1 Overview of HP 3PAR Online Import for EMC Storage
HP 3PAR Online Import for EMC Storage manages the migration of data from a source EMC
Storage system to a destination HP 3PAR StoreServ Storage system. Using HP 3PAR Online Import
for EMC Storage, you can migrate EMC volumes and host configuration information to a destination
HP 3PAR StoreServ Storage system without changing host configurations or interrupting data access.
The terms storage system and array are used interchangeably throughout this guide, and may
refer to either the EMC Storage or HP 3PAR StoreServ Storage systems. The source in the migration
is the EMC Storage system, and the destination is the HP 3PAR StoreServ Storage system.
HP 3PAR Online Import for EMC Storage coordinates the movement of data from the source to the
destination while servicing I/O requests from the hosts. During the data migration, host I/O is
serviced from the destination HP 3PAR StoreServ Storage system. The host/volume presentation
implemented on the EMC Storage is maintained on the destination HP 3PAR StoreServ Storage
system.
Types of Data Migration
The HP 3PAR Online Import Software supports three types of data migration procedures. The
appropriate type of data migration depends on the objects being migrated and the migration type.
• Online—Migration type used when migrating a host or a volume presented to a host. During
online migration, all presentation relationships between hosts and volumes being migrated
are maintained. Host I/O to the data is not disrupted during an online migration.
• Minimally disruptive migration (MDM)—Migration type used when migrating a host or a
volume presented to a host. Host I/O is interrupted only during the time it takes to reconfigure
the host.
• Offline—Migration type used when migrating one or more unpresented volumes. During offline
migration, only the selected volumes are migrated. No hosts are migrated in this situation.
For additional information about online migration, see the support matrix for online import for EMC
Storage on HP SPOCK:
HP SPOCK (http://www.hp.com/storage/spock)
Understanding Which Data is Migrated
Data can be migrated by selecting a host or a volume on the source EMC Storage system. In
addition to the host or volume explicitly selected for an online migration or for MDM, other objects
can be included in the migration using implicit selection. A premigration process identifies the
relationship between hosts and presented volumes and selects all additional objects to completely
migrate the hosts. Consequently, the objects that will be migrated are the combination of the explicit
and the implicit selection and may lead to the migration of a large amount of volumes.
For example, selecting a single host results in migration of the following:
• The host as well as any volumes presented to it
• Any other hosts to which those volumes are presented
• Any volumes presented to those other hosts
IMPORTANT: The implicit selection of objects for migration occurs automatically and cannot be
modified. If the number of objects selected for migration becomes too large, migration might be
canceled before it is started. Once migration begins, it cannot be stopped. See “Aborting a
Migration” (page 55).
The maximum number of volumes that can be migrated with MDM or an online migration is 255.
If you have more offline volumes to migrate, rerun the migration steps for the additional volumes.
Types of Data Migration 7
The migration process selects objects to migrate using the following rules:
• Host—When selecting a single host or group of hosts with volume presentations, all the volumes
presented to the host(s) are migrated. In addition, any presentations the source volumes have
to other hosts will include those hosts and all of their presented volumes in the migration.
• Presented volumes—When selecting a volume or group of volumes with host presentations,
the selected volumes and the hosts to which they are presented are migrated. In addition, any
presentations the source hosts have with other volumes will include those volumes in the
migration.
• Unpresented volumes—Only the selected unpresented volumes are migrated. The offline
migration type is the only type available for unpresented volume migration.
NOTE: For more information about supported and unsupported configurations and about the
implicit selection of objects for migration, see “Migrations Supported by HP 3PAR Online Import
Utility for EMC Storage” (page 24).
EMC to HP 3PAR Migration Process
The process to migrate EMC Storage volumes to HP 3PAR StoreServ Storage system consists of
three parts:
• Premigration—Work done to define the source and destination storage system to a migration
definition. This work is not repeated when migrating a second host or additional volumes after
a first migration.
• Migration—Creating and executing the migration. Migration includes the process of unzoning
the destination storage system from the source storage system and removing the source storage
system after the migration is complete. This work is repeated for every migration.
• Post-migration—Removal of the online import setup.

3 Installation and Setup for Data Migration
This chapter describes requirements for an online import migration.
Configuration Rules for HP 3PAR Online Import for EMC Storage Support
For detailed information about ensuring that the source EMC Storage system and the destination
HP 3PAR StoreServ Storage system are configured properly for data migration, see the HP SPOCK
website:
HP SPOCK (http://www.hp.com/storage/spock)
The HP SPOCK website lists the supported system environment, including:
• The supported source EMC Storage systems and the associated firmware levels.
• The supported destination HP 3PAR StoreServ Storage systems and the associated HP 3PAR
OS levels.
• The supported host operating systems.
• The supported HBAs and the associated BIOS/firmware/driver versions to allow HP 3PAR
StoreServ Storage and EMC Storage coexistence.
• The supported configuration environments for installing HP 3PAR Online Import for EMC
Storage.
Installing EMC SMI-S Provider
The HP 3PAR Online Import Utility manages the EMC Storage systems through the EMC SMI-S
Provider software. The EMC SMI-S Provider is a component of EMC Solutions Enabler and requires
underlying EMC Solutions Enabler code to function correctly. However, installation of the base
EMC Solutions Enabler software does not include the EMC SMI-S Provider component.
Installation of the EMC SMI-S Provider includes only the necessary underlying EMC Solutions
Enabler code, not a full installation of EMC Solutions Enabler.
NOTE: It is technically possible to install the EMC SMI-S Provider on a machine where EMC
Solutions Enabler is already installed, but be aware that the EMC SMI-S Provider installation
uninstalls any existing EMC Solutions Enabler software and reinstalls only the subset of EMC
Solutions Enabler that comes with the EMC SMI-S Provider.
SMI-S Provider and VMAX require a Fibre Channel connection. VNX and CLARiiON CX4 connect
to the SMI-S Provider over an Ethernet Connection.
For VMAX, a VMAX gatekeeper device must be presented to the SMI-S server.
The EMC Solutions Enabler and the EMC SMI-S Provider are provided by EMC as separately
installable products and are available from the EMC Powerlink website. To install the EMC SMI-S
Provider software, follow these steps:
NOTE: The HP 3PAR Online Import Utility supports installation of the EMC SMI-S Provider only
on Windows.
See product release notes for full installation details:
SMI Provider Release Notes (https://developer-content.emc.com/developer/devcenters/storage/

