About this guide
1 Getting started
This chapter provides information about required kits and reference documentation. Check that you
have met the requirements and have all the required materials before you begin the upgrade procedures
described in this guide.
HP Command View EVA can be implemented in two ways:
• Server-based management — HP Command View EVA is installed on a management server connected to the EVA, providing management of multiple HP EVA storage systems. All components
of the software suite (HP Command View EVA, HP Command View EVAPerf, HP Storage System
Scripting Utility, SMI-S EVA) are installed. Server-based management applies to all EVA models.
• Array-based management — Beginning with HP Command View EVA 8.1, the EVA4400 is
shipped with HP Command View EVA pre-installed on the management module within the controller
enclosure. Only one component of the software suite (HP Command View EVA) is installed. Arraybased management applies only to the EVA4400.
Overview
An upgrade to XCS 09521000 must be performed offline, regardless of your current version.
During an offline upgrade (shutdown upgrade), all host I/O to the storage system must be stopped.
All applications and hosts are shut down before the controller upgrade is done, and restarted when
the upgrade is complete.
An offline upgrade requires scheduling time with application managers, and having staff on hand to
shut down and restart applications and hosts. While actual upgrade time may be short, offline upgrades
can require several hours to complete from the start of the first application shutdown until all hosts
and applications have returned to service.
Upgrade paths
IMPORTANT:
Check HP StorageWorks Enterprise Virtual Array release notes (XCS 09521000) for the latest
information about supported upgrade paths.
See Table 3.1, Upgrade support for controller software versions, in the HP StorageWorks Enterprise
Virtual Array compatibility reference for more information about supported upgrade paths. For
downgrade information, see Table 3.2, Downgrade support for controller software versions, in the
HP StorageWorks Enterprise Virtual Array compatibility reference. See Table 2 for document location.

occurring. If any unusual icons are visible, check with HP before doing the upgrade.
NOTE:
If you must replace any components, see the user guide for your array model for information about
replacement. See Table 2 on page 12 for links to these guides.
Checking and upgrading your SAN infrastructure
Estimated time to complete: Varies depending on the number of components that may require upgrade.
When to perform: Any time prior to the upgrade
It is important to ensure that your SAN environment meets the configuration requirements of the XCS
controller software. This includes HBA firmware, system drivers, and Fibre Channel switch firmware.
The SAN Visibility tool can assist you in this task because it automates the collection of this data and
provides you with a full report. You can collect the data manually, without using SAN Visibility, but
the manual process is more time consuming. To collect the data manually, complete the following
tasks:
• Identify all host servers
• Document all firmware versions
• Download the required HBA drivers, firmware and MPIO drivers
Collecting SAN configuration data using SAN Visibility
IMPORTANT:
SAN Visibility is only available for server-based management.
HP provides the SAN Visibility tool to automate the process of collecting SAN configuration data.
SAN Visibility collects configuration information from the Fibre Channel switches on your SAN. Any
information provided by devices when they log into the fabric is included. The raw configuration data
is collected, packaged, and sent to HP, where it is formatted into a complete report and returned to
you. You can then use the report to determine if any of your SAN components are not supported by
the latest controller software and must be upgraded or replaced.
HP StorageWorks Enterprise Virtual Array updating product software guide (XCS 09521000)
19
NOTE:
The version of SAN Visibility you are running may be a later version that what is shown below.
SAN Visibility requires Java 2 Runtime Environment (JRE) 1.5.0 Update 1 or higher. You can download
the most current JRE version from Sun's website:
http://www.sun.com/
Installing SAN Visibility
SAN Visibility is typically installed on the management server running HP Command View EVA.
1.
Download SAN Visibility and SAN Visibility documentation from the following website:
http://h18006.www1.hp.com/products/storageworks/san/index.html
Click SAN Visibility under Networking Solutions and Download Now.
2.
Double-click the downloaded file to launch the installation.
3.
Follow the on-screen instructions to install the software.
Using SAN Visibility
Before running SAN Visibility for the first time, you will need the following information:
• The IP addresses of the switches in your SAN connected to the storage system being upgraded.
You must have SNMP access to the switches to collect information from them.
• The name or IP address of your SMTP mail server to send reports automatically.
