Chapter 17 # S scheduling parameter A parameter that represents the priority with which competing services run. The scheduling parameter is defined in the `nhfs.conf` file. See also actual priority, base priority, and relative priority. scoreboard bitmap A file that identifies which data blocks on a replicated partition are modified while the vice-master node is out of service. See also replication and bitmap partition. SCSI (Small Computer System Interface) serviceability The probability that a service can be restored within a specified period of time following a service failure. See also availability, redundancy, and reliability. shared packages Packages that are located on the master node and replicated on the vice-master node. Shared packages can include the Foundation Services packages and user applications. See also nonshared packages. single fault The failure of a master-eligible node, the failure of a service, or the failure of one of the redundant networks. See also double fault. SNDR (Sun StorEdge™ Network Data Replicator) SNMP (Simple Network Management Protocol) soft partition A disk partition on a virtual disk. See also virtual disk. split brain An error scenario in which a cluster has two master nodes. stale cluster An error scenario in which a peer node does not receive information from the master node for more than 10 seconds. standalone CGTP CGTP running on nonpeer nodes. See also CGTP and nonpeer node. startup script A script that launches the Foundation Services daemons, the Solaris operating system daemons, and some companion product daemons. See also Daemon Monitor and nametag. subnet See network part. switchover The planned transfer of a service from the master node to the vice-master node. A switchover can be initiated for the purpose of system recovery or system administration. A switchover is not linked to node failure. See also failover. synchronization The copying of data from the master node to the vice-master node after the vice-master node has been out of service. Synchronization occurs after startup, disk change, failover, or switchover, unless you have delayed the start of synchronization by setting the RNFS_EnableSync parameter to `FALSE` in the `nhfs.conf` file. See also replication. synchronized A state where the replicated partitions on the disks of the master node and vice-master node contain exactly the same data.
