The SunPlex system uses global devices to provide cluster-wide, highly available access to any device in a cluster, from any node, without regard to where the device is physically attached. In general, if a node fails while providing access to a global device, the Sun Cluster software automatically discovers another path to the device and redirects the access to that path.
The cluster automatically assigns unique IDs to each disk, CD-ROM, and tape device in the cluster. This assignment allows consistent access to each device from any node in the cluster. The global device namespace is held in the /dev/global directory.
Normally, you should see:
