Disk Storage Manager graphical user interface
(GUI) or command-line interface (CLI). The GUI
includes wizard-based tools and a task-based
structure designed to simplify installation, con-
figuration, management, and diagnostic tasks.
Modular Disk Storage Manager enables admin-
istrators to discover storage systems through
either Serial Attached SCSI (SAS) or Ethernet,
troubleshoot using diagnostic utilities, and
manage virtual disks, hot-spare drives, firm-
ware upgrades, and event logs (see Figure 4).
It includes both in-band and out-of-band man-
agement capabilities, along with an optional
event monitoring service (used to send alerts
when a critical problem occurs).
In-band management is available when the
PowerVault MD3000 is connected to the host
server using SAS and Modular Disk Storage
Manager is fully installed, including the host-
based storage agent, multipath drivers, and
management station package. Out-of-band man-
agement is available when client systems can
connect to the PowerVault MD3000 using
Ethernet and the Modular Disk Storage Manager
management station package is installed.
The Modular Disk Storage Manager CLI gives
administrators direct access to a script engine
utility that reads commands and runs script files.
Tasks administrators can perform using the CLI
include the following:
•
Create script command batch files when
installing the same configuration on multi-
ple storage arrays
•
Run script commands on a storage array
directly connected to a host, a storage array
