DS8000 performance features
The DS8000 series is designed to provide you with high-performance, connectivity,
and reliability allowing your workload to be easily consolidated into a single storage
subsystem.
The following list provides an overview of some of the features that are associated
with the DS8000 series:
POWER5 processor technology
The DS8000 features IBM POWER5 server technology. Depending on
workload, the maximum host I/O operations per second of the DS8100
Model 921 is up to three times the maximum operations per second of the
ESS Model 800. The maximum host I/O operations per second of the
DS8300 Model 922 or 9A2 is up to six times the maximum of the ESS
model 800.
Industry standard fibre channel disk drives
The DS8000 series offers a selection of fibre channel disk drives, including
300 GB drives, allowing a DS8100 to scale up to 115.2 TB of capacity and
a DS8300 to scale up to 192 TB of capacity.
Four-port fibre channel/FICON adapters
These new adapters not only enhance connectivity, but increase
configuration flexibility because the individual ports can be configured to
support fibre channel or FICON.
HOST attachments
The DS8100 offers up to 16 host adapters (64 FCP/FICON ports) and the
DS8300 offers up to 32 host adapters (128 FCP/FICON ports), further
increasing your ability to share your disk storage.
IBM Standby Capacity on Demand
The IBM Standby Capacity on Demand (Standby CoD) offering allows the
installation of inactive disk drives that can be easily activated as business
needs require. With this offering, up to four Standby CoD disk drive sets (64
disk drives) can be factory or field installed into your system. To activate,
you logically configure the disk drives for use—a non-disruptive activity that
does not require intervention from IBM. Upon activation of any portion of
the Standby CoD disk drive set, you must place an order with IBM to initiate
billing for the activated set. At that time, you can also order replacement
Standby CoD disk drive sets.
Online Information Center
The online Information Center is an information database that provides you
the opportunity to quickly familiarize yourself with the major aspects of the
DS8000 and to easily recognize the topics for which you might require more
information. It provides information regarding user assistance for tasks,
concepts, reference, user scenarios, tutorials, and other types of user
information. Because the information is all in one place rather than across
multiple publications, you can access the information that you need more
efficiently and effectively.
Interfaces of the DS8000
The DS8000 provides management interfaces that contain management tools and
utilities to help you increase productivity.
8 DS8000 User’s Guide
IBM TotalStorage DS Storage Manager
The IBM TotalStorage DS Storage Manager is a program interface that is used to
perform logical configurations and Copy Services management functions.
The DS Storage Manager program is installed as a GUI (graphical mode) or as an
unattended (silent mode) installation for the supported operating systems. It can be
accessed from any location that has network access using a Web browser. It offers
you the following choices:
Simulated configuration
You install this component on your PC or the Master Console which
provides the ability to create or modify logical configurations when your
storage unit is disconnected from the network. After creating the
configuration, you can save it and then apply it to a network attached
storage unit at a later time.
Real-time configuration
This component is preinstalled on your HMC. It provides you the ability to
create logical configurations and use Copy Services features when your
storage unit is attached to the network. This component provides you with
real-time (online) configuration support.
DS command-line interface
The IBM TotalStorage DS Command-Line Interface (CLI) enables open systems
hosts to invoke and manage FlashCopy and Metro and Global Mirror functions
through batch processes and scripts.
The command-line interface provides a full-function command set that allows you to
check your storage unit configuration and perform specific application functions
when necessary.
The following list highlights a few of the specific types of functions that you can
perform with the DS command-line interface:
v Check and verify your storage unit configuration
v Check the current Copy Services configuration that is used by the storage unit
v Create new logical storage and Copy Services configuration settings
v Modify or delete logical storage and Copy Services configuration settings
Note:
Yo u cannot install the DS CLI on a Windows 64-bit operating system.
DS Open application programming interface
The DS Open application programming interface (API) is a nonproprietary storage
management client application that supports routine LUN management activities,
such as LUN creation, mapping and masking, and the creation or deletion of RAID5
and RAID10 volume spaces. The DS Open API also enables Copy Services
functions such as FlashCopy and Remote Mirror and Copy (formally known as
peer-to-peer remote copy).
The IBM TotalStorage DS Open API helps integrate DS configuration management
support into storage resource management (SRM) applications, which allow
customers to benefit from existing SRM applications and infrastructures. The DS
Open API also enables the automation of configuration management through
customer-written applications. Either way, the DS Open API presents another option
Chapter 1. Introduction to IBM TotalStorage DS8000 series 9
for managing storage units by complementing the use of the IBM TotalStorage DS
Storage Manager web-based interface and the DS command-line interface.
You must implement the DS Open API through the IBM TotalStorage Common
Information Model (CIM) agent, a middleware application that provides a
CIM-compliant interface. The DS Open API uses the CIM technology to manage
proprietary devices as open system devices through storage management
applications. The DS Open API allows these storage management applications to
communicate with a storage unit.
DS8000 hardware specifics
The DS8000 models offer a high degree of availability and performance through the
use of redundant components that can be replaced while the system is operating.
You can use the DS8000 models with a mix of different operating systems and
clustered and nonclustered variants of the same operating systems.
Contributing to the high degree of availability and reliability are the structure of the
DS8000 storage unit, the host systems it supports, and its processor memory and
processor speeds.
Storage unit structure
The design of the storage unit, which contains the base model and the expansion
models, contributes to the high degree of availability that is associated with the
DS8000. The primary components that support high availability within the storage
unit are the storage server, the processor complex, and the rack power control card.
The storage unit also has redundant fibre switches, with fibre fabric connections to
both processor complexes. The entire power system at all levels is fully redundant.
There are redundant private LAN networks between each storage unit and the
management consoles (even if there is only one management console).
Storage unit
A storage unit consists of a storage server and two or more storage (disk)
enclosures that are packaged in one or more racks with associated power
supplies, batteries, and cooling.
Storage server
A storage server consists of two processor complexes, two or more I/O
enclosures, and a pair of rack power control cards.
Processor complex
A processor complex controls and manages the storage unit to perform the
function of the storage server. The two processor complexes form a
redundant pair such that if either processor complex fails, the remaining
processor complex performs all storage server functions.
Rack power control card
A redundant pair of rack power control (RPC) cards coordinate the power
management within the storage unit. The RPC cards are attached to the
service processors in each processor complex, the primary power supplies
in each rack, and indirectly to the fan/sense cards and storage enclosures
in each rack.
