Service processor (SVP)
The Service Processor inside the controller performs these functions:
• Collects performance data on the system for diagnostic testing and analysis
• Provides your HP support representative with access to the system
• Hosts system management software
Your HP support representative uses the SVP to configure, maintain, and upgrade the
system software and hardware. The SVP is not a customer-accessible component.
To protect your security, the SVP does not have access to any user data stored on array
disks.
If you have extreme availability requirements, an optional second SVP is available.
HP StorageWorks Continuous Track XP
HP Continuous Track XP is a program in the system that detects and reports problems
even before they are noticed by operators and users.
HP Continuous Track XP “phones home” to the HP Storage Technology Center (STC),
providing:
• Periodic “well” checkups
This checkup records the health of the system on a day-to-day basis. Every 24 hours,
HP Continuous Track XP calls STC (your HP support representative sets the time of
the call). When a successful connection is made, status and configuration change
information is transferred from the system to STC.
• Incidental “sick” calls
When an error occurs, a service information message (SIM) is generated, stored
in the system for use by your HP support representative, and reported to STC. For
details, see Service information messages.
Note that the “phone home” capability can be turned off, if desired. HP Continuous Track
XP still monitors the system, but does not automatically notify HP if a problem occurs.
28
Hardware
Backup batteries
Internal batteries provide backup power for the cache memory, shared memory, and the
CHIPs. The backup batteries enable the system to continue normal operations for up to
20 milliseconds after the loss of AC power.
When AC power is off longer than 20 milliseconds, the system executes its backup
process. This process copies the contents of cache and shared memory to storage and
then supports cache and shared memory for up to 36 hours. Anytime the length of a
power outage exceeds the 36–hour battery backup time, contact HP for assistance
with recovery.
When power is restored, if the Auto-Power-On jumper is in the ENABLE position, the
system powers on automatically. If the jumper is in the DISABLE position, you must
turn the power switch on to power up the system. HP representatives will assist you in
determining which Auto-Power-On mode is best for your system configuration and will
configure the selected mode during system installation.
HP StorageWorks 200 Storage Virtualization System owner’s guide

System and storage management
HP Remote Web Console gives you browser-based control and management of the
system from a remote Windows client you supply. Additionally, to manage storage
systems, you must install the Command View Advanced Edition software on a Windows
Device Manager server you supply. Other HP StorageWorks software may also be
installed on this host, including the supplied External Storage and Tiered Storage
Manager applications that enable you to optimize use of your tiered storage systems.
See Chapter 4 for more information about supplied and optional HP software products.
To protect your security, Remote Web Console and HP Command View XP Advanced
Edition do not have access to user data stored on the storage systems.
You may use an existing host, such as your storage administrator’s PC, as the Device
Manager server provided that it meets system requirements for CV AE and the other
required and optional software you plan to deploy.
The CV AE Device Manager server (1) connects to the HP SVS200 system (3) using a
private Ethernet LAN connection (2), as shown in the following figure.

General safety guidelines
Carefully read these safety guidelines and follow them when working with the system.
• Fully understand and follow all hazard warnings in this guide and on warning
labels on the system. These hazard warnings help you to prevent or reduce the
risk of death, personal injury, or product damage. Hazard warnings include
alert headings consisting of an alert symbol and the word Caution or Warning:
CAUTION:
This indicates a hazardous situation which, if not avoided, will or can result in
serious product damage or loss of data.
WARNING!
This indicates a potentially hazardous situation which, if not avoided, can result in
death or serious injury.
• Replace any warning label that becomes dirty or starts peeling off.
• Keep in mind that the hazard warnings in this guide and on the HP SVS200
cannot cover every possible hazard because it is impossible to predict and
evaluate all potentially hazardous circumstances. Be alert and use common
sense. If you have any questions, contact your HP support representative.
• Follow the safety guidelines and procedures in all documentation for this and
related products.
CAUTION:
System maintenance must be done only by trained and qualified HP support
representatives. Only an HP support representative can power off the system, except
in an emergency.
CAUTION:
Do not perform any procedures not described in this guide. If you have any
questions or concerns, contact your HP support representative.
WARNING!
Do not touch areas marked HAZARDOUS, even with the power off. These areas
contain high-voltage power.
36
Operations
CAUTION:
If you detect any abnormal noise, smell, or smoke coming from the system,
immediately power off the system by following the emergency power off procedure
later in this chapter. For routine power off in non-emergency situations, contact
your HP support representative.
CAUTION:
Keep the front and rear doors closed at all times.
CAUTION:
Keep the tops and sides of the cabinets clear to allow air to flow properly.
CAUTION:

