This group is for all folks running the original IBM VM/370 Release 6 operating system (or later (e.g. VMTCE (Community Edition)) on Hercules. Like the other early IBM operating systems this version has always been in the public domain and so can be freely distributed. The base version as supplied by IBM is lacking in many facilities. IBM solved this by providing additional extension products which were licensed and so are not available. There are however many user enhancements available which can be installed. In addition, in order to get users up and running quickly updated "releases" of VM/370 included the most popular updates are available for download, so novices can start to learn VM without having to delve into the system internals. It is intended that this wiki will provide information on the base release and these updates.
The available versions are here :-

Re: Trying to access 191 give DMSLIO109S
Bertram, This is why I never bother with large disks. CMS Minidisks are limited in size by the CMS 800-byte file system. You get a maximum of just under 64k 800 byte blocks per disk which is 115

Re: Trying to access 191 give DMSLIO109S
You can create a mini-disk as large as the DASD but, from my quick test, the maximum number of 800 blocks for a mini-disk on a 3380 seems to be 65340, which corresponds to 121 cylinders. In other

Re: I forgot the VOLSER of drives (3380) I created
As I wrote before, I tested on a freshly downloaded VM/370 CE R1.2. My pleasure. :-) Well, like me, try it on a freshly downloaded version of VM/370 CE R1.2. If it works there, then the problem lies

Re: Trying to access 191 give DMSLIO109S
If I recall correctly, a 3380 only has 885 cylinders, not 886. (Unless you're using 'E' or 'K' models, but I'm not sure if VM/CE supports those.) [email protected]> wrote: -- Jeff Henry

Hello René, Yeah, I need to agree with you both that it is something here and I have zero idea where to go from here. Are we running the same version of VM/CE even with fixes? I want to thank you for

Trying to access 191 give DMSLIO109S
Hello, I'm getting DMSLIO109S when trying to access my 191 mini-disk. It is a 3380 (the entire drive 000 to 886). How large of a mini-disk does VM/CE support for 3380 DASD? Thank you.

Re: I forgot the VOLSER of drives (3380) I created
Hello Bertram, Well, I tried with 16 disks, BGM380 to BGM38F, and guess what, it works... all 16 disks are attached to the system! So, at this point, I am inclined to say you are doing something

Re: I forgot the VOLSER of drives (3380) I created
I have never done that! I think its a pain as EE does not support UPDATE directly. So you end up using UPDATE to generate an updated source, make a copy, edit with EE, use XCOMPARE to generate a new

Re: I forgot the VOLSER of drives (3380) I created
I just check: it works with or without shadow files, whether the disks are compressed or not, and whether I use SDL Hercules 4.7 or Hercules 3.13. Cheers, René FERLAND, Montréal

Re: I forgot the VOLSER of drives (3380) I created
Hello, I'm wondering there could be a bug-preventing VM from attaching these 3380 (380-38F, BGM380-BGM38F) via the SYSUSR macro? I can attach the drives manually (e.g., CP ATTACH 380 SYSTEM BGM380),
