Hi All,
We have provisioned 671 GB LUN which is resides in 1109GB Volume. Volume is thick and LUN is thin and it presented to VMware ESXi cluster. We have configured SMVI snapshots. Today morning LUN went offline due to space issue. Temporarily i increased volume size and broght LUN online. What are all the best practices available to prevent such incidents in future? If i set LUN reservation to ENABLED, won't it go offline?
