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 virtual disks and host configuration information to a destination HP 3PAR StoreServ Storage system without changing host configurations or interrupting data access.
virtual disks have to other hosts will include those hosts and all of their presented virtual disks in the migration. • Presented virtual disks—When selecting a virtual disk or group of virtual disks with host presentations, the selected virtual disks and the hosts to which they are presented are migrated. In addition, any presentations the source hosts have with other virtual disks will include those virtual disks in the migration.
6. Remove PowerPath from server if present. Update host native multipath software, finish zoning, and shutdown host. For Windows: “Update Host Multipath Software and Unzone from Source EMC Storage System” (page 33) For Linux: “Update Host Multipath Software and Unzone from Source EMC Storage System” (page 35) Migration 1.

3 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. Considerations When Migrating Data Before migrating data using 3PAR Online Import for EMC Storage, be aware of the following: General • HP recommends that a single host be migrated at a time, unless a cluster is being migrated, in which case all the hosts have to move at once.
Planning for Migration Advanced planning ensures that you achieve the desired results when migrating data. • It is a recommended best practice to make a backup of your host/data before starting a migration. • To perform a minimally disruptive migration process, a maintenance window outage is required. Please plan accordingly. • Identify which virtual disks and hosts will be migrated.
IMPORTANT: If you unzone the host and EMC Storage system but don't reconfigure the host DSM, the host/cluster will experience an outage because it will not be able to communicate with the destination HP 3PAR StoreServ Storage system. Network and Fabric Zoning Requirements Data migration requires the necessary zoning to create paths between the source and destination storage systems and any hosts involved in the migration. The data paths used are shown in Figure 1 (page 25).
Pre-Migration Steps Perform these steps to prepare for migration. Zoning the Source EMC to the Destination HP 3PAR StoreServ Storage System The correct zoning must be created between the source EMC Storage system and destination HP 3PAR StoreServ Storage system at every stage of the migration operation. The following zoning rules apply: • There must be two unique paths between the source and destination storage systems.
When migrating a Windows Server 2012 active/passive cluster, maintenance mode must be set on the cluster disks to clear SCSI reservations on the disks. Because the quorum disk cannot be set in the maintenance mode, it must be set to the offline mode to clear the SCSI reservations. Then, the cluster service must be stopped on ALL nodes. For active/active clusters, offline all disks. For more information, see Microsoft documentation on how to start/stop the cluster services.
2. Enter the showsource command to verify the source storage system information. Example 2 showsource command >showsource –type VNX NAME CLARiiON+APM00125345014 28 Preparing for Data Migration TYPE UNIQUE_ID VNX 50067890BEE0177F FIRMWARE MANAGEMENT_SERVER 05.32.000.5.201 10.10.10.
Identify the Destination Storage System To identify the destination procedure: 1. From the HP 3PAR Online Import Utility execute the adddestination command. Example 3 adddestination command >adddestination –type 3PAR –mgmtip 10.10.10.10 –user 3paradm –password 2Password >SUCCESS: Added destination storage system 2. Enter the showdestination to verify the destination storage system information.
Create the Data Migration Task The data migration task identifies the details on the source and destination storage system required to perform a migration and does the initial preparation required for the data migration: • On the source storage system, the HP 3PAR initiator is added into a storage group where host/volumes being migrated are located. The Host Name of the 3PAR initiator is “UNKNOWN”. The Initiator Name appears as the WWN of the peer port on the 3PAR.
Example 6 showmigration command >showmigration -migrationid 1395864499741 MIGRATION_ID TYPE SOURCE_NAME STATUS(PROGRESS)(MESSAGE) 1395864499741 MDM CLARiiON+APM00123452867 preparationcomplete(100%)(-NA-) 3. DESTINATION_NAME 3par_7200_DCA_01 START_TIME END_TIME Wed Mar 26 13:08:19 PDT 2014 -NA- Enter the showmigrationdetails command to verify the volumes being migrated. In the preparation stage the progress for each volume will be 0%.
