7.2.2 Inactive replacement


7.2.2 Inactive replacement
This section describes the workflows for inactive/hot and inactive/cold FRU replacement. References to detailed descriptions are written in the workflow. See any of them as required. You can perform the operations here only for a system with a building block configuration.
Inactive replacement has the following patterns:
Inactive/hot replacement (for a power supply unit or fan unit)
Inactive/hot replacement can be performed on a power supply unit and a fan unit. Perform the following procedure to replace the unit.

*1 Simultaneous replacement of the CPU memory unit and PSU backplane unit is prohibited. To replace the CPU memory unit and PSU backplane unit, first replace either of the units and perform the work up to "9. Incorporating the chassis requiring maintenance into the system." Then, return to "5. Releasing the chassis requiring maintenance from the system," and replace the other unit.
*2 If a CPU memory unit lower is replaced in the system of the hardware RAID volume in a hardware RAID configuration using internal disks, you need to reactivate the hardware RAID volume before starting Oracle Solaris. Start Oracle Solaris on the control domain as described in "13. Powering on the chassis requiring maintenance." For details, see "14.2.11  Re-enabling a Hardware RAID Volume" in the Fujitsu SPARC M12 and Fujitsu M10/SPARC M10 System Operation and Administration Guide.
*3 The testsb command is executed during replacefru command processing. However, if that is canceled, diagnose the system board before incorporating the chassis requiring maintenance into the physical partition.
