EVM Jobs and Job Management

Running several EVM jobs at the same time also creates the possibility of more than one job trying to use the same resource. Such conflicts should be rare in environments that have ample available storage resources. The best way to prevent the possibility of a job resource conflict is to make sure that jobs running simultaneously use storage resources located on different storage systems.

Job Naming Conventions

EVM V2.0D job names are not case sensitive; “EVMJOB1” and “evmjob1” are the same name.

EVM job definitions are stored as files, using the name of the job as the filename. Using certain characters in the job name (and hence the file name) can cause problems with the EVM Job Status page and the EVM Log Reporting page.

To prevent these problems, use only alphanumeric characters in the job name. Underscore (_) and dash (-) characters are safe to use in EVM job names.

NOTE: The online Help/User Guide includes a topic on illegal characters in the Troubleshooting section.

Aborting EVM Jobs

The EVM Abort command stops a currently running job at the beginning of the next operational step. The Abort function always waits for the current step to complete before stopping the job. This waiting period ensures that the corresponding “undo job” functionality can return the storage and host configuration to the pre-job state. This waiting period can be inconvenient, however, if the job is aborted during a normalize step, which can take a considerable amount of time to complete.

Continuing EVM Jobs

The EVM continue command restarts a job that has been stopped by a pause operation. The job is restarted at the step following the pause step. The continue command has no effect on a job that is not paused. If you decide not to continue past a pause step, you must first abort the job and then undo it; this is required to re-enable other job commands.

Validating EVM Jobs

The purpose of the EVM Validate command is to provide a reasonable degree of confidence that the job in question will run successfully. This degree of confidence is based on the storage and host configurations that exist at the time the validation is

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.
