Fault management and diagnostics
WEBES must be i nstalled to ensure proper customer alerts for their EVA products.
WEBES can be used as part of the HP ISEE remote service offering. Or, for those customers who
do not wish to have remote suppor t, it can be configuredtosendalocalnotification (e-mail) to a
customer-identified account only. The e-mail option is also available to the customer when ISEE is used.
WEBES is a powerful service tool that provides real-time diagnosis of hardware events ranging from
single errors (or faults) to multiple event correlation and complex analysis. It is designed to send a
notification only when an event or series of events has occurred that requires a service action.

Storage system components
The Enterprise Virtual Array comprises three main components:
• Hardware—the physical components, such as disk d rives, enclosures, controllers, and Fibre
Channel switches. These pieces are installed in a rack and connected to the SAN.
• HP StorageWorks Controller Soft ware—manages operation of the storage system hardware and
provides the communication link to HP Command View EVA.
• HP Command View EVA—management software that communicates with the controllers.
Together, HP Command View EVA and the controllers control and monitor Enterprise Virtual
Array storage systems.
These components work together to create an entire storage system solution. Management is
accomplished by accessing HP Command View EVA through your browser.

Operating tips and information
Reserving adequate free space
To ensure efficient storage system operation, a certain amount of unallocated capacity, or free space,
should be reserved in each disk group. The recommended amount of free space is influenced by your
system configuration. For guidance on how much free space to reserve, refer to the HP StorageWorks
Enterprise Virtual Array configuration best practices white paper. See Best practices.
Using FATA disk drives
FATA drives are designed for lower duty cycle applications such as near on-line data replication for
back-up. These drives should not be used as a replacement for EVA’s high performance, standard
duty cycle, Fibre Channel drives. Doing so could shorten the life of the drive. Download the following

Saving storage system configuration data
As part of an overall data protection strategy, storage system configuration data should saved during
initial installation, and whenever major configuration changes are made to the storage system. This
includes adding or removing disk drives, creating or deleting disk groups, and adding or deleting virtual
disks. The saved configuration data can save substantial time should it ever become necessary to
re-initialize the storage system. The configuration data is saved to a series of files stored in a location
other than on the storage system.
This procedure can be performed from the SAN Management Appliance (SMA) or management server
where the Command View EVA application is installed, or any host that can run the Storage System
Scripting Utilit y (SSSU) to communicate with the Command View EVA application server.
NOTE:
SSSU version 4 is required for HP Command View EVA 4.0 and later. For more information on using
SSSU, refer to the

2. Enter SELECT MANAGER and select the management server.
3. Enter SHOW SYSTEM to determine which storage systems are managed by this instance of HP
Command View EVA.
4. Enter SELECT SYSTEM to select the appropriate storage system from which to collect configuration
data.
36
Enterprise Virtual Array operation
5. Enter CAPTURE CONFIGURATION, specifying the full path and fi lename of the output files for
the configu ration data.
The configuration data is stored in a series of from one to five files, which are SSSU scripts. The
file names begin with the name you choose, with the restore step appended. For example,
if you specify a file name of LargeEVA.txt,theresultantconfiguration files would be
LargeEVA_Step1A.txt, LargeEVA_Step1B,etc.
The contents of the configuration files can be viewed with a text editor.
NOTE:
If the storage system contains disk drives of different capacities, the SSSU procedures used do not
guarantee that disk drives of the same capacity will be exclusively added to the same disk group. If you
need to restore an array configuration that contains disks of different sizes and types, you must manually
recreate these disk groups. The controller software and the utility’s CAPTURE CONFIGURATION
command are not designed to automatically restore this type of configuration. For more information,
refer to the
HP StorageWorks Storage System Scripting Utility reference
.
The following examples illustrate how to save and restore the storage system configuration data using
SSSU on a Windows host.
Example 1. Saving configuration data using SSSU on a Windows Host
Run SSSU from a DOS Command Window on the SMA, a Windows Workstation or a Windows Server
that can access the SMA by TCP/IP or the management host running Command View.
1. Click Run on the Window Start menu.
2. Enter cmd in the Open field to open the DOS Command Window.
3. Change to the directory (CD) in which you have installed SSSU. For example, C:> cd \SSSUDir
4. Enter SSSU to run the application.
5. Enter SELECT MANAGER <SMAname or ip_addr> user=<username> pass=<userpass-
word>.
6. Enter SHOW SYSTEM to display the EVA storage systems managed by the SMA or Windows Host.
7. Enter SELECT SYSTEM <EVA_Name>,whereEVA_name isthenameofthestoragesystem.
The storage system name is case sensitive. If there are spaces between the letters in the name, quotes
must enclose the name. For example, SELECT SYSTEM “Large EVA”.

