4.2.9 Active/Cold Replacement Workflow of the CMU
4.2.9 Active/Cold Replacement Workflow of the CMU
You can perform active/cold replacement of the CMU in the following configuration:
- Configuration connecting two or more SPARC M12-2S units to a physical partition
Before replacing the CMU, see "Precautions for CMU and memory replacement" in "7.1 Precautions for FRU Replacement."
Table 4-16 shows the workflow for active/cold replacement of the CMU.
Work Order | Task | Reference |
---|---|---|
1 | Checking the operating condition of the system and the I/O device usage status | "9.2 Checking the Operation Status and Resource Usage Status of Oracle Solaris" |
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 I/O resources of the SPARC M12-2S requiring maintenance from a logical domain | "9.3 Releasing I/O Resources From a Logical Domain" |
5 | Releasing the SPARC M12-2S requiring maintenance from the physical partition | "9.4.3 Dynamically Releasing the SPARC M12-2S From the Physical Partition" |
6 | 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" |
7 | Placing the SPARC M12-2S requiring maintenance into the cold state, and removing the CMU from the SPARC M12-2S | "17.4 Removing the CMU or Memory" |
8 | Installing the CMU in the SPARC M12-2S, and placing the SPARC M12-2S that required maintenance into the hot state | "17.5 Installing the CMU and Memory" |
9 | Incorporating the SPARC M12-2S that required maintenance into the building block configuration | "10.4.1 Incorporating the SPARC M12-2S Into a Building Block Configuration" |
10 | Diagnosing the SPARC M12-2S with the replacement CMU (*2) | "10.5.1 Diagnosing the SPARC M12 Hardware" |
11 | Diagnosing the XBU and crossbar cable of the SPARC M12-2S with the replacement CMU | "10.5.2 Diagnosing the XBU and Crossbar Cable" |
12 | Confirming that there is no problem with the replacement CMU | "10.5.3 Checking the FRU Status After Maintenance" |
13 | Incorporating the SPARC M12-2S that required maintenance into the physical partition | "10.6.1 Incorporating the SPARC M12-2S Into the Physical Partition Using PPAR DR" |
14 | Incorporating I/O resources of the SPARC M12-2S requiring maintenance into a logical domain (*1) | "10.7 Incorporating I/O Resources Into a Logical Domain" |
15 | Checking the operating condition of the system and the I/O device usage status | "9.2 Checking the Operation Status and Resource Usage Status of Oracle Solaris" |
*1 If the replaced CMUL had the hardware RAID setting enabled, enable the setting again. *2 If the replaced CMUU was in a SPARC M12-2S with no PCIe cards mounted, or if the CMUL was replaced, no diagnosis is necessary (because diagnosis was performed in the previous step). |
