HP XP P9000 for Business Continuity Manager Software Installation Guide

journal cache A memory cache installed in the DKC used by UR. Update data to a data volume may be saved
temporarily in memory as a journal cache during journal creation processing before it serves as
a journal.
journal group A group used for UR. A unit used to preserve consistency in the update sequence when updating
volumes.
L
LDEV logical device
local DKC One of the two disk controllers connected to the primary host in a 2DC configuration with
HyperSwap and UR.
local scan A function to acquire disk configuration information about the volumes on the local disk controller
that are recognized by the operating system (the Gen'ed volume).
log dataset A dataset which the log is written to
log level A level that controls the output of the following types of messages: messages, which are output
to the system log (SYSLOG) while the Business Continuity Manager agent is running, that show
the progress of the communication execution, and error messages that are output when storage
information is collected. This log level is specified by using the initialization parameter LOGLEVEL
of the Business Continuity Manager agent.
log stream The set of data to which the system logger service writes log data
logical DKC A collection of storage system volumes, each of which is assigned a CU number in the range
from 00 to FE. In Business Continuity Manager, logical DKCs are distinguishable from ordinary
DKCs, that is to say, the number assigned to each logical DKC (logical DKC serial number) is
called a DKC serial number.
logical DKC
number
A number (0 or 1) assigned to a logical DKC within the storage system
logical DKC serial
number
A number assigned to each logical DKC
LPAR logical partition
LRECL logical record length
M
M-JNL Master journal. The copy source journal for UR.
main control unit A disk control unit that controls the P-VOL of a TC/TCA/UR copy pair
Mainframe Agent A product used for displaying information about mainframe storage systems in Device Manager
or Replication Manager Software
master journal The copy source journal for UR
MCU Main control unit.
MIH missing interrupt handler
monitor mode A startup mode option for Business Continuity Manager agents. If you start a Business Continuity
Manager agent in the monitor mode, you can only monitor copy groups from Replication Manager
Software.
N
NG scan A function for obtaining disk configuration information about volumes for which the OS is not
recognized (Non Gen'ed volume), of the disk controller volumes directly connected to a host.
No-update journal A journal created by UR after the UR ATTIME suspend time occurs that indicates that an update
did not occur.
Non Gen'ed
volume
A volume not defined by an I/O configuration definition for the operating system (for which the
OS is not recognized), of the disk controller volumes connected directly to a host.
