CAUTION:
If you specify a volume with a larger capacity than the migration source volume for the migration
target volume, the migration target volume is deleted prior to migration, and then created again
with the same capacity as the migration source volume. Therefore, the migration task will require
more time than when migrating to a volume of the same capacity.
If the migration target volume is re-created, the free capacity of the parity group increases by the
difference in capacity with the migration source volume. For example, if a volume that has 30 GB
is specified as a migration target for a migration source volume that has 10 GB, the free capacity
of the parity group increases by 20 GB. Therefore, we recommend that you specify, as a migration
target, a volume that is as close in capacity to the migration source volume as possible.
migration.multiExecution
Specify the number of migration pairs that can be executed simultaneously in a storage system.
The range for specifiable values is from 1 to 64.
Default: 8
Properties for connecting to PA (hppa.properties file)

hppa.properties
In Linux:
installation-directory-for-the-Device-Manager-server/Server/config/
hppa.properties
hppa.infoAcquirePeriod
Specify the period for which performance information, such as the parity group usage rate and the
volume IOPS, is collected and summarized.
The following three time periods can be specified:
day: Collects and summarizes performance information on a daily basis.
week: Collects and summarizes performance information on a weekly basis. In PA, a week is
from Monday to Sunday.
month: Collects and summarizes performance information on a monthly basis. In PA, a month is
from the first day to the last day of the month.
The information displayed is the performance information from when summarization was last completed.
As such, if day is specified, performance information from the previous day is displayed, if week is
specified, from the previous week, and if month is specified, from the previous month. Even if you
refresh the storage system during the week or the month, the same information is displayed.
Default: day
