EVM Jobs and Job Management

UNIX Clone Example

The following example illustrates the use of volume commands for a typical UNIX-based clone job:

CLONE VOLUME dbserver /mnt/lv00 2

NORMALIZE VOLUME dbserver /mnt/lv00

SUSPEND WAIT dbserver freeze_db.sh

SPLIT VOLUME dbserver /mnt/lv00 $BCV1

RESUME NOWAIT dbserver thaw_db.sh

MOUNT VOLUME $BCV1 backupserver 1 /mnt/lv00-bcv

LAUNCH WAIT backupserver backup_db.sh

Each operation is explained in the operation sections that follow.

Clone Operations

The following clone operations are applicable in both Windows and UNIX environments.

Clone Unit Operation

The first step in a clone job is to select the necessary disks and attach them to the specified source units to begin the process of normalization. In the Windows Clone Example on page 9–2, the clone operation starts on units D1, D2, and D3 on SUBSYS1, using a minimum redundancy value of 2 members.

Clone Volume Operation

The first step in a clone job is to select the necessary disks and attach them to the specified source units to begin the process of normalization.

In the UNIX Clone Example on page 9–3, the clone operation is started on logical volume /mnt/lv00, using a minimum redundancy value of 2 members. This starts the process of cloning all of the physical volumes that make up the volume group or domain that the mount point is based on.

Normalize Unit Operation

The normalize operation checks the status of the clone copy process and waits until normalization is complete on all clones before starting the next step. Although clone normalization occurs in parallel (all clones normalize simultaneously), normalize functions must be specified for each clone to make sure that all clones are completely normalized before the next operation starts.

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.