The following steps provide an overview of using SAN Visibility. For complete information about using
this tool, see the SAN Visibility online help.
1.
Double-click the SAN Visibility icon on the desktop.
The SAN Visibility welcome screen is displayed.
2.
20
Click OK to view the SAN Settings window.
Pre-upgrade tasks
3.
Select SAN Settings and enter the following information.
a.
Set your own SAN Name and Switch Group Name with Rename as follows:
Set your San Name in SAN Name. (You can use the default SAN Name, but HP recommends
that you change it to a name that is meaningful to you. This name is used when generating
reports, so it should be one that is easily recognized as being associated with the SAN on
which data collection will be done. If you see a Server Authentication error in the Messages
panel (bottom of screen), this is just notification of lack of a specific service; you can ignore
it.)
b.
Click Rename.
c.
Click Yes to confirm the name change.
d.
Enter a name in Switch Group Name. You can use the default fabric name, but HP
recommends that you change it to a name that is meaningful to you. This name is used when
generating reports, so it should be one that is easily recognized as being associated with
the fabric on which data collection will be done. (Mouse-over pop-ups provide useful
information.)
e.
Click Rename.
Your new switch group name (MySwitchGroup in this example) appears in the right panel
of your SAN Visibility screen.
f.
Click Yes to confirm the name change.

Select Customer Details and enter the following information:
a.
Enter your name in Name. This information is required.
b.
Enter your e-mail address in E-Mail to receive the completed report. This information is
required. It is not necessary to have an e-mail address connected to the EVA controller. You
should enter the e-mail address where you typically receive e-mail. You can enter multiple
email addresses in E-Mail by separating entries with a semicolon (;).
c.
Enter data in the remaining boxes as appropriate. This information is included in the reports,
but is not required.
d.
Click Next to save and proceed.
Pre-upgrade tasks
5.
Click Switch Settings and enter the following information.
a.
Enter the IP Address of the primary switch for the SAN for which you want a report.
Information will be collected for all devices connected to this switch.
b.
Clear Discover cascaded switches. This option automatically detects all switches connected
to the switch identified by the IP address. Including all the cascaded switches increases the
data collected for the report to include all the devices connected to all the switches. If you
want to include all the switches, leave this option selected.
c.
Enter the switch login and password if required. The Read Community value is obtained
from the switch.
d.
If you have created more than one switch group, use the Select Switch Group drop-down list
to select the fabric to which you want to add this switch.
e.
Click Discover Switch to discover the switch and activate the login and password. You should
see the extended switch information with IP addresses in the right-most panel.
f.
Click Add to add the switch to the reporting configuration.
Creating a report
Once you have configured SAN Visibility for data collection, you can create a report. There are two
methods for creating a report:
• Automatically—Automatically e-mails the data to HP when collection is complete. This requires
you to know the SMTP address of your mail server. If you have external e-mail access from your
environment, this is the preferred method.
• Manually—Requires you to manually send the data to HP to obtain a SAN Visibility report. If you
do not have external e-mail access, use this method.

Preparing an HP Continuous Access EVA environment for
upgrading
NOTE:
HP Continuous Access EVA is currently available with server-based management only.
Estimated time to complete: Varies depending on replication configuration
When to perform: As close as possible to the upgrade
When upgrading an EVA in an HP Continuous Access EVA environment, the following requirements
must be met. See HP StorageWorks Continuous Access EVA implementation guide for more information.
• Before you upgrade the controller software, you must upgrade HP Command View EVA (and
layered applications) to the required version on both the source and destination storage systems.
• Before you upgrade any storage system in an HP Continuous Access EVA relationship, ensure that
all storage systems in the storage network are running the same version of controller software.
This will ensure that when you upgrade one storage system, the storage network will have only
two versions of controller software. You cannot have more than two versions in an HP Continuous
Access EVA environment.
• During the time that the HP Continuous Access EVA storage systems are running different controller
software versions, you cannot make any configuration changes to your storage systems.
• You must perform the necessary upgrades to the storage systems in the HP Continuous Access
EVA relationship within 60 days (1440 hours) to make all controller software versions the same.
CAUTION:
In an HP Continuous Access EVA environment, do not begin the upgrade until the following conditions
are met. If you attempt to upgrade the controllers before the following conditions are met, controller
operation will fail.
