Start and Stop of Components

To start or stop a component with NEC ESMPRO Manager, use the [Maintenance] tree of the component in the [ft] tree of the data viewer. Open the tree of the component to be started or stopped and select the [Maintenance] tree.

To start or stop a component with the Server Maintenance Utility, use the component screens of the Server Maintenance Utility.

The table below shows the potential cases in which a component is to be started or stopped.

IMPORTANT:

IO modules, SCSI adapters, SCSI buses, and modules under the SCSI enclosure have impact on each other. You need to be aware of this, for example, when you replace a CPU/IO module. For details, see “Impact of Module Status Changes” described earlier in this chapter.

When starting modules, ensure to start IO modules first and then CPU modules. To start IO modules when CPU modules are running and IO modules are stopped, the CPU modules must be stopped before starting IO modules.

CHECK:

Even if stoppage of a CPU module or IO module is requested, the module will not be stopped if it is judged that the system would be unable to continue running. It is the same for when the FT STATUS LED is off.

For example, the module is not stopped when the CPU/IO modules are successfully duplicated,
