logical DKC A number (0 or 1) assigned to a logical DKC within the disk controller.
number
logical DKC serial A number assigned to each logical DKC.
number
LPAR Logical partition.
LRECL Logical record length.
M
M-JNL Master journal. The copy source journal for Cnt Ac-J.
main control unit A disk control unit that controls the P-VOL of a Cnt Ac-S/Cnt Ac-A/Cnt Ac-J copy pair.
Mainframe Agent A product used for displaying information about mainframe storage systems in Device Manager
or P9000 Replication Manager Software.
master journal The copy source journal for Cnt Ac-J.
MCU Main control unit. A disk control unit that controls the P-VOL of a Cnt Ac-S/Cnt Ac-A/Cnt Ac-J
copy pair.
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 P9000 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 storage system volumes directly connected to a host.
No-update journal A journal created by Cnt Ac-J after the Cnt Ac-J Z 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 storage system volumes connected directly to a host.
Numbers
2DC Two data center.
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 Cnt Ac-J Z 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 Three data center.
3DC Cascade A configuration to perform remote copying with a nearby intermediate site and distant remote
configuration site, in which Cnt Ac-S Z and Cnt Ac-J Zs are applied from the primary site to the intermediate
site, and from the intermediate site to the remote site.
3DC Multi-Target A configuration to perform remote copying with a nearby local site and a distant remote site, in
configuration which Cnt Ac-S Z and Cnt Ac-J Zs are applied from the primary site to the local site, and from
the primary site to the remote site.
4x4 configuration A configuration in which both the primary and secondary sites consist of multiple storage systems
and remote copy is performed to preserve consistency in those multiple storage systems. The
applicable copy type is Cnt Ac-J Z.
4x4x4 Cascade A 3DC Cascade configuration in which Cnt Ac-S Z is applied between the primary site and
configuration intermediate site. Cnt Ac-J Z in a 4x4 configuration is applied between the intermediate site and
remote site. Consistency can be preserved in a 3DC Cascade configuration with multiple DKCs
in one site.
