This is the same received-command count as ciscoScsiLuInCommands, but as a 64-bit counter meant for logical units that receive commands fast enough to wrap a 32-bit counter between polls. On a LUN behind a high-IOPS flash array, this is the counter an admin should graph instead, since the 32-bit version could roll over past about 4.29 billion between 5-minute polls and produce a misleadingly low reading. A flash-backed LUN sustaining 50,000 commands per second would exhaust a 32-bit counter in under a day, making this 64-bit counter the only reliable one for that workload.
