6. Select the repository, from the Repository candidates table, that you want to use for each member
virtual disk in the consistency group.
NOTE: Select a repository candidate that is closest to the capacity you specified.
– The Repository candidates table shows both new and existing repositories that are capable of
being used for each member virtual disk in the consistency group based on the value you
specified for percentage or the value you specified for preferred capacity.
– By default, the system displays the repositories for each member virtual disk of the consistency
group using a value of 20% of the member virtual disk’s capacity. It filters out undersized
repository candidates, and those with different Data Service (DS) attributes. If appropriate
candidates are not returned using these settings, you can click Run Auto-Choose to provide
automatic candidate recommendations.
– The Difference column shows the mathematical difference between your selected capacity and
the actual capacity of the repository candidate. If the repository candidate is new, the system uses
the exact capacity size that you specified and displays zero (0) in the Difference column.
7. To edit an individual repository candidate:
a) Select the candidate from the Repository candidates table and click Edit to modify the capacity
settings for the repository.
b) Click OK.

Renaming A Consistency Group
Use the Rename Consistency Group option to change the name of the consistency group when the
current name is no longer meaningful or applicable.
Keep these guidelines in mind when you name a consistency group:
• A name can consist of letters, numbers, and the special characters underscore (_), hyphen (-), and
pound (#). If you choose any other characters, an error message is displayed. You are prompted to
choose another name.
• Limit the name to 30 characters. Any leading and trailing spaces in the name are deleted.
• Use a unique, meaningful name that is easy to understand and remember.
• Avoid arbitrary names or names that would quickly lose their meaning in the future.
• If you try to rename a consistency group with a name that is already in use by another consistency
group, an error message is displayed, and you are prompted to choose another name for the group.
To rename a consistency group:
1. From the AMW, select the Storage & Copy Services tab.
2. Select the consistency group that you want to rename and then select Copy Services → Consistency
Group → Rename.
The Rename Consistency Group window is displayed.
