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

>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.

TIP: Make a note of the Migration ID as it will be used in commands to track migration progress.

2.Execute the showmigration command to verify that the data migration task preparation has completed successfully. This may take some time. On the successful creation of the task the STATUS column will indicate preparationcomplete(100%).

Example 33 showmigration command

>showmigration -migrationid 1395864499741

Perform the following steps on the Linux host:

1.Remove EMC PowerPath Multipath software from the host by following these steps:

a.Close all applications on the host.

b.For a cluster, stop the cluster services, and then stop the cluster.
