CLI
CLI is text-based interface supported by Device Manager. Using CLI enables you to
perform certain tasks (such as the initial installation of a system or applying the same
changes to settings in many locations) more efficiently. For details on the computer
requirements for using CLI and how to use it, see the HP StorageWorks XP Command
View Advanced Edition software Device Manager CLI user guide.
Host (application server)
A host (application server) is a computer that uses the volumes in a storage subsystem.
Device Manager agent
A Device Manager agent is a program that collects information about hosts and storage
subsystems, and reports that information to the Device Manager server. This program must
be installed if you use Device Manager to manage host information and the volume usage
states on each host, or if you use XP Provisioning Manager. For details on the computer
requirements for using the Device Manager agent and how to use it, see the HP
StorageWorks XP Command View Advanced Edition software Device Manager agent
administrator guide.
XP RAID Manager
XP RAID Manager is a program that controls copy pairs on a storage subsystem.
This program must be installed to use Device Manager to provide consolidated
management of copy-pair configurations and statuses. For details about how to install the
XP RAID Manager, see the XP RAID Manager documentation.
Storage subsystem
The storage subsystems (shown in the figure) are managed by Device Manager and XP
Provisioning Manager. For details on the system requirements for storage subsystems, see
section
1-4 .
1-2 Network configuration
HP StorageWorks XP disk arrays come equipped with a service processor known as the SVP. The
SVP has two Ethernet adapters. The first adapter is for a private (internal) Ethernet LAN, which is
intended for intra-array communications only. Only two devices can access the internal LAN: the
SVP and, for XP512/XP48, the Remote Console. The second adapter is used for other applications
to communicate with the SVP. This LAN is referred to as the public LAN because it is visible to other
computers outside the array. Device Manager uses the public LAN to communicate with a storage
subsystem and with an SVP used to make configuration changes to a storage subsystem.
CAUTION: XP24000/XP20000, XP12000/XP10000/SVS200, XP1024/XP128, and XP512/XP48
have a public LAN and a private LAN. Device Manager uses the public LAN to communicate with
the SVP about the array and configuration changes. Do not under any circumstances attach the
private LAN to an external network because this can cause serious problems on the array.
