Stand/copy from tms(0,1) to ra(0,1) fails with a 'disk unlabeled' diagnostic on a cold disk image. It turns out that NetBSD's disklabel(8) will create a template disk image file that makes stand/copy happy, although I haven't verified that the label is all that it should be. The boot of the miniroot's GENERIC kernel does indeed fail. If only ra0 is configured for simh, it takes the kernel a long time to decide that ra1, ra2, and ra3 are offline. Having said that, I do not know how long this takes on actual hardware. This part can be speeded up by supplying empty image files for the remaing three disks, but in either case the kernel (and not simh) subsequently segfaults (trap type 8, code = c0000200, pc = 8003fe16). I haven't yet investigated what this diagnostic signifies. There are two likely scenarios, the kernel either crashes late in the ra driver initialization or while probing for the next device in line. At this point I'm not prepared to argue whether this is primarily an emulation error or a kernel bug. Owing to the lack of Vax hardware or at least a compatible environment, you have me at a disadvantage. Which function does pc = 8003fe16 correspond to?

Standalone format is what is known as low-level format in the PeeCee world (magnetic level stuff, certainly not needed on an emulator), and it has absolutely nothing to do with disk labeling. 4.3BSD-Quasijarus0[a] does not have standalone disklabel, but RA82 is known to the compiled-in tables and thus will work unlabeled. Also Ultrix' disk labels are not useful for 4.3BSD-Tahoe/Quasijarus, since the labels are stored in a different place in a different format. (Berkeley and DEC developed pack labels independently. BSD stores them in the boot block, Ultrix stores them in the root fs superblock, which has the disadvantage of requiring you to create some dummy root fs before you can write a label, even if you want a root fs of different size.) the Yes.
