inconsistent-stopped
In a Global Mirror relationship, the state that occurs when the primary
virtual disk (VDisk) is accessible for read and write input/output (I/O)
operations, but the secondary VDisk is not accessible for either read or
write I/O operations.
indication
An object representation of an event.
initial microcode load (IML)
In SAN Volume Controller, the process by which the run-time code and
data for a node are loaded into memory and initialized.
initiator
The system component that originates an I/O command over an I/O bus
or network. I/O adapters, network interface cards, and intelligent
controller device I/O bus control ASICs are typical initiators. (S) See also
logical unit number.
input/output (I/O)
Pertaining to a functional unit or communication path involved in an input
process, an output process, or both, concurrently or not, and to the data
involved in such a process.
instance
An individual object that is a member of some class. In object-oriented
programming, an object is created by instantiating a class.
integrity
The ability of a system to either return only correct data or respond that it
cannot return correct data.
Internet Protocol (IP)
In the Internet suite of protocols, a connectionless protocol that routes data
through a network or interconnected networks and acts as an intermediary
between the higher protocol layers and the physical network.
interswitch link (ISL)
The physical connection that carries a protocol for interconnecting multiple
routers and switches in a storage area network.
I/O See input/output.
I/O group
A collection of virtual disks (VDisks) and node relationships that present a
common interface to host systems.
I/O throttling rate
The maximum rate at which an I/O transaction is accepted for this virtual
disk (VDisk).
IP See Internet Protocol.
IP address
The unique 32-bit address that specifies the location of each device or
workstation in the Internet. For example, 9.67.97.103 is an IP address.
ISL See interswitch link.
ISL hop
Considering all pairs of node ports (N-ports) in a fabric and measuring
distance only in terms of interswitch links (ISLs) in the fabric, the number