Multi-path subsystem device driver
The IBM TotalStorage Multi-path subsystem device driver (SDD) provides
load balancing and enhanced data availability capability in configurations
with more than one I/O path between the host server and the DS8000
10 DS8000 User’s Guide
series system. Load balancing can help reduce or eliminate I/O bottlenecks
that occur when many I/O operations are directed to common devices that
are using the same I/O path. The SDD also helps eliminate a potential
single point of failure by automatically rerouting I/O operations when a path
failure occurs, thereby supporting enhanced data availability capability.
IBM TotalStorage Management Console
The IBM TotalStorage Management Console is the focal point for configuration,
copy services management, and maintenance activities.
The Management Console is a dedicated workstation that is physically located
(installed) inside your DS8100 and DS8300 and can automatically monitor the state
of your system, notifying you and IBM when service is required. The Management
Console can also be connected to your network to enable centralized management
of your system using the IBM TotalStorage DS Command-Line Interface or the
storage management software that uses the IBM TotalStorage DS Open API.
To provide continuous availability of customer access to the management console
functions, having a second management console is recommended. This second
management console can be provided in two ways:
v External (outside the 2107) - This console is generally installed in the
customer-provided rack. It uses the same hardware as the internal management
console.
v Internal (a second management console that resides within a second 2107) -
This console can be cabled together with the primary internal management
console of the first 2107.’
Host systems that the storage unit supports
The DS8000 storage unit provides a variety of host attachments so that you can
consolidate storage capacity and workloads for open-systems hosts, S/390 hosts,
and eServer
™
zSeries hosts.
The DS8100 Model 921 supports a maximum of 16 host adapters and 4 device
adapter pairs, and the DS8300 Models 922 and 9A2 supports a maximum of 32
host adapters and 8 device adapter pairs.
You can configure the storage unit for any of the following system adapter types
and protocols:
v Fibre-channel adapters, for support of fibre-channel protocol (FCP) and fibre
connection (FICON®) protocol
v Enterprise Systems Connection Architecture
®
(ESCON) adapters
For
fibre-channel attachments, you can establish zones. The zones must contain a
single port that is attached to a system adapter with the desired number of ports
that are attached to the storage unit. By establishing zones, you reduce the
possibility of interactions between system adapters in switched configurations. You
can establish the zones by using either of two zoning methods:
v Port number
v Worldwide port name (WWPN)
You
can configure switch ports that are attached to the storage unit in more than
one zone. This enables multiple system adapters to share access to the storage
Chapter 1. Introduction to IBM TotalStorage DS8000 series 11
unit fibre-channel ports. Shared access to a storage unit fibre-channel port might
come from host platforms that support a combination of bus adapter types and the
operating systems.
Attaching a DS8000 series to an open-systems host with
fibre-channel adapters
You can attach a DS8000 series to an open-systems host with fibre-channel
adapters.
Fibre channel is a 1 Gbps or 2 Gbps, full-duplex, serial communications technology
to interconnect I/O devices and host systems that are separated by tens of
kilometers.
The IBM TotalStorage DS8000 series supports SAN connections at 1 Gbps to 4
Gbps with 2 Gbps host bus adapters. The DS8000 series negotiates automatically
and determines whether it is best to run at 1 Gbps link or 2 Gbps link. The IBM
TotalStorage DS8000 series detects and operates at the higher link speed.
Fibre channel transfers information between the sources and the users of the
information. This information can include commands, controls, files, graphics, video,
and sound. Fibre-channel connections are established between fibre-channel ports
that reside in I/O devices, host systems, and the network that interconnects them.
The network consists of elements like switches, bridges, and repeaters that are
used to interconnect the fibre-channel ports.
Fibre-channel (SCSI-FCP) attached open-systems hosts that the
storage unit supports
You can attach the DS8000 storage unit to fibre-channel (SCSI-FCP) attached
open-systems hosts.
Each storage unit fibre-channel adapter has four ports. Each port has a unique
worldwide port name (WWPN). Yo u can configure the port to operate with the
SCSI-FCP upper-layer protocol. Shortwave adapters and longwave adapters are
available on the storage unit.
Fibre-channel adapters for SCSI-FCP support provide the following configurations:
v A maximum of 64 host ports for DS8100 Model 921 and a maximum of 128 host
ports for DS8300 Models 922 and 9A2
v A maximum of 509 host logins per fibre-channel port
v A maximum of 2000 N-port logins per storage image
v Access to all 63.7KB LUNs per target (one target per host adapter), depending
on host type
v Either arbitrated loop, switched fabric, or point-to-point topologies
The
storage unit supports the following host systems for shortwave fibre-channel

models, adapters, and the operating systems that the storage unit supports.
ESCON-attached S/390 and zSeries hosts that the storage unit
supports
You can attach the DS8000 storage unit to the ESCON-attached S/390 and zSeries
hosts.
With ESCON adapters, the storage unit provides the following configurations:
v A maximum of 32 host ports for DS8100 Model 921 and a maximum of 64 host
ports for DS8300 Models 922 and 9A2
v A maximum of 64 logical paths per port
v Access to 16 control-unit images (4096 CKD devices) over a single ESCON port
on the storage unit
v Zero to 64 ESCON channels; two per ESCON host adapter
v Tw o ESCON links with each link that supports up to 64 logical paths
A DS8100 storage unit supports up to 16 host adapters that provide a maximum
of 32 ESCON links per machine. A DS8300 storage unit supports up to 32 host
adapters that provide a maximum of 64 ESCON links per machine.
Note:
ESCON host channels limit the number of devices per channel to 1024. To
fully access 4096 devices on a storage unit, it is necessary to connect a
minimum of four ESCON host channels to the storage unit. Yo u can access
the devices through a switch to a single storage unit ESCON port. This
method exposes four control-unit images (1024 devices) to each host
channel.
The FICON bridge card in ESCON director 9032 Model 5 enables a FICON bridge
channel to connect to ESCON host adapters in the storage unit. The FICON bridge
architecture supports up to 16 384 devices per channel. This enables you to attach
other control units or other storage units to the same host channel up to the limit
that the host supports.
Chapter 1. Introduction to IBM TotalStorage DS8000 series 13
The storage unit supports the following operating systems for S/390 and zSeries
hosts:
v Transaction Processing Facility (TPF)
v Virtual Storage Extended/Enterprise Storage Architecture (VSE/ESA™)

14 DS8000 User’s Guide
Processor memory
The DS8100 Model 921 offers up to 128 GB of processor memory and the DS8300
Models 922 and 9A2 offer up to 256 GB of processor memory. The Non-Volatile
Storage (NVS) scales to the selected processor memory size, which can also help
optimize performance.
