Notes
You can use any combination of alphanumeric characters, hyphens, and underscores for the names.
Names can have a maximum of 30 characters.
Copy priority defines the amount of system resources that are used to copy the data between the source
logical drive and the target logical drive of a VolumeCopy pair. If you select the highest priority level, the
VolumeCopy uses the most system resources to perform VolumeCopy, which decreases performance for
host data transfers.

Deactivate Remote Mirror

This command deactivates the Enhanced Remote Mirroring feature, disassembles the mirror repository
logical drive, and releases the controller-owner of the secondary logical drive. The controller host port
that is dedicated to the secondary logical drive is available for host data transfers.
Description
Use this parameter to create a VolumeCopy with a
FlashCopy . Creating a VolumeCopy with a FlashCopy
enables you to continue to write to the source logical
drive while creating the VolumeCopy. To create a
VolumeCopy with a FlashCopy, set this parameter to
online. To create a VolumeCopy without a FlashCopy,
set this parameter to offline.
If you do not use this parameter, the VolumeCopy is
created without a FlashCopy .
This parameter determines the size of the repository
logical drive for the FlashCopy when you are creating a
VolumeCopy with a FlashCopy . The size of the
repository logical drive is expressed as a percentage of
the source logical drive, which is also called the base
logical drive. Valid values for this parameter are 20, 40,
60, 120, and default. The default value is 20. If you do
not use this parameter, the firmware uses a value of 20
percent.
This parameter determines to which subsystem the
FlashCopy repository logical drive is written. You have
these choices:
v sameAsSource – The FlashCopy repository logical
drive is written to the same subsystem as the source
logical drive if space is available.
v otherThanSource – The FlashCopy repository logical
drive is written to a different subsystem. Firmware
determines which subsystem based on available
space on the subsystems.
v default – The FlashCopy repository logical drive is
written to any subsystem that has space.
For best performance, use the sameAsSource option.
You must use the copyType parameter with the
repositoryGroupPreference parameter.
