Scheduling Data Migration Jobs in Batch Mode
Batch mode for data migration jobs is an HP StorageWorks mpx Manager
GUI-only feature used to schedule multiple jobs having the same priority, I/O size,
and group options.
This option is particularly useful for migration jobs specified as Schedule for later
and Serial Schedule Jobs on the Data Migration Jobs Options dialog box, where
the jobs need to be classified under a specific group for better management.
DMS allows a maximum of eight jobs to run simultaneously at any specific time
per source array. To optimize MPX200 performance, QLogic recommends that
you run simultaneously no more than four jobs on any specified source or
destination array.
Consider a data center having multiple applications running on multiple storage
arrays that need to be consolidated, and data migration needs to be done on
associated LUNs. The data migration administrator must plan the data migration
operation to minimize the application downtime. In order to achieve this, the HP
StorageWorks mpx Manager provides an option to create data migration job
groups, as described in “Creating a Data Migration Job Group” on page 3-6.
You can combine all the source LUNs associated with a specific application into a
single job group and schedule it for migration using the Schedule in batch mode
option. That way all the jobs can start at a predefined time, which can be off-peak
hours when the administrator can afford a small application downtime.
Follow these steps to schedule a batch of data migration jobs.
To schedule data migration jobs in batch mode:
1. Start the Data Migration wizard by following the steps specified in “Starting
the Data Migration Wizard” on page 3-7.
2. In the Migration Schedule Options dialog box, click Schedule in batch
mode, and then click OK. (See Figure 3-6.)
