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).

Online Data Migration with Removal of EMC PowerPath

To perform online data migration using RHEL 5.x or RHEL 6.x, follow these steps.

NOTE: A maintenance window is required to complete an online data migration with removal of EMC PowerPath (see step 5).

1.Zone the source array to the destination array.

2.Using the HP 3PAR Online Import Utility addsource command, add the source storage system

Example 7 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

10.10.10.10Good

3.Using the HP 3PAR Online Import Utility adddestination command, add the destination HP 3PAR StoreServ Storage system.

Example 8 Using adddestination to add the destination storage system for online data migration

>adddestination -type 3PAR -mgmtip 10.10.10.10 -user 3paradm -password 3parpassword >SUCCESS: Added destination storage system.

4.Zone the host to the HP 3PAR StoreServ Storage system.

5.Uninstall EMC PowerPath by following these steps:

CAUTION: EMC PowerPath must not be installed during the migration process. Native device-mapper-multipath must be managing the paths.

Stop all applications before removing EMC PowerPath. For cluster configurations, also stop the cluster services and the cluster. Applications should be restarted after migration has started.

NOTE: A maintenance window is required. This step requires that all applications be stopped, but a reboot is not required.
