Dell POWERVAULT MD3600I - Manual (Page 133)

– 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.
8. Select View advanced options and then accept or change the following default settings as appropriate.
For more information on the advanced settings, see the online help topics.
9. Click Finish.
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.
3. Type a new name for the consistency group and then click Rename.
Deleting A Consistency Group
Use the Delete Consistency Group option to delete a consistency group.
The system deletes the following when a consistency group is deleted:
• All existing snapshot images from the consistency group.
• All existing snapshot virtual disks from the consistency group.
• All the associated snapshot images that exist for each member virtual disk in the consistency group.
• All the associated snapshot virtual disks that exist for each member virtual disk in the consistency group.
• All associated repositories that exist for each member virtual disk in the consistency group (if selected).
