Use the mkfcconsistgrp command to create
a new FlashCopy consistency
group and identification name.
Syntax
mkfcconsistgrp [ -name consist_group_name ] [ -autodelete ]
Parameters
- -nameconsist_group_name
- (Optional) Specifies a name for the consistency group. If you
do not specify a consistency group name, a name is automatically assigned
to the consistency group. For example, if the next available consistency
group ID is id=2, the consistency group name is fccstgrp2.
Note: Consistency group names must be an alphanumeric string
of up to 15 characters.
- -autodelete
- (Optional) Deletes the consistency group when the last mapping
that it contains is deleted or removed from the consistency group.
Description
This
command creates a new consistency group and identification name. The
ID of the new group is displayed when the command process completes.
If
you have created several FlashCopy mappings
for a group of volumes that contain elements of data for the same
application, you might find it convenient to assign these mappings
to a single FlashCopy consistency
group. You can then issue a single prepare command and a single start
command for the whole group, for example, so that all of the files
for a particular database are copied at the same time.
Note: Maps that are rc_controlled are
not shown in the view when this command is specified.
Remember: Names representing Metro Mirror
or Global Mirror consistency groups relationships are restricted to
fifteen characters in length (not sixty-three for an extended character
set).
An invocation example
