A into cluster mode.
For more information about how to boot nodes, see your Sun Cluster system administration documentation.
Perform any volume management procedures that are necessary to fix any metadevices affected by this procedure, as you identified in Step 2.
For more information, see your volume manager software documentation.
Return the resource groups and device groups you identified in Step 1 to Node A.
# scswitch -z -g resource-group -h nodename # scswitch -z -D device-group-name -h nodename
For more information, see your Sun Cluster system administration documentation.
