[Simh] Resizing the system disk

Hello again, Sergiusz, and thanks for your help.

Software RAID is another thing I want to study at some point,
especially when I get my I64 hardware. For now, though, I'm satisfied
that I learned how to use the Standalone Backup environment to
copy/backup/resize disks. With the RAUSER disk type, disks over 1.5 GB
are easy to set up.

Excerpt from SimH/VAX manual:

"RAUSER is a "user specified" disk; the user can specify the size of
the disk in either MB (1000000 bytes) or logical block numbers (LBN's,
512
bytes each).  The minimum size is 5MB; the maximum size is 2GB without
extended file support, 1TB with extended file support."