4 Performing the Data Migration Data migration can be performed by selecting a host or a virtual disk. The sequence of tasks differs depending on the Operating System of the hosts you are migrating. CAUTION: You cannot stop a migration once it has started. Migrating a Windows Host The minimally disruptive migration (MDM) process is used when migrating a Windows host with a source EMC Storage system.
Update Host Multipath Software and Unzone from Source EMC Storage System CAUTION: PowerPath must NOT be installed during the migration process. Native MPIO must be managing the paths. CAUTION: Stop all applications before removing PowerPath. Applications should be restarted after migration is started. 1. Perform the following steps on the Windows host: a. Remove EMC PowerPath Multipath software from host following the PowerPath documentation instructions.
Bring the Windows Host Back Online 1. Once the import has started for all volumes, bring the Windows host that was shutdown back online. NOTE: In order to verify the import has started for all volumes, issue the showmigrationdetails command and confirm TASK_IDs are available for all volumes.
Update Host Multipath Software and Unzone from Source EMC Storage System CAUTION: PowerPath must NOT be installed during the migration process. Native device-mapper-multipath must be managing the paths. CAUTION: Stop all applications before removing PowerPath. Applications should be restarted after migration has started. Perform the following steps on the Linux host: 1. Remove EMC PowerPath Multipath software from host following the PowerPath documentation instructions. 2.
2. To view the status of the migration, execute the showmigration command. Example 13 showmigration command >showmigration -migrationid 1396643904320 MIGRATION_ID TYPE SOURCE_NAME DESTINATION_NAME 1396643904320 MDM CLARiiON+APM00125127014 unpresenting(1%)(-NA-) TIP: START_TIME 3par_7200_DCB_01 END_TIME STATUS(PROGRESS)(MESSAGE) Fri Apr 04 16:38:24 EDT 2014 -NA- The final status on successful completion will indicate “success”.

5 Performing an Offline Migration Prerequisite Component Installation 1. Check the Single Point of Connectivity Knowledge (SPOCK) website to confirm proper configuration. “Configuration Rules for HP 3PAR Online Import for EMC Storage Support” (page 9) 2. Install EMC SMI–S Provider “Installing EMC SMI-S Provider” (page 9) 3.
Preparing Host for Migration To prepare for a successful migration, stop all applications on the host that may be accessing the LUNs to be migrated. This also includes any replication and backup applications on the LUNs. Next, set the LUNs to be migrated to an offline/unmounted state. NOTE: Any applications and services that may automatically start with a reboot should be disabled until after the migration has started and the documentation instructs you to bring your host back online.
Required Information Source Storage System: • IP address of the SMI-S Provider that is managing the source EMC Storage system where the volumes are being migrated. ◦ If the SMI-S server is managing more than one source EMC Storage system and you only want to identify one of them you need to know the WWN of the source storage system. • Username and password for the EMC SMI-S Provder. • Port to access the EMC SMI-S Provider. ◦ Secure port default 5989. ◦ Non-secure port default 5988.
Identify the Source Storage System To identify the source storage system: 1. From the HP 3PAR Online Import Utility execute the addsource command. NOTE: Use your local host username and password credentials. Example 18 addsource command >addsource -type VNX -mgmtip 10.10.10.10 -user admin -password 1Password -uid 50067890C6E059EE >SUCCESS: Added source storage system 2. Enter the showsource command to verify the source storage system information.
Create the Data Migration Task The data migration task identifies the details on the source and destination storage system required to perform a migration and does the initial preparation required for the data migration: • On the source storage system, the HP 3PAR initiator is added into a storage group where host/volumes being migrated are located. The Host Name of the 3PAR initiator is “UNKNOWN”. The Initiator Name appears as the WWN of the peer port on the 3PAR.
