EVM Jobs and Job Management

An EVM suspend operation with a DButil -pre command must have a matching resume operation with a DButil -post command. The DButil -post command closes open windows and returns SQL Server 2000 to normal operation.

An EVM launch operation with a DButil -restoresns command must be followed by application of one or more transaction logs to return the database to a normal state.

Obtaining the DButil Utility

The DButil script kit and its associated Solution Guide are available for download at

www.compaq.com/products/storageworks/solutions/rapidrestoresql/scripts.html

The download includes DButil.exe, attach and detach database script files, and documentation. The solution guide Rapid Restore for SQL Server 2000 contains detailed instructions for using DButil with EVM.

Storage Availability

StorageWorks storage systems are added to an EVM network through the Element Manager for StorageWorks HSG application loaded on the Management Appliance. The Element Manager controls all storage visibility for the Management Appliance. Only StorageWorks storage systems visible to the Management Appliance can be used in an EVM job.

NOTE: Refer to the Element Manager online Help for additional information and instructions.

Presenting Raw Units

Some applications, Oracle for example, use raw disks (disks with no file system) to improve I/O performance. You can use an EVM job to present raw disks (units) to hosts.

For example, assume that a job replicates a raw unit and names the copy $BCV1. To present the raw BCV as part of the EVM job, do the following:

1.Include a Mount Unit operation for $BCV1.

2.Select or manually enter the mount operation parameters, excluding the mount point.

3.For the mount point, manually enter N/A.

NOTE: In EVM V2.0D, use of the “N/A” mount syntax is qualified only in Mount Unit operations with Sun Solaris hosts.

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.
