Volume and Unit Commands

Source volumes (volumes that are to be replicated) can be specified by volume name rather than by the unit they are based on. To implement this command style, the CLONE, NORMALIZE, SPLIT, SNAP, and MOUNT commands have been divided into two versions: VOLUME and UNIT.

Volume-style commands allow the source volume to be specified as a volume (drive letter or mount point) on a specific host:

CLONE VOLUME aix_server_name /mnt/lv00 2

CLONE VOLUME windows_server_name F: 2

Note also that UFSs created on Logical Storage Manager (LSM) volumes are not supported.

Unit-style commands are the same as they were in EVM V2.0. Source volumes are specified in terms of their storage system and unit number, as in the following example:

CLONE UNIT SUBSYS1 D2 2

NOTE: For IBM AIX hosts, HP recommends using only the VOLUME syntax for snap and clone operations. For Tru64 UFSs (UNIX file systems), unit- or volume-based job steps are valid; but, for domain-based file systems, only volume-style job steps are valid.

Windows Clone Example

The following example illustrates operational sequences for a typical Windows clone job:

CLONE UNIT SUBSYS1 D1 2

CLONE UNIT SUBSYS1 D2 2

CLONE UNIT SUBSYS1 D3 2

NORMALIZE UNIT SUBSYS1 D1

NORMALIZE UNIT SUBSYS1 D2

NORMALIZE UNIT SUBSYS1 D3

SUSPEND WAIT dbserver “freeze_database.bat”

SPLIT UNIT SUBSYS1 D1 $copy_db1

SPLIT UNIT SUBSYS1 D2 $copy_db2

SPLIT UNIT SUBSYS1 D3 $copy_db3

RESUME NOWAIT dbserver “thaw_database.bat”

MOUNT UNIT SUBSYS1 $copy_db1 backupserver 1 t:

MOUNT UNIT SUBSYS1 $copy_db2 backupserver 1 u:

MOUNT UNIT SUBSYS1 $copy_db3 backupserver 1 v:

LAUNCH WAIT backupserver “backup_db.bat”

Each operation is explained in the operation sections that follow.

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.
