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:
  1. Building block configuration where two or more physical partitions are operating
Table 4-37 shows the workflow for inactive/cold replacement of the CMU.
Table 4-37  Inactive/Cold Replacement Procedure 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).
