- 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.
