Glossary
Control unit.
Custom volume size. CVS devices (OPEN-x CVS) are custom volumes
configured using array management software to be smaller than normal
fixed-size OPEN system volumes. Synonymous with volume size
customization (VSC).
Synonymous with the term ACP.
The array hardware that houses the disk array physical disks.
The array hardware that houses the channel adapters and service processor
(SVP).
The unit responsible for data recovery and restoration in the event of a
cache failure.
The physical disk locations associated with a parity group.
The manufacturing label burned into the physical disk controller firmware.
In most cases, the disk type is identical to the disk model number.
The logical devices (LDEVs) associated with each RAID group are
assigned an emulation mode that makes them operate like OPEN system
disk drives. The emulation mode determines the size of an LDEV.
OPEN-3: 2.46 GB
OPEN-8: 7.38 GB
OPEN-9: 7.42 GB
OPEN-E: 13.56 GB
OPEN-K: Not available on XP1024
OPEN-L: 36 GB
OPEN-M Not available on XP1024
OPEN-V: User-defined custom size
Emergency power-off.
Enterprise System Connection (the IBM trademark for optical channels).
A LUN is normally associated with only a single LDEV. The LUSE feature
allows a LUN to be associated with 1 to 36 LDEVs. Essentially, LUSE
makes it possible for applications to access a single large pool of storage.
