Author ODS-5 with long filenames...

I have OpenVMS VAX 7.3 running on a modified VAX SimH emulator (getting 21.9 VUPS instead of the non-modified 19.3 VUPS). On one of my drives, not the system disk, I enabled ODS-5. Apparently this does not automatically support longer file names. How do I get filenames greater than 32 characters on OpenVMS VAX?

According to the documentation (http://h71000.www7.hp.com/doc/82final/5841/5841pro_081.html), long file name support is a Alpha/I64 OpenVMS feature. Spin yourself up a FreeAXP Alpha system to resolve the issue.

On OpenVMS/VAX you do not even have the option of enabling ODS-5 support on a disk.

An ODS-5 disk must be initialized on a AXP/IA64 system of new enough OpenVMS.

How did you modify VAX/SimH to get higher VUP rates?

I know there is an older fork that allowed multiple CPUs. It needs N+1 for linux so you need at least 3 CPUs to make it worth while. When I tested that fork, the SimH/Idle did not work.

Yes, you can enable ODS-5 on a VAX (from show device/full):

ODS-5 volumes can be mounted on the last versions of OpenVMS/VAX.

RMS can only see the filenames that comply with ODS-5.

There are some tricks that can be done. LIB$FID_TO_NAME or bypassing RMS can allow some access to the otherwise invisible files.

I reverted back to ODS-2 by creating a new disk that was ODS-2 then using ZIP/UNZIP to move the files from the old ODS-5 disk to the ODS-2 disk. I then re-initialized the original disk back to ODS-2.

Now for my next problem. When I attempted to create a saveset of the ODS-5 and then use the /CONVERT qualifier on the restore, I got an "unrecognized qualifier /CONVERT" error. Help BACKUP_Command shows the qualifier, but the DCL Tables don't recognize it. What do I need to do to be able to CONVERT the restore of a backup from a saveset containing ODS-5 files to an ODS-2 disk drive?

The help text should indicate that the qualifier does not work on VAX. If it does not, it is a bug.

As stated in the other thread, I was very unimpressed with what backup/convert did, and forgot to mention, it took a very long time before it failed for me because it unexpectedly ran out of disk space, and I had more than enough disk space to manually do the ODS-5 to ODS-2 conversion.

HPE only makes the most current version of OpenVMS Alpha / IA64 /VAX available to hobbyists. When I had access to the Alliance 1 program it was the same. No public downloads are allowed by HPE.

lation/ For the most part just use VMS 6.1 media instead of 7.3. But why run the older release?

Where can I find the write up on running VMS 6.1 using the simh emulator?
