Table 7-7 Active/cold replacement work procedure (building block configuration only)
Item Work procedure
1 Opening the rack door
2 Checking the operating condition of the
system and the I/O device usage status
3 Releasing the assignment of a PCIe card
4 Releasing the chassis requiring maintenance
from the partition
5 Releasing the chassis requiring maintenance
from the system
6 Enabling access to the FRU requiring
maintenance
7 Replacing a faulty FRU
8 Restoring the chassis requiring maintenance
9 Incorporating the chassis requiring
maintenance into the system
10 Diagnosing the chassis requiring
maintenance
11 Incorporating the chassis requiring
maintenance into a partition
12 Confirming that there is no problem with
the replacement FRU
13 Closing the rack door
*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 in "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. Lastly, restore the
system.
*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 "11. Incorporating the chassis requiring maintenance into a partition." 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 Normally, 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.