Adding disk driv
As your storage requirements grow, you may be adding disk drives to your storage system. Adding new
disk drives is the easiest way to increase the storage capacity of the storage system. Disk drives can be
added online without impacting storage system operation.
es to the storage system
Guidelines for adding disk drives
When adding new disk drives to the storage system, you should ensure that the disk drives are installed
in the correct positions to maintain availability. The disk drives should be distributed across the disk
enclosures to protect against the failure of a sing l e disk enclosure.
Use the following guidelines when adding disk drives to your storage system:
• Install high performance and FATA disk drives in separate groups. These different drive types must
be in separate d isk groups. You may also want to consider separating different drive capacities
and spindle speeds into different groups.
• Thediskdrivesshouldbedistributedevenlyacrossthediskenclosures.Thenumberofdisksof
a given type in each enclosure should not differ by more than one. For example, no enclosure
should have two disks until all the other enclosures have at least one.
• Disk drives should be installed in vertical columns within the disk enclosures. Add drives vertically
in multiples of eight, completely filling columns if possible. Disk groups are more robust if filled
with the same number of disk drives in each enclosure. See Figure 6 for an example.
NOTE:
When adding multiple disk drives, add a disk and wait for its activity indicator ( 1) to stop flashing
(up to 90 seconds) before installing the next disk (see Figure 5). Thisproceduremustbefollowedto
avoidunexpectedEVAsystembehavior.
Figure 5 Disk drive activity in dica tor
Creating disk groups
Thenewdisksyouaddwilltypicallybeusedtocreatenewdiskgroups. Althoughyoucannotselect
which disks will be part of a d isk group, you can control this by building the disk groups sequentially.
Add the disk drives required for the first disk group, and then create a disk group using these disk drives.
Now add the disk drives for the second disk group, and then create that disk group. This process gives
you control over which disk drives are included in ea ch disk group. Figure 6 shows the sequential
building of vertical disk groups.
38
Enterprise Virtual Array operation
NOTE:
Standard and FATA disk drives must be in separate disk groups. Disk drives of different capacities and
spindle speeds can be included in the same disk group, but you may want to consider separating
them into separate disk groups.

Blowers
The power supply–mounted blowers cool the enclosure by circulating air through the enclosure. The
blowers, under the control of the EMU or the associated power supply, can operate a t multiple speeds.
This ensures that when the enclosure temperature changes the blowers can automatically adjust the
air flow.
If a blower is operating too slowly or has stopped (a “blower failure”), internal circuitry automatically
operates the remaining blower at a higher speed. Simultaneously, the error condition is reported in
several ways, including the power supply indicator, the audible alarm, the enclosure fault indicators,
and the EMU alphanumeric display.
Should both blowers fail, the power supplies automatically shut down.
NOTE:
The blowers are field-replaceable units and can be replaced, individually, while the system is running.
The blowers are also interchangeable. The failure of a power supply +12.5 VDC circuit disables the
associated blower.
The status indicator on the blower displays the status of both the power supply and the blower. See

