Figure 39 Migrating data and replacing the original primary array (R1)
Replacing R1 and R2 devices with new R1 and R2 devices
You can use the combination of concurrent SRDF and cascaded SRDF to replace both
R1 and R2 devices at the same time.
Before you begin, verify that your specific hardware models and Enginuity or
HYPERMAX OS versions are supported for migrating data between different
platforms.
The following image shows an example of replacing both R1 and R2 devices with new
R1 and R2 devices at the same time, including:
