The Question is:
Is it possible to install OpenVMS on a specific drive partition, and how is
represented a partition of a drive ?
The Answer is :
Hardware partitioning can permit multiple operating systems per
spindle, with the specifics being controller-specific.
OpenVMS does not support software-based partitioning of disk drives,
akin to what is seen on Windows and IA-32 Linux.
Various Freeware packages can be used to provide a form of logical
disk partitioning within an OpenVMS system disk (or a data disk)
ODS-2 or ODS-5 disk volume structure, but the OpenVMS bootstrap
drivers assume that the entire volume is a contiguous unit under
the control of the OpenVMS file structure. These partitioning
schemes typically create a container file within the OpenVMS ODS-2
or ODS-5 file structure, and then use device drivers to access the
contents of the container file.
Given the dropping price of disk drives and (unlike the BIOS
"console" found on many low-end systems) given the ability of the
typical VAX or Alpha console to bootstrap directly off a specified
disk device, the OpenVMS Wizard does not particularly expect to
see disk partitioning support implemented within OpenVMS. This
is not, however, the first time that the OpenVMS Wizard has heard
what could be interpreted as a request to add this capability.
