SHAD-DSK-MAKER, Storage Management, Virtual disk OK with DEC shadowing Shadowing Unlike Disks This version of VDdriver permits one to make virtual disks of parts of other disks and works with Digital volume shadowing. Thus you can take unlike disks and make virtual disks out of parts of them, and shadow the parts. The remaining parts of the disks can be used either as separate virtual disks or as other file structures, if you decide to make file structures on the raw disks first and place the virtual disks on contiguous files on them. This code is presented as a "calling card" and works nicely with the author's product SAFETY. Please read the file "Safetyspd.txt" in this directory to learn about Safety, a comprehensive data safety package offering a reliable user undelete system, storage management, and data security functions unequalled anywhere in the industry. This version of the VDdriver is released for general use by GCE. Note that the file dfvax_shad_ok is an attempt at a retrofit for vax of the same techniques for making virtual disks work on vax with DEC volume shadowing. Use with asndf after set command asndf.
