4 Data Migration commands

Data migration is a block-level, online and offline feature introduced in the MPX200 data transport

device. The HP StorageWorks MPX Manager utility provides this optional, licensed feature to

simplify data migration jobs for almost zero downtime, while providing protection against common

user errors.

Before you use data migration commands, ensure that:

• The router is running firmware version 3.2.3.0 or later.

• The router is capable of performing data migration.

• You have installed an appropriate data migration license.

To view the router capabilities and licensing status, issue the show features command. See

“show features” (page 68).

This chapter provides the description, syntax, and examples of each of the data migration commands

available in the Remote CLI. The commands are listed in alphabetic order. All examples shown in

this chapter are shown from a Microsoft Windows command prompt, but the output is also

applicable to Linux systems.

NOTE: Keywords that apply to all commands are not listed in this chapter. The general keywords

described in “General keywords” (page 12) are optional for every command in this chapter.

(page 108)

acknowledge migration

The acknowledge migration command removes a completed data migration job from the

router. You must acknowledge jobs to free up the destination LUN before it can become part of

another job.

For an online migration job, the DRLs are flushed to the destination LUN before removing the job.

You must ensure that host access to the source LUN has been terminated before issuing the

acknowledge migration command.

TIP: To remove jobs that have not yet completed, use the remove migration command.

Syntax

acknowledge migration -dm_jobid=data migration job ID

Example

c:\> rcli acknowledge migration -dm_jobid=0 /ip=10.0.0.12

[10.0.0.12]

Data Migration job 0 removed successfully

add dm_group

The add dm_group command adds a data migration job group.

Syntax

add dm_group -name=data migration job group name
