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.