Data management features
The DS8000 storage unit is designed with the following management features that
allow you to securely process and access your data according to your business
needs even if it is 24 hours a day and 7 days a week.
RAID
Redundant array of independent disks (RAID) is a method of configuring multiple
disk drives in a storage subsystem for high availability and high performance.
The collection of two or more disk drives presents the image of a single disk drive
to the system. In the event of a single device failure, data can be read or
regenerated from the other disk drives in the array. With RAID implementation, the
storage unit offers fault-tolerant data storage. The storage unit supports RAID
implementation on the storage unit device adapters. The storage unit supports
groups of disk drive modules (DDMs) in both RAID 5 and RAID 10.
RAID 5
RAID 5 is a method of spreading volume data plus data parity across multiple disk
drives. RAID 5 increases performance by supporting concurrent accesses to the
multiple DDMs within each logical volume.
RAID 10
RAID 10 implementation provides data mirroring from one DDM to another DDM.
RAID 10 stripes data across half of the disk drives in the RAID 10 configuration.
The other half of the array mirrors the first set of disk drives. In some cases, RAID
10 offers faster data reads and writes than RAID 5 because it does not need to
manage parity. However, with half of the DDMs in the group used for data and the
other half used to mirror that data, RAID 10 disk groups have less capacity than
RAID 5 disk groups.
Arrays across loops
The arrays across loops helps prevent data loss.
The storage unit provides arrays across loops on open-systems, S/390, and zSeries
hosts. For RAID 10, arrays across loops provides mirroring across two loops, which
prevents loss of the array during loop failure.
Storage System LPARs (logical partitions)
The DS8300 Model 9A2 exploits LPAR technology, allowing you to run two separate
storage server images.
Each Storage System LPAR has access to:
v 50 percent of the processors
v 50 percent of the processor memory
Chapter 1. Introduction to IBM TotalStorage DS8000 series 15
v Up to 16 host adapters
v Up to 320 disk drives (up to 96 TB of capacity)
With these separate resources, each Storage System LPAR can run the same or
different versions of microcode, and can be used for completely separate
production, test, or other unique storage environments within this single physical
system. This may enable storage consolidations where separate storage
subsystems were previously required, helping to increase management efficiency
and cost effectiveness.
Copy Services
Copy Services is a collection of functions that provides disaster recovery, data
migration, and data duplication functions. Copy Services runs on the IBM
TotalStorage DS8000 storage unit and supports open systems and zSeries
environments.
Many design characteristics and advanced functions of the DS8000 contribute to
protection of your data. DS8000 has a number of advanced Copy Services
functions that are part of the IBM TotalStorage Resiliency family. These functions
are supported also on the previous generation of storage systems called the IBM
TotalStorage Enterprise Storage Server (ESS).
Copy Services include the following types of functions:
v FlashCopy, which is a point-in-time copy function
v Remote mirror and copy functions (previously known as Peer-to-Peer Remote
Copy or PPRC), which includes:
– IBM TotalStorage Metro Mirror (previously known as Synchronous PPRC)
– IBM TotalStorage Global Copy (previously known as PPRC Extended
Distance)
– IBM TotalStorage Global Mirror (previously known as Asynchronous PPRC)
v z/OS Global Mirror (previously known as Extended Remote Copy [XRC])
You
can manage Copy Services functions through a command-line interface called
the IBM TotalStorage DS CLI and a new Web-based interface called the IBM
TotalStorage DS Storage Manager. The DS Storage Manager allows you to set up
and manage the following types of data-copy functions from any point from which
network access is available:
FlashCopy
The FlashCopy feature enables you to create full volume copies of data.
When you set up a FlashCopy operation, a relationship is established
between source and target volumes, and a bitmap of the source volume is
created. Once this relationship and a bitmap are created, the target volume
can be accessed as though all the data had been physically copied. While
a relationship between the source and target volume exists, a background
process copies the tracks from the source to the target volume.
FlashCopy is an optional function. To use it, you must purchase the
point-in-time 2244 function authorization model, which is 2244 Model PTC.
Remote
Mirror and Copy
The remote mirror and copy feature is a flexible data mirroring technology
that allows replication between volumes on two or more disk storage
systems. Yo u can also use this feature for data backup and disaster
recovery.
16 DS8000 User’s Guide
Remote mirror and copy is an optional function. To use it, you must
purchase the remote mirror and copy 2244 function authorization model,
which is 2244 Model RMC.
DS8000 storage units can participate in remote mirror and copy solutions
with the ESS Model 750, ESS Model 800, and DS6000 storage units.
The remote mirror and copy feature can operate in the following modes:
Metro Mirror
Provides real-time mirroring of logical volumes between two
DS8000s that can be located up to 300 km from each other. It is a
synchronous copy solution where write operations are completed on
both copies (local and remote site) before they are considered to be
completed.
Global Copy
Copies data nonsynchronously and over longer distances than is
possible with Metro Mirror. When operating in Global Copy mode,
the source volume sends a periodic, incremental copy of updated
tracks to the target volume instead of a constant stream of updates.
This causes less impact to application writes for source volumes
and less demand for bandwidth resources, while allowing a more
flexible use of the available bandwidth.
Global Mirror
Provides a long-distance remote copy feature across two sites
using asynchronous technology. Global Mirror operations provide
the following benefits:
v Support for virtually unlimited distance between the local and
remote sites, with the distance typically limited only by the
capabilities of the network and the channel extension technology.
This ″unlimited″ distance enables you to choose your remote site
location based on business needs and enables site separation to
add protection from localized disasters.
v A consistent and restartable copy of the data at the remote site,
created with minimal impact to applications at the local site.
v Data currency where, for many environments, the remote site
lags behind the local site on an average of 3 to 5 seconds,
minimizing the amount of data exposure in the event of an
unplanned outage. The actual lag in data currency that you
experience can depend upon a number of factors, including
specific workload characteristics and bandwidth between the
local and remote sites.
v Dynamic selection of the desired recovery point objective, based
upon business requirements and optimization of available
bandwidth.
v Session support whereby data consistency at the remote site is
internally managed across up to eight DS8000 machines that are
located across the local and remote sites.
v Efficient synchronization of the local and remote sites with
support for failover and failback modes, helping to reduce the
time that is required to switch back to the local site after a
planned or unplanned outage.
z/OS Global Mirror
The z/OS Global Mirror function mirrors data on the storage unit to a
Chapter 1. Introduction to IBM TotalStorage DS8000 series 17
remote location for disaster recovery. It protects data consistency across all
volumes that you have defined for mirroring. The volumes can reside on
several different storage units. The z/OS Global Mirror function can mirror
the volumes over several thousand kilometers from the source site to the
target recovery site. DS8000 storage complexes support z/OS Global Mirror
only on zSeries hosts.
