  9. 9.5.1 Changing a multiple-BB configuration into the 1BB configuration and releasing the connections

9.5.1 Changing a multiple-BB configuration into the 1BB configuration and releasing the connections


9.5.1 Changing a multiple-BB configuration into the 1BB configuration and releasing the connections
Remove the SPARC M10-4S from the existing multiple-BB configuration (direct connections between chassis), change it to the 1BB configuration, and release the connections.
To move the SPARC M10-4S to an expansion rack, stop the entire system and then perform the work.
Note the following points on this work.
  1. All the system setting information will be cleared and reset to the factory defaults.
    Before removing the SPARC M10-4S, save the system setting information with the dumpconfig command. In case of resetting the configuration to the original setting, you can restore the saved setting information to XSCF by using the restoreconfig command.
  2. Multiple SPARC M10-4S units cannot be released from the system by using the initbb command at the same time.
  3. The serial number of the chassis of either the master XSCF or standby XSCF is used as the system serial number. If the serial number of the standby chassis is being used as the system serial number, the initbb command cannot release the standby chassis. In this case, execute the switchscf command to switch the master XSCF.
  4. For the initialization of the chassis of the master XSCF, perform that work at the end.
    Execute the restoredefaults -c factory command to return to the factory defaults, including the CPU Activation key information. Perform this work with a serial connection to the master XSCF.
    For XCP 2041 or later, execute the restoredefaults -c factory -r activation command.
    The key must be reinstalled at initial setup of the XSCF after expansion.
  1. Log in to the master XSCF.
  2. Execute the showhardconf command, and confirm the chassis serial number of the system board (PSB) targeted for release.
    For details, see "A.2.1 Checking the component status."
Note - If the serial number of the chassis of the master XSCF is not being used as the system serial number, execute the switchscf command to switch the master XSCF.
  1. Execute the poweroff command to stop all the physical partitions.
XSCF> poweroff -y -a
PPAR-IDs to power off:00,01,02 03
Continue? [y|n]:y
00:Powering off
01:Powering off
02:Powering off
03:Powering off
  1. Execute the deleteboard command from the master XSCF to release a system board (PSB) from the physical partition configuration.
    The following example releases system boards 00-0, 01-0, 02-0, and 03-0 from the physical partition.
XSCF> deleteboard -c unassign 00-0 01-0 02-0 03-0
PSB#00-0 will be unassigned from PPAR immediately. Continue?[y|n] :y
PSB#01-0 will be unassigned from PPAR immediately. Continue?[y|n] :y
PSB#02-0 will be unassigned from PPAR immediately. Continue?[y|n] :y
PSB#03-0 will be unassigned from PPAR immediately. Continue?[y|n] :y
  1. Execute the showresult command, and confirm the end status of the previously executed deleteboard command.
    In the following example, 0 is returned as the end status, so the execution of the deleteboard command has completed correctly.
XSCF> showresult
0
  1. Execute the showboards command to check the system board (PSB) status.
    In the following example, system boards 00-0, 01-0, 02-0, and 03-0 are in the system board pool.
XSCF> showboards -a
PSB PPAR-ID(LSB) Assignment Pwr Conn Conf Test Fault
---- ------------ ----------- ---- ---- ---- ------- --------

00-0 SP Available n n n Passed Normal
01-0 SP Available n n n Passed Normal
02-0 SP Available n n n Passed Normal
03-0 SP Available n n n Passed Normal
  1. Execute the initbb command from the master XSCF to release the target SPARC M10-4S from the system and initialize it.
    In bb_id, specify the ID (BB-ID) identifying the chassis.
XSCF> initbb -b bb_id
  1. The following example releases BB#03 from the system and initializes it.
XSCF> initbb -b 3
You are about to initialize BB/XB-Box.
NOTE the following.
1. BB/XB-Box is excluded from the system and halted.

2. PPAR-ID of the same value as BB-ID becomes invalid.

Continue? [y|n] :y
Note - After the execution of the initbb command, the target chassis is released from the system and enters the stopped state. Do not disconnect the power cords or various cables until the XSCF STANDBY LED on the panel and the rear READY LED of the target chassis are off.
Note - For the initialization of the chassis of the master XSCF, perform that work at the end.
Execute the restoredefaults -c factory command to return to the factory defaults, including the CPU Activation key information. Perform this work with a serial connection to the master XSCF.
For XCP 2041 or later, execute the restoredefaults -c factory -r activation command.
The key must be reinstalled at initial setup of the XSCF after expansion.
  1. Remove the power cords from the power supply units of the target SPARC M10-4S.
  2. Remove the XSCF BB control cables from the target SPARC M10-4S.
  3. Remove the crossbar cables from the target SPARC M10-4S.
Note - Do not hold the cable part when pulling out the crossbar cable. Pulling the cable part without the connector lock completely released may cause damage.
  1. Remove the XSCF DUAL control cable.
  2. Remove the target SPARC M10-4S from the rack.
    Remove the SPARC M10-4S from the rack by reversing the mounting procedure. For the procedure for mounting in the rack, see "3.4.1 Mounting the SPARC M10-4S in a rack."
