CHAPTER
1
Introduction
The Sun StorEdge 3900 and 6900 series storage subsystems are complete
preconfigured storage solutions. The Sun StorEdge 3900 series provides two
different configurations for the direct attach storage (DAS) environment. The Sun
StorEdge 6900 series also has two configurations that can be used in the Storage
Area Network (SAN) arena.
This chapter is organized as follows:
■ “Overview” on page 1
■ “Architecture” on page 7
■ “System-Level Support Information” on page 9
■ “Features” on page 9
Overview
The Sun StorEdge 3900 and 6900 series storage subsystems provide midrange and
enterprise customers with the following features:
■ Modular storage elements that can be incrementally expanded in a predefined
footprint
■ Logical unit number (LUN) segmenting or carving for storage consolidation (This
is available only on the Sun StorEdge 6900 series.)
■ LUN security access (masking) for the storage consolidation models (This is
available only on the Sun StorEdge 6900 series.)
■ Fibre Channel (FC) interface
■ Sun-tested and supported preconfigured components packaged for specific
storage solutions
■ A high degree of data availability in a unit that reduces cost of ownership

Page 20
A small server, referred to as the Storage Service Processor, is included in each
subsystem and provides support for monitoring and configuration, upgrades of
firmware, and software and diagnostic tools to support effective fault isolation. The
Storage Service Processor supports the Sun StorEdge
SM
Remote Response service,
which provides remote monitoring and serviceability. Failure to add the optional
Sun StorEdge Remote Response software requires that the customer configure an
alternate way to communicate with the Storage Service Processor through a local
network.

Features
The following are features available on both the Sun StorEdge 3900 and 6900 series:
■ Installation—The Sun StorEdge 3900 and 6900 series are delivered as minimum-
setup-required storage subsystems. The Sun StorEdge T3+ array partner group
logical units (LUNs) are preconfigured at the factory.
Chapter 1 Introduction 9
Page 28
■ RAID Striped Data with Standby Hot Spare—Internal Sun StorEdge T3+ array
LUNs are preconfigured as RAID 5 (8 drives, plus a standby hot spare).
Configuration tools are provided on the Service Processor that enable internal
configuration of the Sun StorEdge T3+ arrays to be changed to a limited set of
configurations. Preconfigured LUNs comprising 36-Gbyte disk drives are 236
Gbytes each, while preconfigured LUNs comprising 73-Gbyte disk drives provide
477 Gbytes each.
■ Bandwidth—All of the storage subsystems use Fibre Channel technology to
provide the best available bandwidth. Current FC technology offers 1.06 Gbit/
second transfers (~ 80 Mbytes/second average). The actual bandwidth delivered
might be less, depending on the configuration.
■ Capacity—The storage subsystems that have 36-Gbyte disk drives offer a
minimum of 648 Gbytes and a maximum of 1.9 to 5.8 Tbytes of disk space,
depending on the model selected. The subsystem has a footprint no larger than
12.29 square feet.
The storage subsystems that have 73-Gbyte disk drives offer a minimum of 1.3
Tbytes and a maximum of 3.9 to 11.7 Tbytes of disk space, depending on the
model selected. The subsystem has a footprint no larger than 12.29 square feet.
■ Data Path Redundancy—All of the storage subsystems provide full data path
redundancy with no data path component as a single point of failure, offering
24x7 data availability. Redundant components include the Fibre Channel
switches, Sun StorEdge T3+ array storage bricks, virtualization engines (on Sun
StorEdge 6900 series only), and dual Power Distribution Units (PDUs).
■ Host Managed Multipathing—All of the storage subsystems present two
physical I/O paths to devices on each host. Host software is required to manage
the I/O utilization of the presented I/O paths. Such software includes, but is not
limited to, either Sun StorEdge Traffic Manager (MPxIO) software or VERITAS
Dynamic Multi-Pathing (VxDMP).