With z/OS Global Mirror, you can suspend or resume service during an
outage. Yo u do not have to end your current data-copy session. You can
suspend the session, then restart it. Only data that changed during the
outage needs to be resynchronized between the copies.
The z/OS Global Mirror function is an optional function. To use it, you must
purchase the remote mirror for z/OS 2244 function authorization model,
which is 2244 Model RMZ.
z/OS Metro/Global Mirror (3-site z/OS Global Mirror and Metro Mirror)
This mirroring capability uses z/OS Global Mirror to mirror primary site data
to a location that is a long distance away and also uses Metro Mirror to
mirror primary site data to a location within the metropolitan area. This
enables a z/OS 3-site high availability and disaster recovery solution for
even greater protection from unplanned outages.
The z/OS Metro/Global Mirror function is an optional function. To use it, you
must purchase both of the following functions:
v Remote mirror for z/OS (2244 Model RMZ)
v Remote mirror and copy function (2244 Model RMC) for both the primary
and secondary storage units
FlashCopy
The IBM TotalStorage FlashCopy feature provides a point-in-time copy capability for
logical volumes. FlashCopy creates a physical point-in-time copy of the data, with
minimal interruption to applications, and makes it possible to access immediately
both the source and target copies.
The primary objective of FlashCopy is to create a copy of a source volume on the
target volume. This copy is called a point-in-time copy. When you initiate a
FlashCopy operation, a FlashCopy relationship is created between the source
volume and target volume. A FlashCopy relationship is a ″mapping″ of a FlashCopy
source volume and a FlashCopy target volume. This mapping allows a point-in-time
copy of the source volume to be copied to the target volume. The FlashCopy
relationship exists between the volume pair from the time that you initiate a
FlashCopy operation until the DS8000 copies all data from the source volume to the
target volume or until you delete the FlashCopy relationship, if it is a persistent
FlashCopy.
The point-in-time copy that is created by FlashCopy is typically used when you
need a copy of the production data to be produced with minimal application
downtime. It can be used for online back up, testing of new applications, or for
creating a database for data-mining purposes. The copy looks exactly like the
original source volume and is an instantly available, binary copy.
FlashCopy supports the following copy options:
Data Set FlashCopy
Data Set FlashCopy allows a FlashCopy of a data set in a zSeries
environment.
18 DS8000 User’s Guide
Multiple relationship FlashCopy
Multiple relationship FlashCopy allows a source to have FlashCopy
relationships with multiple targets simultaneously. This flexibility allows you
to establish up to 12 FlashCopy relationships on a given logical unit number
(LUN), volume, or data set, without needing to first wait for or cause
previous relationships to end.
Refresh target volume (also known as incremental FlashCopy)
Refresh target volume provides the ability to ″refresh″ a LUN or volume
involved in a FlashCopy relationship. When a subsequent FlashCopy
operation is initiated, only data that updates the target and the source to the
same point-in-time state is copied. The direction of the ″refresh″ can also
be reversed. The LUN or volume that was defined as the target can now
become the source for the LUN or the volume that was defined as the
source (now the target).
Persistent FlashCopy
Persistent FlashCopy allows the FlashCopy relationship to remain even
after the FlashCopy operation completes. You must explicitly delete the
relationship.
Establish FlashCopy on existing Remote Mirror and Copy source
The establish FlashCopy on an existing Remote Mirror and Copy source
volume option allows you to establish a FlashCopy relationship where the
target volume is also the source of an existing remote mirror and copy
source volume. This enables you to create full or incremental point-in-time
copies at a local site and then use remote mirroring commands to copy the
data to the remote site.
This feature is represented by the Establish target on existing Metro
Mirror source selection in the GUI.
Consistency group commands
Consistency group commands allow the DS8000 to freeze I/O activity to a
LUN or volume until you issue the FlashCopy consistency group command.
Consistency groups help create a consistent point-in-time copy across
multiple LUNs or volumes, and even across multiple DS8000 systems. This
function is available through the use of command-line interface commands.
Inband commands over remote mirror link
In a remote mirror environment, inband commands are issued to a source
volume of a remote mirror and copy volume pair on a local storage unit and
sent across paths (acting as a conduit) to a remote storage unit to enable a
FlashCopy pair to be established at the remote site. This eliminates the
need for a network connection to the remote site solely for the management
of FlashCopy. This function is available through the use of command-line
interface commands.
Disaster recovery using Copy Services
One of the main reasons for using Copy Services functions is in preparation for a
possible disaster by backing up, copying, and mirroring your data at the production
and recovery sites.
You can create a disaster recovery solution using any of the following functions.
These functions help improve a disaster recovery process by allowing a much
shorter recovery time with little or no data loss.
Chapter 1. Introduction to IBM TotalStorage DS8000 series 19
Note: In a remote mirror and copy environment, when two storage units are set up
in two geographically distinct locations, we refer to the sites as Site A (the
production site) and Site B (the recovery site).
Failover and failback operations
A failover is the process of temporarily switching production to a backup
facility (normally your recovery site) following a planned outage, such as a
scheduled maintenance period or an unplanned outage, such as a disaster.
A failback operation is the process of returning production to its original
location. These operations use remote mirror and copy functions to help
reduce the time that is required to synchronize volumes after sites are
switched during planned or unplanned outages.
Global Mirror
The Global Mirror function provides a two-site extended distance remote
copy option for disaster recovery and backup solution for the zSeries and
open systems environments. This solution is based on existing Global Copy
and FlashCopy functions. With Global Mirror, the data that the host writes to
the storage unit at the production site is asynchronously shadowed to the
storage unit at the recovery site. Global Mirror operates over high-speed,
Fibre Channel communication links and is designed to maintain a consistent
and restartable copy of data at a recovery site that can be located at
virtually unlimited distance from the production site.
Comparison of licensed functions
A key decision that you must make in planning for a disaster is deciding which
licensed functions to use to best suit your environment.
Table 2 provides a brief summary of the characteristics of the Copy Services
features that are available for the storage unit.

Parallel Access Volumes
The use of parallel access volumes (PAVs) enables a single zSeries server to
simultaneously process multiple I/O operations to the same logical volume, which
can help to significantly reduce device queue delays. This is achieved by defining
multiple addresses per volume.
With dynamic parallel access volumes, the assignment of addresses to volumes is
automatically managed to help the workload meet its performance objectives and
minimize overall queuing.