• Ensure that no DR group is logging, merging, or copying. Furthermore, none of the DR groups
can be in a failsafe locked state.
1. Click the DR group icon in the Navigation pane.
2. Check the Log state in the DR Group Properties window.
• Ensure the connection between the storage systems is not compromised or failed.
1. Click the Data Replication folder in the Navigation pane.
2. Check the Connection State in the Data Replication Folder Properties window.
• All EVA storage systems must be running normally with fully functional controller pairs.
• After upgrading the first storage system (for example, the source), wait at least three minutes and
no more than 60 days before upgrading the second storage system. Ensure the preceding conditions
are met on the second system.
36
Pre-upgrade tasks
Upgrading disk drive firmware in an HP Continuous Access EVA environment
When upgrading disk drive firmware in an HP Continuous Access EVA environment, the following
requirements must be met. See HP StorageWorks Continuous Access EVA implementation guide for
more information.
• Verify that all DR groups are not failsafe mode enabled or in the failsafe locked state (DR group
failsafe mode should be disabled).
• Suspend replication and disable the intersite link or modify zoning to isolate the source array from
the destination array.
• Upgrade the disk drive firmware on the destination array
• Re-establish intersite link communication between the arrays and resume replication, allowing the
DR group merges to complete.
• Perform site failover.
• Suspend replication and disable the intersite link or modify zoning to isolate the source array from
the destination array.
• Upgrade the disk drive firmware on the new destination array (before site failover, this was the
source array).
• Re-establish intersite link communication between the arrays and resume replication, allowing the
DR group merges to complete.
• Perform site failback.
Saving storage system configuration information
Estimated time to complete: 10–15 minutes
When to perform: As close as possible to the upgrade
Before starting the upgrade, collect and save your current configuration information. This information
can be used to restore the existing configuration if necessary. The configuration data is saved to a
series of files stored in a location other than on the storage system. HP Storage System Scripting Utility
(called the utility) is used to collect configuration information.
This procedure can be performed from the management server where HP Command View EVA is
installed, or from any host running the utility to communicate with the HP Command View EVA.
NOTE:
You will need the IP address or name of your management server to run the utility.
1.
Double-click the HP Storage Systems Scripting Utility desktop icon to open the utility. When
prompted, enter Manager (management server name or IP address), User name, and Password.
2.
Enter LS SYSTEM to display the arrays managed by the management server.
3.
Enter SELECT SYSTEM system name, where system name is the name of the storage system.
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”.
HP StorageWorks Enterprise Virtual Array updating product software guide (XCS 09521000)
37
4.
Enter CAPTURE CONFIGURATION, specifying the full path and filename of the output files for
the configuration data.
The configuration data is stored in a series of one to five files, which are scripts. The file names
begin with the name you select, with the restore step appended. For example, if you specify a
file name of LargeEVA.txt, the resultant configuration files would be LargeEVA_Step1A.txt,
LargeEVA_Step1B, etc. Files which do not contain configuration information are not created
and therefore are not available to be restored.
The contents of the configuration files can be viewed with a text editor.
5.
Enter exit.
TIP:
When capturing the HP Command View EVA configuration, it is a best practice to specify the SAVE
ALL option. This helps to capture critical data such as the WWN, useful for rebuilding the array
configuration.
NOTE:
You cannot use the utility to restore a configuration that contains disk drives of different capacities.
You must manually restore that type of configuration. See the “Restoring an array configuration with
different disk sizes and types” section in HP StorageWorks Storage System Scripting Utility reference
for more information.
You can run the CAPTURE VALIDATE command for each of the files generated by the CAPTURE
CONFIGURATION command to determine if the file has been modified since the initial capture.
As a best practice, also use the following commands to collect configuration data:
• LS DISK_GROUP FULL
• LS HOST FULL
• LS VDISK FULL
If applicable, use the following commands as well:
• LS ISCSI_HOST FULL
• LS ISCSI_LUN FULL
For more information about using the utility or using the CAPTURE commands, see the HP StorageWorks
Storage System Scripting Utility reference. See “Required documentation” on page 12 for the link to
this document.

9.
The upgrade process begins and the Initializing firmware code load page opens (see Figure 15).
