I am wondering if it is now ok to covert ODS-2 volumes to ODS-5
There seems to be more and more HP based software like java, python and
others that require ODS-5 as their volumes. Is it now safe to run ODS-5
volumes for production systems.

You're right, "volume" refers to the top-level structure of a storage medium (hard disk, pendrive, etc.) which serves to identify the place of storage, rather than holding any actual data. Most commonly: "drive" or "partition".
The term was adopted in IT by analogy with "volumes" in the book world (think of "volumes" of an encyclopedia).

: wrong explanation, I'm afraid. // a point of method: defining "volumes" as "volumes" is not exactly a definition.

English term (edited):
volume (used for data storage)
logical unit/container for storing data
A "volume" is collection of data accessible trough the same "name" of the storage container holding a collection of data. The most well known example is the "drive C:" in Windows, but it's far from being the only type of "volume".
If a "volume" is the "top" of any hierarchical structure, it's the "top" of its own the directory tree - if data inside the volume is organised that way.
the hard disk is the physical support - it can be divided / partitioned in up to 4 "volumes" (in most systems), but the opposite is also possible - you can have a "volume" that spans several hard disks but as far as the operating system is concerned is just "one big collection of data" to which you get by first accessing/pointing to the "volume" first and then exploring the content of the volume, WHEREVER it's physically stored - all on the same hard disk or spread over several disks.
"volume" has to do with storing/accessing data - partitions and hard disks are just the physical support.
To make an analogy:
you can have a bunch of bundled paper (= the hard disk) containing 4 separate novels printed one after the other (= 4 "volumes" on the same hard disk)
inversely
you could have a very large printed text - say an Encyclopedia (= 1 "volume" in IT speak) printed not in one "bunch of bundled paper" but in several linked "books" (= a "volume" spanning several hard disks).

ODS-2 and ODS-5 are types of filesystems used by the OpenVMS operating system
https://en.wikipedia.org/wiki/OpenVMS
Enterprise-class environments typically select and use OpenVMS for various purposes including mail servers, network services, manufacturing or transportation control and monitoring, critical applications and databases, and particularly environments where system uptime and data access is critical.
not exactly the stuff for home users ...

: volume, ce n'est pas une unuté logique (logical unit). Vous confondez un peu tout....

volume, disk and partition are far from synonymous ...
So, The term "volume" becomes quite familiar. We are talking about things like Volume C in our computers.

A DISK is the physical storage medium, which can be split into several PARTITIONS. Once a PARTITION is formatted with a particular file system, it is called a VOLUME.
You could visualise this would be an analogy to a city; the DISK is just the land its built on. The PARTITION represents the city limits; so maybe there are two towns / partitions next to each other, and you want to know which city council has jurisdiction over a certain area. So we have two PARTITIONS. Now for the VOLUME, the city needs to be formatted, so the city council decides to follow the New York layout and says all roads running north-south are Avenues, and from east-west are streets. That's afile system that gives a framework for decoding any address. Now they build some roads (folders) and houses (saving a file), the city council can give those an address according to their scheme.
