Upgrading a VA 7100/7400
to a VA 7410/7110
This document describes the steps involved in upgrading a VA 7100 or
VA 7400 array to a VA 7410 or VA 7110 array. This procedure should only
be performed by HP service trained personnel.
Caution All upgrades to a VA 7410/7110 require a full back up of all
data. The array is reformatted during the upgrade, which will
destroy all data on the array. It is the customer’s responsibility to
ensure that all data on the array is backed up before the
upgrade is performed.
The upgrade procedure involves the following steps:
1 Backup all data on the array.
2 Gather array configuration information.
3 Upgrade disk firmware if necessary.
4 Power down the array.
5 Upgrade the array hardware.
6 Configure the upgraded array.
7 Create the LUN configuration.
8 Use previously saved data to recreate the host port behavior table and the
Secure Manager table.
9 Restore all data to the array.

Information You Will Need
In addition to this document, you will need the following information:
■ HP StorageWorks Virtual Array Installation Guide. The steps in this guide
will be used when bringing the upgraded VA 7410/7110 back on line.
■ HP StorageWorks Virtual Array User and Service Guide . The detailed
instruction for many of the hardware replacement procedures included in
the upgrade are included in this book.
These guides can be downloaded from the Manuals section of the following
web site:

■ Quick Connect Guide(s) and Connectivity Streams Documents - these
documents provide detailed, operating system-specific configuration and
installation information. These guides can be downloaded from the
following internal HP web site:
http://hpso.rose.hp.com/spock/#NASL
Planning the Upgrade
Here are some things to consider when planning the upgrade:
■Changing the physical configuration - because the entire array must be
powered off to perform the upgrade, this is an ideal time to move or
rearrange the array hardware components. This may be necessary if
additional disk enclosures are being added as part of the upgrade.
Note The remaining items apply to the VA 7410 only.
■Capacity requirements - the VA 7410 requires more disk capacity for
image disks. This additional capacity must be available on the array. If a
VA 7100 is being upgraded, the impact on available capacity may be
substantial because of the two redundancy groups used on the VA 7410.
Before upgrading a VA 7100, a careful assessment should be made of
how much additional capacity will be required on the array to create the
desired LUN configuration.
■LUN configuration - when upgrading a VA 7400, the impact on the LUN
configuration will be minimal because the VA 7410 and VA 7400 both use
two redundancy groups. Upgrading a VA 7100 will have more impact
because the array is moving from one redundancy group to two. The LUN

Upgrading a VA 7100/7400 to a VA 7410/7110 3
configuration will have to be modified to take advantage if the
performance benefits offered by the VA 7410.
■Host connectivity - the VA 7410 provides additional FC ports for host
connectivity. Make sure the environment has the capacity to accommodate
the additional connections.

Preparing for the Upgrade
Gather the Required Hardware Components
The following hardware components are required when upgrading the array.
Before beginning the upgrade, make sure all necessary components are
available. The parts involved in the upgrade will vary depending on the
magnitude of the upgrade.
Note Use the product number when ordering parts for the upgrade.
Do not use replacement or exchange parts for performing the
upgrade.
Replacing Fibre Channel Cables When Upgrading a VA 7100
The VA 7100 uses large form factor SC Fibre Channel cables. When
upgrading to a VA 7110/7410, it will be necessary to replace these cables
with small form factor LC cables. Refer to Table 21 in the
HP StorageWorks
Virtual Array User and Service Guide
for a list of supported LC cables.
Checking for VA 7410/7110 Updates

Backup All Data on the Array
A complete backup of all data should be performed on the array that is being
upgraded. The upgrade process involves formatting the array, which will
destroy all data. It is the customer’s responsibility to backup all data on the
array.
Determine if Consulting Services May Be Needed
Consulting services are available for optimizing the use and performance of
the VA 7410/7110. Because of the additional features offered by the
VA 7410/7110, the customer may be interested in purchasing some of these
services. If the customer is unfamiliar with the services available, direct them to
the following web site for more information:
http://www.hp.com/hps/tech/storage/
Gather Array Configuration Information
If the existing array configuration will be recreated on the upgraded array, all
important array configuration information should be saved. This will facilitate
re-establishing the correct configuration on the upgraded array. If a new
configuration will be established, you may not need to save and reuse all of
the array configuration.
Note The commands used to retrieve and save the configuration
information redirect the output to the specified file. After
executing a command, view the file and make sure the content
looks correct before proceeding to the next command. The file
names used are suggestions. Any meaningful file names can be
used.
Because the array will be formatted, do not store the
configuration files on a LUN on the array.