This page is displayed until the upgrade is complete and the controllers restart. During this interval
both controllers resynchronize and begin operating on the new controller software. Once the
resynchronization is complete, the controllers begin processing host I/Os.
Figure 15 Initializing software code load
.
Next, additional code within the storage system is updated, which can take up to 10 minutes to
complete. This includes firmware on the I/O modules in the disk enclosures. During this interval,
the Storage System Updating Firmware window opens (see Figure 16).
Figure 16 Storage system updating software
.
NOTE:
Because the I/O modules must be reset after being upgraded, allow 30 minutes for the I/O
module firmware upgrade to complete.
10. After 30 minutes, you must complete a power-off reset of the storage system including all disk
enclosures. You can either issue a power off from HP Command View EVA or from the controller
as follows:
a.
On the EVA4400, push and hold the enclosure power button on the rear of the controller
for a minimum of 4 seconds. The power button and the green LED start to blink when held
from 4 to 10 seconds.
On the EVA4400, while the power LED is blinking, release the power button. The button
continues to blink and the shutdown process completes.
If the EVA4400 does not perform a controlled shutdown, press and hold the power button
for 15 seconds. The power button turns amber when the array has shut down.

12. On the Initialized Storage System Properties window, verify the version of the storage system
software in the Version box. It should be 09521000.
Figure 17 Verifying XCS version after upgrading
.
Step 6. Upgrading disk drive firmware
Estimated time to complete: Varies depending on the number of disk drives that require upgrading
and the I/O load on the storage system. It can take 30 seconds to 3.5 minutes per drive to upgrade
the firmware.
Review the following guidelines and tips before proceeding with the upgrade:
• Server-based management is required to upgrade the disk drive firmware.
• Disks with Vraid0 cannot be upgraded online.
• Although it is not required that the disk drive firmware be upgraded when the controller software
is upgraded, it is strongly recommended that you perform these tasks together. The disk drive
firmware complements the operation of the controller software and, for best results, the two should
be used together.
HP StorageWorks Enterprise Virtual Array updating product software guide (XCS 09521000)
49
• When upgrading many (more than about 20) disk drives online, a loop may fail; to reduce the
chance of such a loop failure, upgrade about 15 or 20 drives, then pause the activity for several
minutes by navigating away from the upgrade. Continue after a few minutes. To proceed after
such a pause, review the controller logs to establish where you are in the upgrade process and
relaunch the online upgrade. The upgrade will start where it left off.
CAUTION:
Observe the following cautions when upgrading disk drive firmware:
• Do not power off any components or perform controller resynchs or reboots during an upgrade.
• Do not perform HP Continuous Access EVA copy/merge activities across sites, site failovers,
cloning, or grouping or ungrouping of disks during an upgrade.
• Do not add to or remove members from DR groups during upgrade.
• Ensure that you upgrade the disk drive firmware after you upgrade the storage system software.
• Perform your upgrade during times of low I/O to minimize the time it takes to revert information
back onto the drive after the upgrade.
• If an error occurs during the upgrade, the process stops and must be restarted to upgrade disks
that have not yet been upgraded. Any disks that were upgraded before the error occurred do not
have to be upgraded again. Check the logs to verify status. When you restart the process, it starts
at the next disk that needs the upgrade.
Upgrading firmware on all disks
Upgrade the disk drive firmware after you upgrade the controller software.
1.
Validate that adequate free space is available to manage disk failures that might occur after the
disk firmware upgrade.
2.
Reduce EVA maintenance overhead by setting the disk replacement timer to five minutes. Reset
the value to the default (60 seconds) once the upgrade process is complete. The longer setting
prevents triggering migration and revert processes as disks are upgraded.
3.
If you have not already done so, download the HP StorageWorks EVA Hard Disk Drive Bundle
zip file from the following web site:
http://www.hp.com/support/evadiskfirmware.
a.
Store the file to a known local directory. If you are running HP Command View EVA 9.x or
later, continue with step 4.
NOTE:
HP recommends that you use the default directory of C:\Program Files\
Hewlett-Packard\Sanworks\codeload. If you use a different directory, you
must enter the complete path when identifying the location of the firmware file.
b.
