CLI Guide

Parameter Description
define the remote replication group as the primary
role, set this parameter to primary. To define the
remote replication group as the secondary role, set
this parameter to secondary.
force
The role reversal is forced if the communications
link between the storage arrays is down and
promotion or demotion on the local side results in
a dual-primary condition or a dual-secondary
condition. To force a role reversal, set this
parameter to TRUE. The default value is FALSE.
NOTE: Use the force parameter only when
using the role parameter.
nosync
This parameter defines whether to perform an
initial synchronization between the primary remote
replication group and the secondary remote
replication group before a role reversal operation is
performed. To perform an initial synchronization,
set this parameter to TRUE. The default value is
FALSE.
Notes
You can use any combination of alphanumeric characters, underscore (_), hyphen (-), and pound (#) for
the names. Names can have a maximum of 30 characters.
When you use this command, you can specify one or more of the parameters. You do not, however,
need to use all of the parameters.
A remote replication group repository virtual disk is an expandable virtual disk that is structured as a
concatenated collection of up to 16 standard virtual disk entities. Initially, an expandable repository virtual
disk has only a single element. The capacity of the expandable repository virtual disk is exactly that of the
single element. You can increase the capacity of an expandable repository virtual disk by attaching
additional standard virtual disks to it. The composite expandable repository virtual disk capacity then
becomes the sum of the capacities of all of the concatenated standard virtual disks.
A remote replication group repository virtual disk must satisfy a minimum capacity requirement that is the
sum of the following:
• 32 MB to support fixed overhead for the remote replication group and for copy-on-write processing.
• Capacity for rollback processing, which is 1/5000th of the capacity of the base virtual disk.
The minimum capacity is enforced by the RAID controller module firmware and the MD storage
management software.
