# eqlvolume rethin
[--recommend | -R]
[--discard-usage | -D]
[--include mount-point | -i]

[--user-name user-name | -u]
The following table describes the optional command parameters.
Table 41. eqlvolume rethin Command Options
Parameter Abbr Argument Description
--recommend -R none Generates a list of volumes that appear to be good candidates for
thin-provisioning, but does not rethin any volumes.
--discard-usage -D none Displays a list of file systems that are incorrectly mounted with –o
discard, but does not thin-provision any volumes.
--include -i mount-point Specifies the mount points to be thin-provisioned. If this parameter
is omitted, all mount points using EqualLogic volumes will be
considered for thin-provisioning.
--exclude -e mount-point Specifies a list of the mount points that are not to be thin-
provisioned. If a mount point is listed with both --include and --
exclude parameters, the mount point is excluded.
--force -F mount-point Causes the specified volumes to be thin-provisioned, even if they do
not meet the thin-provisioning criteria defined by the
ReThinRecommend and ReThinRecommendMB configuration
parameters.
--group-access-file -g file-location Specifies the location of the group access file where the user names
and encrypted passwords are kept.
--user-name -u user-name If multiple user names have been stored in the group access file,
specifies a particular user identity.

Recommendations
This section provides examples showing how modifying an eqlvolume rethin configuration parameter affects the volumes that are
recommended for thin-provisioning. It also shows the verbose output of the--recommend parameter showing the reasons that volumes
were not recommended.
Example 1: Modifying an eqlvolume rethin Configuration Parameter
This example recommends a file system for volume thin-provisioning, modifies the --recommend parameter to change the minimum
percentage of space required to recommend thin-provisioning, and displays a different recommendation based on the new parameter
value. For more information on these parameters, see Volume Thin-Provisioning Configuration Parameters.