HP StorageWorks 200 Storage Virtualization System owner’s guide
37
Powering down the system
Two situations may arise when you need to power down the system:
• Emergency power off
• Planned power off
For instructions in each of these situations, see the following procedures.
Emergency power off
The system does not have an emergency power off switch. In an emergency when it is
crucial to power off the system immediately for safety reasons, remove power at the AC
branch circuit breakers in your facility that supply power to the system. Take care when
placing these breakers that they are clearly marked and easily accessible.
CAUTION:
Performing an emergency power off immediately shuts down the system, neglecting
the normal power off sequence. Jobs in process are aborted and their integrity
after recovery is not guaranteed. Use this power off method only in an emergency.
Afterwards, only a qualified HP support representative is allowed to restore power to
the system. Call your HP support representative immediately.
Emergency situations in which you should consider performing the emergency power
off procedure are:
• A physical location catastrophe such as a flood, hurricane, tornado, or
earthquake
• Any circumstance that presents the threat of injury or death to a person
• You detect any smoke, abnormal loud noise, or smell coming from the system.
38
Operations
Planned power off
Occasionally, you may need to plan a site power outage, such as during alterations
to the data center, inspections, or work by the electric company. If a scheduled power
outage will affect the system, contact your HP support representative to schedule a
planned power off.
CAUTION:
Only a trained HP support representative can shut down and power off the system. Do
not attempt to power down the system other than during an emergency.
HP StorageWorks 200 Storage Virtualization System owner’s guide
39
Recovering from an unplanned or emergency power
outage
Unplanned power outages occur when the primary building power is lost due to
electrical blackouts, thunderstorm activity, or similar occurrences, and input AC power
is not received by the system. The system will maintain its state and recover when
power is restored.
The system cache is powered by backup batteries that will maintain the system state for
up to 36 hours, depending on the selected battery operation mode.
For restart procedures after power is restored to the system, see the following text about
manual and automatic restart of the system. If the length of a power outage exceeds the
cache battery backup time, contact HP for assistance with recovery.
Manual restart after power is restored
CAUTION:
After power is restored to your site and before restoring power to the system, HP
recommends that you have an electrician verify the power to ensure that all phases are
restored and input power is stable. Before you power on the system, power on any
external disk array(s) first and make sure they are operating properly.
For assistance recovering from a power outage, contact your HP support representative.
To restart the system manually:
1. On the control panel, move the PS ENABLE switch to the ENABLE position.
2. Move the PS ON/OFF switch to the ON position.
The following LED power sequence occurs:
BS-ON turns amber.
PS-ON turns green.
MESSAGE LED may turn amber if the system is not configured to “phone home,”
signifying a SIM was generated because the system lost power unexpectedly.
READY LED turns green, signifying the system is ready.
40
Operations
CAUTION:
Power on can take several minutes and is not complete until the READY
LED turns green.
3. Move the PS ENABLE switch to “DISABLE” (opposite the ENABLE position).
HP StorageWorks 200 Storage Virtualization System owner’s guide
41
Automatic restart when power is restored
CAUTION:
HP recommends the use of automatic power on restart only if the power to the system
is subject to power conditioning equipment, such as a UPS, to ensure that the power
restored to the system is stable. If your site does not have a UPS, HP recommends
configuring the system for manual restart, meaning the Auto-Power-On jumper, which
is set during installation by an HP support representative, is in the DISABLE position.
After a power outage, follow the preceding manual restart procedure only after power
has been restored and verified to be stable. Before you power on the system, power on
any external disk arrays and make sure they are operating properly.
Automatic restart is enabled by your HP representative during installation. With
automatic restart enabled, the system automatically restarts and returns to service when
power is restored after a power outage.
During the automatic restart, the following LED power sequence occurs:
BS-ON turns amber.
PS-ON turns green.
MESSAGE LED may turn amber if the system is not configured to “phone home,”
signifying a SIM was generated because the system lost power unexpectedly.
READY LED turns green, signifying the system is ready.
CAUTION:
Powering on the system can take several minutes. Power on is complete only when the
READY LED turns green.

