7.4.1 Active removal


7.4.1 Active removal
 This section describes the workflows for active/hot and active/cold FRU removal. References to detailed descriptions are written in the workflow. See any of them as required. You can perform active/cold removal only for a system with a building block configuration.
Active removal has the following patterns:
Active/hot removal (for a PCIe card)
Active/hot removal can be performed on a PCIe card. Perform the following procedure to remove the unit.
Figure 7-23  Active/hot removal flow (for a PCIe card)
Figure 7-23  Active/hot removal flow (for a PCIe card)
Table 7-24  Active/hot removal work procedure (for a PCIe card)
Item Work procedure Reference
1 Opening the rack door
2 Checking the operating condition of the system and the I/O device usage status "5.3  Checking the Operating Condition and Resource Usage Status"
3 Releasing the assignment of a PCIe card "5.4.1  Releasing the assignment of I/O devices"
4 Enabling the removal of a PCIe card for removal "Enabling the removal of a PCI Express card" in "5.4.2  Enabling the removal of an I/O device
5 Lowering the cable support "5.9.2  Lowering the cable support"
6 Removing the PCIe card for removal "8.3  FRU Removal and Installation Flow"
7 Fixing the cable support "6.1.2  Fixing the cable support"
8 Confirming that there is no problem with the chassis after the removal "6.3.3  Checking the FRU status after maintenance"
9 Closing the rack door  
Active/hot removal (for an internal disk)
Active/hot removal can be performed on an internal disk. Perform the following procedure to remove the unit.

Table 7-25  Active/hot removal work procedure (for an internal disk)
Item Work procedure Reference
1 Opening the rack door
2 Checking the operating condition of the system and the I/O device usage status "5.3  Checking the Operating Condition and Resource Usage Status"
3 Enabling the removal of an internal disk "Enabling the removal of an internal disk" in "5.4.2  Enabling the removal of an I/O device"
4 Removing an internal disk for removal "10.3  FRU Removal and Installation Flow"
5 Confirming that there is no problem with the chassis after the removal "6.3.3  Checking the FRU status after maintenance"
6 Closing the rack door  
Note - You can perform the active/hot removal work for an internal disk only in a RAID configuration.
Active/cold removal (building block configuration only)
Active/cold removal can be performed on the CPU memory unit upper, a PCI Express card, memory, and an internal disk in a building block configuration. Perform the following procedure to remove the unit.

2 Checking the operating condition of the system and the I/O device usage status "5.3  Checking the Operating Condition and Resource Usage Status"
3 Releasing the assignment of a PCIe card "5.4.1  Releasing the assignment of I/O devices"
4 Releasing the chassis requiring maintenance from the partition "5.4.3  Releasing a chassis requiring maintenance from the physical partition"
5 Releasing the chassis requiring maintenance from the system "5.8.1  Releasing of the SPARC M10-4S chassis (possible only in a system with a building block configuration)"
6 Enabling access to the FRU requiring maintenance "5.9  Accessing a FRU"
7 Removing a FRU for removal See the removal procedure for each FRU
"8.3  FRU Removal and Installation Flow"
"9.4  FRU Removal and Installation Flow"
"10.3  FRU Removal and Installation Flow"
8 Restoring the chassis requiring maintenance "6.1  Restoring the Chassis"
9 Incorporating the chassis requiring maintenance into the system "6.2.1  Incorporation of the SPARC M10-4S chassis (possible only in a system with a building block configuration)"
10 Diagnosing the chassis requiring maintenance "6.3.1  Diagnosing the system board" (*1)
"6.3.2  Diagnosing the crossbar unit and crossbar cables"
11 Incorporating the chassis requiring maintenance into a partition "6.5.1  Incorporating a chassis into a physical partition"
12 Confirming that there is no problem with the chassis after the removal "6.3.3  Checking the FRU status after maintenance"
13 Closing the rack door  
*1 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.
