EVM Server Logs

The EVM server log includes information about the following:

•Storage refreshes

•Job status changes

•EVM Command Line (EVMCL) and GUI update requests

•EVM host agent interaction

To prevent the EVM server log files from consuming too much disk space, EVM automatically archives the existing log file and starts a new one. Archiving occurs whenever the EVM server log file size reaches 10 megabytes or whenever the EVM server is restarted.

Seven generations of EVM server log files are maintained. A file named evm1.txt is the current log and evm7.txt is the oldest.

EVM Job Logs

Log files are kept for each EVM job. When a job runs for the first time, an EVM job log file (such as job_name.txt) is created for this job and the individual operations that comprise the job are recorded in the job log file. Detailed information about the job state also is recorded in the job log file. Each time a job is executed, the current EVM job log file for that job is archived and a new EVM job log file is created.

Seven generations of EVM job log files are maintained. The file-name format for an EVM job log file uses the EVM job name and a sequential number. For example, an EVM job log file named jobname_1.txt is the current log and jobname_7.txt is the oldest.

EVM Switchboard Logs

The Switchboard process implements EVM functionality on each EVM host agent computer. There is a Switchboard portion implemented on the host agents and another Switchboard portion implemented on the Management Appliance (EVM server).

View the EVM Switchboard log files (sb.txt) on the EVM server in the Log Report page. These logs contain primarily startup and initialization information about each EVM host agent computer in the EVM network. This information is used to diagnose host configuration, EVM host agent connectivity, and communication problems.

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.