Software
HP LUN Configuration and Security Manager
HP LUN Configuration and Security Manager provides additional LUN configuration
and security options. You can add and delete paths, create custom-sized volumes, and
configure foolproof LUN security that provides controlled, secure access to data stored
on the disk arrays—preventing unauthorized servers from accessing your data. It also
configures the arrays to meet changing storage requirements and enables users to share
a single Fibre Channel array among multiple servers.
HP LUN Configuration and Security Manager allows you to:
•
•
•
•
Create, define, and configure LUNs on the disk arrays
Consolidate LUNs (combine up to 36 LUNs)
Create small size LUNs to accommodate data locked into cache
Establish security at the LUN level so that you can enable multiple server
connectivity to the disk arrays
• Hide LUNs assigned to one server from other servers during IOSCAN operations
• Configure LUSE and create custom volume sizes
HP Cache LUN
Cache LUN lets you reserve areas of memory cache to store frequently accessed
information. It improves file access times and enables faster data transfers. Assigning
information to on-board cache speeds up access to your data because cache-resident
data is available at host data transfer speeds for both read and write operations.
Cache LUN redirects I/O requests from the disk drives to data locked in the SVS200
cache. It’s transparent, simple to implement, and it delivers immediate performance
gains. Cache memory for Cache LUN can be set as low as one logical block or 512
MB. As your needs grow, you can increase cache volumes in increments of one logical
block to a maximum of 1,024 cached volumes.

HP Tiered Storage Manager
HP Tiered Storage Manager is a plug-in for the HP Command View XP Advanced
Edition Software. The plug-in migrates data to tiered storage systems according to
quality of service requirements, matching the defined quality requirements of the data to
the appropriate storage tier. It is a completely non-disruptive application that you can
schedule or start immediately, once you have designed a migration plan. The software
relieves you of data migration concerns, allowing you to define the migration criteria
once and then let the software handle migration automatically. Management via the HP
Command View XP Advanced Edition Software GUI ensures user friendly operation of
the migration setup and process. Attributes include such data as volume type, capacity,
emulation type, RAID level and disk type. Groups are created which place similar
demands on the storage resources.
Features and benefits:
• Matches quality of service requirements to data storage attributes
• Allows you to create migration groups to handle volumes with similar storage
requirements together
• Easy to use with convenient screens to save you time setting up storage groups
and tiers
• Runs on demand or according to automated schedules
48
Software
HP StorageWorks Business Copy and HP Snapshot
XP
The optional HP Business Copy (BC) software allows you to make up to nine ongoing
copies of data for nonproduction activities such as backup, batching, and system
testing. HP Business Copy supports HP Snapshot. HP Snapshot is optional software that
creates multiple, point-in-time, online, local copies without impacting primary production
operation. HP Snapshot may require additional shared memory.
HP StorageWorks Continuous Access Synchronous
and HP Continuous Access Asynchronous
The optional HP Continuous Access Synchronous software allows you to make ongoing
synchronous copies of array data to a remote array located many miles away from the
source array.
The optional HP Continuous Access Asynchronous software is similar to HP Continuous
Access Synchronous, but it operates in asynchronous mode. Transactions to be written
to the secondary array are kept in cache memory on the local array in a “side-file.”
This potentially increases performance in remote copying. Copy operations are
sequence-stamped to ensure they are executed and sorted correctly at the remote disk
array.
HP StorageWorks XP Disk/Cache Partition
HP Disk/Cache Partition software can help Enterprise customers subdivide a large XP
disk array into smaller storage segments for accomplishing corporate storage related
initiatives such as consolidation, tiered storage, chargeback, and application usage
tracking. Each domain or partition is separately configured and managed. Each
partition has its own assigned host ports, disk groups, and cache. This software can
reduce storage costs by dividing the disk array into smaller segments suitable for
departmental usage, while retaining superb performance and high availability.

