The Data Migration wizard enables you to configure multiple jobs in a batch mode.
The jobs configured in batch mode have the same common attributes. For more
details, see “Using the Data Migration Wizard” on page 3-7.
Data Migration Job States
Table 1-1 lists the possible data migration job states.
Data Migration Job CLI Commands
DMS provides CLI commands (migration stop/start/pause/resume) to
alter the state of the migration job. The migration stop/start command
causes a job to be stopped and then restarted from the beginning. The
migration stop command rewinds the job to the beginning.
You can use the migration pause/resume commands only on running jobs.
The migration pause command causes the job to halt temporarily. The
migration resume command causes the job to resume from the point where it
was paused; it will not start from the beginning of the LUN. Pause a migration job
if it is taking a lot of array bandwidth and causing other processes on the array to
slow down. You can later resume the job when the I/O activity on the array is
reduced.
Table 1-1. Data Migration Job States
Job State Description
Running Job is currently running. You can pause or stop a running job.
Scheduled Job is waiting to be run.
Completed Job is complete. You must acknowledge a completed job.
Paused A running job has been interrupted.
Stopped A running, scheduled, failed, or pending job has been halted. You can
restart or remove a job in the Stopped state.
Failed
The
MPX200 lost access to the LUN during a data migration job, caus-
ing it to fail.
Pending A job configured for a delayed start (either due to Delayed Scheduling
or Serial Scheduling) cannot start at the specified time because the
source or destination LUN is offline. When the LUN becomes online,
the job will go into the Running state. If you determine that the specified
LUN will never come back online, you can remove the pending job.
