Sun Cluster 3.0-3.1 Hardware Administration Manual for Solaris OS

Dynamic Reconfiguration Operations For Sun Cluster Nodes

The Sun Cluster environment supports Solaris dynamic reconfiguration (DR) operations on qualified servers. Throughout the Sun Cluster Hardware Administration Collection for Solaris OS, there are procedures that require that the user add or remove transport adapters or public network adapters in a cluster node. Contact your service provider for a list of storage arrays that are qualified for use with DR-enabled servers.


Note –

Review the documentation for the Solaris DR feature on your hardware platform before you use the DR feature with Sun Cluster software. All of the requirements, procedures, and restrictions that are documented for the Solaris DR feature also apply to Sun Cluster DR support (except for the operating environment quiescence operation).


Documentation for DR on currently qualified server platforms are listed here.

ProcedureDR Operations in a Cluster With DR-Enabled Servers

Some procedures within the Sun Cluster Hardware Administration Collection for Solaris OS instruct the user to shut down and power off a cluster node before you add, remove, or replace a transport adapter or a public network adapter (PNA).

However, if the node is a server that is enabled with the DR feature, the user does not have to power off the node before you add, remove, or replace the transport adapter or PNA. Instead, do the following:

  1. Follow the procedure steps in Sun Cluster Hardware Administration Collection for Solaris OS, including any steps for disabling and removing the transport adapter or PNA from the active cluster interconnect.

    See the Sun Cluster system administration documentation for instructions about how to remove transport adapters or PNAs from the cluster configuration.

  2. Skip any step that instructs you to power off the node, where the purpose of the power-off is to add, remove, or replace a transport adapter or PNA.

  3. Perform the DR operation (add, remove, or replace) on the transport adapter or PNA.

  4. Continue with the next step of the procedure in Sun Cluster Hardware Administration Collection for Solaris OS.
