Hi All,

I have got an alert for my volume threshold reached as the space left on volume was only 12MB out of 107MB i have lun on top of this Volume which is of size 102MB, i have conveyed the client about this but he was telling the lun what he is using on the windows side it was showing 61.1 MB free , so could anyone please explain about this.

Thanks,

Nayab

You may need to check the size of the snapshots and delete them to free up the space. Also, see if snap reserver is 0.
