Remote Web Console Gui; Raid Manager And Consistency Groups; Initial And Update Copy Operations - HP XP P9500 User Manual

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

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 system.
With the GUI, you enable the Business Copy license key, configure the system, perform copy
operations, and perform monitoring, maintenance, and troubleshooting.

RAID Manager and consistency groups

RAID Manager can be used to perform most of the same operations as with Remote Web Console,
but using a command line interface. Pair operation commands are issued directly from the host.
Business Copy pair operations can also be automated with RAID Manager using scripts.
Using RAID Manager, you can specify multiple pairs as a consistency group. With a consistency
group, pair operations can be performed on multiple pairs at one time. This also allows you to
change the pair status for all the pairs in a group.

Initial and update copy operations

When you create a pair, the system executes an initial copy. When the pair is created, the storage
system asynchronously copies updates received by the P-VOL to the S-VOL.
