UnixWare 7 NonStop Clusters Release 7.1.1+IP New Features

  1. Open Cluster Interconnect with IP

    The Open Cluster Interconnect with IP feature supports the establishment of a two-node cluster using any interconnect (with restrictions, listed below) supporting the IP protocol. The choice between ServerNet and IP interconnection is made during installation. IP-based cluster operations are supported only in a two-node, co-located configuration.

    IP protocol interconnect restrictions are:

  2. Fibre Channel Direct Disk Access by Pairs of Nodes

    The Fibre Channel Direct Disk Access by Pairs of Nodes feature allows direct access to FCAL disk enclosures from each node of a cluster. This allows the user to configure either node of a failover pair to directly access disks within a disk enclosure rather than forcing all disks to be directly accessible from only one node of the failover node pair. For FCAL disk subsystems, users can designate a preferred node for each disk enclosure. All filesystems within the disk enclosure are mounted on the preferred node whenever the preferred node is up. The filesystems failover to the specified backup node when the preferred node goes down due either to failure or to orderly shutdown. All filesystems within a disk enclosure are automatically remounted on the preferred node when the preferred node rejoins the cluster.

  3. GUI Configuration for File System Manager

    The GUI Configuration for File System Manager adds the following features to the SCOadmin File System Manager:

  4. System Availability Monitor and GUI

    The System Availability Monitor (SAM) records and reports on the failures of a cluster and its individual nodes. Up and down events are recorded in a log file, which is subsequently analyzed by a report generator. Both graphical and command line interfaces are provided for user access to the report generator. The installed online documentation set provides a manual page, intro_sam(1M), that gives an overview of the operation and use of SAM.

  5. GUI for Keepalive Configuration Manager

    The Keepalive Configuration Manager (KCM) provides an interface for creating sets of configuration files for the processes you want the keepalive subsystem to monitor. Dialogs provide fields for specifying the process node, favored and backup nodes, node selection policy for restarting the process, number of instances of the process to register, a process restart script, and the registration command.

  6. NonStop Clusters Licensing

    NonStop Clusters licensing is now enforced. The kernels on all nodes now know how many licenses have been entered. Installation of more nodes than the current number of licenses will succeed, but having a node boot into the cluster without a license will result in error messages and the halting of the offending node. No enforcement will be in effect for the single root node, so that a single node cluster does not need a license.

  7. IP Aliasing on CVIP

    IP aliasing is a feature that allows network interfaces to support more than one IP address. The IP Aliasing on CVIP feature provides support for adding aliases to the CVIP interface, thereby getting failover of those interfaces.
