  9. 6.2.4 Active/Cold Removal Workflow of Memory

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:
  1. Configuration connecting two or more SPARC M12-2S units to a physical partition
Table 6-7 shows the workflow for active/cold removal of memory.
Table 6-7  Active/Cold Removal Procedure of Memory
Work Order Task Reference

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"

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).