CHAPTER
2
Component Descriptions
This chapter offers an overview of the components of the Sun StorEdge 3900 and
6900 series storage subsystems. This overview includes a listing of the hardware and
software used by the storage subsystems.
This chapter is organized as follows:
■ “Hardware Component Descriptions” on page 13
■ “Software Component Descriptions” on page 17
Hardware Component Descriptions
The hardware building blocks for the Sun StorEdge 3900 and 6900 series include:
■ Storage Service Processor
■ Virtualization engine (Sun StorEdge 6900 series only)
■ Customer management connection
■ Storage devices
■ Ethernet hub
■ Fibre Channel switches
■ Sun StorEdge expansion cabinet
Storage Service Processor
The Storage Service Processor is a Netra™ X1 server. The Netra is delivered as part
of the Sun StorEdge 3900 and 6900 series and provides a 500-MHz, 64-bit
UltraSPARC™ processor, 512 Mbytes of memory, and a 40-Gbyte IDE internal drive.
13
Page 32
The Storage Service Processor is responsible for the following:
■ Monitoring the components in the Sun StorEdge 3900 and 6900 series.
■ Fault isolation, verification, and notification of a FRU that is failing.
■ Some limited non-mission critical-configuration functions including configuration
of the Sun StorEdge T3+ arrays, virtualization engine, and Fibre Channel
switches.
■ Serves as the service portal to all components in the Sun StorEdge 3900 or 6900
series subsystems.
Every Storage Service Processor is configured with the same hardware and software
components to ensure ease of replacement. All Storage Service Processors can
support the Sun StorEdge Remote Response option if the necessary hardware and
software are added.
Any single Storage Service Processor can become the collection point for other
geographically local Storage Service Processors, which is referred to as the master
Storage Service Processor.
Virtualization Engines
The virtualization engines are a pair of routers used when building a SAN
environment for the Sun StorEdge 6900 series subsystem. There is one pair of
virtualization engines in the Sun StorEdge 6910 system and there are two pairs of
virtualization engines in the Sun StorEdge 6960 system.
The virtualization engine provides the following functions:
■ LUN carving, or creating smaller virtual drives from physical LUNs
■ LUN masking, which restricts host HBA access to the virtual LUNs
The virtualization engine supports the multipathing functionality of the Sun
StorEdge T3+ array. That is, each unit in the Sun StorEdge 6910 system provides
physical access to all of the underlying Sun StorEdge T3+ arrays. Each virtualization
engine in the Sun StorEdge 6960 system provides physical access to half of the
underlying Sun StorEdge T3+ array partner groups. The virtualization engine pairs
offer two I/O paths to individual StorEdge T3+ arrays.
Virtual and physical device map synchronization is used by the virtualization
engine. If a virtualization engine fails, the second virtualization engine of the pair
maintains the I/O availability. All virtualization engine pairs use a single device
mapping of physical-to-virtual devices. A change in the physical or virtual mapping
results in a re-synchronization of the device mappings throughout the virtualization
engine pairs. To accomplish the synchronization, each virtualization engine pair is
connected to the other virtualization engine through a redundant pair of Fibre
Channel switch T-ports.

