Troubleshooting

EVM GUI Takes a Long Time to Load

The EVM GUI makes extensive use of Java applets. When a new Web browser session is established, applets may take a minute or more to download, depending on current network conditions. After the applets are downloaded, they remain stored in the Web browser cache until a new browser session is established.

30-Minute Spawn Process Timeout

By default, the EVM host agent is configured to time out and report an error if a process spawned by a suspend, resume, or launch operation does not complete within 30 minutes. In some cases, the spawned process may require more than 30 minutes to complete. For this situation, do the following:

1.Modify the PIPE_READ_TIMEOUT value in the sb.ini file, on the appropriate EVM host agent computer, to reflect the desired value (in seconds).

2.Restart the EVM service on the EVM host agent computer to make the changes take effect.

Accuracy of Step-Percent-Complete Bar

Sometimes the step-percent-complete bar on the Job Monitor page may drop from a larger percentage to a smaller one. This does not necessarily indicate a problem.

For example, a clone normalization step may reach 100% and then drop down when two jobs that normalize the same unit are both running. Because EVM displays the average percent complete of all mirror members, the percent-complete bar in one job may drop to a smaller percentage when the second job begins its normalization.

EVM Host Agent Connectivity Troubleshooting

The bidirectional communication between the EVM server and the individual EVM host agent computers is accomplished through an encrypted TCP socket interface. For this communication interface to work properly, the following must be true:

•Each EVM host agent computer must be able to resolve the network name of the Management Appliance (EVM server).

•The Management Appliance (EVM server) must be able to resolve the network names for each of the EVM host agent computers.

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.
