Hi Erico,
Depends on the LUN and what its doing.
If the volume is full then this will then take the LUN off line to ensure that your Windows environment doesn’t try to write to a LUN that no longer has space in its supporting volume.
The LUN itself can also fill up dependent on the type of things going on…If there is a lot of adding and deleting files then this can take up LUN space, even though Windows thinks there is plenty of space…
Space reclamation frees that space up…but does create a big backup next time around.
But start with checking available volume space and go from there…
