To format, the VMS command is: INITIALIZE/DENSITY=double.
Both QBUS and UNIBUS interfaces are supported.
If you have XXDP for the PDP-11, you can format diskettes on an rx02
using
the ZRXE program. SSSD diskettes work fine.

OK. I've heard yea and nay on this count.
You're saying that on an RT-11 system (no OS/8 or its hardware to
play with), I can take an "IBM 3740 Compatible" SSSD disk out of the
box, run FORMAT/DOUBLE, and have an RX02 diskette? That would help
quite a lot.
AFAIK, yes... that's true. The RX01 media that DEC used to sell was
"IBM 3740 Compatible", and that's what I remember doing to "turn"
RX01Ks
into RX02Ks on an RT-11 system. If anyone has any contradictory
information, please feel free to pipe up.
Hmm. I need to see if I have a Qbus RXV21 that
can run in a 22-bit
system. Does VMS/VAX support RX02?
I'm pretty sure VMS supports it, but my only experience is with Unibus
hardware - an RX211 on a VAX-11/750. I would hope that an RXV21 works
in a Qbus VAX, but I can't speak from experience.