Page 33
Customer-Management Connection
The customer-management connection is a dedicated Ethernet connection provided
on each Storage Service Processor that connects to the designated master Sun
StorEdge 3900 and 6900 series storage subsystem. The master Storage Service
Processor is used to collect status data from each Sun StorEdge 3900 and 6900 series
machine using the LAN. The master Storage Service Processor then reports the
status data used by the Storage Service Processor that is equipped with Sun
StorEdge Remote Response software.
Customers can alternatively choose to do one or more of the following:
■ Use their management LAN to support network traffic other than that reported
by the Sun StorEdge Remote Response software.
■ Provide a private LAN to isolate the service traffic from customer traffic.
■ Supply a secure router to isolate the customer LAN from the Service Processor
LAN.
Storage Devices
The Sun StorEdge T3+ array, both the 36-Gbyte and 73-Gbyte versions, provides
backend data storage. In factory-configured basic configurations, the Sun StorEdge
T3+ arrays are configured with two LUNs per partner group or one LUN per
physical unit. Each LUN is a full-capacity RAID 5 (8 disks) volume with a segment
size of 16 Kbytes and is configured with a standby hot spare. Additional utilities are
provided on the Storage Service Processor that enable Sun-trained personnel to
reconfigure the Sun StorEdge T3+ array LUNs to meet workload performance
requirements.
The RAID levels supported by the Sun StorEdge T3+ array in the Sun StorEdge 3900
and 6900 series configurations are:
■ RAID 1 - Each data block in a RAID 1 volume is mirrored on two physical drives.
If one of the mirrored pair fails, the data from the other drive is used. Because the
data is mirrored in a RAID 1 configuration, the volume has only half the capacity
of the assigned drives. For example, if you create a 4-drive RAID 1 volume with
36-Gbyte drives, the resulting data capacity is4x36/2=72Gbytes.
■ RAID 5 - In a RAID 5 configuration, data is striped across the drives in the
volumes in segments, with parity information being striped across the drives, as
well. Because of this parity, if a single drive fails, data can be recovered from the
remaining drives. Two drive failures cause all data to be lost. A RAID 5 volume
has the data capacity of all the drives in the logical unit, less one. For example, a
5-drive RAID 5 volume with 73-Gbyte drives has a capacity of (5—1) x 73 = 292
Gbytes.
Chapter 2 Component Descriptions 15
Page 34
Ethernet Hub
The Sun StorEdge 3900 and 6900 series uses an Ethernet hub as the backbone for the
internal service network. The allocation of Ethernet ports is as follows:
■ 1 - Service Processor (per subsystem)
■ 1 - For each Fibre Channel switch
■ 1 - For each virtualization engine
■ 2 - For each Sun StorEdge T3+ array partner group
■ 1 - For the Ethernet hub that is installed in the second Sun StorEdge Expansion
Cabinet in the Sun StorEdge 3960 and 6960 systems
Fibre Channel Switches
The Sun StorEdge Network FC Switch-8 or Switch-16 switch provides cable
consolidation and increased connectivity. The Sun StorEdge Network FC Switch-8
and Switch-16 switches are used for the internal data interconnection infrastructure.
The switches are paired to provide redundancy. Two switches are used in each Sun
StorEdge 3900 series storage subsystem and four switches are used in each Sun
StorEdge 6900 series storage subsystem. Each switch is connected, through Ethernet,
to the service network for management and service from the Service Processor.
These switches can be monitored through the SANSurfer GUI, which is available on
the Storage Service Processor.
These switches are configured using the configuration utilities, which are discussed
in “Configuration Utilities” on page 18.
Sun StorEdge Expansion Cabinet
The Sun StorEdge 3900 and 6900 series are packaged in the Sun StorEdge Expansion
Cabinet, which is used for several other Sun products. This provides a consistent
look and feel. The customer accessible areas of a storage subsystem are clearly
labeled. Service-accessible areas of the storage subsystem will be clearly labeled as
such. All physical configurations will be completed by Sun-trained personnel. NonSun-service trained customers will have significantly limited access to the physical
layout of the storage subsystem.

Sun StorEdge T3+ Array syslog.conf
Configuration
To ensure that the Storage Service Processor is aware of the condition of each Sun
StorEdge T3+ array tray within these storage subsystems, the arrays are configured
to send their syslog.conf information back to the Storage Service Processor.
The information that is placed in each Sun StorEdge T3+ array is as follows:
# syslog.conf
# facility.level action
# messages to local syslog file
*.info /syslog
# messages to syslogd on another host
*.notice @192.168.0.1
# messages sent as SNMP traps
# messages sent as HTTP pushes

Configuration Features
This chapter describes the features associated with each of the supported Sun
StorEdge 3900 and 6900 series configurations.
This chapter is organized as follows:
■ “Standalone With No Remote Service” on page 39
■ “Multiple Units With No Remote Service” on page 40
■ “Remote Service to a Single Unit With No Host Connection” on page 41
■ “Remote Service to Multiple Units With No Host Connection” on page 42
Standalone With No Remote Service
A standalone Sun StorEdge 3900 or 6900 series storage subsystem can be configured
with no remote service.
In a standalone configuration with no remote service option, the Storage Service
Processor must be configured as a master service processor.
Supported features in this configuration are:
■ Storage Automated Diagnostic Environment
■ Management of components using the “Configuration Utilities” on page 45
■ Local/host access to monitoring, component management, and alerts
■ One customer IP addresses required to enable communication with the
customer’s internal LANs
39
Page 58
Multiple Units With No Remote Service
This configuration provides no remote services but does give the customer a
collection of Storage Service Processors.
It is recommended that the first Storage Service Processor be configured as the
master Storage Service Processor. If it can not be determined which is the first
Storage Service Processor, one should be selected by agreement of the customer and
Sun service engineer.