Service information messages
The system generates service information messages (SIMs) to identify normal operations,
service requirements, and failures. SIMs are generated by the SVP and the system
microprocessors. Your HP support representative uses the SIMs to monitor and
troubleshoot the system. You can view SIMs using the system’s management software.
HP StorageWorks 200 Storage Virtualization System owner’s guide

Failure detection and reporting process
If a failure occurs in the system, the failure is detected and reported to the system log, the
SIM log, and the HP STC, as shown in the following figure and table.
Item
52
Description
1
A failure is detected in the system.
2
The failure is reported to the system.
3
The system stores the failure information in the system log.
4
The generated SIMs are stored on the system for use by HP support
representatives, and logged on the Device Manager server as remote SIMs
(R-SIMs).If the system is not set up to “phone home,” when a SIM is generated,
the amber message LED on the system control panel turns on. Call HP to
determine the reason for the message.
5
If the system is set up to “phone home,” Continuous Track XP reports the SIMs to
STC through a dedicated dialup connection.SIMs are classified according to
severity: service, moderate, serious, or acute. Service and moderate levels do
not require immediate attention and are addressed during routine maintenance.
These failures are often corrected before the failure becomes apparent. Serious
and acute levels are reported immediately to STC to ensure that the problem is
addressed as soon as possible.

Glossary
ACP
Array control processor. On some XP models, such as the
XP12000, the ACP handles the passing of data between the
cache and the physical drives. On other XP models, such as
the XP10000 and SVS200, this function is handled by the disk
adapter on the MIX board.
AL
Arbitrated loop.
AL-PA
Arbitrated loop physical address.
allocation
The ratio of allocated storage capacity versus total capacity as
a percentage. “Allocated storage” refers to those LDEVs that
have paths assigned to them. The allocated storage capacity is
the sum of the storage of these LDEVs. Total capacity refers to
the sum of the capacity of all LDEVs on a disk array.
array group
A group of 4 or 8 physical hard disk drives (HDDs) installed in
an XP disk array and assigned a common RAID level. RAID1
array groups consist of 4 (2D+2D) or 8 HDDs (4D+4D). RAID5
array groups include a parity disk but also consist of 4 (3D+1P)
or 8 HDDs (7D+1P). All RAID6 array groups are made up of
8 HDDs (6D+2P).
ASE

BC
The HP StorageWorks Business Copy XP software program,
which enables you to maintain up to nine internal copies of
logical volumes on a disk array.
C-Track
The HP StorageWorks Continuous Track XP software program,
which detects internal hardware component problems on a disk
array and automatically reports them to the HP STC.
Continuous Access
The HP StorageWorks Continuous Access XP program, which
enables you to replicate data stored on a local disk array to a
remote disk array.
cache
Very high speed memory that is used to speed I/O transaction
time. All reads and writes to a disk array are sent to the cache.
The data is buffered there until the transfer to/from physical
disks (with slower data throughput) is complete.
HP StorageWorks 200 Storage Virtualization System owner’s guide
65
The benefit of cache memory is that it speeds I/O throughput
to the application. The larger the cache size, the greater
the amount of data buffering that can occur and the greater
throughput to the applications.
The SVS200 supports a range of cache memory. In the event
of power loss, battery power holds up the contents of cache
for up to 36 hours.

control unit
To organize the storage space attached to the DKC, you can
group similarly configured logical devices (LDEVs) with unique
control unit images (CUs). CUs are numbered sequentially. The
disk array supports a certain number of CUs, depending on
the disk array model. Each CU can manage multiple LDEVs.
Therefore, to uniquely identify a particular LDEV requires both
the CU number and the LDEV number.
