Hitachi Data Systems AMS, USP, and VSP

Foglight for Storage Management collects information from Hitachi Data Systems Adaptable Modular Storage (AMS), Universal Storage (USP) or Virtual Storage Platform (VSP) using the SMI-S interface of the HiCommand Device Manager component of the Hitachi Command Suite software or the embedded SMI-S provider of VSP arrays.

* 
NOTE: The information in this section applies to all three types of systems: AMS, USP and VSP.

The metrics that can be collected from the standard HiCommand Device Manager are limited. Foglight for Storage Management provides an option to interface with the Hitachi Tuning Manager to collect the following additional metrics.

Requirements for Hitachi Data Systems AMS, USP, VSP

Your environment must meet the following requirements:

•
The Hitachi HiCommand server is on a different server than Foglight for Storage Management.
•
For supported versions of Hitachi Command Suite, see Collection Target Support Matrix.
* 
NOTE: A HiCommand account must explicitly belong to the built-in Storage Administrator (View Only) or built-in ViewGroup User Group, and must be granted with the VIEW permission.
•
The SMI-S component is installed on the Hitachi HiCommand server.
•
The SMI-S component is installed on the Hitachi HiCommand server for AMS and USP arrays. For VSP arrays the embedded SMI-S provider must be enabled
•
Foglight for Storage Management requires a Command Suite account. By default, all Hitachi Command Suite users are also SMI-S users, so any Command Suite account can be used.
•
If you want to collect additional metrics with the Hitachi Tuning Manager:
•
The Hitachi HiCommand server is running on a Windows Server (so that Foglight for Storage Management can collect metrics from the Tuning Manager).
•
The Tuning Manager is enabled on the Hitachi HiCommand server. Tuning Manager is included in Command Suite 7.0 or later, but is licensed separately. For more information, see the Hitachi Command Suite Installation Guide.
•
Foglight for Storage Management requires a user account on the Windows Server hosting the Hitachi HiCommand server with the Tuning Manager enabled with the VIEW permission. The account must be configured to run the Tuning Manager.
•
By default CommandSuite (Device Manager) does not automatically refreshes data from Storage Devices that are connected to it. SMI-S is part of the Device Manager, so it does not refresh data as well. In order to make Device Manager refresh data following command below needs to be run on time schedule:
HiCommandCLI.bat" http://localhost:2001/service -u system -p manager RefreshStorageArrays

Configuring Agents to Monitor Hitachi Data Systems AMS

During this procedure, you configure an agent to monitor the server hosting the Hitachi Command Suite. You are prompted to select the arrays to configure. You can also configure the agent to use the Tuning Manager. For details, see Configuring Agents to Monitor Storage Devices.

Configuring Agents to Monitor Hitachi Data Systems USP and VSP Arrays

Monitoring VSP arrays requires a slightly different procedure than monitoring AMS arrays. When monitoring AMS arrays, the SMI-S provider that is part of the Hitachi HiCommand server is used. This is the same server that hosts the Hitachi Tuning Manager. When monitoring USP or VSP arrays however, SMI-S data must be collected from the SMI-S provider embedded in the array itself. The Tuning Manager on the HiCommand server is still used for performance data collection. For details, see Configuring Agents to Monitor Storage Devices.
