Data scrubbing logs
Data scrubbing jobs generate logs for every user configuration event, as well as for job STARTING,
FAILING or COMPLETION. You can view data scrubbing logs using the same interface as used
for migration logs, see
“Viewing system and data migration job logs” (page 63) .
Data scrubbing licenses
Data scrubbing license keys are based on an MPX200 blade serial number. The licenses are
shared between two blades in the same MPX200 chassis. The two data-scrubbing license types
are:
•
Capacity-based licenses
•
Array-based licenses
NOTE: Data scrubbing jobs up to 5 GB currently do not require a license.
Protection
DMS provides data protection against some of the common user errors by enforcing the following
restrictions:
•
An array must have an attribute of either Source, Destination, or Source+Destination to
participate in the migration. When you configure a data migration job, Source LUNs can be
assigned only from an array with the attribute Source (or Source+Destination), and Destination
LUNs can be assigned only from an array with the attribute Destination (or Source+Destination).
Use these attributes properly to avoid errors.
•
A user acknowledgement is required for a data migration job after the job is completed. This
feature provides better accounting and record-keeping for the job. The data migration log
indicates when the job was completed and when you acknowledged the completion status of
the job.
•
For online or offline data migration, after a LUN is configured as a destination LUN for a
specific data migration job, the LUN cannot be configured for a different job until the current
job is acknowledged or removed.
•
DMS detects the normal configuration of Windows OS partitions on the data LUN. Before
fully configuring a data migration job, DMS provides a warning if it detects valid partition
tables on the destination LUN.
Logs
DMS manages the following two log types:
•
Migration logs: Migration logs provide a detailed history of each data migration job. The job
history contains information such as the start and end time of the job, source and destination
LUNs and arrays, size of the job, total time consumed for the job, and so on. Using HP mpx
Manager, you can export the migration logs out of the MPX200. You can open this file with
a spreadsheet application such as Microsoft Excel and use it as a data migration task report.
HP highly recommends that you save migration logs after the data migration job is completed
and cleared from the MPX200. This task provides a record of every data migration job and
makes it easier to differentiate between them.
•
System logs: System logs primarily record events, errors, and configuration changes, and can
be used for troubleshooting.
