IMAGE mode is for non-vms-backup disk dumps, just N disk blocks ! per tape block, no labels or other info there. qualifier IMAGE ! skip just skips files before starting. We rewind the tape and ! skip these because we must know where we are. qualifier SKIP,value(required,type=$number) qualifier TRK,value(required,type=$number) qualifier CYL,value(required,type=$number) qualifier SEC,value(required,type=$number) qualifier TCACHE,value(required,type=$number) qualifier CACHE,value(required,type=$number) ! Add /norewind switch to be used with /skip:0 (and force skip:0) ! to assume the current tape location is the start of the disk ! image. If you have something weird like a TAR dump of a disk ! image of a virtual disk, and skip the header block somehow, this ! might prove useful. Rare, but it's easy...let's have it in there ! for the oddball who really must have it... qualifier NOREWIND qualifier IGNCRC qualifier FRCCRC qualifier IGNXOR qualifier CRC qualifier FILE ! file unused ;unused qualifier CLEAR ! Specify cache in pages (cache) or in tape blocks (tcache) ! not both. Better to make the user make up his mind rather ! than rely on some programmatic default. disallow CACHE and TCACHE ! Image mode means not vms backup. Disallow image mode and switches ! that have meaning for backup only, just to make this easier NOT ! to get messed up with. Won't help user who confuses this much, ! but /image mode is not a default. We need to help the user not ! play too meaninglessly. disallow IMAGE and CRC disallow IMAGE and IGNCRC disallow IMAGE and FRCCRC disallow IMAGE and IGNXOR ! Note: CLEAR switch is for FDHOST.MAR only. It just zeroes the ! reference count of the FD: unit in case aborting control tasks ! left this nonzero. ! Uses FDHSTIMG to create a read-only virtual disk out of a ! back/physical (or hsc backup) saveset or a disk dump to tape ! using dtdriver.
