Veritas volume manager with on-line extension/mirroring

[Lacrosse]

Does anyone know if the on-line mirroring is included in the Volume manager HPUX LTU or do I need to order a separate veritas product to get the on-line extension/mirroring
Many thanks

Hi Horns!

According to the "VERITAS Volume Manager 3.5 Migration Guide", the base product offers the following features (which do not include mirroring):

VERITAS Volume Manager includes the following features:

* Concatenation, the combining of discontiguous disk regions into virtual devices.


* Spanning, concatenation across different physical media.


* Striping, distribution of storage mappings for a virtual device so that multi-threaded accesses tend to cause even use of all physical media.


* The VERITAS Volume Manager Storage Administrator, vmsa, a JAVA-based GUI for VxVM. The Storage Administrator runs either as an application or from a web browser.


* Dynamic Multipathing (DMP) for active-passive devices, such as Model FC30 and FC60. DMP provides higher availability to data on disks with multiple host-to-device pathways by providing a disk/device path failover mechanism. In the event of a loss of one connection to a disk, the system continues to access the data over the other available connections to the disk.


* Free Space Management, providing simple goal-based allocation of storage.


* Task Monitor, which tracks the progress of system recovery by monitoring task creation, maintenance, and completion. The Task Monitor allows you to pause, resume, and stop as desired to adjust the impact on system performance.

I should say that I think I remember hearing advice to the contrary, that's why I quoted the most recent manual I could find.
