4.4.9 Inactive/Cold Replacement Workflow of the CMU
4.4.9 Inactive/Cold Replacement Workflow of the CMU
You can perform inactive/cold replacement of the CMU in the following configuration:
- Building block configuration where two or more physical partitions are operating
Before replacing the CMU, see "Precautions for CMU and memory replacement" in "7.1 Precautions for FRU Replacement."
Table 4-37 shows the workflow for inactive/cold replacement of the CMU.
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 | Confirming the CMU to be replaced | "8.2 Troubleshooting" |
3 | Checking the operation status of the SPARC M12-2S that houses the CMU to be replaced | "2.4.2 System Locator" |
4 | Powering off the physical partition containing the SPARC M12-2S that houses the CMU requiring maintenance | "9.5.1 Stopping a Specific Physical Partition" |
5 | Switching the mode switch on the OPNL to Service | "2.3.2 OPNL Control Function" |
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 requiring maintenance (*2) | "10.5.1 Diagnosing the SPARC M12 Hardware" |
11 | Diagnosing the XBU and crossbar cable of the SPARC M12-2S requiring maintenance | "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 | Switching the mode switch on the OPNL to Locked, and powering on the physical partition containing the SPARC M12-2S that has undergone maintenance | "10.8 Powering on a Physical Partition" |
14 | Checking the operating condition of the system | "9.2.1 Checking the Operation Status of Physical Partitions and Logical Domains" |
*1 If you replaced a CMU that uses the hardware RAID function, enable the hardware RAID function before starting Oracle Solaris. *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). |
