NOTE: It may be necessary to disable the SCSI unmap support in Windows 10 and Windows Server 2012 R2 or later if you
are using replicated volumes (including SyncRep). It may also be required that you disable automatic file system
defragmentation in Windows Server, and disable both the unmap and the defrag features. However, if you disable the
unmap support, the Host Integration Tools rethinning tools will not work, in which case you must use the Disk Optimization
tool built into Windows to rethin a volume.
Run the EqlRethin Utility
The EqlRethin utility is located under the default installation folder, or the folder that you specified for HIT during installation.
The default folder is: C:\Program Files\EqualLogic\bin
NOTE: You must be logged in to the host as an administrator to run this utility.
1. From the Start menu, right-click Command Prompt and select Run as administrator.
2. In the command window, change the directory to: C:\Program Files\EqualLogic\bin
3. Enter the command eqlrethin to display the syntax for the utility.
EqualLogic Volume Re-Thinning Utility
Usage:
EqlRethin [OPTION] volume0 [volumeN]...
EqlReThin options:
-h [--help] Display this text
-a [--analyze] Show the possible results of rethinning a volume but do
not rethin
-d [--defragment] Defragment volumes before rethinning
-n [--nounmap] Skip sending SCSI unmap commands to the volume
-p [--percentage] arg <=90> Percentage of free space to rethin
Defragmenting a volume before rethinning can improve rethinning results, but can also take hours to execute.
4. To rethin a volume called tvol01 and defragment it first, enter the following command: eqlrethin -d e:\
NOTE:
Because defragmenting a volume can take up to several hours, Dell recommends using the defragment option
only on volumes that are known to be fragmented, or where performing the volume rethinning operation alone does not
return as much space as expected.