If you are running HP Command View EVA 8.x or earlier, unzip the bundled image file and
place the files in a directory where HP Command View EVA resides (HP recommends that
you use the default directory noted in Step 3a.)
Continue with step 4.

10. Click Next step.
The disk drive code load operation begins. A status page opens indicating the progress as each
disk drive is upgraded.
The disk drives are upgraded sequentially. Depending upon the I/O load on the storage system,
it can take 30 seconds to 3.5 minutes per drive to upgrade the firmware. The status is updated
at 45 second intervals, so you must wait to see which disk drives are complete.
CAUTION:
If you select any array in the Navigation pane to manage it, the disk drive upgrade stops.
For example, if 10 of 27 drives have completed the upgrade when you selected the array,
only those 10 drives will be upgraded. If you run a second disk drive upgrade, the Status
box on the Status window displays NO for the 10 drives that have been upgraded and the
remaining 17 drives are not upgraded.

503 Error: HP Command View EVA may be down when
a browser makes a request. The web server returns a 503
(No Service) error because it cannot access the page.
Retry the request when HP Command View
EVA is up.
Browser timeout: The appliance may be down or the web
server may be unavailable when a browser makes a request to HP Command View EVA. In this case, the browser
will time out internally.
Retry the request when the appliance and HP
Command View EVA are up.
Unknown storage system
Symptom
HP Command View EVA reports an unknown storage system for a storage system that should be
displayed.
HP StorageWorks Enterprise Virtual Array updating product software guide (XCS 09521000)
61
Cause of the error
HP Command View EVA may have lost communication with the controllers. Two possible scenarios
are:
• The HBA in the management server may have timed out commands to the controllers. See
“Unknown storage system—cause 1” on page 62 below.
• The controllers are running a version of XCS that HP Command View EVA does not recognize.
See “Unknown storage system—cause 2” on page 62.
Unknown storage system—cause 1
When the fabric is heavily loaded, the FC adapter in the management server may time out commands
to the controllers. If this occurs, the storage system appears in the Unknown state.
Corrective Action for Unknown Storage System—Cause 1
This scenario should correct itself in less than one minute. Alternately, you can perform a Rediscover
operation to initiate new commands to the controller.
Unknown storage system—cause 2
HP Command View EVA can only manage controllers that are running supported XCS versions.
Corrective Action for Unknown Storage System—Cause 2
Ensure that you are running the HP Command View EVA version that is compatible with XCS
09521000. See the “HP Command View EVA interoperability support” table in the HP StorageWorks
Enterprise Virtual Array compatibility reference to determine which version of HP Command View
EVA you should be running. Then, upgrade HP Command View EVA to a compatible version. See
“Required documentation” on page 12 for the link to this document.
No storage systems found
Symptom
HP Command View EVA does not display any storage systems, even though they are on the fabric.
Cause of the error
Several conditions can cause this symptom. Table 9 lists some possible causes of these errors and
their corrective actions.
Corrective action
Table 9 Possible causes and corrective actions when no storage system found
Possible Cause
Corrective Action
The management server may not be able to
communicate with either controller.
Check the connection configuration between the management server and
the controller pair. The management server must have a communication
path to both controllers in case one controller loses communications with
the server.
62
Troubleshooting
Possible Cause
Corrective Action
When HP Command View EVA is first starting
up, a password may be enabled on the controllers, but a password has not been entered
in HP Command View EVA.
Enter the correct password through HP Command View EVA or disable
the password on the controller.
The switches may not be correctly zoned,
making a storage system invisible to HP
Command View EVA.
Verify that switches are zoned correctly.
HP Command View EVA may have been restarted while there was a communication
failure between HP Command View EVA and
the controllers. When restart is completed,
the storage system that lost communication
will not be visible.
A storage system may not be visible to HP
Command View EVA because the controllers
are waiting for World Wide ID (WWID) to
be entered. This condition will occur if the
storage system has been uninitialized and
the cabinet is power cycled.
1.
Verify that the controllers are up and functioning properly.
2.
Check the cable connections between the management server and
the switch.
3.
Verify that switch zoning is correct.
4.
Click Discover.
Enter the WWID.
This may also occur if backend problems are
preventing access to the quorum drives. Once
communication is restored, the WWID along
with the checksum can be re-entered.
