Hi,
Can I mount an AXP OpenVMS (7.11H2) disk in a VAX virtual machine (SimH)?
It complains about something and mount was unsuccesfull. :-(
AXP disk is a VMS boot disk what I want to examine without booting it. I search some file ...
TIA, |

Unless the disk is too large for the version of VAX VMS you are running or is set up as ODS-5, it should mount without issue. Make sure you have the sizing parameters right in the SimH configuration file. |

Hi,
The image size is 4GB. (HSZ22)
How can I check the ODS version? I'm not an VMS expert ...
I will check soon the output of mount command. I think it will give some more information the error message.
TIA, |

I would suspect that the disk label was incorrect or not known at the time of mounting. Try the following command variant:
MOUNT/OVER=ID
This should mount the disk to your process without having to know the disk label.
Given that this is a V7.1-1h1 disk, I doubt that it is an ODS5 disk.

Hi,
Mount under FreeAXP:
$ mount/over=id dka300
%MOUNT-I-MOUNTED, ALPHA_711H2 mounted on _AXP1$DKA300:
$ sh dev dka300

So as I can see it is ODS-2. Is that true?
Soon I'll try to install a 7.x OpenVMS in SimH VAX and try to mount it again.

I think the problem is the size or type of the disk (RA92 <-> HSZ22)!
RA92 is an 1,2GB disk and I don't know what is HSZ22. Is that a disk or a RAID controller?
How can attach this 4GB disk image to SimH (VAX)? As user type?
TIA, |

HSZ22 is a generic disk type. It is not the issue. It looks like you have a corrupted disk image file. You could run Alpha VMS from an installation CD and see if you can mount the disk. If not, you'll need to recreate the volume. |

Hi,
My image is running under FreeAXP and I can mount it under FreeAXP with OpenVMS 8.4.
I wanted to mount under VAX machine because I don't have to use FreeAXP checking or searching files on the disk.
HSZ22 was told by FreeAXP. It is a 4GB image from a Fujitsu M2954ESP SCSI disk with Linux dd command.
TIA, |

If the volume mounts under Alpha OpenVMS (FreeAXP) and is not ODS-5, it should mount under VAX OpenVMS (SimH). My best guess at this point is that the disk sizing is wrong in the SimH configuration file. |

Hi,
What is the maximum disk size in VAX? I read somewhere it is RA92? (1,2G
My image is 4GB. How can I mount it then?
TIA, |

VMS 7.3 can handle much bigger than 4GB. You need to declare the disk size explicitly, something like this:
set -L rq2 RAUSER=8378368
att rq2 D:\VAX\DUA2.img

Hi,
Defining the disk size with the rauser= parameter, the mount was successfull!
Thank you very much! |
