I have a Charon-AXP test system with two virtual disks. The Migration Specialties web site mentions that the virtual disks are compatible between Charon-AXP and their emulators. They suggest testing the compatibility using FreeAXP. The problem that I run into is that the virtual disks on the Charon-AXP virtual alpha are defined as 18 GB Seagate ST118202L's. The Charon-AXP emulator provides a file with meta data for this drive configuration:
VirtualDisk>
<Geometry>
<BytesPerSector>512</BytesPerSector>
<SectorsPerTrack>0</SectorsPerTrack>
<TracksPerCylinder>62620</TracksPerCylinder>
<CylindersPerUnit>31310</CylindersPerUnit>
<SectorPerUnit>35843686</SectorPerUnit>
</Geometry>
<MSCP>
<MediaTypeClass>DK</MediaTypeClass>
<MediaTypeName>ST118202L</MediaTypeName>
</MSCP>
<SCS>
<NodeName>ST118202L</NodeName>
<SystemID>0</SystemID>
</SCS>
<SCSI>
<Vendor>SEAGATE</Vendor>
<Product>ST118202L</Product>
<Revision>0200</Revision>
<UDID></UDID>
<WWID></WWID>
</SCSI>
<Special>
<BadBlockTable>FALSE</BadBlockTable>
<Description>SEAGATE CHEETAH ST118202L 18 GB</Description>
<ControllerId>SCSI</ControllerId>
</Special>
</VirtualDisk>
I can define the disk in the Free-AXP configuration GUI and it certainly recognizes it as a disk but it doesn't know what to do with the disks's geometry (or so it would appear) as it cannot find the boot block on the system disk. Is there a way to get the FreeAXP emulator to properly recognize these virtual Seagate ST118202L drives? |

Try pointing at the Charon disk file from FreeAXP without modifying the disk settings. Just define it as a 18GB drive. |

My notes and my memory both failed me. The problem was that I had incorrectly associated the files with the devices (I had made the system disk the data disk and the data disk the system disk) Once this was corrected VMS booted as expected. Only the usual minor changes were necessary as would be expected if I had moved the OS and data disks to a smaller system (working set size was adjusted for the smaller amount of memory).
The simple definition of the disk as an 18 GB drive was the only specification on the drive in the Free AXP emulator and it worked just fine (after I fixed my mistake). Thank you for the suggestion.
