L
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 A number (0 or 1) assigned to a logical DKC within the storage system
number
logical DKC serial A number assigned to each logical DKC
number
M
M-JNL 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 XP Replication Manager Software
master journal The copy source journal for UR
MCU Main control unit.
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 XP 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 A volume not defined by an I/O configuration definition for the operating system (for which the
volume OS is not recognized), of the disk controller volumes connected directly to a host.
Numbers
2DC configuration A configuration in which remote copying is performed from the primary site to the secondary site
2DC configuration A configuration that performs a delta resync between the primary site and a secondary site, after
with HyperSwap a HyperSwap on the primary site. This enables a 2DC configuration to be maintained in which
and UR applications can be continued even after a HyperSwap, and for the volumes that are the
destinations for I/Os to be switched around without the user being aware that anything happened.
3DC Cascade A configuration to perform remote copying with a nearby intermediate site and distant remote
configuration site, in which TCs and URs are applied from the primary site to the intermediate site, and from
the intermediate site to the remote site
