6.2.3 Active/Cold Removal Workflow of the CMUU


6.2.3 Active/Cold Removal Workflow of the CMUU
You can perform active/cold removal of the CMUU in the following configuration:
  1. Configuration connecting two or more SPARC M12-2S units to a physical partition
Before removing the CMUU, see "Precautions for CMUU removal" in "7.3 Precautions for FRU Reduction."
Table 6-6 shows the workflow for active/cold removal of the CMUU.
Table 6-6  Active/Cold Removal Procedure of the CMUU
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 all the PCIe cards and HDD/SSD mounted in the SPARC M12-2S requiring maintenance "9.3 Releasing I/O Resources From a Logical Domain"
5 Releasing the HDD/SSD and PCIe cards mounted in the SPARC M12-2S requiring maintenance, from the system "9.4 Enabling the Removal of Hardware"
6 Releasing the SPARC M12-2S requiring maintenance from the physical partition "9.4.3 Dynamically Releasing the SPARC M12-2S From the Physical Partition"
7 Switching the mode switch on the OPNL to Service "2.3.2 OPNL Control Function"
8 Confirming that the physical partition and logical domains continue operating "9.2.1 Checking the Operation Status of Physical Partitions and Logical Domains"
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 CMUU "17.4.1 Enabling the Removal of the CMU"
11 Removing the CMUU from the SPARC M12-2S "17.4.2 Removing the CMU"
12 Installing a filler unit in the SPARC M12-2S "17.5.2 Installing the CMU"
13 Assembling the SPARC M12-2S from which the CMUU was removed "17.5.3 Restoring the Server"
14 Incorporating the SPARC M12-2S from which the CMUU was removed into the building block configuration "10.4.1 Incorporating the SPARC M12-2S Into a Building Block Configuration"
15 Diagnosing the SPARC M12-2S from which the CMUU was removed (*1) "10.5.1 Diagnosing the SPARC M12 Hardware"
16 Diagnosing the XBU and crossbar cable, in the building block configuration, of the SPARC M12-2S from which the CMUU was removed "10.5.2 Diagnosing the XBU and Crossbar Cable"
17 Incorporating the SPARC M12-2S into the physical partition "10.6.1 Incorporating the SPARC M12-2S Into the Physical Partition Using PPAR DR"
18 Switching the mode switch on the OPNL to Locked "2.3.2 OPNL Control Function"
19 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"
20 Saving logical domain configuration information "9.1.1 Saving Logical Domain Configuration Information"
*1 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).
*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.
