ultrix on simh

Hi, I'm running Ultrix V2 on Simh quite happily today and have a couple of goals I don't know how to accomplish. I'm hoping someone here can help. First, the tape I installed from created two very small virtual disks and filesystems on rl00 and rl01. I would like to be able to create a third virtual disk with more space so I could actually get some work done. Does anyone know how to create and mount a new filesystem on a new virtual image under simh/ultrix? Second, I would maybe like to upgrade to Ultrix 3.1, maybe on a vax if it is supported. Is there a howto for doing so under simh, including where to find a good boot tape? Third, I would like to find and install the online manuals, which were missing from my distribution. Unfortunately, I have not been able to find them. Are they available online, or does someone have a set they can tar up and share? I'm pretty UNIX savvy, but I really started getting deeply interested and involved in the SYSVR2 days. My experience with DEC hardware and software from an administrator's position is nonexistent, but I really want to learn. Someday I would actually like to have a microvax running UNIX here to play with. But that's another story. Thanks in advance for any wisdom you can impart. Tom
