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 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.

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.
System Requirements NOTE: For detailed information about ensuring 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.
Table 16 Multipathing software by operating system OS Multipathing Software Windows Server 2012 Windows native MPIO Windows Server 2008 R2 Windows native MPIO Windows Server 2003 HP MPIO1 Linux device-mapper 1 For Windows Server 2003, HP uses a specific DSM: HPMpioDSMFor3Par_Kit_Ver_1_0_23_1 After the migration preparation phase is complete, the host might need to be shut down and reconfigured to use the native multipathing software DSM for MDM.
Figure 1 Data migration zoning Premigration Steps Perform these steps to prepare for migration. Zoning the Source EMC Storage to the Destination HP 3PAR StoreServ Storage System The correct zoning must be present 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.
A on the EMC, and zone the peer port on node 1 on the HP 3PAR StoreServ Storage system to controller B on the EMC Storage system. 3. Verify that the EMC Storage system can detect both ports on the HP 3PAR StoreServ Storage system. Ensure that the peer port WWNs appear in the discovered port list. • To check peer port connections using VMAX, follow these steps: a. Issue the following command: symaccess -sid list logins b.
NOTE: Any applications and services that may automatically start with a reboot should be disabled until after the migration has started and documentation instructs you to bring your host back online. For Hyper-V running on Windows Server 2008 R2, follow these steps to prepare the host for migration: 1. Stop all applications currently running on the virtual machine. 2. Shut down the virtual machine using Failover Cluster Manager.
Required Information EMC Storage source system: • IP address of the EMC SMI-S Provider that is managing the source EMC Storage system from which the volumes are being migrated. ◦ If the SMI-S server is managing more than one source EMC Storage system, and you want to identify only one of them, you need to know the WWN of the source storage system. • User name and password for EMC SMI-S Provider. • Port to access EMC SMI-S Provider. ◦ Secure port default 5989. ◦ Non-secure port default 5988.
Identifying the Destination Storage System To identify the destination procedure, follow these steps: 1. From the HP 3PAR Online Import Utility, execute the adddestination command. Example 3 adddestination command >adddestination –mgmtip 10.10.10.
◦ One initiator group “parent” is added and associated to the HP 3PAR peer port initiator groups. The naming convention is: OIU__IG ◦ One port group is added, containing the required ports based on the original masking views. The naming convention is: OIU__PG After all of these groups have been created and populated, a migration masking view is added and associated to the migration storage group, initiator group, and port group.
To create the migration for a given migration type using the createmigration command, see: ◦ Online migration, if EMC PowerPath is installed: “Online Data Migration with Removal of EMC PowerPath” (page 40), steps 5–8 Online migration, if EMC PowerPath is not installed: “Online Data Migration with Native device-mapper Multipath” (page 45), step 6 ◦ ◦ MDM – Windows: “Creating the Data Migration Task” (page 51) – Linux: “Creating the Data Migration Task” (page 56) – Hyper-V: “Creating the Data Migrat
5 Performing Online Data Migration Using Linux If EMC PowerPath is installed, it must be uninstalled, and device-mapper must be used to configure multipathing. Follow the online data migration procedure in “Online Data Migration with Removal of EMC PowerPath” (page 40). If EMC PowerPath is not installed, follow the online data migration procedure in “Online Data Migration with Native device-mapper Multipath” (page 45).
a. b. c. d. 6. Close all applications on the host. Unmount the application file systems, bring offline any raw devices (if configured), and deactivate any volume groups where Logical Volume Manager is in use. For a cluster, stop the cluster services, and then stop the cluster. Uninstall EMC PowerPath from the host, following the EMC PowerPath documentation instructions. Configure native device-mapper multipath on the host: a. If multipath is not already installed, install it. b.
IMPORTANT: In Linux, EMC PowerPath devices are presented as /dev/emcpower* (for example, /dev/emcpowera). EMC PowerPath removal in Linux also removes this device type. This changes when the Linux native device-mapper multipath assumes management of these devices. For example, before EMC PowerPath removal, consider combining /dev/sdb and /dev/sdc into /dev/emcpowera. After EMC PowerPath removal, /dev/sdb and /dev/sdc would be represented by /dev/mpathx.
11. HP recommends that you change the HP 3PAR host persona/host OS to the appropriate setting before enabling access to the HP 3PAR array. NOTE: 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. 12.
Example 12 Unzoning an RHEL 5.x host from the source array.
Example 14 Removing a path to a storage device in RHEL 5.
Example 16 Using addsource to add a source storage system for online data migration >addsource -type VMAX -mgmtip 10.10.10.10 -user admin -password adminpw -uid xxxxxxxxxxxxxxxx >SUCCESS: Added source storage system. > >showsource NAME GEMENT_SERVER TYPE OPERATIONAL_STATE SYMMETRIX+000194901212 10.10.10.10 3.

