  9. 6.4.4 Inactive/Cold Removal Workflow of Memory

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:
  1. Configuration connecting two or more SPARC M12-2S units to a physical partition
Table 6-16 shows the workflow for inactive/cold removal of memory.
Table 6-16  Inactive/Cold Removal Procedure 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.