• Using the Enclosure Services Processor (ESP) to control the Enclosure Services Interface (ESI) and
communicate with the controllers.
• Assigning the Enclosure Number (En), based upon the cabinet address bus feature.
• Displaying the bay 1loopID.
• Monitoring enclosure operation.
• Detecting, reporting, recording, and displaying conditions.
• Displaying EMU, enclosure, and element status.
• Implementing automatic corrective actions for some conditions.
• Providing enclosure status data to the controllers.
• Reporting the WWN and the logical address of all disk drives.

the data displayed or entered.
Alphanumeric display description
The top-level, two-character alphanumeric display (En, Li, rG, Au, and Er), is the display group. The
function of the other displays is display-group dependent. The default display is the enclosure number, a
decimal number in the range 00 through 14. The push buttons allow you to select the alphanumeric
display or to enter data.
• The bottom push button sequentially moves between groups and selects a display group .
See EMU display groups for a description of these display groups.
• The top push button moves between the levels within a display group (see 2, Figure 17).

NOTE:
Any time you press and release the bottom push button the display will change to En, Li, rG, Au, or Er.
A flashing alphanumeric display indicates that you can edit an address, state, or view a condition report.
EMU push button status indicators
The push button status indicators display error conditions and the state of the audible alarm.
• When an error co n dition exists, the top push button status indicator is On.
• For a single error condition, the status indicator is On until the error condition is viewed.
• For multiple errors, the status indicator is On until the last error condition is viewed.
• The bottom push button indicator is On only when the alarm is muted or disabled.
Audible alarm operations
Whenever an error condition exists, the audible alarm automatically sounds until all errors are corrected.
You have the option of either muting o r disabling the alarm.
• Disabling the audible alarm prevents it from sounding for any error condition.
• Muting the alarm silences it for the existing condition, but any new condition causes the alarm
to sound.
Audible alarm patterns
The audible alarm sound pattern differs depending on the type of error condition. See Table 17 for the
duration and the approximate relationship of these alarms. The most severe, active error condition
controls the alarm pattern.

Enclosure numb
This section provides a description of the purpose, function, and operation of the EMU enclosure number
(En) feature.
En description
In a single rack con fig uration, the En is a decimal numb er in the range 00 through 1 4, which is
automatically assigned by the enclosure address bus.
NOTE:
Your storage system may use an enclosure address bus higher than 14 if your configuration includes an
optional expansion cabinet. The enclosure address bus connection determines the En. For a s ingle rack,
the di splay is a decimal number in the range 01 through 14. For a multiple (two) rack configuration, the
display is decimal number in the range 01 through 24.
By default, the two-character alphanumeric display shows this number. Pressing the bottom push button
changes the display to En,theEndisplaymode.
When the display is En, pressing and releasing the top push button displays the enclosure number.
A display of 00 indicates that the enclosure is not connected to the enclosure address bus. When this
condition exists, there is no EMU-to-EMU communication over the enclosure address bus.
A display of 01 through 14 indicates that the enclosure is connected to the enclosure address bus and
can exchange information with other enclosures on the enclosure address bus. The decimal number
indicates the physical position of the enclosure in relation to the bottom of the rack.
er feature
• 01 is the address of the enclosure connected to the lower connector in the first (lower) enclosure
ID expansion cable.
• 14 is the address of the enclosure closest to end of the bus, the upper c onnector in the last
(upper) ID expansion cable.
Unless there is an error condition, the display automatically returns to the enclosure number (01 through
14)oneminuteafterapushbuttonwaslastpressed.
Enclosure address bus
The enclosure address bus provides a means for managing and reporting environmental conditions within
the rack. It is composed of enclosure ID expansion cables that interconnect the drive enclosures an d
controller enclosures. Two drive enclosures connect to each enclosure ID expansion cable.
The drive enclosure numbers are always assigned by the enclosure address bus. Connecting the EMU
CAB connector to an enclosure address bus enclosure ID expansion cable automatically establishes an
enclosure number of 01 through 14. Any drive enclosure not connected to the enclosure address bus
has the enclosure number 0 0.
NOTE:
The enclosure number is automatically assigned. You cannot manually assign an enclosure number.
The enclosures are numbered as shown in Figure 18.

