Migration

Table 7 Migration checklist—MDM

Number Step

1Start the migration (HP 3PAR Online Import Utility: startmigration command)

See

For Windows:

“Starting the Data Migration from Source EMC Storage System to Destination HP 3PAR StoreServ Storage System” (page 54)

For Linux:

“Starting the Data Migration from Source EMC Storage System to Destination HP 3PAR StoreServ Storage System” (page 58)

For Hyper-V:

“Starting the Data Migration from Source EMC Storage System to Destination HP 3PAR StoreServ Storage System” (page 63)

2Restart the host and rescan migrating disks. Restart server applications (including cluster).

For Windows:

“Bringing the Windows Host Back Online” (page 54)

For Linux:

“Bringing the Linux Host Back Online” (page 59)

For Hyper-V:

the migration has completed.

 

Post-Migration

Table 8 Post-migration checklist—MDM

Number Step

1Remove zoning between the EMC Storage system and HP 3PAR StoreServ Storage system after all migrations from the EMC Storage system are complete.

2

When all migrations are complete, remove the source storage system (EMC).

3Remove peer zones and reconfigure peer ports to host ports.