Solving security credentials configuration problems

Troubleshooting
Solving problems selecting a storage system
When selecting a storage system, ensure the status icon displayed for the storage system is a green
cluster symbol indicating good health. See Figure 24.
Figure 24 Status icon for a good storage system
.
If the status icon for the storage system is not green, it indicates a problem that must be corrected
before proceeding. Expand the navigation tree to locate the problem. Figure 25 illustrates a storage
system with a disk enclosure problem.

Solving problems disabling DR group failsafe mode
There are a number of issues that may occur with HP Continuous Access EVA. The following website
provides access to information for troubleshooting problems with HP Continuous Access EVA:

http://h20000.www2.hp.com/bizsupport/TechSupport/Home.jsp?&lang=en&cc=us&
prodTypeId=18964&prodSeriesId=471572&lang=en&cc=us
Click Troubleshoot a problem under Tasks for HP StorageWorks Continuous Access EVA Software.
Solving problems downloading the system software file
If you cannot download the system software file, right-click the link and save it to your desktop. Then
double-click the saved file on the desktop, which opens a window with the link to the file. Click the
link and save it to a directory.
NOTE:
The XCS image filename has an extension of .sss. The file name contains the controller model and
the XCS version. For example, 300_09521000.SSS is the name of the XCS 09521000 file for the
HSV300 and HSV300–S controllers. See Table 6 for details.
Invalid image file (Status code 21006)
If the XCS image file is the wrong image, an Operation failed message is displayed. See Figure 26.
Click OK to return to the Initialized Storage System Properties window.
Figure 26 Invalid image file (Status code 21006)
.
Bad image header (Status code 65)
HP Command View EVA sends the XCS controller software to the controller in segments. As each
segment is received, it is validated by the controller. HP Command View EVA monitors each segment
transfer and displays the transfer status information.
If a problem occurs, the process stops and HP Command View EVA displays the segment transfer that
was not successful. This is typically caused by a problem in the XCS controller software image file or
selection of the wrong image file. See Figure 27. If this error occurs, do the following:
1.
Click OK to return to the Initialized Storage System Properties window.
2.
Click Code load to begin the code load sequence again.
3.
Ensure that you select the correct image file, and continue the process.
If the process fails again with the same message, download the image file again and repeat the
process.
66
Troubleshooting
Verify that the correct name was selected. For the list of current image files, see Table 6.
Figure 27 Bad image header (Status code 65)
.
Solving problems if the storage system does not come back
online
The system software upgrade should take approximately 10 minutes to complete. If the storage system
does not come back within 10 minutes, check the following:
• Determine if the problem is with HP Command View EVA by performing the troubleshooting steps
in “HP Command View EVA problems” on page 59.
• Check any WEBES messages.
1. Double click on the System Event Analyzer icon on the management server to run WEBES.
2.
Click Full View under either System Log or the appropriate storage system in the left navigation
pane.
• Check the storage system event logs.
1. Run HP Command View EVA and log in.
2.
Select the storage system whose logs you want to view.
3.
Click View events to view the event logs that can be displayed.
If none of the above recommendations resolves the problem, contact your HP-authorized service
representative for help.
Solving problems with multiple resynchronizations
During the upgrade process, both controllers perform a resynchronization simultaneously. This invokes
a fast restart of the controllers — bypassing execution of lengthy hardware diagnostics. This fast restart
allows the controllers to complete the resynchronization sequence before the host timeout period
elapses and the host becomes aware that the storage system is unavailable.
If an event occurs that causes a second resynchronization while the upgrade resynchronization is still
in progress, the controller will terminate with a code of 0b 08 01 00. The following events cause
the controller to resysnchronize automatically:
• Initialization of the storage system
• Setting debug flags through the command line interface or WOCP
• Disk group hardware problem on a Vraid1 virtual disk, or attempted re-connection of a disk when
there is a disk group hardware problem
HP StorageWorks Enterprise Virtual Array updating product software guide (XCS 09521000)
67
• Bad Block Replacement (BBR) performed on a disk
• Memory allocation failure or other errors
Every effort should be made to ensure that none of these events occur during the upgrade process. If
controller termination occurs due to multiple resynchronizations, contact your HP-authorized service
representative for assistance.