You must configure both your storage unit and operating system to use PAVs. You
can use the logical configuration definition to define PAV-bases, PAV-aliases, and
their relationship in the storage unit hardware. This unit address relationship creates
a single logical volume, allowing concurrent I/O operations.
The storage unit supports concurrent or parallel data transfer operations to or from
the same volume from the same system or system image for S/390 or zSeries
hosts. An S/390 with PAV software support enables multiple users and jobs to
simultaneously access a logical volume. Read and write operations can be
accessed simultaneously to different domains. (The domain of an I/O operation is
the specified extents to which the I/O operation applies.)
DS8000 limitations
The following list describes known limitations for the DS8000.
v The 65,520 cylinder 3390 volume is not supported with z/OS Global Mirror and
z/OS Metro/Global Mirror.
v The amount of physical capacity within a 2107 system that can be logically
configured for use will be enforced by the 2107 licensed machine code (LMC) to
maintain compliance with the extent of IBM authorization established for licensed
functions activated on the machine. The 2107 LMC will not allow the logical
configuration of physical capacity beyond the extent of IBM authorization (except
when activating Standby CoD capacity).
v The deactivation of an activated licensed function, or a lateral change or
reduction in the license scope, is a disruptive activity and requires a machine IML
(Model 921 and Model 922) or reboot of the affected image (Model 9A2). A
lateral change is defined as changing the license scope from fixed block (FB) to
count key data (CKD) or from CKD to FB. A reduction is defined as changing the
license scope from all physical capacity (ALL) to only FB or only CKD capacity.
v The following activities are disruptive:
Chapter 1. Introduction to IBM TotalStorage DS8000 series 21
– Model conversions. In addition, data may not be preserved during the model
conversion.
– Field attachment of the first Model 92E expansion unit to a Model 922.
– Field attachment of the first Model 9AE expansion unit to a Model 9A2.
– Removal of an expansion unit model from the base unit model. Data may not
be preserved during this activity.
v
Some DS8000 functions are not available or supported in all environments. You
can find current information about supported environments, prerequisites, and
minimum operating systems levels at the following IBM Web site:
http://www.ibm.com/servers/storage/disk/ds8000/interop.html
Planning data migration
The planning and methods of data migration for the DS8000 vary by environment.
The DS8000 supports over 90 operating systems. Yo u can migrate data to a
storage unit from these host and operating system environments.
When you plan for data migration, consider the following factors:
Note:
The following lists do not cover every possibility. They provide a high-level
view of some of the tools and factors that you can consider when moving
data.
v The system:
– Is it UNIX based? You will probably use some variation of a logical volume
manager.
– Is it a zSeries or S/390? Yo u will probably use IBM
®
TotalStorage
®
Global
Mirror, Remote Mirror and Copy (when available).
– Is it z/OS? Yo u will probably use DFDSS, though there are many choices.
– Is it VM? Yo u might use DASD Dump Restore or PTAPE.
– Is it VSE? Yo u might use the VSE fastcopy or ditto commands.
Your system administrator selects the data migration method that is the best
compromise between efficiency and impact on the users of the system.
v The storage unit:
– Are the storage units involved the same with the same level of licensed
management code?
– Are the storage units different? In which case you want to ensure that the new
configuration is large enough to accommodate the existing data. You also
want to ensure that the virtual disks are similar in configuration to the disk
drives that they are replacing.
v Time and complexity involved:
– Typically data migration requires that updates or changes cease while the
movement occurs. Also, depending on the amount of data that you are
moving and your migrating method, data could be unavailable for an extended
period of time, perhaps several hours.
– Could the complexity and time involved require the services of IBM through
International Global Services? Contact your IBM representative for more
information.
How to select a data migration method
Your system administrator selects the data migration method that is the best
compromise between efficiency and impact on the users of the system.
22 DS8000 User’s Guide
Most methods of data migration affect the everyday operation of a computer
system. When data is moved, the data must be in a certain state, typically requiring
that updates or changes cease while the movement occurs. Depending on the
amount of data that you are moving and your migrating method, data could be
unavailable for an extended period of time, perhaps several hours. The following
factors might contribute to the migration time:
v Creating new logical volumes or file systems
v Modifying configuration files
v Receiving integrity checks
The
following items are more than likely among the topics considered by your
system administrator to determine the best method to use to migrate your data:
v Management software provides simple robust methods that you can generally
use during production without disturbing users.
v The AIX logical volume manager (LVM) provides methods that you can use at
any time without disrupting user access to the data. You might notice a small
performance degradation, but this is preferable to shutting down databases or
requiring users to log off the system.
Notes:
– AIX and HP-UX 11 .xx ship with logical volume management (LVM)
software as part of the base operating system. LVM provides
complete control over all disks and file systems that exist on an AIX
system. HP-UX has similar volume management software.
– Sun Microsystems has a basic volume management product called
Solstice, which is available for the Solaris systems.
– Linux systems also use the LVM.
v Methods that use backup and restore procedures generally have the most impact
on the system usage. They require that databases and file systems be in
quiescent states to ensure a valid snapshot of the data.

Windows Server Parameters window
You can change the default values by supplying the following information:
a. Host Name — The host name of the physical machine where the DS
Storage Manager Server is installed. The host name must resolve to a
physical network node on the server. When multiple network cards exist in
the server, the host name or IP address must resolve to one of the network
cards. The value that you specify for the host name is used as the value of
the hostName property in WebSphere Application Server configuration files.
Specify the host name value in one of the following formats:
v The fully qualified domain name servers (DNS) host name string; for
example, xmachine.manhattan.ibm.com.
v The default short DNS host name string; for example, xmachine.
v The numeric IP address; for example, 9.127.255.3.
v The generic name localhost or its equivalent IP address; for example,
127.0.0.1.
Note:
The specified value for the host name is stored by WebSphere
Application Server into its internal configuration files. If you specified
the host name in the fully qualified form or the short host name
string, do not change the host name after the DS Storage Manager
Server installation. If you do, the host name and the name that you
specified for the configuration file no longer match. If you do change
the host name, you must manually edit all the WebSphere
Application Server configuration files that contain references to the
old name to reflect the new name. If you specified the host name in
the form of the numeric IP address, you must use a fixed IP address
for the computer (you cannot use DHCP to obtain a dynamic IP
address for it). The above restrictions do not exist if you specified
the host name in the form as localhost.
b. HTTP Port — The port number that the DS Storage Manager Server uses.
