6.4.4 Inactive/Cold Removal Workflow of Memory
6.4.4 Inactive/Cold Removal Workflow of Memory
You can perform inactive/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 6-16 shows the workflow for inactive/cold removal 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 | Releasing the assignment of memory resources according to the total capacity of memory after reduction | "Chapter 3 Operations for Domain Configuration" in the Fujitsu SPARC M12 and Fujitsu M10/SPARC M10 Domain Configuration Guide |
3 | Confirming that you can remove the CMU from which to remove memory (*1) | "9.2.1 Checking the Operation Status of Physical Partitions and Logical Domains" |
4 | Saving logical domain configuration information | "9.1.1 Saving Logical Domain Configuration Information" |
5 | Powering off the physical partition containing the SPARC M12-2S that houses the memory to be removed | "9.5.1 Stopping a Specific Physical Partition" |
6 | Switching the mode switch on the OPNL to Service | "2.3.2 OPNL Control Function" |
7 | Releasing the SPARC M12-2S that houses the memory to be removed, from the building block configuration | "9.6.1 Releasing the SPARC M12-2S From the Building Block Configuration" |
8 | Enabling the removal of the CMU | "17.4.1 Enabling the Removal of the CMU" |
9 | Removing the CMU of the memory to be removed from the SPARC M12-2S | "17.4.2 Removing the CMU" |
10 | Removing the memory from the CMU (*1) | "17.4.3 Removing Memory" |
11 | Installing the CMU from which the memory was removed, in the SPARC M12-2S | "17.5.2 Installing the CMU" |
12 | Assembling the SPARC M12-2S from which the memory was removed | "17.5.3 Restoring the Server" |
13 | Incorporating the SPARC M12-2S from which the memory was removed into the building block configuration | "10.4.1 Incorporating the SPARC M12-2S Into a Building Block Configuration" |
14 | Diagnosing the SPARC M12-2S from which the memory was removed (*2) | "10.5.1 Diagnosing the SPARC M12 Hardware" |
15 | Diagnosing the XBU and crossbar cable, in the building block configuration, of the SPARC M12-2S from which the memory was removed | "10.5.2 Diagnosing the XBU and Crossbar Cable" |
16 | Confirming that there is no problem with the SPARC M12-2S after the removal of the memory | "10.5.3 Checking the FRU Status After Maintenance" |
17 | Switching the mode switch on the OPNL to Locked | "2.3.2 OPNL Control Function" |
18 | Powering on the physical partition containing the SPARC M12-2S that underwent maintenance | "10.9.1 Starting the System With an XSCF Command" |
19 | Checking the operating condition of the physical partition and logical domains (*3) | "9.2.1 Checking the Operation Status of Physical Partitions and Logical Domains" |
20 | 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 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). *3 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. |
