2.7.3  EVAs are a Type of Storage Cell

As of the current release of SEA, there is only one type of Storage Cell that SEA can monitor and process which is a HP StorageWorks Enterprise Virtual Array (EVA). HP's CommandView EVA program is the software that manages an EVA.

As of the current release, SEA only supports EVA Storage Cells on Windows 2000, Windows XP, and Windows 2003 on the Intel Pentium platform. SEA is intended to support managed entities on other operating systems and platforms in the future.

SEA can monitor and process events logged by the EVAs to the system's binary event log via CommandView EVA. SEA displays the information in the web interface by automatically analyzing events from such entities and by sending notifications when appropriate, much like the functioning of SEA with a node's binary events. SEA can gather configuration information about the EVAs from the CommandView. With the configuration data supplied by the user, SEA can fill in the appropriate information to be sent in problem report notification.

The CommandView EVA software must be installed for SEA to process EVA events.

Note


WEBES v4.4 and later requires CommandView EVA (CV EVA) v3.2 to be installed on systems that manage HP StorageWorks Enterprise Virtual Arrays (EVAs). In addition, WEBES v4.4.3 now supports the gathering of status and error data from the fiber ports associated with EVA storage subsystems. For this feature to work correctly CV EVA v4.1 is required. If you connect to CV EVA of a version earlier than v4.1, WEBES will work but it will not collect fiber port status data. Regardless of this new feature, WEBES recommends installing the latest version of CV EVA to take advantage of the latest improvements and features in CV EVA.


During the WEBES installation process, you are prompted to enter configuration information for any managed entities detected on the node where you are installing WEBES. This information is included with the results of SEA analysis. If an entity is not fully configured during WEBES installation or a new entity is detected later, the Web interface prompts for the entity configuration information, when the user logs in.

Refer to Section 3.13 "Managed Entities (EVAs) Commands" for more information on Managed Entity Command and Section 6.13 "Managed Device Entitlement" for more information on Web-based management interface.

EVA Storage Systems Status and Events

WEBES V4.4.3 now supports the gathering of status and error data from the fiber ports associated with HP StorageWorks Enterprise Virtual Array (EVA) storage subsystems.

The EVA status and error data is reported to the EM-Client, which is part of the HP StorageWorks Command View storage management application.

The port data that can be collected is related to:

By default, WEBES V4.4.3 polls the EM-Client for fiber port status every 12 hours.

This new EVA fiber port support allows HP StorageWorks Serviceability Engineering to write rules that present status information and error callouts in the Command View application. These rules will support the following assets:

The current port status is kept in memory for 24 hours, after which it is removed

These new EVA fiber port rules will be available as future rules updates to WEBES v4.4.3.
