Advanced node failure detection

Cluster Resource Services can now use Hardware Management Console (HMC) or a Virtual I/O Server (VIOS) partition on an Integrated Virtualization Manager (IVM) managed server to detect when a cluster node fails.

Detection of node failures can be accomplished using a HMC or IVM.

To add advanced node failure detection for HMC with a CIM server or IVM, which uses a CIM server, a cluster node that is configured with a cluster monitor must install the following software.

• IBM® i option 33, IBM Portable Application Solutions Environment for i
• 5733-SC1, IBM Portable Utilities for i
• 5733-SC1 option 1, OpenSSH, OpenSSL, zlib
• 5770-UME, IBM Universal Manageability Enablement for i
• HMC version must be V8R8.5.0 or earlier. This is the last version of HMC to support the CIM server.

To add advanced node failure detection for HMC with a representational state transfer (REST) server. A cluster node that is configured with a cluster monitor must have the following software installed.

• IBM i option 33, IBM Portable Application Solutions Environment for i
• IBM i option 3, Extended Base Directory Support
• 5733-SC1, IBM Portable Utilities for i (Only required for initial configuration of a cluster monitor.)
• 5733-SC1 option 1, OpenSSH, OpenSSL, zlib (Only required for initial configuration of a cluster monitor.)
• HMC version must be V8R8.5.0 or later. This is the first version of HMC to support the REST server.
