In this example, there are four Object storage groups, two primary volumes (A and B), and two backup volumes (C and D) as shown in Figure 1.
Figure 1. Object Storage Group and Volume Relationship
You can concurrently start the Move Volume utility in
the following situations:
- A and D or B and D—A primary source volume and a backup source volume where the primary volumes containing the objects are in different Object storage groups. The Move Volume utility for primary source volume A only accesses objects in Object storage group 1, and the Move Volume utility for backup source volume D only accesses objects in Object storage groups 3 and 4.
The Move Volume utility should not be started concurrently
for the following situations:
- A and B—Two primary source volumes in the same Object storage group. This scenario concurrently accesses objects in Object storage group 1 during the two Move Volume utilities processing primary source volumes A and B.
- A and C or B and C—A primary source volume and a backup source volume where the primary volumes containing the objects are in the same Object storage group. This scenario concurrently accesses objects in Object storage group 1 during the two Move Volume utilities processing primary source volume A and backup source volume C.
- C and D—Two backup source volumes where the primary volumes containing the objects are in the same Object storage group. This scenario concurrently accesses objects in Object storage group 3 during the two Move Volume utilities processing backup source volumes C and D.
