Manage the system state

You use the nzstart to start system operations. You use the nzstop command stop the Netezza Performance Server system operations. The nzsystem command provides more state change options, such as pausing the system, resuming the system, and restarting the system.

All nzsystem subcommands, except the nzsystem showState and showRev commands, require the Manage System administrative privilege. For more information, see Table 1.

Note: When you stop and start the Netezza Performance Server system operations on a Netezza® C1000 system, the storage groups continue to run and perform tasks such as media checks and health checks for the disks in the array, as well as disk regenerations for disks that fail. The RAID controllers are not affected by the Netezza Performance Server system state.