The port number must be a port that is not being used by another process
on the system. After the DS Storage Manager Server is installed, you must
Chapter 2. Installing the DS8000 Storage Manager 31
include this port number in the URL to access the console. That URL is the
protocol name, plus the fully qualified host name, plus the port, plus
DS8000/console; for example, http://myhost.com:8451/DS8000/console.
c. HTTPS Port — The port that the DS Storage Manager Server uses for
secure HTTP transport (HTTPS).
d. Bootstrap/RMI Port — The port that the DS Storage Manager Server uses
for the bootstrap port.
e. SOAP Port — The port that the DS Storage Manager Server uses for
Simple Object Access Protocol (SOAP).
f. Server help Port — The port for the Eclipse help Server. This port is the
one that the help system (based on Eclipse technology) uses to receive
requests for help files.
Note:
The values that are used in the Server Parameters window fields must
not conflict with existing port assignments that are already on the
system or reserved for use by another application.
11. Click Next after you have ensured that all the input fields on the Server
Parameters window are complete. The SSL Configuration window is displayed.
This window allows you to supply the fully qualified name of the two server key
files generated before or during the DS8000 Storage Manager installation.
Windows SSL Configuration window
12. Follow the instructions on the window.
a. First, designate whether you want to generate a new SSL certificate by
selecting Generate the self-signed certificates during installation. This
is the most likely selection when you are installing DS8000 Storage
Manager for the first time. You can also select Use existing SSL
certificates. This choice is most likely made when the key files already
exist and you do not want to generate new key files.
b. Complete the rest of the fields on the window. Provide the fully qualified
path to the key file and trust file by using the Browse button. The key file
and trust file are identified by an extension of .jks.
32 DS8000 User’s Guide
c. Supply a password for each file. The password must be a minimum of
six-characters and it cannot contain any blanks.
13.
Click Next to continue the installation process. If you have selected Generate
the self-signed certificates during installation, the Generate Self-Signed
Certificate window is displayed. If you selected Use existing SSL certificates,
the Installation Confirmation window is displayed.
Note: When you select Generate self-signed certificates during installation
and the key files already exist on the system at the specified location,
clicking Next causes a message to display. It asks you to designate
whether you want to have the system delete existing application server
certificates if they exist on the location and to generate others. The
default is NO which means keep the existing application server
certificates.
Windows Generate Self-Signed Certificate window
14. Complete each of the input fields with the required information. Use the
following as a guide to provide the needed information.
Keystore alias
This is the alias for the self-signed certificate. It uniquely identifies the
certificate within the keystore file. It is a good practice to use a unique
name related to the server name.
Key size
Two key sizes are available, 512 and 1024. 1024 is the default.
Common name
This name is the primary, universal identity for the certificate. If your
system contains the secured WebSphere environment, this name must
be valid in the configured user registry.
Organization name
The name of your company
Organization unit (optional)
The name of a department or division within your company. Remember
Chapter 2. Installing the DS8000 Storage Manager 33
that you are building a profile for the certificate. As a security measure
the more specific the information the more secure your system.
Locality (optional)
The city or location where your company resides.
State (optional)
The state or province where your company resides.
Country or region
The two-character designator that identifies the country where your
company is located. Use the pull-down menu to make this selection.
Validity period (days)
Specifies the lifetime of the certificate in days.
The information that you provide is used to build a profile for the certificate.
This information is used during identity processing to ensure validation of any
processing that is occurring. It is part of the security measures that are used
during SSL connectivity.

1) DS Storage Manager Server Installation Progress window
2) DS Network Interface Server Installation Progress window
Note:
Yo u can click Cancel (not recommended) during the DS Network
Interface Server installation process. The process does not stop
immediately when the Cancel button is clicked. Rather, the process
continues to install all the files that are associated with this part of
the installation. These files remain installed and are not reinstalled
upon reactivation of the installation process.
A confirmation message is displayed that asks you to confirm that
you want to cancel the installation.
c. The Components Installation Progress (displaying the installation or
upgrade progress of the DS Storage Manager product applications) is
displayed after the servers have been installed or upgraded.
Note:
Yo u can click Cancel (not recommended) during the components
installation process. The installation process stops immediately
when the Cancel button is clicked. A window with a confirmation
message is displayed. For a new installation, when you confirm that
you want to stop the process, all the files that have been copied up
to the point that the Cancel button was clicked are uninstalled. You
then are exited from the installation process.
When
this part of the installation is completed, the system starts both servers:
first the DS Network Interface Server and then the DS Storage Manager
Server. Wait for the servers to be started before going to the next step. When
the servers have been started, the Installer Finish window is displayed.
17. Click Finish to exit the installation process. When the installation process

Installing the IBM TotalStorage DS Storage Manager on the Windows
operating system in unattended (silent) mode
Use the following steps to install the IBM TotalStorage DS Storage Manager in your
Windows environment using the unattended (silent) mode. When you are installing
on a DS8000 storage unit, you are generally installing the offline management type.
This management type allows you to plan and construct storage unit configurations
without being connected to the network. However, you cannot use the Copy
Services or parallel access volumes (PAVs) features while disconnected from the
network.
Before you install the IBM TotalStorage DS Storage Manager, verify that the
prerequisite software and hardware are installed on your system. The installation
program checks for prerequisites and stops if any prerequisites are missing.
Note: The DS Storage Manager is not supported on any Windows 64-bit operating
system.
The unattended (silent mode) installation option allows you to run the installation
program unattended. Use this method of installation to customize a response file
and to issue a command from a command prompt window. The response file is a
template on the IBM TotalStorage DS Storage Manager CD.
Perform the following steps to install the IBM TotalStorage DS Storage Manager in
your Windows environment using the unattended mode:
1. Log on to your Windows system as an administrator.
2. Insert the IBM TotalStorage DS Storage Manager installation CD into the
CD-ROM drive. If the interactive mode starts, click the Exit selection on the
LaunchPad window to exit.
3. Locate the response file (responsefile.txt) in the root directory of your CD and
copy it to a directory of your choosing on your system, or open a command
prompt window and generate the template response file.
To generate the template response file, perform the following steps:
a. Ensure that your command prompt is located at the root directory of the
CD-ROM drive.
b. Type setup.exe -options-template <responsefile-
path>\<responsefile>, where responsefile-path is the path where you
want the response file to be created, and responsefile is the name of the
response file that you want to create.
c. Press the Enter key and wait for the program to create the response file.
4. Open the response file using a text editor and modify the default options with
the values that you want.
Follow these guidelines when you modify the default options:
v Remove the three # characters from the beginning of each line that contains
a parameter (if you generated the response file as shown before). Change
the parameter default value to the value that you want for that option. Yo u
must enclose all values in double quotation marks (″<value>″).
v Verify that all paths generated or modified in the response file are correct.
