Quick Reference Tasks Guide
Following are three tables of common tasks performed using De-Frag/X. These three tables consist of Analysis Tasks, Data Manipulative Tasks and Utility Tasks. More detailed information about all of these commands is available in the Commands List in Chapter 3, in the on-line help facility within De-Frag/X, or in the De-Frag/X User Reference Manual available from Lund Performance Solutions.


Analysis Tasks Description
De-Frag/X Command Sequence
Measure fragmentation on all disk drives
MAP ALL
Measure fragmentation on one disk drive
MAP<ldev> where ldev is desired logical device #
or MAP EACH will map each ldev
 
Measure fragmentation on one "chunk" of a MAP output
ZOOM ROW=<row> COLUMN=<column> where row and column dictate the chunk's position in the MAP command output
Find fragmented files on all disk drives
ANAlyze MIN# where # is the minimum fragmentation percentage to report
Find fragmented files on one disk drive
ANAlyze <ldev> where ldev is desired device #
Find fragmentation within a particular file
DisplayExtents <filename>
Counts the files on each disk
COUNTFiles <EACH>




Data Manipulative Tasks Description
De-Frag/X Command Sequence
Measure fragmentation on all disk drives
MAP ALL
Remove disk level fragmentation on all disk drives
CONDense ALL
Remove disk level fragmentation on one disk drive
CONDense <ldev> where ldev is desired device #
Create a desired amount of additional free space on a particular disk drive
MAKEROOM <ldev> <mb> where ldev is the desired device # and mb is megabytes of free space at add
Remove fragmentation within a particular file/fileset
DEFRAGment <filename | fileset>
Release unused space after the EOF on a particular file/fileset
TRIM <filename | fileset>
Balance the set of ldevs in the volume set specified
BALance <ldev> where ldev is the device to be balanced
Fragments the specified file(s)
FRAGment <filename | fileset>
