2.7.3 EVAs are Types of Storage Cells
As of the current release of SEA, the SEA can monitor and process an HP StorageWorks Enterprise Virtual Array (EVA). HP's Command View EVA program is the software that manages an EVA. As of the current release, SEA supports EVA Storage Cells only on Windows 2000, Windows XP, and Windows 2003 on the Intel Pentium platform. Because it must be installed on the same machine as the ISEE Client, it cannot be a Windows XP host. 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 Command View 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 Command View. With the configuration data supplied by the user, SEA can fill in the appropriate information to be sent in problem report notification.
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 (Command View EVA server, EVA, WBEM Server) Commands" for more information on Managed Entity Command and Section 7.13 "Managed Entities" for more information on Web-based management interface.
EVA Storage Systems Status and Events
WEBES V4.5 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 V4.5 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:
- An array is powered up.
- A loop circuit is re-synchronized
- A link is lost
- A LIP command is invoked.
- The disk firmware does not meet the minimum revision
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 v4.5.
