4.6.1 System-Stopped/Cold Replacement Workflow of the XSCFU


4.6.1 System-Stopped/Cold Replacement Workflow of the XSCFU
Table 4-52 shows the workflow for system-stopped/cold replacement of the XSCFU.
Table 4-52  System-Stopped/Cold Replacement Procedure of the XSCFU
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 XSCFU to be replaced "8.2 Troubleshooting"
3 Confirming that the XSCFU to be replaced is the standby or slave XSCF and is currently replaceable (*1) "Table 2-16 XSCFU LEDs and Their States"
4 Stopping all physical partitions "9.5.2 Stopping All Physical Partitions"
5 Switching the mode switch on the OPNL to Service "2.3.2 OPNL Control Function"
6 Removing the power cords of all the SPARC M12-2/M12-2S units "9.8.2 Removing the Power Cords"
7 Removing the XSCFU from the SPARC M12-2/M12-2S "11.4 Removing the XSCFU"
8 Switching the SD card (*2) "11.5 Switching an SD Card"
9 Installing the XSCFU in the SPARC M12-2/M12-2S "11.6 Installing the XSCFU"
10 Installing the power cords on all the SPARC M12-2/M12-2S units (*3)(*4)(*5) "10.1.1 Installing a Power Cord"
11 Checking the XCP firmware version (*6) "11.7 Checking the XCP Firmware Version"
"11.8 Checking the XCP Firmware Version (Building Block Configuration)
12 Confirming that there is no problem with the replacement XSCFU "10.5.3 Checking the FRU Status After Maintenance"
13 Switching the mode switch on the OPNL to Locked "2.3.2 OPNL Control Function"
14 Powering on the physical partitions "10.9.1 Starting the System With an XSCF Command"
15 Checking the operating condition of the system "9.2.1 Checking the Operation Status of Physical Partitions and Logical Domains"
*1 Before replacing the XSCFU, confirm that the READY LED of the XSCFU is lit in green or off. If the READY LED of the XSCFU is blinking, wait until the LED stays lit or is turned off.
- If the XSCFU requiring replacement is not running when the physical partition containing the XSCFU is powered on, perform active/hot replacement.
- If the physical partition containing the XSCFU requiring replacement is off, you can replace the XSCFU even when it is not running. To do so, proceed to "5. Switching the mode switch on the OPNL to Service."

*2 If the SD card installed in the maintenance part will be used, this work is not required.

*3 In a system with a building block configuration, the XCP firmware version may be different between the maintenance part and the existing system. If so, the message "XSCF firmware update now in progress. BB#xx, please wait for XSCF firmware update complete." appears at login to the XSCF. Then, the XCP firmware version will be automatically matched. The version matching takes about 50 minutes. Execute the showlogs monitor command, and check for the "XCP firmware version synchronization completed" message. The displayed message indicates the completion of XCP firmware matching.

*4 If the SD card installed in the maintenance part was used in "8. Switching the SD card," the "SCF:Gaps between BB-ID" message may appear in the error log. If so, ignore the message.

*5 If the "SCF:SCF Diagnosis initialize RTC" message appears in the error log, ignore the message.

*6 If you switched the SD card in "8. Switching the SD card," this step is not necessary.