Command Line Interface
You might prefer to run the configuration utilities from the command line rather
than use the character user interface. The utilities for the maintenance of these
components in the Sun StorEdge 3900 and 6900 series storage subsystems are given
in the following subsections:
■ Storage Service Processor Global Commands
■ Storage Service Processor Sun StorEdge T3+ Array Commands
■ Storage Service Processor Switch Commands
■ Storage Service Processor Virtualization Engine Commands
Storage Service Processor Global Commands
The following are general utilities used to manage the Sun StorEdge 3900 and 6900
series storage subsystems.
The global Storage Service Processor commands are described briefly here. For a
complete description of a command and its function, refer to the individual man(1)
pages.
■ checkdefaultconfig(1M) - Checks all switches, virtualization engines, and
Sun StorEdge T3+ arrays in the Sun StorEdge 3900 and 6900 series subsystem
against factory-set configurations or the latest snapshot files.
■ getcabinet(1M) - Gets the cabinet configuration type for a Sun StorEdge 3900 or
6900 series configuration. The cabinet configuration type is based on the
components discovered in the cabinet. The types of cabinets returned are 3910,
3960, 6910, and 6960.
■ getipaddr(1M) - Gets and returns the IP address of a component.
■ listavailable(1M) - Provides a list of the available component names from the
/etc/hosts file for each Sun StorEdge 3900 or 6900 series storage subsystem.
The list varies, based on the system that is queried. Components that are offline or
busy are not listed.
■ removelocks(1M) - Removes all the configuration lock files. If the processes are
active, the locks will not be removed.
■ runsecfg(1M) - The menu-driven character user interface to the configuration
utility is accessed using the runsecfg command. Refer to “Menu-Driven
Interface” on page 46 for detailed information.
Chapter 5 Configuration Utilities 75
Page 94
■ setdefaultconfig(1M) - Sets all switches, virtualization engines, and Sun
StorEdge T3+ arrays in the Sun StorEdge 3900 or 6900 series storage subsystem to
the default configurations.
Caution – All data is destroyed when the setdefaultconfig command is
executed.
■ showerrors(1M) - Displays errors logged into the /var/adm/log/SEcfglog
log file.
■ showlogs(1M) - Displays either the complete log file or the number of lines
specified from the file, which is located in /var/adm/log/SEcfglog.
Storage Service Processor Sun StorEdge T3+
Array Commands
The commands in this subsection are used to manage the Sun StorEdge T3+ arrays
that are attached to the Sun StorEdge 3900 and 6900 series storage subsystems.
These utilities use a PASSWD environment variable as the Sun StorEdge T3+ array
password for telnet(1) session login. If this environment variable is not set, the
utility tries to log in without a password.
Note – If your passwords on the Sun StorEdge T3+ array are null, do not set this
variable. Also, only use this variable if you use the same password for each Sun
StorEdge T3+ array.
msp0# PASSWD=password
msp0# export PASSWD
If the environment variable is not set to the Sun StorEdge T3+ password, the
command fails.
The commands to configure the Sun StorEdge T3+ array are described briefly here.
For a complete description of a command and its function, refer to the individual
man(1) pages.
■ checkt3config(1M) - Checks the current Sun StorEdge T3+ array configuration
with the previously saved configuration. This checking is done by running the
Sun StorEdge T3+ array commands ver, vol list, vol stat, port list,
port listmap, sys list, and fru stat and comparing the output with the
previously stored configuration information. Any changes to the information are
reported.
76 Sun StorEdge 3900 and 6900 Series Reference Guide • February 2002
Page 95
■ modifyt3config(1M) - Configures Sun StorEdge T3+ arrays to user-specified
options and updates the configuration snapshot file.
■ modifyt3params(1M) - modifies the parameters of the Sun StorEdge T3+ arrays.
This command does not alter existing LUN configurations.
■ restoret3config(1M) - Restores Sun StorEdge T3+ array configurations with
static saved configurations from the snapshot file. This functionality might be
needed in case of loss of LUNs or the replacement of Sun StorEdge T3+ arrays.
The Sun StorEdge T3+ array configuration is restored to the previously saved
configuration.
By default, this utility compares the existing configuration with the saved one. If
they are identical, the saved configuration is not restored. If the configuration is
the same but the LUNs are in an unmounted state, the command will attempt to
mount the LUNs. If no checks with the saved configuration are needed, you must
specify the -f (force) option.
Caution – If a LUN is not mounted, restoret3config performs a mount on that
LUN. However, if any of the RAID configuration information is different, you might
lose data. To avoid this, run the checkt3config command to verify that the RAID
configuration has not changed before using the restoret3config command.
■ savet3config(1M) - Writes the latest information from the Sun StorEdge T3+
array into the snapshot file.
■ showt3(1M) - Reads and displays information from Sun StorEdge T3+ arrays.
showt3 uses some Sun StorEdge T3+ internal commands to obtain information.
The Sun StorEdge T3+ commands include vol list, vol stat, port list,
and port listmap.
Storage Service Processor Switch Commands
The following are utilities used to manage the Sun StorEdge network FC Switch-8
and Switch-16 switches that are used in Sun StorEdge 3900 and 6900 series storage
subsystems.
For a complete description of a command and its function, refer to the individual
man(1) pages.
■ checkswitch(1M) - Verifies that the current configuration on the switch matches
the predefined static configuration based on cabinet type and switch location.
■ setswitchflash(1M) - Downloads the flash code to the Sun StorEdge Network
FC Switch-8 or Switch-16 switch and resets it. The flash code is automatically
loaded from the appropriate file from the /usr/opt/SUNWsmgr/flash directory
unless an alternate file is specified with the -f option.

