mkfcconsistgrp

Use the mkfcconsistgrp command to create a new FlashCopy consistency group and identification name.

Syntax

mkfcconsistgrp [ -nameconsist_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).
