Examining configured and used space of a LUN

Knowing the configured space and actual space used for your LUNs can help you determine the amount of space that can be reclaimed when doing space reclamation, the amount of reserved space that contains data, and the total configured size versus the actual size used for a LUN.

Example

The following example show the configured space versus the actual space used by the LUNs in the vs3 storage virtual machine (SVM):

lun show -vserver vs3 -fields path, size, size-used, space-reserve
vserver path              size    space-reserve size-used
------- ----------------- ------- ------------- ---------
vs3     /vol/vol0/lun1    50.01GB disabled      25.00GB
vs3     /vol/vol0/lun1_backup
                          50.01GB disabled      32.15GB
vs3     /vol/vol0/lun2    75.00GB disabled      0B
vs3     /vol/volspace/lun0
                          5.00GB  enabled       4.50GB