■ setswitchsl(1M) - Given a Sun StorEdge T3+ array name setswitchsl
configures all switch ports in the associated zone on both switches (down both
paths) to be SL mode. This command can also be used to return ports to the
default setting. This command is valid only on Sun StorEdge 3900 series
subsystems.
■ setupswitch(1M) - Configures a switch with predefined static configuration
information, based on the type of Sun StorEdge 3900 or 6900 series configuration.
■ showswitch(1M) - Displays configuration information about a switch. The
information includes the following:
■ IP address configuration
■ Version
■ Port status and type
■ Zones
Storage Service Processor Virtualization Engine
Commands
The Sun StorEdge 6900 series configuration utilities discussed in this subsection are
used to change the configuration of the virtualization engine. The configuration
utilities can be accessed by the menu-driven interface or individually.
After the StorEdge 6900 series systems are powered on and tested, the default
settings of the virtualization engine can be changed to meet the SAN environment in
which the system is installed.
Some of these utilities use a VEPASSWD environment variable as the virtualization
engine password for telnet(1) session login. The commands that use the
VEPASSWD variable include checkve(1M), resetsandb(1M), resetve(1M),
setupve(1M), and restorevemap(1M). If this environment variable is not set,
these utilities try to log in without a password.
Note – If your passwords on the virtualization engines are null, do not set this
variable. Also, only use this variable if you use the same password for each
virtualization engine.
msp0# VEPASSWD=password
msp0# export VEPASSWD
If the environment variable is not set to the virtualization engine password, the
command fails.

