Description
The name of an Enhanced Global Mirror Group
repository volume for which you want to increase the
capacity.
The name of a repository volume is comprised of two
parts:
v The term repos
v A four digit numerical identifier that the storage
management software assigns to the repository volume
name
Enclose the name of the repository volume in double
quotation marks (" ").
The name of an unused repository volume that you want
to use to increase the capacity of another repository
volume. An available standard volume is added to the
repository volume to increase the capacity of the
repository volume.
The name of the unused repository volume is comprised
of two parts:
v The term repos
v A four digit numerical identifier that the storage
management software assigns to the repository volume
name
Enclose the name of the existing repository volume in
double quotation marks (" ").
You can enter more than one repository volume name.
Enclose each repository volume name in double
quotation marks (" ") inside parenthesizes (( )). Separate
each repository volume name with a white space.
Use this parameter to promote the Enhanced Global
Mirror Group to a primary role or demote the Enhanced
Global Mirror Group to a secondary role. To define the
Enhanced Global Mirror Group as the primary role, set
this parameter to primary. To define the Enhanced
Global Mirror Group as the secondary role, set this
parameter to secondary.
The role reversal is forced if the communications link
between the storage subsystems 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.
This parameter defines whether to perform an initial
synchronization between the primary storage subsystem
and the secondary storage subsystem before a role
reversal operation is performed. To perform an initial
synchronization, set this parameter to TRUE. The default
value is FALSE.
