Normalize Volume Operation

The normalize operation checks the status of the clone copy process and waits until normalization is complete on all units in the volume before starting the next step.

Suspend Operation

The suspend operation invokes an application-specific agent or utility on an EVM host agent computer, which places an application (typically a database) in the appropriate state for volume replication. The methods invoked vary, depending on the application. Refer to the appropriate application-specific EVM white paper for details.

In the Windows Clone Example on page 9–2, the batch file named

freeze_database.bat executes on the “dbserver” host using the WAIT parameter.

In the UNIX Clone Example on page 9–3, the script named freeze_db.sh executes on the “dbserver” host using the WAIT parameter.

Split Unit Operation

The split operation separates the normalized clone disk and creates a new independent BCV.

In the Windows Clone Example on page 9–2,three clones are split from the source units to create three BCVs. The $<name> variable allows EVM to automatically choose the unit number for the BCV.

Split Volume Operation

In the UNIX Clone Example on page 9–3, the split operation separates the normalized clone disk and creates a new independent BCV. The $<name> variable allows EVM to automatically choose the volume number for the BCV.

Resume Operation

The resume operation is the inverse of the suspend operation. The resume operation returns the application on the EVM host agent computer to the normal mode of operation.

Mount Unit Operation

After creating the BCVs and restoring the application on the EVM host agent computer to the normal mode of operation, the mount unit operation mounts the BCVs on an EVM host agent computer.

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.