The commands to configure the virtualization engine are described briefly here. For
a complete description of a command and its function, refer to the individual man(1)
pages.
■ addtovezone(1M) - Adds a VLUN to the virtualization engine name, initiator,
and zone name specified.
■ checkslicd(1M) - Verifies that the slicd daemon is running and
communicating with the virtualization engine
■ checkve(1M) - Checks the parameter settings of the virtualization engine. The
parameter settings include the Ethernet settings, host side settings, device side
settings, and SV management programs.
■ checkvemap(1M) - Verifies that the live configuration of the virtualization engine
matches the saved configuration for that virtualization engine.
■ creatediskpools(1M) - Creates disk pools that map to physical LUNs on the
specified Sun StorEdge T3+ array. These disk pools can then be used to create
VLUNs. This command is typically called by the modifyt3config command
and not run directly by the user.
■ createvezone(1M) - Creates an HBA alias and zone of the same name for the
virtualization engine, initiator, and WWN specified.
■ createvlun(1M) - Creates VLUNs for the virtualization engine, disk pool, size,
and number specified.
■ delfromvezone(1M) - Removes a VLUN from the zone specified by the
virtualization engine, initiator, and zone name specified.
■ getdpspace(1M) - Returns the available space in the disk pool in Gbytes.
■ listve(1M) - Returns a list of the specified virtualization engine components
that are found by querying the system.
■ listvemap(1M) - Returns a list of the specified virtualization engine components
from the configuration map file. This command provides better performance than
the listve command, if the virtualization engine map file is up to date.
■ resetsandb(1M) - Clears the SAN databases on the virtualization engines and
resets both engines.
■ resetve(1M) - Resets the specified virtualization engine.
■ restorevemap(1M) - Restores the configuration from the saved map file to the
specified virtualization engine.
■ rmdiskpools(1M) - Removes disk pools and all VLUNs in the disk pool for the
specified Sun StorEdge T3+ array LUNs. This command is typically used when
you are performing a reconfiguration of the Sun StorEdge T3+ array. This
command is typically called by the modifyt3config command and not run
directly by the user.
■ rmvezone(1M) - Removes the zone for the virtualization engine, initiator, and
zone name specified.

CHAPTER
6
Fault Detection and Isolation
Overview
This chapter provides a brief overview of the functionality provided when using the
Storage Automated Diagnostic Environment software to perform fault detection and
isolation on the Sun StorEdge 3900 and 6900 series subsystems.
For detailed instructions on configuring and using the Storage Automated
Diagnostic Environment, refer to the Storage Automated Diagnostic Environment User’s
Guide.
This chapter is organized as follows:
■ “Monitoring” on page 81
■ “Fault Detection” on page 82
■ “Fault Isolation” on page 83
Monitoring
If the customer’s host is part of the configuration, monitoring of the individual
components is done by Storage Automated Diagnostic Environment through the
out-of-band paths connected directly to the host server.
Out-of-band refers to the connections and devices that are not in the data path. The
Storage Service Processor does not have access to the data that is stored on the Sun
StorEdge 3900 and 6900 series storage subsystems.

Page 100
Fault Detection
The Storage Automated Diagnostic Environment software running on the Storage
Service Processor collects and evaluates information about devices out-of-band to all
storage devices in the Sun StorEdge 3900 and 6900 series cabinet.
One way in which the Storage Service Processor can have access to the in-band
diagnostic information is to have a Storage Automated Diagnostic Environment
software running on the customer host that relays information to the Storage Service
Processor so that it can send the information to Sun service for monitoring purposes.
Local Monitoring
The Storage Automated Diagnostic Environment software has the ability to be
configured to send alerts and events to a mail(1) address or even a pager address.
Customers not interested in remote monitoring or not concerned about security may
choose to allow local monitoring of the Sun StorEdge 3900 and 6900 series products
only. In this case, the customer has two choices:
■ Allow the Storage Service Processor to be connected to their management LAN
and have access to one or more of their host servers.
■ Provide a standalone workstation to be connected to the Storage Service Processor
as a dedicated resource that will be staffed 24 hours a day, 7 days a week.
If you already have a license for Sun Remote Services NetConnect service (SRS), you
can choose that method to pass alerts and event status messages to Sun. In that
situation, the Storage Automated Diagnostic Environment software is configured as
a slave on the Storage Service Processor. The master system running Storage
Automated Diagnostic Environment software is located on the host where SRS is
running. The slave sends all of its alert and event traffic over the customer’s
management LAN to the SRS host server for shipment to Sun. The master system
running the Storage Automated Diagnostic Environment software is optionally
configured to send email or pager messages locally.
If the customer uses the management LAN connection without host SRS support, the
Storage Automated Diagnostic Environment software can be set up to send email or
pager message notification when an alert or event occurs. To use this service, the
customer must allow access to a host server containing email or pager message
service. The Storage Automated Diagnostic Environment software on the Storage
Service Processor is then configured as a slave and send all of its alert and event
traffic to the master system running the Storage Automated Diagnostic Environment
software on the customer’s host server. The master system is responsible for
forwarding the traffic through the specified medium.
