Re: Decrease size of LUN.

Snapdrive can resize a lun larger or smaller... You can't shrink below the used space  https://library.netapp.com/ecm/ecm_download_file/ECMP1506027

Thanks, can we decrease lun size during production hour. is there any change to corrput file system. This volume contains log file of SQL Database.

Re: Decrease size of LUN.

To get comfortable with the process, you could clone the volume or lun, then safely test on the clone... Also, no matter what, before shrinking the production lun, create a snapshot from SMSQL, then you are protected if there is an issue on the resizing..