There are some cases when the generated file displays an incorrect string
representing the path of the installation location. For example, the parameter
″-P installLocation = ″C:Program FilesMy Product″″ is wrong and must be
″-P product.installLocation = ″<directory where you want the DS Storage
Manager installed>″″

|
|
v Ensure that the entered values for the ports values are available and not
used by other applications on your system. Use the command ″netstat -a″ to
verify the ports in use on your system.
v Specify two passwords for the SSL keys files. These passwords must
observe the following criteria:
– The passwords must contain at least 6 characters.
– Use the following options within the responsefile.txt file to set these
options:
- For the keystore use:
-W wasSslConfiguration.keystorePassword="your_keystore_password"
- For the truststore use:
-W wasSslConfiguration.truststorePassword="<your_truststore_password>"
Note: These options do not have default values. If you do not set
these values, the installation process fails.
5. Save the modifications to the response file.
6. Type the following command at the command prompt and press the Enter key
on your keyboard to start the installation process in silent mode: setup.exe
-options <responsefile-path>\<responsefile> -silent where
v responsefile-path — represents the path where the response file resides.
v responsefile — represents the relative name of the response file that you
used or created (for example, responsefile.rsp or responsefile.txt).
7. Wait for the installation program to install the product. This can take 5 - 10
minutes.
Note: During this processing, the installation process checks to see if the DS
Storage Manager server and DS Network Interface Server are already
installed and if they are the current version or have to be upgraded. If
they are already installed and need to be upgraded, the installation
process performs this function using the already set values from the
previous server installation, found on the system in the server
configuration files, for all the associated values. The specified values in
the response file are ignored.
8. Check the install log file for any possible error messages. This file is located in
the xxx\logs\install.log directory, where xxx is the destination directory where
the IBM TotalStorage DS Storage Manager is installed.
9. Start the IBM TotalStorage DS Storage Manager, if no errors are evident.
10. Perform the postinstallation tasks when the DS Storage Manager has been
installed successfully. Yo u can access the instructions for the postinstallation
tasks from the postinstallation.txt file, in the doc directory on the product CD.
The following is an example of the template response file that is created when you
process the previous steps.

Linux Server Parameters window
a. Host Name — The host name of the physical machine where the DS
Storage Manager Server is installed. The host name must resolve to a
physical network node on the server. When multiple network cards exist in
the server, the host name or IP address must resolve to one of the network
cards. The value that you specify for the host name is used as the value of
the hostName property in WebSphere Application Server configuration files.
Specify the host name value in one of the following formats:
v The fully qualified domain name servers (DNS) host name string; for
example, xmachine.manhattan.ibm.com.
v The default short DNS host name string; for example, xmachine.
v The numeric IP address; for example, 9.127.255.3.
v The generic name localhost or its equivalent IP address; for example,
127.0.0.1.
Note:
The specified value for the host name is stored by WebSphere
Application Server into its internal configuration files. If you specified
the host name in the fully qualified form or the short host name
string, do not change the host name after the DS Storage Manager
Server installation. If you do, the host name and the name that you
specified for the configuration file no longer match. If you do change
the host name, you must manually edit all the WebSphere
Application Server configuration files that contain references to the
old name to reflect the new name. If you specified the host name in
the form of the numeric IP address, you must use a fixed IP address
for the computer (you cannot use DHCP to obtain a dynamic IP
address for it). The above restrictions do not exist if you specified
the host name as localhost.
b. HTTP Port — The port number that DS Storage Manager Server uses.
The port number must be a port that is not being used by another process
on the system. After DS Storage Manager Server is installed, you must
include this port number in the Web address for opening the console. This

Web address is the protocol name, plus the fully qualified host name, plus
the port, plus DS8000/Console. An example is
http://myhost.com:8451/DS8000/Console
c. HTTPS Port — The port that DS Storage Manager Server uses for secure
HTTP transport (HTTPS).
d. Bootstrap/RMI Port — The port that DS Storage Manager Server uses for
bootstrap port.
e. SOAP Port — The port that DS Storage Manager Server uses for Simple
Object Access Protocol (SOAP).
f. Server help port — The port for the Eclipse help Server. This is the port
that the help system (based on Eclipse technology) uses to receive
requests for help files.
Note:
The values used in the Server Parameters window fields must not
conflict with existing port assignments that are already on the system or
reserved for use by another application.
14. Click Next when the Server Parameters window is complete. The SSL
Configuration window is displayed. This window allows you to supply the fully
qualified name of the two server key that are files generated before or during
the DS8000 Storage Manager installation.
Linux SSL Configuration window
15. Follow the instructions on the window.
a. First, designate whether you want to generate a new SSL certificate by
selecting Generate the self-signed certificates during installation. This
is the most likely selection when you are installing the DS8000 Storage
Manager for the first time. You can also select Use existing SSL
certificates. This choice is most likely made when the key files already
exist and you do not want to generate new key files.
b. Complete the rest of the fields on the window. Provide the fully qualified

16. Click Next to continue the installation process. If you have selected Generate
the self-signed certificates during installation, the Generate Self-Signed
Certificate window is displayed. If you selected Use existing SSL certificates,
the Installation Confirmation window is displayed.
Note: When you select Generate self-signed certificates during installation
and the key files already exist on the system at the specified location,
clicking Next displays a message. The message asks you to designate
whether you want to have the system delete existing application server
certificates if they exist on the location and to generate others. The
default is NO, which means that you want to keep the existing
application server certificates.

installation process. The installation process stops immediately
when the Cancel button is clicked. A window with a confirmation
message is displayed. For a new installation, when you confirm that
you want to leave, all the files that have been copied up to the point
that the Cancel button was clicked are uninstalled. You then are
exited from the installation process.
When
this part of the installation is completed, the system starts both servers:
first the DS Network Interface Server and then the DS Storage Manager
Server. Wait for the servers to be started before going to the next step. When
the servers have been started, the Installer Finish window is displayed.
20. Click Finish to exit the installation process. When the installation wizard exits,

Linux DS8000 Storage Manager Installer Finish window
21. If the Finish window indicates that the installation failed, check the installation
log for error messages. The installation log is located in xxx/logs/install.log,
where xxx is the destination directory where the IBM TotalStorage DS Storage
Manager is installed.
Errors fall into two categories: system or incorrect values that are designated
during the install process. Use the following guidelines to correct these errors:
v If the error is due to a system problem, correct it and reinstall the GUI using
either the graphical or silent mode of install.
v If the error is due to a wrong installation parameter value, restart the
installation using the steps that are described in this procedure or the steps
that are described in the silent mode install. Navigate to the Console Server
Parameters window and insert the correct values. Then finish the
installation.
