In the above image, under Replication Volumes for the P9000 disk array 53036:
• Business Copy Volumes is a component type. The number (15) indicates the number of LDEVs that
are assigned as business copy volumes. Click Business Copy Volumes to view the list of LDEVs.
• Continuous Access Volumes is a component type. The number (15) indicates the total number of
journal pools that are created.
• JID-0:0 is a journal pool under which LDEVs is a component type. The number (1) indicates
the number of LDEVs assigned to the JID-0:0.
• 1:3C is an LDEV assigned to the JID-0:0.
For the LDEVs that are configured as the business copy and the continuous access volumes, the
associated RAID groups can also be traced under the Back-end category. For more information, see
“Back-end navigation path” on page 278.
The related metrics associated with the resources types and components in the Replication Volumes
