Welcome to OpenVMS (TM) x86_64 Operating System, Version V9.1-A
Username: 

We are excited to announce the availability of VSI OpenVMS V9.1-A for x86-64. This is the next step in the journey to migrate OpenVMS to the x86-64 platform. The V9.1-A release allows you to use the operating system with some of your favorite hypervisors and includes a host of newly migrated applications.


You can participate in the field test if you are a customer or partner of VSI with a valid support contract. Please fill in this form to receive credentials for the Service Platform where you will be able to download files and report issues. See below for instructions on how to use the Service Platform.

To determine if your hardware can run OpenVMS 9.1-A, run this Python script on the hardware in question. Information on the virtual machine hosts tested by VSI is provided below and in the release notes. If you need to compile and link your source code, you will need an Integrity running OpenVMS V8.4-2L1 or higher because OpenVMS V9.1-A does not have native compilers yet.

Download Script

Take a look at this video that explains how to use the VSI Service Platform to download 9.1-A and report bugs. Be sure to check this web page and the VSI Service Platform periodically for updates.

  • Initial DL380 support (FC storage and boot, i350 Intel NICs, P440 Smart Array)
  • TCP/IP Services X6.0-12 for OpenVMS
  • New version of OpenSSH provided separately
  • VAX floating point supported by all compilers but Fortran
  • Cluster Common System Disk support
  • Additional open source products: OpenLDAP, Stunnel, Vgit
  • Additional layered products: DECnet-Plus, DCPS

The V9.1-A UPD V1 kit for installation on a V9.1-A system is available on the Service Platform.

VSI$SUPPORT.COM is a script that generates reports about your system necessary for VSI Support to investigate the issue. You can get it here.

When installing DECnet-Plus, you will see the following messages:

%PCSI-I-PRCOUTPUT, output from subprocess follows ...

%SYSGEN-W-SETMAX, value set to maximum for parameter GHEXECCODE

This is a known issue that does not affect the installation.
