When most components are reset, a graceful shutdown is performed and a reboot is attempted. Before starting a reset of a node chassis, processing node cabinet, VMS, or VM node, you must shut down the appropriate applications to ensure data integrity.
If a component fails the reset, you can, as a last resort, perform a hard reset. A hard reset is an immediate reset of the node, VMS, or VM node. Because data corruption on the nodes can occur, you should only perform this command when all other attempts to reset have failed.
The following table lists the components that can be reset.
|Node Cabinet||Attempts a graceful shutdown and reboot of the nodes in the cabinet.|
|CMIC||Reboots the CMIC.|
|Node Chassis||Attempts a graceful shutdown and reboot of the specific node.|
|VMS||Attempts a graceful shutdown and reboot of the VMS. This also resets the VMs on the VMS.|
|VMs||Attempts a graceful shutdown and restart of the VM.|
|Ethernet Switch||Resets the Ethernet switch. The ports on the attached devices are unavailable during the reset.|
|InfiniBand Switch||Resets the InfiniBand switch. The ports on the attached devices are unavailable during the reset.|
|Dot Hill (DH) Disk Array||Resets the DH Disk Array. During the reset, the array is off-line and the associated storage devices are unavailable.|