Example 23 showmigration command >showmigration -migrationid 1395864499741 MIGRATION_ID TYPE SOURCE_NAME STATUS(PROGRESS)(MESSAGE) 1395864499741 2014 -NA- 3. DESTINATION_NAME offline CLARiiON+APM00123452867 preparationcomplete(100%)(-NA-) START_TIME 3par_7200_DCA_01 END_TIME Wed Mar 26 13:08:19 PDT Enter the showmigrationdetails command to verify the volumes being migrated. In the preparation stage the progress for each volume will be 0%.
4. Exporting the LUNs to the host on the HP 3PAR StoreServ Storage system. Using the HP 3PAR management tool, perform the following: 1. Create host entry on the HP 3PAR StoreServ Storage system (if it does not exist). 2. Set the host OS to the appropriate value (this will set the correct persona). 3. Add host WWN to host entry. 4. Export the migrated LUN to the newly created host entry.
6 Removing a Storage System from SMI-S Provider This procedure will remove a system from the migration list after the migration has completed or if you have added the wrong system for migration. CAUTION: You cannot remove a system or abort the migration during the migration process. You can only remove the system before migration begins are after it has completed. 1. In the SMI–S CLI, type the ein command.
7 Troubleshooting The following are problems you may encounter when using EMC to HP 3PAR StoreServ Online Import. NOTE: During the migration process, it is important to remember that the data continues to be served from the source EMC Storage system until the import of each volume is complete. If host errors occur, both the destination HP 3PAR StoreServ Storage system and the source EMC Storage system should be checked for potential problems.
OIU Service The OIU service must be stopped before getting the logs or changing the logging level and restarted afterward. To do this, go to WindowsComputer→Manage screen, right-click on the Service Name and select stop/start. OIU Server Logs and Output When an issue occurs, get all the OIU server logs and output to assist with troubleshooting. Use the following action and commands to get the logs and output.
SMI-S Provider Server Logs and Output When an issue occurs, get all the SMI–S Provider server logs and output to assist with troubleshooting. Use the following action and commands to get the logs and output. • Go to this file location to get the SMI–S Provider logs: ◦ • Windows: C:\Program Files\EMC\ECIM\ECOM\log\cimomlog Get SMI–S Provider output by issuing these commands: ◦ dv command to see SMI–S Provider version information and lists of storage systems being managed by SMI-S Provider.
4. If the SMI-S Provider ECOM login page does not appear, check the following: • Make sure you have the correct IP address for SMI-S Provider server. • Make sure you are using the correct Port for SMI-S Provider server. Login to the SMI-S Provider server and look at the port configuration file which shows which ports are enabled for use and whether they are expecting a secure or unsecure connection. ◦ • Windows: C:\Program Files\EMC\ECIM\ECOM\conf\Port_settings.

Initiating a createmigration command to create a host on a destination produces an error message Example 34 createmigration command error >showmigration -migrationid 1397250721519 MIGRATION_ID TYPE SOURCE_NAME DESTINATION_NAME START_TIME END_TIME STATUS(PROGRESS)(MESSAGE) 1397250721519 MDM CLARiiON V400 Fri Apr 11 16:12:01 CDT 2014 -NApreparationfailed(-NA-)(OIUERRPREP1014:Error creating host on destination;) Solution: This problem can occur when the host is already added to the destination.
Workaround: Before beginning the migration, rename the host so that there are no spaces in the name and the name length does not exceed 31 characters. Error logging into OIU CLI Problem: “ERROR: Could not process your request. Illegal character in authority at index...” on login to OIU CLI caused by trailing space on the IP Address. Solution: Re-open the OIU CLI and enter the IP Address without any spaces at the end. OIU:createmigration results in “ERROR: OIUERRAPP0000 An unexpected error occurred.
Solution: Upgrade the 3PAR storage system to a supported version. An “unexpected error” message when destprov/destcpg are not specified for all LUNs Problem: ERROR: OIUERRAPP0000 on createmigration using srcvolmap.
