6.4.3 Inactive/Cold Removal Workflow of the CMUU


6.4.3 Inactive/Cold Removal Workflow of the CMUU
You can perform inactive/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 6-15 shows the workflow for inactive/cold removal of the CMUU.
Table 6-15  Inactive/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 Powering off the physical partition containing the SPARC M12-2S that houses the CMUU to be removed "9.5.1 Stopping a Specific Physical Partition"
3 Switching the mode switch on the OPNL to Service "2.3.2 OPNL Control Function"
4 Releasing the SPARC M12-2S that houses the CMUU to be removed, from the building block configuration "9.6.1 Releasing the SPARC M12-2S From the Building Block Configuration"
5 Enabling the removal of the CMUU "17.4.1 Enabling the Removal of the CMU"
6 Removing the CMUU from the SPARC M12-2S "17.4.2 Removing the CMU"
7 Installing a filler unit in the SPARC M12-2S "17.5.2 Installing the CMU"
8 Assembling the SPARC M12-2S from which the CMUU was removed "17.5.3 Restoring the Server"
9 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"
10 Diagnosing the SPARC M12-2S from which the CMUU was removed (*1) "10.5.1 Diagnosing the SPARC M12 Hardware"
11 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"
12 Confirming that there is no problem with the system from which the CMUU was removed "10.5.3 Checking the FRU Status After Maintenance"
13 Reconfiguring the I/O bus as required (*2) "3.2.18 Configuring an I/O Device" in the Fujitsu SPARC M12 and Fujitsu M10/SPARC M10 Domain Configuration Guide
14 Switching the mode switch on the OPNL to Locked "2.3.2 OPNL Control Function"
15 Powering on the physical partition containing the SPARC M12-2S that underwent maintenance "10.9.1 Starting the System With an XSCF Command"
16 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"
17 Saving logical domain configuration information "9.1.1 Saving Logical Domain Configuration Information"
*1 If the CMUU 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 When reconfiguring the I/O bus, you may need to reconfigure the logical domains.
*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.
