6.2.4 Active/Cold Removal Workflow of Memory
6.2.4 Active/Cold Removal Workflow of Memory
You can perform active/cold removal of memory in the following configuration:
- Configuration connecting two or more SPARC M12-2S units to a physical partition
Before removing the memory, see "Precautions for memory reduction" in "7.3 Precautions for FRU Reduction."
Table 6-7 shows the workflow for active/cold removal of memory.

9 | Releasing the SPARC M12-2S requiring maintenance from the building block configuration | "9.6.1 Releasing the SPARC M12-2S From the Building Block Configuration" |
10 | Enabling the removal of the CMU of the memory to be removed | "17.4.1 Enabling the Removal of the CMU" |
11 | Removing the CMU of the memory to be removed from the SPARC M12-2S | "17.4.2 Removing the CMU" |
12 | Removing the memory from the CMU (*1) | "17.4.3 Removing Memory" |
13 | Installing the CMU from which the memory was removed, in the SPARC M12-2S | "17.5.2 Installing the CMU" |
14 | Assembling the SPARC M12-2S from which the memory was removed | "17.5.3 Restoring the Server" |

18 | Incorporating the SPARC M12-2S into the physical partition | "10.6.1 Incorporating the SPARC M12-2S Into the Physical Partition Using PPAR DR" |
19 | Switching the mode switch on the OPNL to Locked | "2.3.2 OPNL Control Function" |
20 | Checking the operating condition of the physical partition and logical domains (*2) | "9.2.1 Checking the Operation Status of Physical Partitions and Logical Domains" |
21 | Saving logical domain configuration information | "9.1.1 Saving Logical Domain Configuration Information" |
*1 Observe the installation rules to remove memory. For details, see "2.2 Checking the Memory Configuration Rules." *2 Reconfigure logical domains as required. For details, see "Chapter 3 Operations for Domain Configuration" in the Fujitsu SPARC M12 and Fujitsu M10/SPARC M10 Domain Configuration Guide. *3 If the memory was removed from a SPARC M12-2S with no PCIe cards mounted, no diagnosis is necessary (because diagnosis was performed in the previous step). |
