HP XP P9000 Continuous Access Synchronous for Mainframe Systems User Guide

SAN storage-area network
SATA serial Advanced Technology Attachment
SC storage control
SCDS source control dataset
SCI state change interrupt
scripting The use of command line scripts, or spreadsheets downloaded by Configuration File Loader, to
automate storage management operations.
SCSI small computer system interface
secondary site The physical location of the storage system that contains the primary volumes of remote replication
pairs at the main or primary site. The storage system at the secondary site is connected to the
storage system at the main or primary site through remote copy connections. The secondary site
can also be called the “remote site”. See also primary site.
secondary volume The volume in a copy pair that is the copy. The following HP products use the term “secondary
volume”: Remote Web Console, Fast Snap, Snapshot, Business Copy, BC Z, Cnt Ac-S, Continuous
Access Journal, Continuous Access Journal Z, and External Storage Access Manager.
See also primary volume.
seq. sequential
service information
message (SIM)
SIMs are generated by a RAID storage system when it detects an error or service requirement.
SIMs are reported to hosts and displayed on Remote Web Console.
severity level Applies to service information messages (SIMs) and Remote Web Console error codes.
shared volume A volume that is being used by more than one replication function. For example, a volume that
is the primary volume of a Cnt Ac-S pair and the primary volume of a Business Copy pair is a
shared volume.
sidefile An area of cache memory that is used to store updated data for later integration into the copied
data.
SIM service information message
size Generally refers to the storage capacity of a memory module or cache. Not usually used for
storage of data on disk or flash drives.
SM shared memory
SMTP simple mail transfer protocol
snapshot A point-in-time virtual copy of a Snapshot primary volume (P-VOL). The snapshot is maintained
when the P-VOL is updated by storing pre-updated data (snapshot data) in a data pool.
SNMP simple network management protocol
SOM system option mode
source volume
(S-VOL)
The volume in a copy pair containing the original data. The term is used only in the earlier version
of the Remote Web Console GUI (still in use), for the following HP products: BC Z, Dataset
Replication for Mainframe, IBM FlashCopy.
space Generally refers to the data storage capacity of a disk drive or flash drive.
SRM Storage Replication Manager
SSB sense byte
SSID (storage) subsystem identifier. SSIDs are used as an additional way to identify a control unit on
mainframe operating systems. Each group of 64 or 256 volumes requires one SSID, therefore
there can be one or four SSIDs per CU image. For XP P9500, one SSID is associated with 256
volumes.
SSL secure socket layer
steady split In Business Copy, a typical pair split operation in which any remaining differential data from the
P-VOL is copied to the S-VOL and then the pair is split.
