We have a LUN in Equal logic that shows full (1tb) but there is only 916tb on the drive. How can I change it to show the proper amount of data available on the drive?
You have to check if you meet the requirements for using scsi unmap/space reclamation within you Guest OS. Together with HIT and EQL FW and a thinprovisioning Volume.
As a Block device a EQL volume doesnt know when a upper Filesystem deletes data because the FS only mark this data as deleted and wait for overwriting it with new data when needed. So a EQL volume only see the data consumtion as a high watermark. Thats total normal for a block device storage.
