Troubleshooting

To enable use of the 1.3.1 Java Plug-in after uninstalling 1.4, manually copy the NPJava*.dll files from the 1.3.1 <jre directory>/bin directory to the <Netscape6 install directory>/plugins/ directory.

Sun Solaris Browsing Computers

Patches and Kernel Update for Solaris. When installing the J2SE 1.4 platform (JRE 1.4) for the Solaris operating environment, be sure that you have the proper patches installed. To obtain patches, see the SunSolve support website.

Uninstall-bug on Solaris. A bug in the uninstall scripts for packages SUNWj3rt and SUNWj3dev prevents those packages from being removed during a Disk Space Reallocation (DSR) upgrade. With a DSR upgrade, these packages must first be manually removed using the pkgrm command. See Solaris bug report 4635483 for more information.

OpenWindows Bug. When running J2SE 1.4.0 on the Solaris operating environment, behavior in conformance with the Java 2 Platform specification is not guaranteed when using OpenWindows. In particular, some APIs related to handling focus, such as the Component.requestFocus() method, fail when using OpenWindows. This problem is due to a bug in OpenWindows. See the Solaris bug report 4505899 for more information. The bug does not exist in the CDE window manager.

Replacing or Renaming a Management Appliance

Refer to the SANworks Enterprise Volume Manager Version 2.0 (Multi-OS) Installation Guide for information and procedures to replace or rename a Management Appliance during a network update.

Changing Storage Configurations While Jobs Are Running

If the configuration of a storage system is changed (externally to EVM) while jobs are running, the changes may cause the jobs to fail. In some cases, the ability to undo jobs that fail in this manner may be impaired and manual cleanup of the storage configuration may be required.

To prevent such problems:

Make sure that the storage configurations remain stable while running EVM jobs.

Always perform a manual EVM storage detection after making changes to the storage configuration (see “Detect Storage Properties” on page 5–22). The detection makes EVM aware of the storage system changes.

Enterprise Volume Manager Software specifications

HP Enterprise Volume Manager (EVM) Software is a robust solution designed to optimize storage management for enterprise environments. This innovative software addresses the complexities of managing data across diverse storage systems while enhancing performance, scalability, and efficiency.

One of the key features of HP EVM is its ability to centralize storage management. By providing a unified interface, it streamlines administrative tasks, enabling IT teams to manage storage resources from a single console. This centralization not only simplifies operations but also reduces the potential for human error, leading to more reliable data management.

Another significant feature is the software's powerful automation capabilities. HP EVM automates routine tasks such as data provisioning, monitoring, and reporting. This functionality empowers organizations to allocate resources efficiently, respond to changes in demand swiftly, and ensure optimal performance without extensive manual intervention. Automated alerting and reporting mechanisms provide visibility into storage utilization and performance metrics, allowing for proactive management of storage resources.

HP EVM also supports advanced storage technologies like thin provisioning and deduplication, which help maximize storage efficiency. Thin provisioning allows organizations to allocate storage on an as-needed basis, minimizing wastage and ensuring cost-effective utilization. Deduplication, on the other hand, reduces redundant data, freeing up valuable storage space and improving backup and recovery times.

Scalability is another hallmark of HP EVM. The software is designed to grow with an organization's needs, supporting a wide array of storage devices, from traditional disk systems to flash storage. This flexibility ensures that enterprises can adapt to evolving data demands and technological advancements without overhauling existing infrastructure.

Security features integrated into HP EVM are essential for protecting sensitive data. The software supports robust encryption protocols and access controls, ensuring that data remains secure during transitions and while stored across multiple locations. Compliance with industry regulations is facilitated through comprehensive logging and reporting features, enhancing an organization’s ability to maintain regulatory standards.

In conclusion, HP Enterprise Volume Manager Software is a pivotal tool for organizations seeking efficient and effective storage management. With its centralized management capabilities, automation features, support for advanced storage technologies, scalability, and strong security measures, HP EVM stands out as a vital asset that drives operational efficiency and data integrity in today's data-centric enterprises. Investing in HP EVM not only simplifies storage management but also empowers organizations to proactively meet their data challenges.
