Can't seem to find a fix for the problem I have when I try to install VMS on simh.
I've created an ISO from the 7.2 Hobbyist kit and I can mount it on simhv38-1.
It starts to boot but it hangs on the write-locked to which I can't find an answer on the forums here or on google (as of yet).
>set rq0 rrd40
>att -r rq0 vms.iso
>b cpu
>>>b/10000000 dua0
%SYSBOOT-I-SYSBOOT Mapping the SYSDUMP.DMP on the System Disk
%SYSBOOT-W-SYSBOOT Can not map SYSDUMP.DMP on the System Disk
%SYSBOOT-W-SYSBOOT Can not map PAGEFILE.SYS on the System Disk
OpenVMS (TM) VAX Version X72T Major version id = 1 Minor version id = 0
%SYSINIT-E, %SYSINIT, error opening system dump file, status = 00000910
%SYSINIT, primary PAGEFILE.SYS not found; system initialization continuing
%SYSINIT, no dump file - error log buffers not saved
%SYSTEM-I-MOUNTVER, DUA0: has been write-locked. Mount verification in progress.
The ISO is mounted read-only, so sure it's write-locked. A CD-Rom device (RRD40) usually is read-only as well, right? So why does VMS lockup on the write-lock?
Hope anyone can help me. |

As you say ISO...how did you create your image? You need a plain ODS-2 image for your VAX to boot. Best to use dd
>>>b dua0 should be fine to start Standalone Backup. |

Im not sure if you can boot a full VMS on VAX from read-only media. OpenVMS on Alpha and Integrity has an extra system parameter WLKSYSDSK that you can set to tell VMS that the system disk is write locked. As far as I can tell the only arrangement of VAX/VMS that can be booted from read-only media is standalone backup. You can create a standalone backup kit with STABACKIT.COM. There may be an unofficial way around this limitation though. |