HP recommends that you change the HP 3PAR host persona/host OS to the appropriate setting before enabling access to the HP 3PAR array. NOTE: 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.
Example 21 Unzoning an RHEL 5.x host from the source array.
Example 23 Removing a path to a storage device in RHEL 5.
6 Performing MDM Using a Windows Host The MDM process is used when migrating a Windows host with a source EMC Storage system. The host DSM must be updated to communicate with the destination HP 3PAR StoreServ Storage system, and the host must be shut down briefly. Host I/O is interrupted only during the time it takes to reconfigure the host. Required Information Source storage system: • WWN of the source EMC Storage system from which LUNs are being migrated.
1. From the HP 3PAR Online Import Utility, execute the createmigration command. Example 25 createmigration command >createmigration -sourceuid 50067890C6E059EE -srchost "HPDL585-01" -destcpg "FC_r5" -destprov thin -migtype MDM >SUCCESS: Migration job submitted successfully. Please check status/details using showmigration command. Migration id: 1395864499741 NOTE: Be aware, the createmigration command may take several minutes to complete.
IMPORTANT: If you are uninstalling EMC PowerPath from a Windows host where the host is booting from SAN, you will be prompted to restart before removal is completed. This restart is required and must be completed. After removal, you will be prompted to restart the host in order for the changes to take effect. Do not restart at this point. 2. The removal of EMC PowerPath Multipath software may have also disabled the MPIO installation but not removed it.
NOTE: 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. Starting the Data Migration from Source EMC Storage System to Destination HP 3PAR StoreServ Storage System 1.
3. 4. Check the disk status by pointing to diskpart.exe or by opening Disk Manager. All applications and services can now be restarted and the host may resume normal operations (including first restarting the cluster if applicable). Viewing Migration Status Viewing all Migrations To view all migrations, use the showmigration command from the HP 3PAR Online Import Utility.
7 Performing MDM Using a Linux Host The MDM type can be used when migrating a Linux host with a source EMC Storage system. The host must be shut down briefly during MDM. Host I/O is interrupted only during the time that the host is shut down. If you are performing online migration, see “Performing Online Data Migration Using Linux” (page 40). Required Information Source storage system: • WWN of the source EMC Storage system from which LUNs are being migrated.
1. From the HP 3PAR Online Import Utility, execute the createmigration command. Example 32 createmigration command >createmigration -sourceuid 50067890C6E059EE -srchost "HPDL585-01" -destcpg "FC_r5" -destprov thin -migtype MDM >SUCCESS: Migration job submitted successfully. Please check status/details using showmigration command. Migration id: 1395864499741 NOTE: Be aware, the createmigration command may take several minutes to complete.
c. d. 2. 3. Unmount the application file systems, bring offline any raw devices (if configured), and deactivate any volume groups where Logical Volume Manager is in use. Uninstall EMC PowerPath from the host, following the EMC PowerPath documentation instructions. Zone the host to the destination HP 3PAR StoreServ Storage system to establish communication. Using the HP 3PAR Management Console, verify host-to-destination connectivity by confirming host initiator login on the HP 3PAR StoreServ Storage.
Example 36 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”. Bringing the Linux Host Back Online To bring the Linux host back online, follow these steps: 1.
Example 40 Linux Host with Multiple LUNs # multipath -v2 Apr 10 14:31:11 | mpatha: ignoring map # multipath -l mpatho (360060160bf902a0078177a31e4b4e311) dm-2 3PARdata,VV size=100G features='0' hwhandler='0' wp=rw `-+- policy='round-robin 0' prio=0 status=active |- 2:0:0:70 sdb 8:16 active undef running `- 2:0:1:70 sde 8:64 active undef running mpathj (360060160bf902a0098bf9953e4b4e311) dm-3 3PARdata,VV size=1.
8 Performing MDM Using a Hyper-V Host The MDM process is used when migrating a Hyper-V host with a source EMC Storage system. The host DSM must be updated to communicate with the destination HP 3PAR StoreServ Storage system, and the host must be shutdown briefly. Host I/O is interrupted only during the time it takes to reconfigure the host. Required Information Source storage system: • WWN of the source EMC Storage system from which LUNs are being migrated.
1. From the HP 3PAR Online Import Utility, execute the createmigration command. Example 41 createmigration command >createmigration -sourceuid 50067890C6E059EE -srchost "HPDL585-01" -destcpg "FC_r5" -destprov thin -migtype MDM >SUCCESS: Migration job submitted successfully. Please check status/details using showmigration command. Migration id: 1395864499741 NOTE: Be aware, the createmigration command may take several minutes to complete.
NOTE: After removal, you will be prompted to restart the host in order for the changes to take effect. Do not restart at this point. 2. 3. 4. 5. The removal of EMC PowerPath Multipath software might have also disabled the MPIO installation, but not removed it. Manually check to see whether MPIO is still loaded, and if it is, fully remove it at this time. Now restart the host.