Enclosure address bus connections
Connecting the enclosures to the enclosure ID expansion cables establishes the enclosure address bus.

Error Condition Reporting
The EMU constantly monitors enclosure operation and notifies you of conditions that c ould affect
operation. When an error condition is detected, the following action is taken:
• The EMU alphanumeric display is changed to Er. A condition report has precedence over all
other displays.
• The audible alarm sounds (if it is not disabled).
• The error is stored in the error queue.
• The error is passed to the controllers for processing and display by Command View EVA.
60
Enterprise Virtual Array hardware components
NOTE:
An error always generates a condition report. Not all condition reports are generated by errors.
Error condition categories
Each error condition is assigned to a category based on its impact on disk enclosure operation. The
following four error categories are used:
• Unrecoverable—themostsevereerrorcondition,itoccurswhenoneormoreenclosure
components have failed and have disabled some enclosure functions. The enclosure may be
incapable of correcting, or bypassing the failure, and requires repairs to correct the error.
NOTE:
To maintain data integrity, corrective action should be implemented immediately for an
UNRECOVERABLE condition.
• Critical—occurs when one or more enclosure components have failed or are operating outside
of their specifications. The failures impact the normal operation of some components in the
enclosure. Other components within the enclosure may be able to continue normal operations.
Prompt corrective action should be taken to prevent system degradation.
• Noncritical—occurs when one or more components inside the enclosure have failed or are
operating outside of their specifications. The failure of these components does not impact
continued normal operation of the enclosure. All components in the enclosure continue to
operate according to their specifications. The ability of the components to operate correctly
may be reduced should other errors occur. Prompt corrective action should be taken to prevent
system degradation.
• Information—the least severe condition indicates a condition exists that does not reduce the
capability of a component. However, the condition can become an error and require corrective
action. An INFORMATION condition provides an early warning, which enables you to prepare
to implement corrective action before a component fails. Correction of the reported problem
may be delayed.
Theerrorconditionsareprioritizedbyseverity—frommostseveretoleast. Themostseverecondition
takes precedence and is reported first when multiple errors are detected. The reporting characteristics

The EMU maintains an internal error queue for storing error conditions. Each error condition remains in
the error queue until the problem is corrected, or for at least 15 seconds after the error is reported. This
es that when there are multiple errors or a recurring error, each can be displayed. Each entry in the
ensur
queue can be displayed using a combination of the top and bottom buttons. Each error entry in the
error
queue contains the element type, the element number, and the error code.
Enterprise Virtual Array 3000/5000 user guide
61
Correcting the error removes the associated condition from the error queue. Replacing the EMU will
also clear the error conditions. The order in which the EMU displays the error queue information is
based on two factors:
• The severity of the error
• Thetimetheerroroccurred
The most severe error in the queue always has precedence, regardless of how long less severe errors
have been in the queue. This ensures that the most severe errors are displayed immediately.
NOTE:
When viewing an error, the occurrence of a more severe error takes precedence and the display changes
to the most severe error.
The earliest reported condition within an error type has precedence over errors reported later. For
example, if errors at all levels have occurred, the EMU displays them in the following order:
1. UNRECOVERABLE errors in the sequence they occurred.
2. CRITICAL errors in the sequence they occurred.
3. NONCRITICAL errors in the sequence they occurred.
4. INFORMATION conditions in the sequence they occurred.
Error condition report format
Each EMU detected condition generates a condition report containing three pieces of information.
• Element type The first two-digit hexadecimal display defines the element type reporting the
problem. The format for this display is e.t. with a period after each character. Valid element
types are 0.1. through F.F.
• Element number The second display is a two-digit decimal number that defines the specificelement
reporting the problem. The format for this display is en. with a period after the second character.
• Error code The third display is a two-digit decimal number that defines the specificerrorcode.
The format for this display is ec without any periods.
For detailed information about each condition report, including recommended corrective actions.
Navigating the error condition display
When an error condition occurs, the alphanumeric display changes to Er and the error menu is active.
Thebuttonsareusedtodisplaytheerrorconditionvalues.
Perform the following procedure to display error conditions. Figure 20 illustrates the sequ ence for
displaying error conditions.
1. With Er in the display, press and hold the top push button until the first element type is displayed.
Themostsevereerrorinthequeuewillbedisplayed.
2. Release the top push button when the element type is displayed. The element type has both decimal
points lit.
3. Press and release the top push button to display the element number. This display has only the
right decimal point lit.
4. Press and release the top push button again to display the error code. This display has no d ecimal
points lit. Repeated press/release operations will cycle through these three values.
5. Press and hold the top push button from any of the three display states to move to the element
type for the next error condition in the queue.
6. Use the top push button to display the values for the error condition.
7. When all error conditions have been displayed, press and release the b ottom push button to return
to the Er display.

