Parameters
Parameter
Description
localVolume
or
localVolumes
The name of the primary volume for which you want to
define properties. You can enter more than one primary
volume name. Enclose the primary volume name in
square brackets ([ ]). If the primary volume name has
special characters, you also must enclose the primary
volume name in double quotation marks (" ").
role
The setting for the volume to act as the primary volume
or the secondary volume. To define the volume as the
primary volume, set this parameter to
primary
. To define
the volume as the secondary volume, set this parameter
to
secondary
. This parameter applies only when the
volume is part of a mirror relationship.
force
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
.
syncPriority
The priority that full synchronization has relative to host
I/O activity. Valid values are
highest, high, medium,
low,
or
lowest.
autoResync
The settings for automatic resynchronization between the
primary volumes and the secondary volumes of a
remote-mirrored pair. This parameter has these values:
v
enabled
– Automatic resynchronization is turned on.
You do not need to do anything further to
resynchronize the primary volume and the secondary
volume.
v
disabled
– Automatic resynchronization is turned off.
To resynchronize the primary volumes and the
secondary volume, you must run the
resume
syncMirror
command.
writeOrder
This parameter defines write order for data transmission
between the primary volume and the secondary volume.
Valid values are
preserved
or
notPreserved
.
writeMode
This parameter defines how the primary volume writes
to the secondary volume. Valid values are
synchronous
or
asynchronous
.
Notes
When you use this command, you can specify one or more of the optional parameters. Synchronization
priority defines the amount of system resources that are used to synchronize the data between the
primary volumes and the secondary volumes of a mirror relationship. If you select the highest priority
level, the data synchronization uses the most system resources to perform the full synchronization, which
decreases the performance for host data transfers.
