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:
- 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.
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. |
