Description
The name of the Enhanced Global Mirror Group that you
want to modify. Enclose the Enhanced Global Mirror
Group name in square brackets ([ ]). If the Enhanced
Global Mirror Group name has special characters, you
also must enclose the name in double quotation marks ("
") inside square brackets. If the Enhanced Global Mirror
Group name consists only of numbers, such as "1002,"
you also must enclose the name in double quotation
marks (" ") inside square brackets.
Specify the length of time between automatically sending
updates of modified data from the local storage
subsystem to the remote storage subsystem. You can
specify the length of time in minutes, hours, or days.
Specify the length of time to wait until a warning is
triggered for cases in which the synchronization of all of
the volumes within the Enhanced Global Mirror Group
takes longer than the defined time. You can specify the
length of time in minutes, hours, or days.
Specify the length of time to wait until a warning is
triggered when the automatic data update for the
point-in-time image on the remote storage subsystem is
older than the defined time. Define the threshold from
the end of the previous update. You can specify the
length of time in minutes, hours, or days.
NOTE You must set the Recovery Point Threshold to be
twice as large as the synchronization interval threshold.
Specify the percent value that determines when a
warning is triggered when the capacity of a mirror
repository volume reaches the defined percentage. Define
the threshold by percentage (%) of the capacity
remaining.
The new name that you want to give to the Enhanced
Global Mirror Group. Use this parameter when you want
to rename the Enhanced Global Mirror Group. Enclose
the new Enhanced Global Mirror Group name in double
quotation marks (" ").
The settings for automatic resynchronization between the
primary volumes and the secondary volumes of an
Enhanced Global Mirrored pair within an Enhanced
Global Mirror Group. 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.
disabled– Automatic resynchronization is turned off.
v
To resynchronize the primary volume and the
secondary volume, you must run the resume
enhancedGlobalMirrorGroup command.
