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:
  1. Configuration connecting two or more SPARC M12-2S units to a physical partition
Table 4-16 shows the workflow for active/cold replacement of the CMU.

*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).