22.
Check the postinstallation instructions after the installation has completed. The
postinstallation.txt file is displayed immediately after the installation of the DS
Storage Manager finishes processing. If the postallation.txt file does not
display, click the Post installation tasks link on the LaunchPad window to
access these instructions. These instructions provide reminders and the steps
to help you start using the DS Storage Manager.
23. Exit the LaunchPad program by clicking Exit on the LaunchPad window.
24. Type the following command when you are finished using the IBM TotalStorage
DS Storage Manager CD and want to remove it from your computer: # umount
/mnt/cdrom where /mnt/cdrom is where the CD is mounted.
Installing the IBM TotalStorage DS8000 Storage Manager on the Linux
operating system in unattended (silent) mode
You can install the IBM TotalStorage DS Storage Manager in your Linux
environment using the unattended (silent) mode.
Chapter 3. Installing on the Linux operating system 63
The unattended (silent) installation option allows you to run the installation program
unattended. Use this method of installation to customize a response file and to
issue a command from a command prompt window. The response file is a template
on the IBM TotalStorage DS Storage Manager CD.
Perform the following steps to install the IBM TotalStorage DS Storage Manager in
your Linux environment using the unattended mode:
1. Log on as a user with root authority.
2. Create a mount point or choose an existing mount point.
3. Determine where you want to mount the DS8000 Storage Manager CD. For
example, imagine you have decided to mount the CD in a CD-ROM drive
known as /dev/cdrom at mount point /mnt/cdrom. When the time comes for you
to mount the CD in this drive, perform the following steps:
a. Insert the CD in the CD-ROM drive.
b. Type the following command at the command prompt: # mount -o ro
/dev/cdrom /mnt/cdrom
4. Choose the destination paths for the DS8000 Storage Manager components
and be sure you have enough available space on the chosen destination. The
installation program (installer) provides a default installation location
(/opt/IBM/DS8000StorageManager) for the component. Yo u can override this
by using the product.installLocation parameter (option) from the response file
used by the silent installation.
5. Change the current directory to the mount point for the CD-ROM drive. For
example, if the CD was mounted at the /mnt/cdrom mount point, type the
following command: # cd /mnt/cdrom
6. Read the README.txt file located on the DS8000 Storage Manager CD to
check for information that might supersede the information in these installation
instructions.
7. Copy the template response file (responsefile.txt) from the root directory of the
product CD to a location on your system in order to modify it according to your
installation parameters. The response file contains all the installation
parameters whose values can be modified during an interactive installation.
8. Modify your copy of the response file in accordance with the following
guidelines:
a. Open the response file using a text editor. Remember that you must
enclose all values in double quotation marks (″<value>″).
b. Replace the parameters values with the appropriate values for each
uncommented option.
c. For the port values, ensure that they are free for use (not used or reserved
for use by other applications on your system). Use the command netstat
-an to verify the ports that are in use on your system.
d. Yo u must specify two passwords for the SSL keys files. These passwords
must observe the following criteria:
v The passwords must contain at least 6 characters.
v Use the following options within the responsefile.txt file to set these
options:
– For the keystore use:
-W wasSslConfiguration.keystorePassword="your_keystore_password"
– For the truststore use:
64 DS8000 User’s Guide
-W wasSslConfiguration.truststorePassword="<your_truststore_password>"
Note: These options do not have default values. If you do not set the
values, the installation process fails.
e.
Save the changes made to the response/options file.
9. Type ./setup.linux -options <responsefile-path>/<responsefile> in the same
Command Prompt window in which you changed the current directory to the
root of the CD, to start the DS8000 Storage Manager installation program in
silent mode.
<responsefile-path>
Designates the path where the response file was created before
<responsefile>
Designates the relative name of the response file that you created and
modified before
10.
Wait for the DS8000 Storage Manager installation program to install the
product. This can take 5 - 10 minutes.
Note: During this processing, the installation process checks to see if the DS
Storage Manager server and DS Network Interface Server are already
installed and if they are the current version or need to be upgraded. If
they are already installed and need to be upgraded, the installation
process performs this function using the already set values from the
previous installation, found on the system in the server configuration
files, for all the associated values. The specified values in the response
file are ignored.
11. Review the log file for any possible error messages, after the installation
program completes. If there are no errors, the installation program completed
successfully. The log file is located in xxx/logs/install.log, where xxx is the
destination directory where the DS8000 Storage Manager was installed. The
install.log file contains a trace of the installation actions.
12. Perform the postinstallation tasks after the installation has completed. Yo u can
read the instructions for the postinstallation tasks in the postinstallation.txt in
the doc directory on the product CD.
The following is an example of the template response file that is created when you
process the previous steps.

Upgrading the IBM TotalStorage DS Storage Manager on a Linux
operating system
Use this process to upgrade the DS Storage Manager to the latest level.
Note: During the upgrade process, do not interrupt the program by abnormal
methods, because an interruption can cause unpredictable effects in the
system. Abnormal methods include using CTRL-C, closing the launchpad
window which is open behind the upgrade windows, or shutting down the
power source. To interrupt the upgrade process normally, use the Cancel
button displayed on an upgrade window.
Perform the following steps to upgrade the IBM TotalStorage DS Storage Manager.
1. Log on as a user with root authority.
2. Create a mount point or choose an existing mount point.
3. Determine where you want to mount the DS8000 Storage Manager CD. For
example, imagine you have decided to mount the CD in a CD-ROM drive
known as /dev/cdrom at mount point /mnt/cdrom. When the time comes for you
to mount the CD in this drive, perform the following steps:
a. Insert the CD in the CD-ROM drive.
b. Type the following command at the command prompt: # mount -o ro
/dev/cdrom /mnt/cdrom
4. Choose the destination paths for the DS8000 Storage Manager components
and be sure that you have enough space available on the chosen destination.
The upgrade program (installer) provides a default installation location
(/opt/IBM/DS8000StorageManager) for the component. Yo u can override the
default installation location by using the installer browse function. When you
click Next, the installer analyzes the available space for the location that you
provide. If there is not enough space, you cannot proceed to the next panel in
the upgrade process.
5. Change the current directory to the mount point for the CD-ROM drive. For
example, if the CD was mounted at the /mnt/cdrom mount point, type the
following command: # cd /mnt/cdrom.
6. Run the wizard launcher, launchpad_linux, by typing the following command: #
./launchpad_linux. The upgrade in graphical mode begins with a LaunchPad
facility to launch the upgrade program wizard.
