warranty period for the licensed functions
and they include the following machine
types: 2396 (one-year warranty), 2397
(two-year warranty), 2398 (3-year
warranty), and 2399 (four-year warranty).
Each 239x function authorization machine
type corresponds to the 242x hardware
machine type that represents the same
warranty period. For example, you order
a 2398 (3-year warranty) function
authorization machine type for a 2423
(3-year warranty) hardware machine. The
239x machine types are used only for
purposes of billing and authorizing the
licensed functions on the 242x machines.
The 239x machine types have one model
(Model LFA) with several types of
available licenses for that model. For
example, Model LFA, RMC license is for
the remote mirror and copy function on a
242x storage unit.
242x Hardware machine types for the IBM
System Storage DS8000 series. The 242x
hardware machine types include machine
types 2421 (one-year warranty), 2422
(two-year warranty), 2423 (3-year
warranty), and 2424 (four-year warranty).
Hardware models for the 242x machine
types include base units 931, 932, 9B2 and
expansion units 92E and 9AE.
3390 The machine number of an IBM disk
storage system. The Enterprise Storage
Server, when interfaced to IBM System z
hosts, is set up to appear as one or more
3390 devices, with a choice of 3390-2,
3390-3, or 3390-9 track formats.
3990
The machine number of an IBM control
unit.
7133 The machine number of an IBM disk
storage system. The Model D40 and 020
drawers of the 7133 can be installed in the
2105-100 expansion enclosure of the ESS.
A
access 1) To obtain computing services or data.
2) In computer security, a specific type of
interaction between a subject and an
object that results in flow of information
from one to the other.
access-any mode
One of the two access modes that can be
set for the storage unit during initial
configuration. It enables all
fibre-channel-attached host systems with
no defined access profile to access all
logical volumes on the storage unit. With
a profile defined in DS Storage Manager
for a particular host, that host has access
only to volumes that are assigned to the
WWPN for that host. See also pseudo host
and worldwide port name.
ACK See request for acknowledgment and
acknowledgment.
agent
A program that automatically performs
some service without user intervention or
on a regular schedule. See also subagent.
alert A message or log that a storage unit
generates as the result of error event
collection and analysis. An alert indicates
that a service action is required.
allegiance
For System z products, a relationship that
is created between a device and one or
more channel paths during the processing
of certain conditions. See also implicit
allegiance, contingent allegiance, and reserved
allegiance.
allocated storage
The space that is allocated to volumes but
not yet assigned. Contrast with assigned
storage.
American National Standards Institute (ANSI)
An organization of producers, consumers,
and general interest groups that
establishes the procedures by which
accredited organizations create and
maintain voluntary industry standards in
the United States. (A)
anonymous
In the DS Storage Manager, the label on
an icon that represents all connections
that are using fibre-channel adapters
between the storage unit and hosts but
are not completely defined to the storage
unit. See also anonymous host, pseudo host,
and access-any mode.
anonymous host
Synonym for pseudo host. Contrast with
anonymous and pseudo host.
ANSI See American National Standards Institute.
APAR See authorized program analysis report. (GC)
API See application programming interface.