TIP: The final status on successful completion will indicate “success”. Bringing the Hyper-V Host Back Online To bring the Hyper-V Host back online, follow these steps: 1. Verify that the import has started and confirm that a TASK_ID is available for each volume by issuing the showmigrationdetails command.
Performing Subsequent Migrations The source EMC Storage system and destination HP 3PAR StoreServ Storage system that have been defined using the HP 3PAR Online Import Utility addsource/adddestination commands, can remain defined for subsequent migrations. You only need to run the HP 3PAR Online Import Utility addsource and adddestination commands if a subsequent migration will be using a new source or destination storage system.

Historic data from source volumes is moved to destination volume over peer port. Once the data transfer is complete, export to the source host will be executed if the data migration type is MDM. At the source storage system, the presentation of the source volume to the source host will be removed. If possible, the source volume will be locked but not deleted.
12 Troubleshooting This section describes problems you may encounter when using EMC Storage-to-HP 3PAR StoreServ Storage 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.
HP 3PAR Online Import Utility Service The HP 3PAR Online Import Utility 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. HP 3PAR Online Import Utility Server Logs and Output When an issue occurs, get all the HP 3PAR Online Import Utility server logs and output to assist with troubleshooting.
EMC SMI-S Provider Server Logs and Output When an issue occurs, get all the EMC SMI-S Provider server logs and output to assist with troubleshooting. Use the following action and commands to get the logs and output.
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 the EMC SMI-S Provider server. Log into the EMC 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.

HP 3PAR Online Import Utility for EMC Storage Error Messages OIUERRSRC0020 = "Unsupported EMC storage system version "; OIURSLSRC0020 = "Check support matrix and upgrade EMC."; Problem: Source EMC Storage system version check failed. Solution: Source EMC Storage system must be running at supported version. OIUERRSRC0111 = "Unable to present the volume to the host in EMC array"; OIURSLSRC0111 = "Contact HP Support if the problem persists.
Problem: There could be a problem with communication or access. Solution: Logs will show the exact cause as an exception trace. Configuration (remote IP access, local access) of the ECOM might need to be rectified. OIUERRAPP0011 = "EMC Provider WBEM Connection, Malformed URL."; OIURSLAPP0011 = "Application internal error, see Log file for details. Contact HP Support." Problem: This would indicate a defect in accessing the provider due to incorrect protocol (HTTP, HTTPS allowed), or no protocol at all.
Not able to create migration Possible causes: • Duplicate volumes exist. This may occur if either a virtual volume with same name or with the same WWN exists on the destination storage system. • A host on the destination storage system has a duplicate name. • The destination storage system does not have enough capacity. • EMC SMI-S Provider is running an unsupported software version. • EMC SMI-S Provider user name/password have changed since source storage system was added.
Migrated LUNs with No Host in a Storage Group Failed OIU:createmigration Solution: If migrated LUNs do not have an associated host, the migration type must be offline. OIU:createmigration Error for LUN Name or Host Name Containing Special Characters Solution: The HP 3PAR Online Import Utility does not support special characters in the LUN name or host name and will cause an error on the createmigration command if special characters are present in the names.
HP 3PAR Online Import Utility createmigration Results in “preparationfailed(-NA-)(OIUERRPREP1014: Error creating host on destination)” Problem: Host already exists on destination HP 3PAR StoreServ Storage system with a different WWN. Solution: If the same host but different WWN: On initial migration of a host, all WWNs to be included in storage group (even if not managing any LUNs). This way subsequent migration of any WWN for this host will find a match.
An “unexpected error” message when destprov/destcpg are not specified for all LUNs Problem: ERROR: OIUERRAPP0000 on createmigration using srcvolmap. This is an example of the error: >createmigration -sourceuid 50060160C6E0167A -srcvolmap [{"temp_1", thin, "FC_r6"}] -migtype MDM >ERROR: OIUERRAPP0000 An unexpected error occured. OIURSLAPP0000 Contact HP support. You may try restarting the application service.
Scope: This may be experienced when an adddestination –type 3PAR command is issued with the –secure=true and –port flags included. Solution: If the above error occurs, the HP-3PAR-MC-TrustStore keystore file must be created or modified in the \InformMC\Security folder and copied into the folder as shown in the error message, such as C:\InformMC\Security in the above example.
Example 68 Error message—example 2 Time : 2014-07-24 07:41:32 EDT Severity : Minor Type : CLI command error Message : {3paradm super all {{0 8}} -1 15.234.144.106 27814} {Command: admitvv EMC_1:XXXXXXXXXXXXXXXXXX Error: Volume XXXXXXXXXXXXXXXXXXXX was not admitted--0 VVs admitted.
Restarted Migration Showed Incorrect FAILED Status Problem: If a migration failed and it has been restarted using the HP 3PAR Online Import Utility startmigration command again, the status will immediately change to IMPORTING. However, due to timing issues, the status may change back to FAILED for a short time before returning to IMPORTING.
