Introduction to DFU
The online help for DFU provides a great introduction to the tool:
"The ODS-2 Disk and File Utilities (DFU) is a collection of high performance utilities developed to perform routine maintenance and special purpose operations on disks, files and directories. The functionality offered by DFU is not or partly available through other DCL commands or VMS utilities.
DFU has the following functions:
- DEFRAGMENT : defragment individual files
- DELETE : delete files by file-id, and delete directory(trees) fast
- DIRECTORY functions
- COMPRESS , DUMP or RECOVER directories
- Search directories for files with multiple versions, alias files or empty directories
- INDEXF : analyze , defragment truncate and extend INDEXF.SYS
- REPORT : reports disk fragmentation
- SEARCH : search for files
- SET : set file attributes
- UNDELETE : recover deleted files
- VERIFY : analyze (and repair) the disk structure"
Installing DFU on OpenVMS VAX 7.3
The DFU tool for VAX servers running OpenVMS operating system is available free online for download. I installed it on MARIAH (31.70) - my real MicroVAX 3100-80.To download DFU VAX:
[localuser@linuxpc tmp]$ wget https://www.digiater.nl/openvms/freeware/v50/dfu027a/dec-vaxvms-dfu-v0207-a-1.pcsi

Installing DFU on OpenVMS Alpha 8.3
Installing DFU on OpenVMS/Alpha is just like installing on VAX VMS. I installed it on RAPTOR (31.18) - an AlphaServer ES40 833 MHz running OpenVMS Alpha 8.3:
$ SHOW CPU
System: RAPTOR, AlphaServer ES40 833 MHz
CPU ownership sets:
Active 0
Configure 0
CPU state sets:
Potential 0
Autostart 0
Powered Down None
Not Present None
Failover None
$
First, download the OpenVMS/Alpha edition of DFU on a local Linux machine:
[localuser@linuxpc ~]$ wget https://www.digiater.nl/openvms/freeware/v70/dfu/dec-axpvms-dfu-v0301-1-1.pcsi
