Glossary
image ID
A globally unique serial number that identifies the point-in-time image source for a volume.
All volumes that have identical image IDs have identical data content, whether they be
snapshots or stand-alone volumes.
initiator
See
host.
I/O Manager
A MIB-specific term for a controller module.
I/O module
See
IOM.
intrinsic methods
Methods inherited from CIM and present in all classes such as getclass, createinstance,
enumerateinstances, and associatorNames in SMI-S.
IOM
Input/output module. An IOM can be either a controller module or an expansion module.
IQN
iSCSI Qualified Name.
iSCSI
Internet SCSI interface protocol.
iSNS
Internet Storage Name Service.
JBOD
“Just a bunch of disks.”
See
drive enclosure.
jumbo frame
In an iSCSI network, a frame that can contain 9000 bytes for large data transfers. A normal
frame can contain 1500 bytes.
large form factor
See
LFF.
LBA
Logical Block Address. The address used for specifying the location of a block of data.
leftover
The state of a disk that the system has excluded from a vdisk because the timestamp in the
disk’s metadata is older than the timestamp of other disks in the vdisk, or because the disk
was not detected during a rescan. A leftover disk cannot be used in another vdisk until the
disk’s metadata is cleared; for information and cautions about doing so, see documentation
topics about clearing disk metadata.
LFF
Large form factor. A type of disk drive.
LIP
Loop Initialization Primitive. An FC primitive used to determine the loop ID for a controller.
logical block address
See
LBA.
Logical Unit Number
See
LUN.
loop
See
FC-AL.
Loop Initialization
Primitive
See
LIP.
LUN
Logical Unit Number. A number that identifies a mapped volume to a host.
MAC address
Media Access Control Address. A unique identifier assigned to network interfaces for
communication on a network.
Management
Controller
See
MC.
Management
Information Base
See
MIB.
map/mapping
Settings that specify whether a volume is presented as a storage device to a host, and how
the host can access the volume. Mapping settings include an access type (read-write,
read-only, or no access), controller host ports through which initiators may access the
volume, and a LUN that identifies the volume to the host.
See also
default mapping, explicit
mapping, and masking.
masking
A volume-mapping setting that specifies no access to that volume by hosts.
See also
default
mapping and explicit mapping.
master volume
A volume that is enabled for snapshots and has an associated snap pool.
MC
Management Controller. A processor (located in a controller module) that is responsible for
human-computer interface and computer-computer interfaces, including the WBI, CLI, and
FTP interfaces, and interacts with the Storage Controller.
See also
EC and SC.