Analyzi
ng condition reports
Analyzing each error condition report involves three steps:
1. Identifying the element.
2. Determining the major problem.
3. Defining additional problem information.
Reporting group feature
Another function of the enclosure address bus is to provide communications within a reporting group.
A Reporting Group (rG) is an HSV controller pair and the associated drive enclosures. The controller
pair automatically assigns a unique (decimal) four-digit Reporting Group Number (RGN) to each EMU
on a Fibre Channel drive enclosure.
Each of the drive enclosures on a loop pair are in one reporting group:
• All of the drive enclosures on loop pair 1, both loop 1A and loop 1B, share a unique reporting
group number.
• All of the d rive enclosures on loop pair 2, both loop 2A and loop 2B, share a unique reporting
group number.
Each EMU collects environmental information from the associated enclosure and broadcasts the
information to reporting g roup members using the enclosure address bus. Information from enclosures
in other reporting groups is ignored.
Enterprise Virtual Array 3000/5000 user guide
63
Reporting group
The reporting group number (RGN) range is 0000 through 4099, decimal.
• 0000 is reserved for enclosures that are not part of any reporting group.
• 0001 through 00
• 0016 through 4095 are valid RGNs.
• 4096 through 4099 are invalid RGNs.

All data cables and power cables attach to the rear of the controller. Adjacent to each data connector is
a two-colored link status indicator. Table 23 identifies the status conditions presented by these indicators.
NOTE:
These indicators do not indicate whether there is communication on the link, only whether the link
can transmit and receive data.
The data connections are the interfaces to the disk drive enclosures or loop switches (depending on your
configuration), the other controller, and the fabric. Fiber optic cables link the controllers to the fabric,
and, if an expansion cabinet is part of the configuration, link the expansion cabinet drive enclosures to
the loop switches in the main cabinet. Copper cables are used between the controllers (mirror port) and
between the controllers and the drive enclosures or loop switches.
Racks
All storage system components are mounted in a rack. Each configuration includes t wo controller
enclosures (the controller pair), drive enclosures, FC loop switches (if required), and an expansion
bulkhead. Each controller pair and all the associated drive enclosures form a single storage system.
Rack configurations
Each system configuration depends on the number of disk enclosures included in the storage system. For
more information about racks and configurations, including expansion and interconnection, refer to the
HP StorageWorks Enterprise Virtual Array hardware confi guration guide.
Power distribution
AC power is distributed to the rack through a dual Power Distribution Unit (PDU) assembly mounted at the
bottom rear of the rack. The characteristics of the fully-redundant rack power configuration are as follows:
• Each PDU is connected to a separate circuit breaker-protected, 30–A AC site power source
(220–240 VAC ±10%, 50 or 60–Hz, ±5%). Figure 24 illustrates the compatible 60–Hz and
50–Hz wall receptacles.

