Figure 2-15 Striped and Sequential volumes
򐂰 Image mode
Image mode volumes are special volumes that have a direct relationship with one MDisk.
They are used to migrate existing data into and out of the IBM Flex System V7000 Storage
Node.
When the image mode volume is created, a direct mapping is made between extents that
are on the MDisk and the extents that are on the volume. The logical block address (LBA)
x on the MDisk is the same as the LBA x on the volume, which ensures that the data on
the MDisk is preserved as it is brought into the clustered system (Figure 2-16 on page 66).