6 Upgrading a VA 7100/7400 to a VA 7410/7110
1 Save the state of the array:
armdsp <array_id> > armdsp_<array_id>
armdsp -a <array_id> > armdsp_a_<array_id>
2 Save a list of any feature licenses that are installed:
armfeature -r <array_id> > armfeature_<array_id>
3 If the host port behavior table is being used, save the table:
armhost -r -f armhost_<array_id>.txt <array_id>
4 If the Secure Manager LUN security table is being used, save the table:
armsecure -r -f armsecure_<array_id>.txt -p password
<array_id>
Upgrade Disk Firmware
The VA 7410/7110 uses a 2 Gbit back-end. All disks that will be used in the
upgraded array must have firmware that supports the 2 Gbit transfer speed.
The upgrading of disk firmware is described in a Service Note available on the
following internal HP web site:
http://snserver.mayfield.hp.com/products/A6183A/
Power Off the Array
When upgrading to a VA 7410/7110, it is best to avoid an image disk
conflict. This occurs when the VA 7410/7110 controllers find a valid image
from a VA 7100 or VA 7400 during power on. Because the images are
incompatible, an abterm error will occur if a valid image disk is found.
To avoid this situation, the array enclosure must be powered off without
performing a shutdown. This ensures that the image disks on the array are
invalid. When the VA 7410/7110 controllers are powered on, they will not
find a valid image and an image conflict (and the resulting abterm) will not
occur.
1 Simultaneously disconnect both power cords from the array controller
enclosure.
2 Set the array controller enclosure power/standby switch to the OFF
position.
3 Power down any disk enclosures.

Upgrading the Array Hardware
Upgrading the original array to a VA 7410/7110 involves replacing
controllers and LCCs on the original array. The procedure may also involve
adding new disk enclosures if the array capacity is being increased.
Note Make sure you have a copy of the
HP StorageWorks Virtual
Array User and Service Guide
available. The detailed steps for
the procedures involved are covered in this book and are not
duplicated here.
Disconnect Fiber Cabling
1 Disconnect all fiber cabling from the array enclosure.
2 Disconnect all fiber cabling from the disk enclosures on a VA 7400.
Replace the Array Controllers
The controllers in the array enclosure must be replaced with VA 7410 or
VA 7110 controllers.
Note Before replacing the controllers, check the BATTERY LED on each
VA 7410/7110 controller to ensure the LED is off. If the LED is
flashing, it indicates that the battery is supplying power to the
NVSRAM. If the LED is flashing, remove the battery from the
controller, wait a few seconds, and reinstall it. This will ensure
that the NVSRAM contents are cleared.
1 Remove both controllers from the array enclosure.
2 If the cache DIMMs will be used on the VA 7410/7110 array, remove the
DIMMs from the controllers.
Note 256 MB DIMMs are not supported on the VA 7410/7110.
3 Install cache DIMMs on the VA 7410/7110 controllers. The minimum
cache configuration for the VA 7410/7110 is 1024 MB per controller (two
512 MB DIMMS or a single 1024 MB DIMM).
4 Install the VA 7410/7110 controllers in the array enclosure.

8 Upgrading a VA 7100/7400 to a VA 7410/7110
Replace the Disk Enclosure LCCs
If the original VA 7400 array included DS 2400 disk enclosures, the LCCs must
be replaced with DS 2405 LCCs.
1 Remove both LCCs from the disk enclosure.
2 Install the DS 2405 LCCs in the disk enclosure.
Set FC Loop Speed Switch (Upgrading a VA 7400 with DS 2405 Disk
Systems)
When upgrading a VA 7400 that includes DS 2405 Disk Systems, the FC Loop
Speed switch on the disk enclosure LCCs must be set to 2GB/s. Failure to set
the switch on both LCCs in each disk enclosure will disrupt the FC loop and
cause the entire array to malfunction.
Install New Disk Enclosures
If the capacity of the array will be increased by adding additional disk
enclosures, they should be added now.

Configuring the Upgraded VA 7410/7110 Array
The process of configuring the upgraded VA 7110/7410 is the same process
used for installing a new array. Go to the
HP StorageWorks Virtual Array
Installation Guide
and perform step 3 through step 19. Any differences in the
steps when performing the upgrade are identified below.
Note The step numbers in this section refer to the corresponding step
numbers in the
HP StorageWorks Virtual Array Installation
Guide.
Step 6. Power-on the array controller enclosure
Because the array does not detect any valid image disks, the array status will
be No Maps. Format the array to create the maps using the following
command:
vfpfmt
Note Make sure that the disk enclosures are not connected to the
array controller enclosure and operating when performing the
format. This will ensure that the image disks selected for the
array will be in the controller enclosure.
Handling an abterm 70.3.2
If the array detects a valid image disk from the original array, a looping
abterm 70.3.2 will occur due to the incompatible disk image. To clear the
error, perform the following steps:
1 Power off the array enclosure.
2 Disconnect all disks from the backplane by sliding them out of the
enclosure one inch.
3 Power on the array enclosure. The array status should be Not Enough
Disks.
4 Install the disks back into the controller enclosure.
5 Format the array to create the image disks:
vfpfmt
The array status should now be Ready and you can proceed with step 7.

10 Upgrading a VA 7100/7400 to a VA 7410/7110
Step 12. Format the array controller enclosure
Skip this step because the array has already been formatted.
Step 19. Build the Host Port Behavior Table
The host port behavior table is stored on the array mid-plane and it should not
be necessary to recreate the table. However, it is recommended that you read
the table from the array and check it to make sure it contains the proper
entries. Use the following command to read the table to the file identified by
filename:
armhost -r -f filename array-id
Step 21. Build the Secure Manager LUN Security Table
If the Secure Manager LUN security table was saved from the original array,
use the configuration information to restore the LUN security table. Use the
following command to write the LUN security table to the array from the file
saved earlier:
armsecure -w -f armsecure_<array_id>.txt -p password
<array_id>
Restore Array Data
After the LUN configuration has been restored, the data can be restored from
the backup medium.