Figure 24 60–Hz and 50–Hz wall receptacles
• The standard pow er configuration for any Enterprise Virtual Array rack is the fully redundant
configuration. Implementing this configuration requires:
• Two separate circuit breaker-protected, 30–A s ite power sources with a compatible wall
receptacle (see Figure 24).
• O ne dual PDU assembly. Each PDU connects to a different wall receptacle.
• Six Power Distribution Modules (PDM) per rack. Three PDMs mount vertically on each side
of the rack. Each set of PDMs connects to a different PDU.
• The drive enclosure power supplies on the left (PS 1 ) connect to the PDMs on the left with a
gray, 66 cm (26 in) power cord.
• The drive enclosure power supplies on the right (PS 2) connect to the PDMs on the right with a
black, 66 cm (26 in) power cord.
• The upper controller connects to a PDM on the left with a gray, 152 cm (60 in) power cord.
• The lower controller connects to a PDM on the right with a black, 66 cm (26 in) power cord.
PDUs
NOTE:
Drive enclosures, when purchased separately, include one 50 cm black cable and one 50 cm gray cable.
The configuration provides complete power redundancy and eliminates all sing le points of failure for
both the AC and DC power distribution.
Each Enterprise Virtual Array rack has either a 50– or 60–Hz, dual PDU mounted at the bottom rear
of the rack. The 228481–002/228481–003 PDU placement is back-to-back, plugs facing down, with
switches on top.
• The standard 50–Hz PDU cable has an IEC 309, 3–wire, 30–A, 50–Hz connector.
• The standard 60–Hz PDU cable has a NEMA L6–30P, 3–wire, 30–A, 60–Hz connector.
If these connectors a re not compatible with the site power distribution, you must replace the PDU power
cord cable connector.
Each of the two PDU power cables has an AC power source specific connector. The circuit
breaker-controlled PDU outputs are routed to a group of four AC receptacles (see Figure 25). The
voltages are then routed to PDMs, sometimes referred to as AC power strips, mounted on the two vertical
rails in the r ear of the rack.

Verifying component failure
• Make sure you confer with HP technical support to verify that the hardware component has failed
and that you are authorized to replace it yourself.
• Additional hardware failures can complicate component replacement. Check HP StorageWorks
Command View EVA and/or the WEBES System Event Analyzer as follows to detect any
additional hardware p roblems:
• W hen you have confirmed that a component replacement is required, you may want to clear
the Real Time Monitoring view. This makes it easier to identify additional hardware problems
that may occur while waiting for the replacement part.
• Before installing the replacement part, check the Real Time Monitoring view for any new
hardware problems. If additional hardware problems have occurred, contact HP support
before replacing the component.
• Refer to the System Event Analyzer online help for additional information.

Procuring the spare p art
•Table27lists the parts that qualify for CSR, including assembly and spare numbers. Parts have
a nine–character spare c omponent number on their label (Figure 30). The first six characters
(123479) identify the element; the last three characters (002) define the revision level. The
replacement component revision level must be the same as, or greater than, the number on the
element being replaced. The higher the revision level, the later the revision.

Regulatory notices
Federal Communications Commission (FCC) notice
Part 15 of the Federal Communications Commission (FCC) Rules and Regulations has established Radio
Frequency (RF) emission limits to provide an interference-free radio frequency spectrum. Many electronic
devices, including computers, generate RF energy incidental to their intended function and are, therefore,
covered by these rules. These rules place computers and related peripheral devices into two classes, A
and B, depending upon their intended installation. Class A devices are those that may reasonably be
expected to be installed in a business or commercial environment. Class B devices are those that may
reasonably be expected to be installed in a residential environment (for example, personal computers).
The FCC requires devices in both classes to bear a label indicating the interference potential of the device
as well as additional operating instructions for the user.
The rating label on the device shows the classification (A or B) of the equipment. Class B devices have an
FCC logo or FCC ID on the label. Class A devices do not have an FCC logo or FCC ID on the label.
After the class of the device is determined, refer to the corresponding statement in the following sections.

can be determined by turning the equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipm ent into an outlet on a circuit that is different from that to which the receiver is
connected.
• Consult the dealer or an experienced radio or television technician for help.
Declaration of conformity for products marked with the FCC logo, United States only
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:
(1) this device may not cause harmful interference, and (2) this device must accept any interference
received, including interference that may cause undesired operation.
