Creating the Data Migration Task

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 10.10.10.10 –user 3paradm –password 2Password >SUCCESS: Added destination storage system

If a certificate validation error occurs on the adddestination command when using the -secure=true parameter (see Example 4 “Certificate validation error”), first run the installcertificate command (see Example 5 “Installcertificate command”), then run the adddestination command again.

Example 4 Certificate validation error

>adddestination -type 3PAR -mgmtip xx.x.xx.xx -user 3paradm -password 3pardata -secure true -port 5783

>ERROR: OIUERRDST0010 Unable to validate certificate. C:\\InFormMC\security\HP-3PAR-MC-TrustStore

Example 5 Installcertificate command

>installcertificate –mgmtip xx.xx.xx.xx

TParCertifacteVO [issuedTo=HP 3PAR HP_3PAR 7400 1645897, commonName=null, issuedByOrganization=null, issuedToOrganization=null, serialNo=null, issedBy=HP 3PAR HP_3PAR 7400 1645897, fingerprint=89:E5:D0:13:6F:D1:07:80:70:76:5C:FE:5B:65:E5:54:C0:18:21:2F, signatureAlgo=SHA1withRSA, version=v1,validFrom=08/14/2014, validTo=08/11/2024. issuedOn=null, expiresOn=null, validDateRange=true] Do you accept the certificate? Y/YES Y

>SUCCESS: Installed certificate successfully.

2.Execute the showdestination command to verify the destination storage system information.

Example 6 showdestination command

>showdestination

The data migration task performs the following actions in the preparation required for data migration:

•On a VNX or CLARiiON CX4 source storage system, two HP 3PAR initiators are added to the storage group that contains the hosts or volumes being migrated. The host name of the HP 3PAR initiators is unknown. The initiator name appears as the WWN of the peer port on the HP 3PAR StoreServ Storage.

•On a VMAX source storage system, the following groups are created for the migration:

◦

One storage group is added, containing the devices being migrated. The naming convention is:

OIU_<migrationID>_SG

One initiator group per HP 3PAR peer port is added. The naming convention is:

<hostname>_<migrationID>
