5.2.4 Active/Cold Addition Workflow of Memory
5.2.4 Active/Cold Addition Workflow of Memory
You can perform active/cold addition of memory in the following configuration:
- Configuration connecting two or more SPARC M12-2S units to a physical partition
Before adding memory, see "Precautions for memory expansion" in "7.2 Precautions for FRU Expansion."
Table 5-7 shows the workflow for active/cold addition of memory.
Work Order | Task | Reference |
---|---|---|
1 | Checking the operating condition of the system | "9.2.1 Checking the Operation Status of Physical Partitions and Logical Domains" |
2 | Checking the logical domain assignment status of CPU resources mounted in the SPARC M12-2S requiring maintenance | "3.2.4 Checking the Assignment Status of Resources" in the Fujitsu SPARC M12 and Fujitsu M10/SPARC M10 Domain Configuration Guide |
3 | Checking the logical domain assignment status of memory resources mounted in the SPARC M12-2S requiring maintenance | "3.2.4 Checking the Assignment Status of Resources" in the Fujitsu SPARC M12 and Fujitsu M10/SPARC M10 Domain Configuration Guide |
4 | Releasing the logical domain assignment of PCIe cards mounted in the SPARC M12-2S requiring maintenance | "9.3 Releasing I/O Resources From a Logical Domain" |
5 | Releasing the SPARC M12-2S requiring maintenance from the physical partition | "9.4.3 Dynamically Releasing the SPARC M12-2S From the Physical Partition" |
6 | Switching the mode switch on the OPNL to Service | "2.3.2 OPNL Control Function" |
7 | Releasing the SPARC M12-2S requiring maintenance from the building block configuration, and removing the power cords | "9.6.1 Releasing the SPARC M12-2S From the Building Block Configuration" "9.8.2 Removing the Power Cords" |
8 | Removing the CMU from the SPARC M12-2S | "17.4 Removing the CMU or Memory" |
9 | Installing memory in the CMU and installing this unit in the SPARC M12-2S | "17.5 Installing the CMU and Memory" |
10 | Installing the power cords on the SPARC M12-2S requiring maintenance, and incorporating it into the building block configuration | "10.1.1 Installing a Power Cord" "10.4.1 Incorporating the SPARC M12-2S Into a Building Block Configuration" |
11 | Diagnosing the SPARC M12-2S requiring maintenance (*1) | "10.5.1 Diagnosing the SPARC M12 Hardware" |
12 | Diagnosing the XBU and crossbar cable of the SPARC M12-2S requiring maintenance | "10.5.2 Diagnosing the XBU and Crossbar Cable" |
13 | Confirming that there is no problem with the added memory | "10.5.3 Checking the FRU Status After Maintenance" |
14 | Incorporating the SPARC M12-2S into the physical partition | "10.6.1 Incorporating the SPARC M12-2S Into the Physical Partition Using PPAR DR" |
15 | Switching the mode switch on the OPNL to Locked | "2.3.2 OPNL Control Function" |
16 | Assigning the resources of the added SPARC M12-2S to logical domains | "3.2 Operations and Commands Related to Logical Domain Configurations" in the Fujitsu SPARC M12 and Fujitsu M10/SPARC M10 Domain Configuration Guide |
*1 If the CMUU has no memory installed, install memory before installing the CMUU in the SPARC M12-2S. *2 If the memory was added to a SPARC M12-2S with no PCIe cards mounted, no diagnosis is necessary (because diagnosis was performed in the previous step). |
