The Question is: We have a uVAX-II/VMS 5.4 and would like to upgrade the OS. I gleened from the ASK THE WIZARD questions that the highest rev supported is 7.0. If we upgrade what size system disk would we need? The Answer is :
Information on the systems supported by OpenVMS, and on the size of
the system disk, are covered in the OpenVMS Software Product
Description (SPD). OpenVMS operating system SPDs are available at:
http://www.openvms.compaq.com/openvms/os/index.html
http://www.openvms.compaq.com/openvms/OperatingSystem.html
Based on the (attached) table from the OpenVMS V7.1 SPD, an RD54 disk
would be a tight fit, but can be supported. (The paging and swapping
files can be located on another disk, with minimal files on the system
disk for upgrades.) Further, the SPD indicates that the MicroVAX II is
supported by OpenVMS VAX V7.1.
