Sun Cluster Goes to the Movies Click, watch, learn! Installing Open HA Cluster 2009.06 Software demonstrates how to install OpenSolaris 2009.06 and Open HA Cluster 2009.06 software on a two-node cluster. Open HA Cluster with HA-xVM Demo shows, according to the demo's author, Neil Garthwaite, that an Open High Availability Cluster (OHAC) resource group managing an xVM guest domain via an OHAC resource can switch an xVM guest domain from one node to another using live migration. What's not shown, Neil adds, is that the OHAC interconnects are used for the live migration. The demo also shows that an OHAC managed xVM guest domain can survive a node crash. In particular, within the demo, resource group RG1 manages xVM domain domu1. RG1 is then switched from node podio2 to node podio1 and domu1 is subsequently live migrated between the two nodes. While RG1/domu1 is online on podio1 that node podio1 is crashed via uadmin 2 1. OHAC automatically detects that failure and restarts domu1 on podio2. This demo is based on Solaris Express Community Edition, Build 86, and Solaris Cluster Express 2/08. To learn more about this project, see OpenSolaris Project: Cluster Agent: OpenSolaris xVM. Solaris Cluster Express Installation on a Single Node shows you how to install Sun's Solaris High Availability (HA) Cluster software on a single node.
