Figure 2 Structure of cascaded pairs
•
The P-VOL of the L1 pair is the “root volume”.
•
An S-VOL of the L1 pair is a “node volume”.
•
A P-VOL of an L2 pair is an L1 S-VOL — a node volume.
•
An S-VOL of an L2 pair is a “leaf volume”.
Business Copy cascaded pairs may be used as Continuous Access Synchronous pairs. No distinction
is made in Continuous Access Synchronous between node and leaf volumes. Both are considered
as S-VOLs.
Remote Web Console GUI
With the Remote Web Console GUI, you enable the Business Copy license key, configure the
storage system, perform copy operations, and perform monitoring, maintenance, and
troubleshooting.
The Remote Web Console GUI communicates with the storage system’s service processor (SVP)
over defined TCP/IP connections. Remote Web Console is LAN-attached to the storage system.
RAID Manager and consistency groups
With RAID Manager you use a command line interface for running most of the same operations
as are performed with Remote Web Console. Pair commands are issued directly from the host.
Commands can also be automated using scripts.
Using RAID Manager, you can specify multiple pairs as a consistency group. With a consistency
group, operations are performed on multiple pairs at the same time. This also allows you to change
the pair status for all the pairs in a group.
