The processors located on the channel adapter (CHA).
CHPID Channel path identifier.
CKD Count key data.
CL Cluster.
command device A volume on the disk array that accepts CA or BC control operations which
are then executed by the disk array.
configuration file A file that defines the pair configurations.
consistency group ID
(CTGID)
The group identifier for which the disk array guarantees the sequence of
asynchronous data transfer for the asynchronous CA volume group.
control unit To organize the storage space attached to the DKC, you can group similarly
configured logical devices (LDEVs) with unique control unit images
(CUs). CUs are numbered sequentially. The disk array supports a certain
number of CUs, depending on the disk array model. Each CU can manage
multiple LDEVs. Therefore, to uniquely identify a particular LDEV
requires both the CU number and the LDEV number.

daemon A process that runs in the background and performs a specific operation at
