Parameter

Description

name of either a a disk group or a disk pool in

which you want the repository virtual disk.
Optionally, you also can define the capacity of the

repository virtual disk. If you want to define the

capacity you can use these values:

• An integer value that represents a percentage

of the base virtual disk capacity.

• A decimal fraction value that represents a

percentage of the base virtual disk capacity.

• A specific size for the repository virtual disk.

Size is defined in units of bytes, KB, MB, GB, or

TB.

If you do not use the capacity option, the MD

storage management software sets the capacity to

20 percent of the base virtual disk capacity.
Enclose the name of the new repository virtual disk

in parenthesis ( ).

role

Use this parameter to promote the remote
replication group to a primary role or demote the
remote replication group to a secondary role. To
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.

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
