hp surestore disk array xp operating system configuration guide: SGI IRIX
The XP array family supports between 1–16 GB of cache memory. In the event of
power loss, the contents of the cache boards are battery backed to survive up to 48
hours.
CDE
Common desktop environment.
CE
Customer engineer.
CFW
Cache fast write.
CH
Channel.
channel adapter
(CHA)
The channel adapter (CHA) provides the interface between the disk array and the
external host system. Occasionally this term is used synonymously with the term
channel host interface processor (CHIP).
channel host interface
processor (CHIP)
Synonymous with the term channel adapter (CHA).
channel processor
(CHP)
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 XP256 supports up to 4 CUs. The XP512/48 supports up to 16 CUs.
Each CU is able to manage up to 256 LDEVs. Therefore, to uniquely identify a
particular LDEV requires both the CU number as well as the LDEV number.
CPU
Central processing unit.
CSA
Canadian Standards Association.
CT
Continuous Track maintenance support application.
CU
Control unit.
CVS
Custom Volume Size (also called Virtual LVI).
daemon
A process that resides in the UNIX system and waits for events and that does not
disappear after an event is carried out.
