Page 179 highlights

Volume information mismatch across cveva and Optimize There can be a mismatch on the Vdisk allocated size in ReTrim used space comparison with the host volume size shown by optimizer (slab count and volume information). Space reclaim is very minimal for iSCSI LUN during the file deletion. Based on the controller load, the efficiency of space reclamation might vary and the reclamation not start immediately. Reclaim of the specified space (or majority of the specified space) may complete over a period of time and may not be instantly. Thin Provisioning Threshold and Resource Exhaustion Test (LOGO) Failed The system event log when the threshold limit of the vdisk is reached, When the system event log reaches the threshold limit on the vdisk, the user can see an event on the LUN utilization capacity and pool availability capacity for LUN is restricted by either size of LUN or available capacity in pool. iSCSI module diagnostics and troubleshooting 179