Configuring EMC SMI-S Provider
Installing EMC SMI-S Provider is a prerequisite to allow remote software to connect to the EMC
Storage system.
You can either work directly on the EMC SMI-S Provider server or start a Remote Desktop Connection
to it.
1. Open a Windows command prompt on the server where the EMC SMI-S Provider software
is installed.
2. Change the directory to the location of the EMC SMI-S Provider installation. The default is:
C:\Program Files\EMC\ECIM\ECOM\bin
3. In the Windows command prompt, type C:\Program Files\EMC\ECIM\ECOM\bin>
testsmiprovider
4. Accept all default settings when prompted.
5. Attach the storage system to the SMI-S Provider.
NOTE: To migrate both a VMAX storage system and an EMC CLARiiON or VNX storage
system, follow both of the following steps.
a. For VMAX storage systems, any VMAX storage arrays connected to the SMI-S Provider
server will be automatically detected, provided that:
• SMI-S and VMAX have a Fibre Channel connection and are zoned.
• The gatekeeper LUN is presented to the SMI-S server.
If the VMAX does not show up, run the disco command to rescan for arrays. Proceed
to step 6, unless you intend to migrate volumes from an EMC CLARiiON or VNX storage
system.
b. To attach an EMC CLARiiON or VNX storage system to SMI-S Provider, use the addsys
command:
(localhost:5988) ? addsys

NOTE:
If your EMC SMI-S Provider has client IP filtering enabled, you need to add the IP address of the
HP 3PAR Online Import Utility server to the trusted IP address list.
To add an HP 3PAR Online Import Utility server to the EMC SMI-S Provider trusted IP address list:
1. Log into SMI-S ECOM administration page using one of the SMI-S user and password
configured:
• https://<SMI-S IP address>:5989/ECOMConfig
• http://<SMI-S IP address>:5988/ECOMConfig
2. Select the Client IP Filtering link on the ECOM Administration page.
3. Add the HP 3PAR Online Import Utility server IP address in the Trusted client’s IP field on the
Client IP Filtering page and click Execute to complete.

Migrations Supported by the HP 3PAR Online Import Utility for VMAX Only
IMPORTANT: The migrations shown here are supported only for VMAX.
NOTE: These configurations are not supported for EMC VNX or CLARiiON CX4:
• The createmigration command checks for these configurations and blocks migrations of
unsupported configuration.
• In most cases, unsupported configurations are those in which multiple LUNs that span multiple
storage groups are to be added to the migration (either explicitly or implicitly).
• It is an error when the added storage groups do not contain exactly the same LUNs.

4 Preparing for Data Migration
Use the information in this chapter to ensure all necessary tasks are performed and considerations
are understood before beginning a migration.
Data Migration Considerations
Before migrating data using 3PAR Online Import for EMC Storage, be aware of the following
general considerations, system requirements, and other tasks associated with planning, host
configuration, and network and zoning requirements.
General Considerations
• LUNs and hosts can be implicitly added to the migration, even if they are not specified by the
input.
• Only volumes presented to Fibre Channel hosts can be migrated. Volumes presented to iSCSI
or FCoE hosts cannot be migrated.
• All hosts and LUNs in the source groups are migrated. If there are multiple hosts or LUNs in
the configuration, they all end up in a single CPG.
• When a cluster is being migrated, all the hosts in the cluster must be moved at once.
• HP 3PAR host persona/host OS: EMC Storage arrays do not implement specific OS settings
when registering host initiators on the EMC Storage array. During migration, online import
cannot determine the host OS when migrating the hosts to the HP 3PAR StoreServ Storage.
All hosts that are being created on the HP 3PAR StoreServ Storage during EMC migration
are set by default to host persona 2. Consider changing the HP 3PAR host persona/host OS
to the appropriate setting before enabling access to the HP 3PAR array.
• LUNs identified for migration should not be part of any other current application jobs. For
example, make sure the LUN is not part of a replication job or backup job.
• The LUN limit for offline migrations is 25. The maximum number of volumes that can be
migrated with MDM or an online migration is 255. See “Aborting a Migration” (page 55)
• A createmigration command cannot simultaneously contain a host and a LUN for
migration.
• Only one createmigration is allowed at a time because 3PAR Peer Ports can only be in
one EMC Storage Group at a time.
• When a volume on the source EMC Storage system is migrated, an SCSI-3 reservation is
installed to prevent any unwanted management changes to the volume during the migration.
The SCSI-3 reservation remains on the volume after the migration.
• Only one EMC Storage system at a time can be attached as a source to the destination
HP 3PAR StoreServ Storage system.
• EMC volumes cannot be migrated if they are larger than 16 TB, the maximum volume size on
the HP 3PAR StoreServ Storage system.
• EMC volumes cannot be migrated if they are less than 256 MB, the minimum volume size on
the HP 3PAR StoreServ Storage systems.
• Snapshots become standalone objects on the destination HP 3PAR StoreServ Storage system.
LUNs that have been migrated cannot be part of a replication group.
