Q. Can I
control the order in which Genesis migrates data?
A.
Yes. There are a number of parameters governing
migration order, for example, by Storage Group, By Age
of Data, etc. In addition you can hold or exclude data
from the migration process (so you can hold or exclude
an entire Application for example). |
Q. Why would
I want to control the order of migration?
A. The data
that is being converted is generally still 'active', so
the conversion strategy needs to avoid contention with
Production activities. |
Q. Can
I control how much conversion work Genesis does each day
to fit around known production workloads?
A. Yes.
Genesis can be tuned via parameters held in DB2 which
control exactly how much conversion work is done, when,
to fit in around your exiting workloads. ICS can work
with you to find windows within your daily, weekly and
monthly schedules. |
Q. Once the
data is selected, how does Genesis optimize migration?
A. Genesis sorts migration requests into an order
where each platter is only visited once and avoids
platter flips. Without this, experience shows that media
mount/flip time can significantly reduce throughput
(Excessive flipping is also a common cause of media
failure). |
Q. Do I have
to set-up the workload for Genesis every day?
A. No.
Genesis includes a processing calendar which allows
you to set up the entire conversion in advance. |
Q. Do I have
to monitor what Genesis is doing every day?
A. No.
Genesis will alert you by email if the scheduled
migrations fail. Detailed logs supply information about
the specific issues. |
Q. Some of
our OAM data has been around a long time, what if there
are data integrity issues with it?
A. Genesis can be
set up to fail anytime an error is found, or continue up
to a failure limit - allowing it to continue processing
if it hits some bad data. Genesis outputs detailed logs
when it hits a problem, allowing for follow up. Bad
data can then be excluded from the conversion. Genesis
allows for individual files to be excluded, ranges of
files, right up to entire collections or entire
applications.
|
Q. If Genesis
hits a problem, can it be restarted?
A. Yes. Genesis
has full checkpoint/restart capability. |
