EVM Support for Volume Groups and HP Tru64 UNIX AdvFS Domains

This means that an attempt will be made to unmount any logical volumes which may be mounted.

Do you wish to continue (C for CONTINUE Q for QUIT):

If you enter Q, the script exits. If you enter C, the system processes the volume groups one at a time.

If you include the -qoption with the -aparameter, the beginning warning message does not appear; the system simply processes all of the volume groups that the script can find, one at a time.

A file is created in the VGmaps directory (/opt/CPQevm/bin/VGmaps) called failed_map_list, which contains a list of any failed volume groups. The logfile that gets created is in the logs directory and is called generate_mapfiles.logfile. The mapfile itself is created in the VGmaps directory; its name is in the format mapfile._vgname.

NOTE: If you attempt to generate a mapfile for the root volume group (default name vg00), which is usually included with the -aargument, the system does not allow you to do so. You get the warning message, “Could not create mapfiles for all Volume Groups.”

This warning message is also issued for other volume groups if, for any reason, the system cannot process the volume group and generate a mapfile.

Volume Groups and Windows 2000 Dynamic Disks

EVM V2.0D does not support Windows 2000 Dynamic disks. BCVs can be created from source units configured as Dynamic disks, but an attempt to mount these BCVs results in job failure. If the EVM host agent software is installed on a computer that contains Dynamic disks, the EVM Resources page for that computer displays two icons for each Dynamic disk. One icon shows the drive letter of the device with no physical device information. The second icon shows an unmounted physical device with no drive letter.

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.
