VAXstation 3100 history (Was ... different)

Allison,or Anyone I recently got my MicroVAX I up and running it's MicroVMS 4.1 I listed devices and have an RD52 as DUA0. and an RX50 as DUA1 and DUA2 I did not see any directory commands to tell how much disk space is used/available. Are there any? Nor did I see any FORMAT command. (Which at this point I want to AVOID, because I don't understand the Backup process or target backup media capacity constraints. It sounds like backup clones the OS on the same drive in "renewed" and/or "rebuilt" files ) According to Allison's prior post, should I assume this RD52 is a 30MB MFM non SCSI drive? I also have a Plessy 6600/6700 system which has a 84MB-90MB drive which I think hangs on a DEC compatible SCSI controller. (I believe the Plessy is an LSI-11/34 clone.)The Plessy also has a Cipher F880 1600 bpi 9-track tape drive connected. Is there a chance I could Load the Hobby openVMS on either one, or both of these systems in a cluster? It seems to me the more capable system would be the Plessy with larger HD and Tape Unit already installed, (However I have never booted it, and I have no Idea what OS currently resides on it.) I believe someone gave an earlier response that the MicroVAX I was too small to run openVMS alone.
