2 Migration Process Checklists

Follow the steps in this chapter to perform online migration, MDM, or offline migration.

Online Migration

Prerequisite Component Installation

Table 1 Prerequisite component installation—Online

Number Step

1Check the HP SPOCK website to confirm proper configuration.

See

HP SPOCK (http://www.hp.com/storage/spock)

See also “Configuration Rules for HP 3PAR Online Import for EMC Storage Support” (page 15)

2	Install EMC SMI-S Provider.	“Installing EMC SMI-S Provider” (page 15)
3	Install the HP 3PAR Online Import Utility.	“Installing the HP 3PAR Online Import Utility for
		EMC Storage” (page 17)

Premigration

If EMC PowerPath is installed, it must be uninstalled, and device-mapper must be used to configure multipathing; see the third column in the Table 2 (page 9) for details about each step. If EMC PowerPath is not installed, see the column on the right for details.

Table 2 Premigration checklist—Online

Number Step

1Zone EMC Storage systems and HP 3PAR StoreServ Storage systems as peers.

2Add source storage system (HP 3PAR Online Import Utility: addsource command).

3Add destination storage system (HP 3PAR Online Import Utility: adddestination command).

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

5Configure device-mapper on the host.

If EMC PowerPath is installed, see:

“Online Data Migration with Removal of EMC PowerPath” (page 40), step 1

“Online Data Migration with Removal of EMC PowerPath” (page 40), step 2

“Online Data Migration with Removal of EMC PowerPath” (page 40), step 3

“Online Data Migration with Removal of EMC PowerPath” (page 40), step 4

1.Uninstall EMC PowerPath:
