Field engineers shall perform parts replacement. The flow of maintenance is as follows:
When stop maintenance is to be performed
All the nodes of the running PRIMECLUSTER system shall be stopped by the administrator of the PRIMECLUSTER system.
Pass the operation over to field engineers.
Field engineers shall then perform maintenance of the erroneous location (repair or replacement). Confirm that the system operates normally by running a test program, etc.
After the completion of maintenance by field engineers, check the relevant equipment and then boot the PRIMECLUSTER system.
When job hot maintenance is to be performed
The administrator of the PRIMECLUSTER system shall shut down the node that contains the target equipment, so as to separate it from the operation, and then pass the operation over to field engineers.
For details on how to separate the node from the operation, see "12.2.1 Detaching Resources from Operation."
Field engineers shall confirm the target equipment and perform maintenance of the erroneous equipment (repair or replacement). Operation shall be confirmed by using a test program, etc.
After field engineers complete the maintenance and confirm the operation of the relevant equipment, boot the node and then execute standby restoration for the operation.
For details on standby restoration for the operation, see "12.2.2 Executing Standby Restoration for an Operating Job."
